DETAILS

DrugBank - DB01603

• Drug Groups: approved
• Description: One of the penicillins which is resistant to penicillinase but susceptible to a penicillin-binding protein. It is inactivated by gastric acid so administered by injection. [PubChem]
• Indication: Used to treat infections caused by susceptible Gram-positive bacteria, particularly beta-lactamase-producing organisms such as Staphylococcus aureus that would otherwise be resistant to most penicillins.
• Pharmacology: Meticillin (INN, BAN) or methicillin (USAN) is a narrow spectrum beta-lactam antibiotic of the penicillin class. It is no longer clinically used. Its role in therapy has been largely replaced by flucloxacillin and dicloxacillin, however the term methicillin-resistant Staphylococcus aureus (MRSA) continues to be used to describe Staphylococcus aureus strains resistant to all penicillins.
• Affected Organisms: Enteric bacteria and other eubacteria
• Biotransformation: Hepatic (20-40%).
• Absorption: Not absorbed following oral administration.
• Half Life: 25-60 minutes
