'Imipenem/cilastatin (marketed as Primaxin in the USA and as Tinaxin in India) is a broad spectrum beta-lactam antibiotic containing equal quantities of imipenem and cilastatin. It is related to the penicillin/cephalosporin family of antibiotics but is classified as belonging to the carbapenem class.

Mechanism

It has the ability to kill a wide variety of bacteria. It works by interfering with their ability to form cell walls, and therefore the bacteria break up and die.

• Imipenem, the active antibiotic agent, is rapidly degraded by the renal enzyme dehydropeptidase if administered alone (making it less effective); the metabolites can cause kidney damage.
• Administration. Primaxin FDA label, Food and Drug Administration. Oct 2006.</ref> It may be less likely to cause an allergic reaction in people who have had an allergic reaction to a penicillin in the past. It is particularly effective against Enterobacter species.
