32147628 Several drugs such as chloroquine, arbidol, remdesivir, and favipiravir are currently undergoing clinical studies to test their efficacy and safety in the treatment of coronavirus disease 2019 (COVID-19) in China; some promising results have been achieved thus far.
32243270 This review summarizes the current evidence of potential therapeutic agents, such as lopinavir/ritonavir, remdesivir, favipiravir, chloroquine, hydroxychloroquine, interferon, ribavirin, tocilizumab and sarilumab.
32246834 Favipiravir, a purine nucleic acid analog and potent RdRp inhibitor approved for use in influenza, is also considered in several clinical trials. […] Herein, we summarized the pharmacokinetic characteristics of favipiravir and possible drug-drug interactions from the view of drug metabolism. […] We hope this will be helpful for the design of clinical trials for favipiravir in COVID-2019, as data regarding in vitro virus inhibition and efficacy in preclinical animal studies are still not available.
32251767 Ribavirin or favipiravir that are currently evaluated under clinical trials showed no inhibition at 100 μM.
32256547 We identified 24 clinical trials, involving more than 20 medicines, such as human immunoglobulin, interferons, chloroquine, hydroxychloroquine, arbidol, remdesivir, favipiravir, lopinavir, ritonavir, oseltamivir, methylprednisolone, bevacizumab, and traditional Chinese medicines (TCM). […] Se identificaron 24 ensayos clínicos relacionados con más de 20 medicamentos, como inmunoglobulina humana, interferones, cloroquina, hidroxicloroquina, arbidol, remdesivir, favipiravir, lopinavir, ritonavir, oseltamivir, metilprednisolona, bevacizumab y medicina tradicional china. […] Foram identificados 24 ensaios clínicos envolvendo mais de 20 medicamentos, tais como imunoglobulina humana, interferons, cloroquina, hidroxicloroquina, arbidol, remdesivir, favipiravir, lopinavir, ritonavir, oseltamivir, metilprednisolona, bevacizumabe e medicamentos chineses tradicionais.
32277367 Antiviral drugs like lopinavir/ritonavir, favipiravir and remdesivir are also being explored.
32284326 In this regard, the triphosphate forms of 2’-C-methylated compounds, including sofosbuvir, approved for the management of hepatitis C virus infection, and the broad-acting antivirals favipiravir and ribavirin, exhibited significant deficits.
32290293 The initial clinical studies revealed the promising therapeutic potential of several of such drugs, including favipiravir, a broad-spectrum antiviral drug that interferes with the viral replication, and hydroxychloroquine, the repurposed antimalarial drug that interferes with the virus endosomal entry pathway.
32293834 The most frequently used agents both in Turkey and all over the world including chloroquine, hydroxychloroquine, lopinavir/ritonavir, favipiravir and remdesivir will be reviewed here .
32297571 Inaddition, remdesivir, which has been previously administered to Ebola virus patients, has alsoproven effective in the U.S. against coronavirus, while antimalarial chloroquine and hydroxy-chloroquine, favipiravir and co-administered darunavir and umifenovir (in patient therapies)were also recently recorded as having anti-SARS-CoV-2 effects.
32307245 The other excellent anti-influenza RdRp inhibitor favipiravir is also being clinically evaluated for its efficacy in COVID-19 patients.
32329520 Drug repositioning may offer a strategy and a number of drugs have been repurposed, including lopinavir/ritonavir, remdesivir, favipiravir and tocilizumab.
32336586 There are currently no therapeutic drugs available that are directly active against SARS-CoV-2; however, several antivirals (remdesivir, favipiravir) and antimalarials (chloroquine, hydroxychloroquine) have emerged as potential therapies.
32338164 The results show the effectiveness of Sofosbuvir, Ribavirin, Galidesivir, Remdesivir, Favipiravir, Cefuroxime, Tenofovir, and Hydroxychloroquine, in binding to SARS-CoV-2 RdRp.
32346491 Herein, we examine the effects of Favipiravir (FPV) versus Lopinavir (LPV)/ritonavir (RTV) for the treatment of COVID-19.
32360480 Further, chloroquine and hydroxychloroquine, and off-label antiviral drugs, such as the nucleotide analogue remdesivir, HIV protease inhibitors lopinavir and ritonavir, broad-spectrum antiviral drugs arbidol and favipiravir as well as antiviral phytochemicals available to date may limit spread of SARS-CoV-2 and morbidity and mortality of COVID-19 pandemic.
32372695 Similarly, other investigational drugs such as favipiravir and lopinavir/ritonavir can prolong QT interval and cause Torsade de Pointes.
32392072 Furthermore, we demonstrate the binding poses of three viral RdRp inhibitors (Galidesivir, Favipiravir, and Penciclovir), which were recently reported to have clinical significance for SARS-CoV-2.
32394467 Favipiravir increases clinical recovery and reduces respiratory problems and has a stronger antiviral effect than LPV/r. currently, appropriate treatment for patients with COVID-19 is an ACE2 inhibitor and a clinical problem reducing agent such as favipiravir in addition to hydroxychloroquine and corticosteroids.
32395418 These drugs and therapeutic agents include antiviral agents (remdesivir, hydroxychloroquine, chloroquine, lopinavir, umifenovir, favipiravir, and oseltamivir), and supporting agents (Ascorbic acid, Azithromycin, Corticosteroids, Nitric oxide, IL-6 antagonists), among others.
