MEROSEARCH-1GM is a potent, broad-spectrum antibiotic containing 1 gram of meropenem, a carbapenem-class antibacterial agent. It is designed to combat a wide range of severe bacterial infections, particularly those caused by multidrug-resistant organisms. Administered intravenously, MEROSEARCH-1GM is typically used in hospital settings under the supervision of healthcare professionals.


Composition:

  • Active Ingredient: Meropenem 1g

  • Formulation: Sterile powder for solution, intended for intravenous infusion.


Therapeutic Indications:

MEROSEARCH-1GM is indicated for the treatment of various serious infections, including

  • Complicated Skin and Soft Tissue Infections: Effective against infections caused by susceptible strains of bacteria, including Staphylococcus aureus and Streptococcus species.

  • Complicated Intra-Abdominal Infections: Such as peritonitis and appendicitis, often caused by E. coli, Klebsiella pneumoniae, and Bacteroides fragilis.

  • Bacterial Meningitis: Particularly in pediatric patients aged 3 months and older, target pathogens like Neisseria meningitidis and Streptococcus pneumoniae.

  • Community-Acquired Pneumonia: Including cases caused by multidrug-resistant organisms.

  • Febrile Neutropenia: As empirical therapy in immunocompromised patients.


Mechanism of Action:

Meropenem exerts its bactericidal effect by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, which is essential for cell wall integrity. This leads to cell lysis and death of the bacteria. Meropenem is stable against most beta-lactamases, including extended-spectrum beta-lactamases (ESBLs), making it effective against a broad range of pathogens.


Dosage and Administration:

  • Adults: Typically, 500 mg to 1 g is administered intravenously every 8 hours, depending on the severity and type of infection.

  • Pediatric Patients (≥3 months): Dosage is weight-based, commonly 20–40 mg/kg every 8 hours.

  • Administration: The powder should be reconstituted with an appropriate diluent and infused over 15 to 30 minutes.

  • Renal Impairment: Dose adjustment is necessary for patients with reduced kidney function.


Precautions and Warnings:

  • Allergic Reactions: Use with caution in patients with a history of hypersensitivity to beta-lactam antibiotics.

  • Seizure Risk: High doses may increase the risk of seizures, especially in patients with central nervous system disorders.

  • Superinfection: Prolonged use may result in overgrowth of non-susceptible organisms, including fungi.

  • Drug Interactions: Concomitant use with valproic acid may reduce serum levels of valproic acid, increasing seizure risk.


Possible Side Effects:

Common side effects include:

  • Nausea and vomiting

  • Diarrhea

  • Headache

  • Rash or pruritus

  • Injection site inflammation

Serious adverse effects are rare but may include severe allergic reactions, seizures, and Clostridioides difficile-associated diarrhea.


Storage:

  • Store the unopened vial at controlled room temperature (20°C to 25°C).

  • Reconstituted solutions should be used promptly or stored under recommended conditions as per the manufacturer's guidelines.


Conclusion:

MEROSEARCH-1GM (Meropenem 1g) is a critical antibiotic for treating severe and life-threatening bacterial infections, especially those caused by resistant strains. Its broad-spectrum activity and stability against beta-lactamases make it a valuable option in the antimicrobial arsenal. Administration should be under strict medical supervision, with appropriate monitoring for efficacy and potential adverse effects.
