AVANIR Pharmaceuticals is working to research and develop therapeutic products to treat chronic human diseases. In this section of the website, you will learn about the products that are already available in the marketplace, as well as our product candidates that are still in development. You will also learn about the developmental process from preclinical testing to approval. A look at our products and processes explains why AVANIR has become one of only a handful of Southern California biotech companies to successfully navigate the regulatory process and gain full marketing approval from the US Food and Drug Administration (FDA).