32397911 In particular, hydroxychloroquine, remdesivir, favipiravir, arbidol, tocilizumab and bevacizumab have shown promising results.
32399094 SARS-CoV-2 Mpro was docked with all statins, while antiviral and antiretroviral drugs - favipiravir, nelfinavir, and lopinavir - were used as standards for comparison. […] The binding energies obtained from the docking of 6LU7 with native ligand favipiravir, nelfinavir, lopinavir, simvastatin, rosuvastatin, pravastatin, pitavastatin, lovastatin, fluvastatin, and atorvastatin were -6.8, -5.8, -7.9, -7.9, -7.0, -7.7, -6.6, -8.2, -7.4, -7.7, and -6.8 kcal/mol, respectively.
32405421 Favipiravir is an antiviral previously indicated for influenza and Ebola, which has shown some promise in early trials for treatment of COVID-19. […] We aim to review existing favipiravir safety evidence, which is vital to informing the potential future use of favipiravir in COVID-19. […] All studies assessing the use of favipiravir in humans by 27 March 2020 were considered for inclusion. […] Twenty-nine studies were identified as potential sources of evidence of the clinical safety of favipiravir. […] The proportions of grade 1-4 AEs on favipiravir was 28.2% vs 28.4% (P = n.s.) in the comparison arms. […] The proportion of discontinuations due to AEs on favipiravir was 1.1% vs 1.2% (P = n.s.) in the comparison arms. […] There were significantly fewer gastrointestinal AEs occurring on favipiravir vs comparators [8.7% vs 11.5%; P = 0.003]. […] Favipiravir showed significantly more uric acid elevations than comparators [5.8% vs 1.3%; P<0.0001]. […] Favipiravir demonstrates a favourable safety profile regarding total and serious AEs. […] Favipiravir may be safe and tolerable in short-term use, but more evidence is needed to assess the longer-term effects of treatment. […] Given the limitations of the evidence and unresolved safety concerns, caution is warranted in the widespread use of favipiravir against pandemic COVID-19.
32405423 Minimum estimated costs of production were US $0.93/day for remdesivir, $1.45/day for favipiravir, $0.08/day for hydroxychloroquine, $0.02/day for chloroquine, $0.10/day for azithromycin, $0.28/day for lopinavir/ritonavir, $0.39/day for sofosbuvir/daclatasvir and $1.09/day for pirfenidone.
32425246 The only FDA approved drug to treat COVID-19 is remdesivir, and other off-label medications used include chloroquine and hydroxychloroquine, tocilizumab, lopinavir/ritonavir, favipiravir, convalescent plasma therapy, azithromycin, vitamin C, corticosteroids, interferon and colchicine.
32448818 The additive effects of interferons on the inhibitory effects of other candidate drugs to treat SARS-CoV-2 infection, such as lopinavir, ritonavir and favipiravir, have also been studied.
32473756 We report the first two cases of Coronavirus Disease 2019 (COVID-19) who were receiving intensive care including favipiravir, and were clinically diagnosed with neuroleptic malignant syndrome (NMS) to focus attention on NMS in COVID-19 management. […] Case 1: A 46-year-old-man with acute respiratory distress syndrome (ARDS) caused by COVID-19 infection was being administered favipiravir. […] Case 2: A 44-year-old-man with ARDS caused by COVID-19 infection was being treated with favipiravir. […] NMS diagnosis was confirmed, and both, favipiravir and risperidone were discontinued on day 8. […] The mechanism underlying the occurrence of NMS in COVID-19 patients treated with favipiravir remains unknown.
32475019 The anti-retroviral drug favipiravir (FPV) has been experimentally used for COVID-19 treatment since March 2020 in Japan.
32486229 In this study, the bioactivity of some selected heterocyclic drugs named Favipiravir (1), Amodiaquine (2), 2’-Fluoro-2’-deoxycytidine (3), and Ribavirin (4) was evaluated as inhibitors and nucleotide analogues for COVID-19 using computational modeling strategies.
32503657 We will enroll patients who are discharged after treatment, whose nucleic acid test has changed from negative to positive during the screening visit, regardless of the severity of the symptoms, to investigate the mechanism, clinical outcome and therapeutic efficacy with Favipiravir patients with Corona virus Disease 2019. […] Favipiravir is an anti-viral agent that selectively and potently inhibits the RNA-dependent RNA polymerase, it has been used for treatment of some life-threatening infections such as Ebola virus, Lassa virus and rabies. […] Favipiravir group (experimental): Favipiravir 1600mg each dose, twice a day on the 1st day; 600mg each dose, twice a day from the 2nd to the 7th day, Oral administration, the maximum number of days taken will be no more than 14 days plus routine treatment for COVID-19. […] Trial participants, investigators, care givers, outcome assessors, and date analysts are not blinded to group assignment. 210 patients are expected to be enrolled and allocated according to the ratio of 2 (Favipiravir group, n=140): 1(regular treatment group, n=70).
32514228 Certain drugs that are clinically approved for other diseases were tested against COVID-19 as chloroquine, hydroxychloroquine, ivermectin, favipiravir, ribavirin, and remdesivir.
32526208 Nucleotide analog inhibitors, including broad-spectrum remdesivir and favipiravir, have shown promise in in vitro assays and some clinical studies for COVID-19 treatment, this despite an incomplete mechanistic understanding of the viral RNA-dependent RNA polymerase nsp12 drug interactions.
