Meticilina

Meticilina Uses, Dosage, Side Effects, Food Interaction and all others data.

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.

Meticilina (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.

Uses

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.

How Meticilina works

Similar to other beta-lactam antimicrobials, meticillin blocks synthesis of the bacterial cell wall. Meticilina stops cross-linkage between the peptidoglycan polymer chains, which make up a large portion of gram-positive bacterial cell walls. It does this by binding to and competitively inhibiting the transpeptidase enzyme used by bacteria to cross-link the peptide (D-alanyl-alanine) used in peptidogylcan synthesis.
