Pipemidic acid trihydrate, a derivative of Piromidic acid, is an antibacterial agent. Pipemidic acid trihydrate inhibits DNA gyrase. Pipemidic acid trihydrate is active against gram-negative bacteria including Pseudomonas aeruginosa as well as some gram-positive bacteria. Pipemidic acid trihydrate can be used for the research of intestinal, urinary, and biliary tract infections[1][2].
