Drug Type Insights

Locally Acting Antiviral Agents dominate the drug type segment and are expected to grow at a CAGR of 5.7% over the forecast period. These drugs, including novel agents such as baloxavir marboxil, directly target the virus, offering more rapid symptom relief and reduced viral replication. With rising concerns about the efficiency and safety of older antiviral drugs, adopting locally acting antivirals will likely increase significantly across Asia-Pacific. The segment’s growth is further fueled by the expanding availability of these drugs in urban and rural healthcare settings, thanks to improved distribution networks and government initiatives to increase access to essential medications.
