Phenoxymethylpenicillin

Phenoxymethylpenicillin, commonly known as penicillin V, is an antibiotic useful for the treatment of a number of bacterial infections. It is a penicillin that is orally active. It is less active than benzylpenicillin (penicillin G) against Gram-negative bacteria. Phenoxymethylpenicillin is more acid-stable than benzylpenicillin, which allows it to be given orally. It exerts a bactericidal action against penicillin-sensitive microorganisms during the stage of active multiplication. It acts by inhibiting the biosynthesis of cell-wall peptidoglycan. It is not active against beta-lactamase-producing bacteria, which include many strains of Staphylococci.
