Description

Azlocillin is a semisynthetic penicillin with broad spectrum of anti-bacterial action. The drug is effective against gram-negative and gram-positive infections and acts by inhibition of penicillin-binding protein (PBP)-dependent bacterial cell wall synthesis. Azlocillin was marketed in the USA under the name Azlin (sodium salt), however, its approval was discontinued.

Sample Use Guides

In Vivo Use Guide

Gram-negative infections: 2 to 5 grams every 8 hours IV. Serious infections: 225 to 300 mg/kg/day IV in 4 to 6 divided doses (usual IV doses 3g q4h or 4g q6h) (up to 18 g/day).

Route of Administration: Intravenous

In Vitro Use Guide

In vitro activity of Azlocillin against different bacterial strains was determined. MIC50 values were 2 ugml (Enterococcus), 8 ug/ml (E. coli), 16 ug/ml (Enterobacter spp.), 64 ug/ml (Klebsiella spp.), 4 ug/ml (P. mirabilis), 16 ug/ml (P. aeruginosa, gentamicin susceptible)).
