Indications & Uses
Cispenam is indicated for:
Pharmacology
Imipenem + Cilastatin is a combined preparation. Imipenem is a penem antibacterial. Cilastatin sodium is a renal dehydropeptidase inhibitor, and it limits the breakdown of imipenem in the kidneys.
Imipenem kills bacteria by blocking the synthesis of their cell wall. It binds most strongly to penicillin binding proteins (PBPs) 1A, 1B, 2, 4, 5 and 6 of Escherichia coli, and to PBPs 1A, 1B, 2, 4 and 5 of Pseudomonas aeruginosa. The lethal effect is linked to binding to PBP 2 and PBP 1B.
Imipenem stays highly stable in the presence of beta-lactamases, both penicillinases and cephalosporinases, whether they are produced by Gram-negative or Gram-positive bacteria. It is also a potent inhibitor of betalactamases from certain Gram-negative bacteria that are naturally resistant to most beta-lactam antibacterials, for example Pseudomonas aeruginosa, Serratia spp. and Enterobacter spp.

Adults:
The adult dosage of Imipenem + Cilastatin should be based on suspected or confirmed pathogen susceptibility. For adult patients with normal renal function (creatinine clearance of greater than or equal to 90 mL/min), the recommended dosage regimens are 500 mg every 6 hours OR 1000 mg every 8 hours OR 1000 mg every 6 hours. The dose must be reduced for a patient with a creatinine clearance of less than 90 mL/min. Patients with creatinine clearances of less than 15 mL/min should not receive this combination unless hemodialysis is instituted within 48 hours. Reconstitute the vial with an appropriate diluent, then dilute the reconstituted suspension with an appropriate infusion solution before giving it by intravenous infusion.
The recommended pediatric dosage for non-CNS infections depends on age. For children greater than or equal to 3 months of age, it is 15 to 25 mg/kg every 6 hours. For those less than or equal to 3 months of age (greater than or equal to 1,500 g body weight), the dosage is 25 mg/kg every 6 hours at 4 weeks to 3 months of age, 25 mg/kg every 8 hours at 1 to 4 weeks of age, and 25 mg/kg every 12 hours at less than 1 week of age.

Hypersensitivity reactions Serious and sometimes fatal hypersensitivity (anaphylactic) reactions have been reported in patients treated with beta-lactams. If an allergic reaction to Imipenem + Cilastatin occurs, stop the medicine immediately. Seizure potential Seizures and other CNS adverse reactions, such as confusional states and myoclonic activity, have been reported during treatment with Imipenem + Cilastatin. If focal tremors, myoclonus or seizures occur, the patient should be evaluated neurologically and started on anticonvulsant therapy if this has not already been done. The dose of Imipenem + Cilastatin should also be re-examined, to decide whether it should be reduced or the antibacterial drug stopped.
