Carbenicillin (Geocillin) is a broad-spectrum, parenterally-administered, semisynthetic and bactericidal antibiotic belonging to the carboxypenicillin subgroup of the penicillins. It is also orally bioavailable as the indanyl sodium salt. It was discovered by scientists at Beecham and marketed as Pyopen. It has Gram-negative coverage which includes Pseudomonas aeruginosa but limited Gram-positive coverage. The carboxypenicillins are susceptible to degradation by beta-lactamase enzymes, although they are more resistant than ampicillin to degradation. Carbenicillin is also more stable at lower pH than ampicillin.
