Carbenicillin is an antibiotic belonging to the carboxypenicillin subgroup of the penicillins. It has gram-negative coverage which includes Pseudomonas aeruginosa but limited gram-positive coverage. The carboxypenicillins are susceptible to degradation by beta-lactamase enzymes.

Additional recommended knowledge

The antibiotic is very soluble in water and is acid-labile. Aqueous solutions are short-lived. Working concentration in the lab: up to 100 µg per ml.

It is a semi-synthetic analogue of the naturally occurring penicillin. Although much more expensive than ampicillin, it is much more stable.
