Meropenem Strides Pharma Uk (Meropenem Trihydrate)

Meropenem is a broad‑spectrum carbapenem antibiotic used for serious infections caused by susceptible bacteria.

• Complicated intra‑abdominal infections: provides bacterial eradication and clinical cure in patients with mixed‑flora peritonitis.
• Complicated urinary tract infections: eliminates Gram‑negative and some Gram‑positive pathogens in renal and bladder infections.
• Hospital‑acquired pneumonia: achieves microbiological clearance in ventilated patients with resistant organisms.
• Septicemia: rapidly reduces bacterial load in bloodstream infections, improving survival outcomes.

• Meropenem inhibits bacterial cell wall synthesis by binding with high affinity to penicillin‑binding proteins. This binding blocks the transpeptidation step of peptidoglycan cross‑linking, leading to weakened cell walls, osmotic instability, and ultimately bacterial cell lysis and death. Its broad spectrum includes many Gram‑negative, Gram‑positive and anaerobic organisms.

Adverse reactions may occur with meropenem therapy and are categorized by frequency.

Common Side Effects

• Nausea: mild to moderate gastrointestinal discomfort.
• Vomiting: occasional emesis during treatment.
• Diarrhea: may be watery and self‑limiting.
• Rash: skin erythema or pruritus.
• Headache: transient cranial discomfort.
• Elevated liver enzymes: transient increase in ALT/AST.

Serious or Rare Side Effects

• Seizures: especially in patients with renal impairment or CNS disorders.
• Anaphylaxis: acute hypersensitivity with respiratory or circulatory collapse.
• Clostridioides difficile infection: severe colitis following disruption of gut flora.
• Severe neutropenia: marked reduction in neutrophil count.
• Renal toxicity: acute kidney injury in predisposed individuals.
• Hypersensitivity reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Meropenem should be used with caution in specific clinical situations.

• Renal impairment: adjust dose based on creatinine clearance to avoid accumulation.
• History of seizures: monitor neurologic status, as the drug can lower seizure threshold.
• Hypersensitivity: discontinue immediately if allergic reactions develop.
• Pregnancy and lactation: only use when potential benefit justifies potential risk to fetus or infant.
• Concomitant nephrotoxic drugs: increase monitoring of renal function.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Meropenem may interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

• Valproic acid: carbapenems reduce serum valproate levels, risking seizure breakthrough.
• Other carbapenems: concurrent use may increase toxicity without added benefit.

Moderate Interactions (Monitor Closely)

• Aminoglycosides: combined nephrotoxic potential warrants renal function monitoring.
• Loop diuretics: may enhance renal clearance, requiring dose reassessment.
• Probenecid: can decrease renal excretion of meropenem, raising plasma concentrations.
