Imipenem is a broad-spectrum antibiotic belonging to the class of carbapenems. It is effective against a wide range of bacteria, including both gram-positive and gram-negative organisms. Imipenem is often used to treat serious infections, particularly those caused by multidrug-resistant bacteria. This medication is typically administered intravenously and is often combined with another antibiotic, cilastatin, to prevent its breakdown in the kidneys. Imipenem is commonly used in hospital settings for infections such as pneumonia, urinary tract infections, and intra-abdominal infections.
