Medical information for A-Flox Capsule 500 mg

Uses, dosage, side effects, and safety details below apply to A-Flox Capsule 500 mg (generic: Flucloxacillin Sodium). This is general information — consult a doctor before use.

Introduction

Antibiotic analog of cloxacillin.

Uses

Flucloxacillin is a narrow spectrum penicillin antibiotic that exerts specific activity against Gram positive organisms in skin and soft tissue infections, except those caused by methicillin resistant staphylococcus aureus (MRSA).

Used to treat bacterial infection by susceptible microorganisms.

Associated Conditions

  • Susceptible infections

Pharmacodynamics

Flucloxacillin is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The name "penicillin" can either refer to several variants of penicillin available, or to the group of antibiotics derived from the penicillins. Flucloxacillin has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of Flucloxacillin results from the inhibition of cell wall synthesis and is mediated through flucloxacillin binding to penicillin binding proteins (PBPs). Flucloxacillin is stable against hydrolysis by a variety of beta-lactamases, including penicillinases, and cephalosporinases and extended spectrum beta-lactamases.

Mechanism of Action

By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, flucloxacillin inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that flucloxacillin interferes with an autolysin inhibitor.

Absorption

Bioavailability is 50–70% following oral administration.

Half Life

0.75–1 hour
