United States Generic Drug Market Growth & Trends

Several key trends and drivers are fueling the expansion of the U.S. generic drug market:

• Chronic Disease Burden: A growing number of patients with chronic conditions like hypertension, diabetes, and depression is increasing long-term demand for generic alternatives.

• FDA Support for Faster Approvals: The U.S. FDA’s Drug Competition Action Plan (DCAP) streamlines the approval process for generics, especially those with limited competition.
