Market Overview
Dual oral antivirals are designed to target viral replication using complementary mechanisms of action while maintaining ease of administration. By combining two antiviral agents into a single oral formulation, these therapies help reduce dosing complexity, improve patient adherence, and lower the risk of resistance development. This approach is particularly valuable in chronic conditions where lifelong or long-term treatment is required.
Fixed-dose combination therapies dominate the market due to their convenience and strong clinical acceptance. They support consistent pharmacokinetic exposure and simplify treatment protocols for both patients and healthcare providers.
