Pharmacodynamics

Ampexin Injection 500 mg/vial 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. Ampexin Injection 500 mg/vial has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of Ampexin Injection 500 mg/vial results from the inhibition of cell wall synthesis and is mediated through Ampexin Injection 500 mg/vial binding to penicillin binding proteins (PBPs). Ampexin Injection 500 mg/vial 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, Ampexin Injection 500 mg/vial 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 Ampexin Injection 500 mg/vial interferes with an autolysin inhibitor.

Route of Elimination

Ampexin Injection 500 mg/vial is excreted largely unchanged in the urine.

Food Interactions

  • Take on an empty stomach.