32532939 Hydroxychloroquine, lopinavir/ritonavir, remdesivir, umifenovir, favipiravir, ribavirin and beta-interferon-1 gave rise to variable but still inconsistent proof of clinical efficacy in the treatment of COVID-19.
32536670 In light of the recent pandemic, favipiravir (Avigan®), a purine nucleic acid analog and antiviral agent approved for use in influenza in Japan, is being studied for the treatment of coronavirus disease 2019 (COVID-19). […] Increase in blood uric acid level is a frequent side effect of favipiravir. […] Here, we discussed the mechanism of blood uric acid elevation during favipiravir treatment. […] Favipiravir is metabolized to an inactive metabolite M1 by aldehyde oxidase and xanthine oxidase, and excreted into urine. […] Favipiravir and M1 act as moderate inhibitors of organic anion transporter 1 and 3 (OAT1 and OAT3), which are involved in uric acid excretion in the kidney. […] Thus, favipiravir is thought to decrease uric acid excretion into urine, resulting in elevation of uric acid levels in blood. […] Elevated uric acid levels were returned to normal after discontinuation of favipiravir, and favipiravir is not used for long periods of time for the treatment of viral infection. […] Nevertheless, the adverse effect of favipiravir might be clinically important in patients with a history of gout, hyperuricemia, kidney function impairment (in which blood concentration of M1 increases), and where there is concomitant use of other drugs affecting blood uric acid elevation.
32538209 We encourage giving more attention to favipiravir, remdesivir, and measles vaccine.
32554953 Several anti-viral drugs such as RNA dependent RNA polymerase inhibitors (remdesivir, favipiravir, ribavirin), protease inhibitors (lopinavir, ritonavir) and drugs targeting endocytic pathway (hydroxychloroquine) are being evaluated for COVID-19 but standard therapeutics yet not available.
32555446 According to the information that we have collected so far, this article provides an overview of potential therapeutic drugs and compounds with much attention, including favipiravir and hydroxychloroquine, as well as traditional Chinese medicine, which have been reported with good clinical treatment effects.
32556649 Interferon beta-1b subcutaneous injection was initiated immediately to enhance anti-viral therapy, and favipiravir on ICU day 10 upon availability.
32561148 Novel experimental therapies, such as remdesivir and favipiravir, are also actively being investigated for antiviral efficacy.
32564306 To the best of our knowledge, favipiravir and anti-cytokine treatments have not been previously reported in a kidney transplant recipient with SARS-CoV-2 infection before.
32572376 Based on the previous experiences with similar coronavirus management and present preliminary data from uncontrolled studies, drugs like chloroquine, hydroxychloroquine, remdesivir, lopinavir/ritonavir, and favipiravir have been recommended by the researchers to manage COVID-19.
32572842 In particular, information has spread about some drugs approved for other indications (chloroquine, hydroxychloroquine, nonsteroidal anti-inflammatory drugs, angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists, favipiravir, and umifenovir) that could have led to inappropriate and therefore hazardous use.
32573355 In addition to the selected compounds, 4 nucleoside analogs of anti-viral (Raltgravir, Maraviroc and Favipiravir) and anti-inflammatory (Prednisolone) drugs were selected for further investigations.
32580215 The patient was given NIMV (non-invasive mechanical ventilation), and hydroxychloroquine, favipiravir and azithromycin in isolation intensive care, with the diagnosis of severe pneumonia.
32584236 Likewise, protease inhibitors, including lopinavir/ritonavir, favipiravir, and nucleoside analogue remdesivir were proposed to be the potential drug candidates in COVID-19 management.
32585765 Darunavir together with ritonavir, hydroxychloroquine, azithromycin, and favipiravir were initiated on the first day of admission at primary hospital.
32409433 Antivirals to treat influenza (oseltamivir) have limited activity against SARS-CoV-2, but favipiravir and umifenovir, two influenza antivirals available internationally, may have distinct viral targets and require further investigation.
32595349 The antiviral drugs used for viral diseases excluding COVID-19 infection are Ramdesvir, Favipiravir, and Ribavarin, and antimalarial agents (Chloroquine & Hydroxychloroquine) are being administered to the patients for redemption of this infection.
32612432 As ribavirin and favipiravir have teratogenic effects, there are some debates on the use of ribavirin in severe cases.
32612804 A preliminary search identified the following drugs as being used to treat COVID-19 symptoms: atazanavir (ATV), azithromycin (AZI), chloroquine (CLQ)/hydroxychloroquine (HCLQ), dipyridamole, famotidine (FAM), favipiravir, lopinavir/ritonavir (LPV/r), nitazoxanide, remdesivir, ribavirin and tocilizumab.
32628137 ACEi exposure was associated with milder infiltrations seen on baseline CT, lower C-reactive protein and ferritin, higher monocytes, shorter hospitalization, and less requirement for specific empirical treatments (favipiravir and meropenem).
32629804 Therapeutics with particularly high potential efficacy for repurposing include camostat mesylate, remdesivir, favipiravir, tocilizumab, baricitinib, convalescent plasma, and humanized monoclonal antibodies. […] In early research, the targeted antivirals remdesivir and favipiravir appear to benefit patients by decreasing viral replication; clinical trials suggest that remdesivir speeds recovery from COVID-19.
