Oxacillin sodium monohydrate (Methicillin) is an antibacterial agent and is a narrow spectrum beta-lactam antibiotic of the penicillin class.

Oxacillin Sodium is the sodium salt form of oxacillin, a semisynthetic penicillinase-resistant and acid-stable penicillin with an antimicrobial activity. 

Oxacillin binds to penicillin-binding proteins in the bacterial cell wall, thereby blocking the synthesis of peptidoglycan, a critical component of the bacterial cell wall. This leads to inhibition of cell growth and causes cell lysis.
