## Abstract A simple and rapid reversed‐phase HPLC method for determination of rifaximin in rat serum and urine was developed. Separation of rifaximin from biological matrix was achieved by direct injection of rat serum and urine onto a restricted‐access medium, Supelco LC‐Hisep, a shielded hydroph
