ampicillin
drug used in the treatment of various infections, including otitis media (middle ear infection), sinusitis, and acute bacterial cystitis. Ampicillin (or alpha-aminobenzylpenicillin) is a semisynthetic penicillin, one of the first such antibiotics developed. Similar in action to penicillin G but more effective against gram-negative bacteria, ampicillin is more stable in stomach acids and therefore may be given orally.
