Abstract
This study compared the pharmacokinetics and safety of favipiravir oral solution with those of tablet formulations, which were agents repurposed to treat nonsevere coronavirus disease 2019 in Thailand. In an open-label, single-dose, randomized, crossover study, 24 healthy subjects under fasting conditions were randomly assigned to a single dose of 200 mg of favipiravir, either as an oral solution of 200 mg/15 mL (test product) or a tablet (reference product), separated by a 7-day washout period. Fifteen plasma samples were collected over 12 hours after drug administration. Plasma favipiravir levels were quantified using in-house developed ultra-high-performance liquid chromatography-tandem mass spectrometry. The test/reference geometric mean ratio along with 90%CI for the maximum plasma concentration, area under the concentration-time curve (AUC) to the time of the last quantifiable concentration, and AUC after single-dose administration, extrapolated to infinity were 115.3% (90%CI, 107.7%-123.3%), 100.4% (90%CI, 96.9%-104.0%), and 100.4% (90%CI, 96.8%-104.2%), respectively. These results were within the predefined acceptance criteria for bioequivalence (80.0%-125.0%). No adverse events were observed in either group. The oral solution formulation could offer the advantage of easier swallowing in broader patient groups.
