Meropenem Kabi (Meropenem Trihydrate)

Meropenem Kabi is a broad‑spectrum carbapenem used for serious bacterial infections affecting various organ systems.

• Complicated intra‑abdominal infections: provides bactericidal activity against mixed aerobic and anaerobic pathogens.
• Nosocomial pneumonia: treats hospital‑acquired lower respiratory tract infections caused by resistant Gram‑negative bacteria.
• Meningitis: penetrates the cerebrospinal fluid to eradicate causative organisms.
• Severe sepsis: offers rapid bacterial clearance in systemic infection.
• Complicated urinary tract infections: eliminates resistant uropathogens in the urinary tract.

• Meropenem inhibits bacterial cell wall synthesis by binding with high affinity to penicillin‑binding proteins (PBPs). This binding disrupts the final transpeptidation step of peptidoglycan cross‑linking, leading to weakened cell walls and osmotic lysis, resulting in rapid bactericidal activity against a wide range of Gram‑positive and Gram‑negative organisms.

Adverse reactions may occur with any intravenous antibiotic and should be monitored during therapy.

Common Side Effects

• Diarrhea: mild to moderate gastrointestinal upset.
• Nausea: occasional feeling of queasiness.
• Rash: transient skin erythema.
• Elevated liver enzymes: mild, reversible transaminase increase.

Serious or Rare Side Effects

• Anaphylaxis: severe hypersensitivity reaction requiring immediate medical attention.
• Seizures: especially in patients with renal impairment or CNS disorders.
• Clostridioides difficile colitis: antibiotic‑associated colitis presenting with watery diarrhea.

Use meropenem with caution in specific clinical situations and monitor relevant parameters.

• Renal impairment: adjust dose based on creatinine clearance.
• Hepatic dysfunction: monitor liver function tests during prolonged therapy.
• Pregnancy and lactation: assess risk‑benefit ratio before use.
• Concomitant nephrotoxic drugs: increase monitoring of renal function.
• Allergic history: verify no prior carbapenem or beta‑lactam hypersensitivity.
• Store at 2‑8°C: keep refrigerated, protect from light, do not freeze.

Meropenem may interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Valproic acid: may reduce serum valproate levels, risking seizure breakthrough.
• Probenecid: can increase meropenem plasma concentrations, raising toxicity risk.

Moderate Interactions (Monitor Closely)

• Aminoglycosides: combined nephrotoxicity; monitor renal function.
• Loop diuretics: potential additive ototoxicity; assess auditory function.
• Anticoagulants: may enhance anticoagulant effect; check coagulation parameters.
