Challenges and Restraints

Despite significant progress, the antiviral drugs market faces various hurdles:

1. Viral Resistance

The ability of viruses to mutate and develop resistance to existing drugs remains a major concern, necessitating the continuous development of new antiviral classes.

2. High R&D Costs and Regulatory Hurdles

Developing antivirals is expensive and time-consuming. Rigorous clinical trials, regulatory approvals, and post-marketing surveillance add to costs and delay launches.