32631826 These repurposed drugs have mainly included remdesivir, favipiravir, lopinavir-ritonavir, ribavirin, interferons, and hydroxychloroquine.
32643436 Initial findings from antivirals such as remdesivir, favipiravir, danoprevir or lopinavir with ritonavir are presented.
32649262 In particular, chloroquine and hydroxychloroquine, azithromycin, as well as antiviral drugs such as remdesivir, favipiravir and lopinavir can all present potential ototoxic side effects.
  1. Researchers’ claim that nutrition and immunity enhancers and treatment plans such as arbidol, lopinavir/ritonavir, convalescent plasma and mesenchymal stem cells and drugs including remdesivir, hydroxychloroquine, azithromycin and favipiravir are effective against COVID-19.
32682787 Amongst these RNA-dependent RNA polymerase inhibitors (favipiravir and remdesivir) and steroids especially dexamethasone showed promising effects.
32682788 Several drugs such as Remdesivir, Hydroxychloroquine, Chloroquine, Ribavirin, Ritonavir, Lopinavir, Favipiravir, Interferons, Bevacizumab, Azithromycin, etc. are currently under clinical trials.
32684351 In this article, we reviewed the current options for COVID-19 therapy including small molecules such as Remdesivir, Favipiravir, Lopinavir/Ritonavir etc, peptide inhibitors of ACE2, Traditional Chinese Medicines and Biologics such as SARS-CoV-2-specific neutralizing antibodies, mesenchymal stem cells and vaccines etc.
32685234 Currently, the management of patients with COVID-19 depends mainly on repurposed drugs which include chloroquine, hydroxychloroquine, lopinavir/ritonavir, ribavirin, remdesivir, favipiravir, umifenovir, interferon-α, interferon-β and others.
32711596 We started a study on the molecular docking of six potential pharmacologically active inhibitors compounds that can be used clinically against the COVID-19 virus, in this case, remdesivir, ribavirin, favipiravir, galidesivir, hydroxychloroquine and chloroquine interacting with the main COVID-19 protease in complex with a COVID-19 N3 protease inhibitor. […] The highest values of affinity energy found in order from highest to lowest were chloroquine (CHL), hydroxychloroquine (HYC), favipiravir (FAV), galidesivir (GAL), remdesivir (REM) and ribavirin (RIB).
32717568 The results of clinical trials point to the potential clinical efficacy of antivirals, especially remdesivir (GS-5734), lopinavir/ritonavir, and favipiravir.
32718127 In this case series, 13.2% patients were treated with hydroxychloroquine alone, 64.9% with hydroxychloroquine plus azithromycin, and 18.4% with regimens including favipiravir.
32725382 We found promising in vitro evidence for remdesivir, (hydroxy)chloroquine and favipiravir against SARS-CoV-2; potential clinical benefit in SARS-CoV-2 with remdesivir, the combination of lopinavir/ritonavir (LPV/r) plus ribavirin; and strong evidence for LPV/r plus ribavirin against Middle East Respiratory Syndrome (MERS) for post-exposure prophylaxis in healthcare workers.
32727996 He received favipiravir for compassionate use for 14 days. […] Favipiravir may induce not only hyperuricemia but also acute gouty arthritis.
32731139 During their treatment with hydroxychloroquine (HCQ), azithromycin and favipiravir, ventricular tachycardia episodes were observed in in two COVID-19 patients during their hospitalization in the intensive care unit.
32735546 The top 10 candidates according to our algorithm are hydroxychloroquine, azithromycin, chloroquine, ritonavir, losartan, remdesivir, favipiravir, methylprednisolone, rapamycin, and tilorone dihydrochloride.
32735768 Supportive care and management of the complications that are caused mainly by inflammation might be the key to greater survival rates and shorter hospitalization (e.g., the use of remdesivir, lopinavir, ritonavir, umifenovir (arbidol), oseltamivir, ganciclovir, favipiravir, darunavir, hydroxychloroquine, chloroquine, colchicine, azithromycin, anakinra, canakinumab, tocilizumab, siltuximab, sarilumab, Type 1 interferon, interferon β-1a, interferon α- 2b, baricitinib, ruxolitinib, fedratinib, methylprednisolone and dexamethasone).
32737100 This systematic review and meta-analysis will evaluate studies of the effects of favipiravir in COVID-19 pneumonia. […] We will search electronic databases including LitCovid hub, PubMed, Scopus, ISI Web of Sciences, Cochrane and Embase using keywords related to COVID-19 and favipiravir. […] All randomised clinical trials investigating the safety and efficacy of favipiravir compared with other control groups for the treatment of patients with confirmed infection with SARS-CoV-2 will be included. […] All findings of this systematic review and meta-analysis will help identify the safety and efficacy of favipiravir for patients with COVID-19.
32742970 Out of 32 patients, 9 patients also received favipiravir.
32746653 Here, we summarized and evaluated the current treatment drugs and regimens, and put forward the treatment recommendations, including using the potential repurposed or experimental drugs against COVID-19, e.g. chloroquine (CQ), hydroxychloroquine (HCQ), lopinavir/ritonavir (LPV/r), remdesivir (RDV), and favipiravir (FPV).
32750019 The efficacy and tolerability of hidroxychloroquin remains to be also questionable; enroll patients into clinical trial with remdesivir or favipiravir if available.
