Imipenem is a broad spectrum antibiotic used for treating a variety of bacteria causing diseases in humans. It is classified as a carbapenem. The broad spectrum comes from it being effective against aerobic and anaerobic gram positive and negative bacteria. The use of this antibiotic is restricted to avoid resistance by bacteria. It is known as a beta Lactam antibiotic as like other similar antibiotics it works by inhibiting bacterial cell wall synthesis.
Imipenem is a drug prescribed in combination with Cilastatin, a dehydropeptidase inhibitor to treat various bacterial infections. While it is the Imipenem that acts as an antibiotic and is lethal for many strains of bacteria, it gets more effective with the Cilastatin. Imipenem can be less effective on its own as it gets degraded quickly in the kidneys, but when it is clubbed with Cilastatin in equal proportions it reduces the production of dehydropeptidase. This is where Imipenem is more effective and can help the action of Imipenem for a longer duration.
Imipenem and Cilastatin are together sold under the trade name of Primaxin, Tienam and Zienam by Merck and Co. It is also marketed by an Indian Company under the trade name of Cilanem.

The treatment duration and strength depends on how your condition is and how you are responding to the medicine, so it is important to keep all appointments with your doctor or healthcare provider.
