How does the medication work ?
Cilastatin/Imipenem is carbapenem beta-lactam antibiotic with a broad spectrum of antibacterial activity. It exerts potent bactericidal action. Imipenem is the first representative of a new class of beta-lactam antibiotics - carbapenems. This class of antibiotics is characterized by a broad spectrum of bactericidal activity compared with other beta-lactam antibiotics.
