Lenampicillin is a prodrug of ampicillin that inhibits bacterial penicillin binding proteins (transpeptidase) and thus is effective against a wide range of bacterial infections. The drug was developed and marketed in Japan (Takacillin, Varacillin), however its current marketing status is unknown and supposed to be discontinued.
