Imipenem and cilastatin treat infections triggered by antibiotic resistant bacteria. In most cases, individuals are hospitalized and receive treatment intravenously. These two medicines help to reduce the risks caused by drug-resistant bacteria, which sometimes result from an individual taking antibiotics over an extended period, building resistance of the bacteria. They are also used when standard practices relating to antibiotics have failed to treat the condition.
Imipenem is a carbapenem (antibiotic) used to fight the bacteria. Cilastatin is a dehydropeptidase inhibitor, working to delay the breakdown of imipenem by the kidneys. The action allows imipenem to remain in the body longer, stopping new growth and destroying active bacteria.
