Amphastar is a specialty pharmaceutical company that is engaged in developing, manufacturing, marketing, and selling generic and proprietary injectable, intranasal and inhalation pharmaceutical products.


Most of the products we currently sell are used in hospital or urgent care clinical settings and are primarily sold through group purchasing organizations and drug wholesalers.


We are also currently engaged in the development of our own branded product candidates that build on our scientific expertise in developing generic products.


Utilizing our highly experienced professionals and proven ability to develop and manufacture technically difficult products often with significant barriers to the market and produce our own API that is not readily available, we currently have over 20 drug products in the market and a robust pipeline to achieve long-term sustained growth.
