Identification
Common NameImipenem
ClassSmall Molecule
DescriptionSemisynthetic thienamycin that has a wide spectrum of antibacterial activity against gram-negative and gram-positive aerobic and anaerobic bacteria, including many multiresistant strains. It is stable to beta-lactamases. Clinical studies have demonstrated high efficacy in the treatment of infections of various body systems. Its effectiveness is enhanced when it is administered in combination with cilastatin, a renal dipeptidase inhibitor.

Chemical Taxonomy
Description belongs to the class of organic compounds known as thienamycins. These are beta-lactam antibiotics that differ from penicillins in having the thiazolidine sulfur atom replaced by carbon, the sulfur then becoming the first atom in the side chain.

Toxicity Profile
Route of ExposureImipenem is not effectively absorbed from the gastrointestinal tract and therefore must be administered parenterally.
Mechanism of ToxicityImipenem acts as an antimicrobial through the inhibition of cell wall synthesis of various gram-positive and gram-negative bacteria. This inhibition of cell wall synthesis in gram-negative bateria is attained by binding to pencillin binding proteins (PBPs). In E. coli and selected strains of P. aeruginosa, imipenem has shown to have the highest affinity to PBP-2, PBP-1a, and PBP-1b. This preferential binding to PBP-2 and PBP-1b results in the direct conversion of the individual cell to a spheroblast, which leads to rapid cell lysis and death without filament formation.
MetabolismRenal. Half Life: 1 hour
