What is the difference between imipenem and meropenem?
Abstract Data synthesis: Imipenem, the first carbapenem, was first marketed in 1987; meropenem was introduced to the market in 1996. In general, imipenem is more active against Gram-positive cocci while meropenem is more active against Gram-negative bacilli. The agents display similar pharmacokinetics.
What is the action of imipenem?
Imipenem 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 penicillin-binding proteins (PBPs).
Can imipenem be given alone?
Imipenem is indicated for the treatment of severe infections due to multiresistant organisms. Alone, or in combination with an aminoglycoside, it can be used for serious mixed infections including pulmonary, intraabdominal, and soft-tissue infections. It is generally well tolerated.
What are the plasma levels of imipenem I.V.?
Intravenous infusion of PRIMAXIN I.V. over 20 minutes results in peak plasma levels of imipenem antimicrobial activity that range from 14 to 24 µg/mL for the 250 mg dose, from 21 to 58 µg/mL for the 500 mg dose, and from 41 to 83 µg/mL for the 1000 mg dose.
