MEROSEARCH-SB

MEROSEARCH-SB

MEROSEARCH-SB Injection is a combination antibiotic containing Meropenem and Sulbactam, used for the treatment of serious and complicated bacterial infections. It belongs to the carbapenem class of antibiotics and is particularly useful in hospital settings for managing severe infections caused by susceptible bacteria, including certain multidrug-resistant organisms. Meropenem works by inhibiting bacterial cell wall synthesis, while Sulbactam provides additional antibacterial activity and helps inhibit certain beta-lactamase enzymes. This medicine is administered intravenously under the supervision of qualified healthcare professionals.

Composition:

  • Active Ingredients: Meropenem 500 mg + Sulbactam 250 mg
  • Total Strength: 750 mg
  • Formulation: Sterile powder for solution for intravenous injection or infusion.

The 500 mg + 250 mg composition is listed for MEROSEARCH-SB 750 mg in a pharmaceutical product inventory. Please cross-check the manufacturer's vial label before publication.

Therapeutic Indications:

MEROSEARCH-SB Injection may be prescribed for the treatment of serious bacterial infections caused by susceptible organisms, including:

  • Severe Pneumonia: Helps treat complicated bacterial infections affecting the lungs and respiratory system.
  • Complicated Urinary Tract Infections: Used for serious bacterial infections affecting the urinary tract, including the kidneys and bladder.
  • Intra-Abdominal Infections: May be used to manage complicated infections within the abdominal cavity, including peritonitis.
  • Skin and Soft Tissue Infections: Helps treat serious bacterial infections affecting the skin and underlying tissues.
  • Bloodstream Infections: May be prescribed for severe bacterial infections involving the bloodstream, including sepsis.
  • Drug-Resistant Bacterial Infections: May be considered for certain difficult-to-treat infections, including those caused by susceptible strains of Acinetobacter baumannii, based on antibiotic susceptibility testing.

Mechanism of Action:

MEROSEARCH-SB Injection works through the combined antibacterial action of Meropenem and Sulbactam.

  • Meropenem: It is a broad-spectrum carbapenem antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This disrupts the formation of the bacterial cell wall, eventually leading to bacterial cell death.
  • Sulbactam: It is a beta-lactamase inhibitor that helps prevent certain bacterial enzymes from breaking down antibiotics. It also has intrinsic antibacterial activity against certain bacteria, particularly Acinetobacter baumannii.

Together, these ingredients provide complementary antibacterial activity against susceptible bacterial pathogens.

Dosage and Administration:

  • Dosage: The recommended dose depends on the type and severity of infection, patient's age, body weight, kidney function, and overall health condition.
  • Administration: Administered intravenously (IV) by a qualified healthcare professional in a hospital or clinical setting.
  • Frequency: The dosage and frequency of administration are determined by the treating physician based on the patient's clinical condition.
  • Treatment Duration: The complete prescribed course should be followed to ensure effective treatment.
  • Renal Impairment: Dose adjustment may be necessary in patients with reduced kidney function.

Precautions and Warnings:

  • Allergic Reactions: Avoid using this medicine if you have a known severe allergy to Meropenem, Sulbactam, penicillins, cephalosporins, or other beta-lactam antibiotics.
  • Kidney Disorders: Inform your doctor if you have kidney disease, as dosage adjustments may be required.
  • Seizure Risk: Use with caution in patients with a history of seizures or central nervous system disorders.
  • Gastrointestinal Disorders: Inform your doctor about any history of stomach or intestinal problems, particularly antibiotic-associated diarrhoea.
  • Drug Interactions: Inform your doctor about all medicines you are taking, especially valproic acid, probenecid, and other antibiotics.
  • Pregnancy and Breastfeeding: Consult your doctor before using this medicine during pregnancy or breastfeeding.
  • Elderly Patients: Special monitoring may be required in elderly patients, particularly those with impaired kidney function.
  • Antibiotic Resistance: Use this medicine only when prescribed and complete the recommended treatment course to help prevent antibiotic resistance.

Possible Side Effects:

Common and reported side effects associated with Meropenem and Sulbactam injections may include:

  • Diarrhoea or loose stools
  • Nausea and vomiting
  • Headache
  • Skin rash
  • Itching
  • Anaemia
  • Pain or discomfort at the injection site
  • Swelling or redness at the injection site
  • Inflammation of the veins (phlebitis)

Serious adverse reactions may include severe allergic reactions, seizures, and severe antibiotic-associated diarrhoea. Seek immediate medical attention if these symptoms occur.

Storage:

  • Store the unopened vial according to the manufacturer's recommended storage conditions.
  • Protect the medicine from excessive heat, moisture, and direct sunlight.
  • Reconstituted solutions should be used or stored according to the manufacturer's instructions.
  • Keep the injection out of reach of children.

Conclusion:

MEROSEARCH-SB Injection (Meropenem 500 mg + Sulbactam 250 mg) is a combination antibiotic used for managing serious and complicated bacterial infections caused by susceptible organisms. Its dual-action formulation combines bacterial cell wall inhibition with Sulbactam's beta-lactamase inhibition and intrinsic antibacterial activity. It may be particularly useful in selected difficult-to-treat infections, including certain Acinetobacter baumannii infections. Administration should be performed under strict medical supervision, with appropriate monitoring of kidney function, treatment response, and potential adverse effects.
