Better Known as: Flumadine
- Marketed By: Forest Labs
- Major Indication: Influenza Infection
- Drug Class: M2 Proton Channel Inhibitor
- Date of FDA Approval (Patent Expiration): 1993 (2001)
- 1994 Sales: N/A
- Importance: One of the the first treatments for Influenza Infections. Since 1994, nearly 100% of influenza viruses had developed resistance to rimantadine, and it is no longer recommended as a treatment for the flu.
- The following is a list of Pharmacokinetic Parameters. See: Pharmaceutical Drugs for more information