32752944 Therefore, this review focuses on the current use of various drugs as single agents (hydroxychloroquine, ivermectin, azithromycin, favipiravir, remdesivir, umifenovir, teicoplanin, nitazoxanide, doxycycline, and dexamethasone) or in combinations with immunomodulators additionally.
32754388 In this article, we have compiled comprehensive data on many candidate drugs such as remdesivir, favipiravir, ribavirin, umifenovir, arbidol, lopinavir, ritonavir, baricitinib, hydroxychloroquine, nitazoxanide, azithromycin, baloxavir, oseltamivir, losartan, and tocilizumab.
32763956 Despite starting standard dose of favipiravir, his respiratory condition deteriorated during hospitalisation. […] On day 11, he was successfully extubated, subsequently completing a 14-day course of favipiravir.
32768505 These include anti-viral agents (remdesivir, ribavirin, lopinavir-ritonavir, favipiravir, chloroquine, hydroxychloroquine, oseltamivir, umifenovir), immunomodulatory agents (tocilizumab, interferons, plasma transfusions), and adjunctive agents (azithromycin, corticosteroids), among other miscellaneous agents.
32770240 In May 2020 the Russian Ministry of Health granted fast-track marketing authorization to RNA polymerase inhibitor AVIFAVIR (favipiravir) for the treatment of COVID-19 patients.
32771797 In this review, we summarized the real-time information of 2019-nCoV treatment methods and mainly focused on the chemical drugs including lopinavir/ritonavir, chloroquine, hydroxychloroquine, arbidol, remdesivir, favipiravir and other potential innovative active molecules.
32773212 Favipiravir demonstrated good recovery in some of the cases of COVID-19.
32777318 The skin reactions of antimalarials (chloroquine and hydroxychloroquine), antivirals (lopinavir/ritonavir, ribavirin with or without interferon, oseltamivir, remdesivir, favipiravir, and darunavir), and treatments for complications (imatinib, tocilizumab, anakinra, immunoglobulins, corticosteroids, colchicine and low molecular weight heparins) are analyzed.
32783586 The goal of this study was to locate small molecules to be used against COVID19 instead of favipiravir. […] Favipiravir analogues were selected as drug candidates from the PubChem web tool. […] The RNA dependent RNA polymerase (RdRp) protein was selected as the target protein as favipiravir inhibits this protein in the human body. […] Then, the inhibition properties of selected drug candidates and favipiravir were examined in detail against SARS-CoV-2 RdRp proteins. […] It was found that 2-oxo-1H-pyrazine-3-carboxamide performed better than favipiravir in the results of molecular docking, molecular mechanics Poisson-Boltzmann surface area (MM-PSBA) calculations, and ADME analyses.
32786685 The drug repurposing study revealed the high potential of noscapine and proximal binding to the Mpro enzyme in a comparative binding pattern analyzed with chloroquine, ribavirin, and favipiravir.
32787752 Furthermore, ribavirin may also be a potential treatment against CHIKV; sofosbuvir against ZIKV; celgosivir against DENV, and favipiravir against EBOV and MARV, representing new hopes against these pathogens.
32801640 Some potential drugs have shown antiviral effects on SARS-CoV-2 infections, such as chloroquine, hydroxychloroquine, favipiravir, lopinavir/ritonavir, arbidol, interferon alpha, and remedsivir.
32817689 The five most frequently tested uni-modal interventions were: chloroquine/hydroxychloroquine (113 trials with 199,841 participants); convalescent plasma (64 trials with 11,840 participants); stem cells (51 trials with 3,370 participants); tocilizumab (19 trials with 4,139 participants) and favipiravir (19 trials with 3,210 participants).
32820005 No significant anti-SARS-CoV-2 activity was found for several compounds reportedly active against SARS-CoV-2 such as lopinavir, nelfinavir, nitazoxanide, favipiravir, and hydroxychroloquine.
32827400 Repurposing of drugs from different pharmacological groups including antivirals like remdesivir, lopinavir, ritonavir, arbidol, oseltamivir, penciclovir, favipiravir, ganciclovir, and ribavirin; other antibiotics like azithromycin, ivermectin, eravacycline, valrubicin, streptomycin, nitazoxanide, teicoplanin, caspofungin, and colistin; and other agents like hydroxychloroquine, chloroquine, tocilizumab, camostat, nafamostat, carfilzomib, interferon, aprepitant, and dexamethasone can be considered for COVID-19 therapy.
32834770 There is no experimental information about the tautomerism of Favipiravir (T-705).
32836314 The routes of synthesis are considered, as well as the modifications of the promising modern antiviral drug favipiravir.
32838169 Medications assessed included lopinavir/ritonavir, arbidol, hydroxychloroquine, tocilizumab, favipiravir, heparin, and dexamethasone. […] Favipiravir showed quicker symptom improvement compared to lopinavir/ritonavir and arbidol. […] Favipiravir shows favorable results compared to other tested medications.
32838264 Other candidates including tocilizumab, other interleukin 6 inhibitors, umifenovir, and favipiravir have insufficient data on pregnancy outcomes.
