Brief Summary

Azvudine(FNC)，a nucleoside reverse transcriptase inhibitor, make itself a better candidate to be co-formulated in other anti-HIV therapies, thus to improve patient's compliance. FNC is a broad-spectrum RNA virus inhibitor that inhibits the novel coronavirus RNA-dependent RNA polymerase (RdRp).

This is a clinical study to evaluate the Interactions between Azvudine Tablets (FNC) and Rifampicin Capsules (RIF) in healthy subjects. This is a single-center, randomized, open-label, three-cycles, three-treatment crossover clinical trial. Subjects was administered orally for 7 consecutive days each cycle, and the washout period between each cycle was 7 days. Biological sample collection and safety examination were performed.
