The Effectiveness and Safety of Favipiravir in COVID-19 Hospitalized Patients in Bali, Indonesia
et al., Kesmas: National Public Health Journal, doi:10.21109/kesmas.v16i4.5433, Nov 2021
Retrospective 192 hospitalized patients in Indonesia, 96 patients treated with favipiravir, showing improved recovery with treatment. Only the abstract is currently available.
Potential risks of favipiravir include kidney injury1-3, liver injury2-4, and mutagenicity, carcinogenicity, teratogenicity, embryotoxicity, and the creation of dangerous variants5-11.
This study is excluded in the after exclusion results of meta

"abstract": "<jats:p>COVID-19 is a major public health problem, with still questionable specific cure. Favipiravir is a COVID-19 antiviral that is potentially a therapy for COVID-19. This study aimed to analyze its effectivity and safety in moderate to critical hospitalized patients. This study was a retrospective cohort in a tertiary referral hospital in Denpasar City, Bali Province, Indonesia, from August 2020 to January 2021. There was a total of 192 patients; 96 in the favipiravir group and 96in the non-favipiravir group (remdesivir/oseltamivir). Effectivity was measured by assessing the clinical condition at the end of the isolation period of 14 days. The favipiravir group showed better clinical conditions than the non-favipiravir group (79.2% vs. 56.3%; adjusted RR = 2.196; 95% CI = 1.084 – 4.451; p-value= 0.029), seen from being free of fever and respiratory problems. Stratification analysis demonstrated that the clinical improvement was significantly differentin the severe/critical group in favor of favipiravir (RR = 1.573; 95% CI = 1.139-2.172). The most common non-serious adverse events (AE) found in the use offavipiravir were gastrointestinal disturbances (12.5%). In brief, favipiravir is effective in severe/critical cases, and less serious AE were found in its use. Appropriate treatment is expected to help in reducing the public health burden.</jats:p>",