32841640 A number of multi clinical studies have repurposed combined cocktail (remdesivir + chloroquine and favipiravir + chloroquine) to be effective against COVID-19. […] Deep structural analysis of target molecules exposed key binding residues and structural twists involved in binding with important pharmacophore features of existing drugs [(7-chloro-N-[5-(diethylamino)pentan-2-yl]quinolin-4-amine (chloroquine),N-[[4-(4-methylpiperazin-1-yl)phenyl]methyl]-1,2-oxazole-5-carboxamide N-[[4-(4-methylpiperazin-1-yl)phenyl]methyl]-1,2-oxazole-5-carboxamide) (SSAA09E2), 2-ethylbutyl (2S)-2-{[(S)-{[(2R,3S,4R,5R)-5-{4-aminopyrrolo[2,1-f][1,2,4]triazin-7-yl}-5-cyano-3 (remdesivir) and 6-Fluor-3-oxo-3,4-dihydro-2-pyrazincarboxamid (favipiravir)]. […] It is evident from this structural informatics study that combo of chloroquine + SSAA09E2 with remdesivir or favipiravir could significantly restrain the virus at the entry and replication stage.
32844821 The aim of this systematic review was to evaluate the role of favipiravir along with its safety and efficacy for the patients who are suffering from severe acute respiratory distress syndrome due to CoronaVirus-2 (SARS-CoV-2) as re-purposeful use. […] We searched PubMed, EMBASE for randomized controlled trials (RCTs), cilicaltrial.com for registered on going trails to evaluate the pros and cons of using favipiravir in COVID-19. […] The 2 completed RCTs showed significantly better treatment effects on disease progression, viral clearance, improved the latency to relief for pyrexia and cough on favipiravir treated patients. […] Adverse effects caused Favipiravir are mild and manageable. […] Although 9 more RCTs and cohort studies are supposed to be completed by this time that may unveil some evidence for use of anti-RNA-viral drug favipiravir against influenza or Ebola to re-purposing against COVID-19 as adopted in different treatment guidelines.
32845145 Among these, the clinical efficacies of some accessible drugs such as remdesivir (RDV) and favipiravir (FPV) for COVID-19 are emphatically summarized.
32848446 Antiviral medication (lopinavir, darunavir, favipiravir, remdesivir, ribavirin, oseltamivir, tocilizumab, and umifenovir), ACE inhibitors, interferon-α2b, co-therapy with azithromycin, inhaling iNO, and oxygen therapy can be used for treatment.
32849448 These drugs include the broad spectrum antivirals such as umifenovir, protease inhibitors such as lopinavir/ritonavir as well as the RNA-dependent RNA polymerase inhibitors, remdesivir, and favipiravir.
32849934 We conclude from the evidence generated so far that interferon combined with antivirals, remdesivir, umifenovir and favipiravir were mostly associated with better clinical outcomes.
32850016 Herein we present a 26-year-old woman with a twin pregnancy at 36 wk and one day gestation with confirmed COVID-19 who responded dramatically to convalescent plasma therapy (CPT) and Favipiravir.
32864162 In this review, we summarized the pharmacogenomic literature available for COVID-19 drug therapies including hydroxychloroquine, chloroquine, azithromycin, remdesivir, favipiravir, ribavirin, lopinavir/ritonavir, darunavir/cobicistat, interferon beta-1b, tocilizumab, ruxolitinib, baricitinib, and corticosteroids.
32865382 Targeted therapies were used in six patients (2.7%), with hydroxychloroquine being the most commonly used agent either alone (one patient) or in combination with favipiravir (five patients).
32868801 Chloroquine, hydroxychloroquine, ritonavir/lopinavir, and favipiravir are under trials for the treatment of this disease.
32868989 He received 30 mg prednisolone for five days with antiviral drug of favipiravir, and was successfully extubated on day five. […] Combination treatment of short-course systemic corticosteroid and favipiravir might improve the prognosis for critically ill COVID-19 pneumonia with COPD without negative influence on viral clearance or antibody production.
32869558 There was limited evidence for the effect of corticosteroids, other antiviral drugs like ribavirin, and favipiravir.
32879154 We report a COVID-19 patient with adult T-cell leukemia-lymphoma (ATL) who was treated using favipiravir. […] Considering severe immunosuppression caused by ATL, we initiated favipiravir therapy. […] SARS-CoV-2 PCR tests were negative on days 17 and 18 of favipiravir therapy, and the patient was discharged without residual disease on the final CT.
32881656 The most common under trial drugs for COVID-19 are Remdesivir, Favipiravir, Chloroquine and Hydroxychloroquine, Azithromycin along with adjunct drugs like Amantadine with some monoclonal antibodies.
32883116 We propose combination of mAbs with remdesivir and/or favipiravir in severe COVID-19 cases, such as septic shock, acute respiratory deficiency syndrome, and/or multiple organ failure.
32887670 They covered topics of chemoprophylaxis (including agents and Traditional Chinese Medicine (TCM) agents), diagnosis (including clinical manifestations, reverse transcription-polymerase chain reaction (RT-PCR), respiratory tract specimens, IgM and IgG antibody tests, chest computed tomography, chest x-ray, and CT features of asymptomatic infections), treatments (including lopinavir-ritonavir, umifenovir, favipiravir, interferon, remdesivir, combination of antiviral drugs, hydroxychloroquine/chloroquine, interleukin-6 inhibitors, interleukin-1 inhibitors, glucocorticoid, qingfei paidu decoction, lianhua qingwen granules/capsules, convalescent plasma, lung transplantation, invasive or noninvasive ventilation, and extracorporeal membrane oxygenation (ECMO)), and discharge management (including discharge criteria and management plan in patients whose RT-PCR retesting shows SARS-CoV-2 positive after discharge).
