Amphastar Pharmaceuticals
How has Amphastar Pharmaceuticals shifted its market after BAQSIMI?
Amphastar’s 2023 BAQSIMI acquisition and 2025 scale-up transformed it from a niche generic injectables maker into a branded metabolic and emergency-medicine contender, attracting higher-margin diabetic patients and new healthcare channels.
Customer demographics now include insulin-dependent adults, caregivers, endocrinologists, hospital formulary managers, and specialty clinics, with growing retail and international demand driven by differentiated nasal glucagon adoption.
