Amphastar Pharmaceuticals wants to be a star in the niche drug firmament. The company makes specialty and branded generic drugs in injectable, topical, and inhalant forms. Using its proprietary delivery systems, the company focuses on drugs that are difficult to manufacture or can be improved with new delivery methods. Amphastar's 15 products include Amphadase (increases absorption and dispersion of injected drugs), Cortrosyn (tests for adrenal gland disorders), and Naloxone (reverses the effects of opioids like painkillers and other narcotics). It also manufactures the branded asthma drug Primatene Mist, which is sold over the counter, and has about a dozen generics in its pipeline. Amphastar was formed in 1996 and went public in 2014.