32888379 A thorough literature search was conducted to source information on the pharmacological properties of 5 drugs and 1 combination (azithromycin, chloroquine, favipiravir, hydroxychloroquine, remdesivir, and lopinavir/ritonavir) repurposed to treat COVID-19.
32889701 Number of drugs such as remdesivir, favipiravir, ribavirin, lopinavir, ritonavir, darunavir, arbidol, chloroquine, hydroxychloroquine, tocilizumab and interferons have shown inhibitory effects against the SARS-CoV2 in-vitro as well as in clinical conditions.
32893160 Here, we report the successful treatment of 11 cases of severe COVID-19 pneumonia with favipiravir and methylprednisolone. […] All were treated with favipiravir and methylprednisolone, and 10 of 11 patients responded well and required no further oxygen supplementation or ventilator management. […] This study shows the importance of the early-stage use of a combination of favipiravir and methylprednisolone in severe cases to achieve a favorable clinical outcome.
32895599 One of the drugs which has recently garnered much attention, especially in India, is an anti-viral drug originally designed for influenza, called favipiravir.
32900659 He was admitted to the hospital and started to receive oxygen and favipiravir.
32904710 The use of chloroquine, hydroxychloroquine, favipiravir, ivermectin, and colchicine might also be effective.
32908046 Although the patients with hematological disease received favipiravir more frequently than patients with other diseases (21 [52.5%] vs.
32908736 Despite administration of multiple antiviral drugs, including lopinavir/ritonavir, chloroquine, and favipiravir, the patient’s condition did not improve.
32926918 Based on early experience, different treatment such as anti-viral drugs (remdesivir, favipiravir, lopinavir/ritonavir), corticosteroids (methylprednisolone, dexamethasone) or convalescent plasma therapy are recommended in addition to supportive care and symptomatic therapy.
32940880 Favipiravir, an antiviral agent developed for treatment of influenza, is one candidate treatment for COVID-19, but suitable dosages for patients with renal insufficiency are unknown. […] Here we provide a first report on the efficacy of favipiravir in a patient with ESRD undergoing hemodialysis. […] Those antiviral agents were subsequently switched to favipiravir. […] Favipiravir may be an effective option for the treatment of COVID-19-infected patients with ESRD.
32942296 In this study, we use the ligand-protein docking program and molecular dynamic simulation to ab initio investigate the binding mechanism and inhibitory ability of seven clinically approved drugs (Chloroquine, Hydroxychloroquine, Remdesivir, Ritonavir, Beclabuvir, Indinavir and Favipiravir) and a recently designed α-ketoamide inhibitor (13b) at the molecular level.
32943628 We demonstrate here that Favipiravir predominantly exerts an antiviral effect through lethal mutagenesis. […] It possesses both unusually high nucleotide incorporation rates and high-error rates allowing facile insertion of Favipiravir into viral RNA, provoking C-to-U and G-to-A transitions in the already low cytosine content SARS-CoV-2 genome.
32958718 Favipiravir is an oral broad-spectrum inhibitor of viral RNA-dependent RNA polymerase that is approved for treatment of influenza in Japan. […] We conducted a prospective, randomized, open-label, multicenter trial of favipiravir for the treatment of COVID-19 at 25 hospitals across Japan. […] Patients were randomly assigned at a 1:1 ratio to early or late favipiravir therapy (the same regimen starting on day 6 instead of day 1). […] Favipiravir did not significantly improve viral clearance as measured by RT-PCR by day 6 but was associated with numerical reduction in time to defervescence.
32962867 Though drugs like remdesivir, favipiravir, and dexamethasone found beneficial for COVID-19 management, they have limitations clinically, and vaccine development takes a long time.
32963155 Despite favipiravir treatment, acute respiratory distress syndrome developed in a 45-year-old patient with COVID-19; thus, TCZ was initiated.
32965013 There are several potential medications available for COVID-19, such as Interferon α (IFN-α), Teicoplanin, Ribavirin, Galidesivir, Lopinavir/Ritonavir, Chloroquine phosphate, Arbidol, Velpatasvir, Favipiravir, Ledipasvir, Remdesivir, Sofosbuvir, Darunavir, Qingfei Paidu Decoction (QPD), and Imatinib.
32965016 We summarized antiviral drugs against SARS-CoV-2, such as remdesivir, hydroxychloroquine and favipiravir.
32965359 This study aims to evaluate changes in hematological parameters after the follow-up of patients who received treatment with favipiravir due to COVID-19 infections. […] Sixty-two cases receiving favipiravir treatment for at least five days due to COVID-19 infection were evaluated retrospectively. […] The mean age of the patients receiving treatment with favipiravir was 63.7±12.3 years. […] In the statistical analysis of the hematological parameters before and after treatment with favipiravir, WBC, PT-PTT-INR levels were found to be unaffected; the mean RBC was found to have decreased from 4.33 ± 0.58 M/uL to 4.16 ± 0.54 M/uL (p:0.003); the median hemoglobin level was found to have decreased from 12.3 g/dl to 11.9 g/dl (p:0.041); the hematocrit level decreased from 38.1% ± 4.8 to 36.9% ± 4.2 (p:0.026); the median neutrophil count decreased from 4.57 K/uL to 3.85 K/uL (p:0.001); the mean lymphocyte count increased from 1.22 ± 0.53 K/uL to 1.84 ± 1.19 K/uL (p:0.000); and the mean platelet count increased from 244.1 ± 85.1 K/uL to 281.9 ± 103.3 K/uL (p:0.005). […] We concluded that the pathological effect of treatment with favipiravir on the hematologic system was the suppression in the erythrocyte series, and there were no adverse effects in other hematologic parameters.
32967849 In this issue of the Journal, Doi and colleagues successfully treated patients with early COVID-19 with favipiravir, an oral polymerase inhibitor to rapidly and substantially clear SARS-CoV-2 from nasal secretions irrespective if it was started relatively early or later within the first week of infection. […] These data support the concept that favipiravir could be paired with at least one more off-target antiviral agent (doxycycline, azithromycin, ivermectin) followed by corticosteroids and antithrombotics to prevent COVID-19 hospitalization and death in those over age 50 an or those with one or more comorbidities.
32969369 There are ongoing clinical trials on potential drugs such as remdesivir, favipiravir, lopinavir/ritonavir, chloroquine, and hydroxychloroquine, corticosteroids tocilizumab, azithromycin, anakinra, etc. and other therapeutic modalities like convalescent plasma therapy.
32970259 A variety of drugs, such as remdesivir and favipiravir, are currently undergoing clinical trials to evaluate for the management of COVID-19.
32972430 Favipiravir (FVP) triphosphate, a purine nucleoside analog, inhibits that enzyme.
32992014 Favipiravir, an antiviral agent, is undergoing clinical trials for treating novel coronavirus disease 2019 (COVID-19). […] We report two cases of COVID-19 with favipiravir-induced fever. […] In both cases, pyrexia was observed following administration of favipiravir despite symptoms of COVID-19 improving. […] Once favipiravir was discontinued, the fever subsided in both patients. […] To our knowledge, this is the first report of favipiravir-induced fever.
32997322 Among all these drugs, we focus on the most promising drugs (such as favipiravir, tocilizumab, SARS-CoV-2 convalescent plasma, hydroxychloroquine, Lianhua Qingwen, interferon beta-1a, remdesivir, etc.) that have or will enter the final stage of human testing-phase III-IV clinical trials.
32998618 The inhibitory effect of all studied compounds was studied with compared to some proposed antiviral drugs which currently used in COVID-19 treatment such as chloroquine, hydroxychloroquine, azithromycin, remdesivir, baloxvir, lopinavir, and favipiravir.
33001051 Several clinical trials are ongoing with hydroxychloroquine, remdesivir, favipiravir, and low molecular weight heparins.
33002954 Recent clinical trials suggested remdesivir, IFN-β-1b and favipiravir have potential clinical and/or virological benefits on patients with COVID-19.
33014380 This review aims to collect and summarize a list of drugs used to treat COVID-19, including dexamethasone, chloroquine, hydroxychloroquine, lopinavir/ritonavir, favipiravir, remdesivir, tociluzimab, nitazoxanide and ivermectin.
33029696 The repurposed drugs like Chloroquine and Hydroxychloroquine, Tenofovir, Remdesivir, Ribavirin, Darunavir, Oseltamivir, Arbidol (Umifenovir), Favipiravir, Anakinra, and Baricitinib are already being used in clinical trials to treat the COVID-19 patients.
33031623 The therapeutic effect of two drugs that are regarded to show therapeutic potential [i.e., remdesivir (RDV) and favipiravir (FPV)] against COVID-19 are discussed based on the current published data.
33031797 So far, chloroquine, lopinavir, hydroxychloroquine, azithromycin, favipiravir, ribavirin, darunavir, remdesivir, and umifenovir have been tested in COVID-19 clinical trials. […] Hydroxychloroquine, chloroquine, and favipiravir, which were highly distributed to the lung, were reported to reduce viral loads in respiratory tract of COVID-19 patients.
33037151 Treatment of SARS-CoV-2-infected hamsters with a low dose of favipiravir or hydroxychloroquine with(out) azithromycin resulted in, respectively, a mild or no reduction in virus levels. […] However, high doses of favipiravir significantly reduced infectious virus titers in the lungs and markedly improved lung histopathology. […] Moreover, a high dose of favipiravir decreased virus transmission by direct contact, whereas hydroxychloroquine failed as prophylaxis. […] In contrast, the results with favipiravir demonstrate that an antiviral drug at nontoxic doses exhibits a marked protective effect against SARS-CoV-2 in a small animal model.
33041712 Though data are limited, antiviral therapies such as remdesivir, favipiravir, lopinavir/ritonavir, and other drugs like hydroxychloroquine/chloroquine have been used for severe COVID-19 cases, with remdesivir showing the greatest promise.
33041830 These include antivirals (remdesivir, lopinavir/ritonavir, umifenovir, and favipiravir), interferon, antimalarials (chloroquine/hydroxychloroquine), antiparasitic drugs (ivermectin and nitazoxanide), biologics (monoclonal antibodies and interleukin receptor antagonist), cellular therapies (mesenchymal stem cells and natural killer cells), convalescent plasma, and cytokine adsorber.
33042544 The combination therapy of Lopinavir/Ritonavir plus Favipiravir might be a treatment option for patients with COVID-19.
