Mupi-B

Mupirocin (2% w/w) + Bromelain (5% w/w)
Price: ₹110 - ₹140 for 15g tube (Approx.)
Mfr: Sun Pharmaceutical Industries Ltd. | Form: Ointment

📋 Clinical Overview

A topical combination ointment containing the antibiotic Mupirocin and the proteolytic enzyme Bromelain. Mupirocin is a unique antibiotic derived from Pseudomonas fluorescens, effective against Gram-positive bacteria, particularly Staphylococcus aureus and Streptococcus pyogenes. Bromelain, extracted from pineapple stems, acts as a debriding agent, breaking down necrotic tissue and fibrinous exudate, enhancing wound penetration of the antibiotic and promoting granulation. This combination is specifically formulated for infected wounds, burns, and ulcers where necrotic tissue impedes healing.

💊 Dosage & Administration

Adult: Apply a small amount (a ribbon of approx. 1-2 cm) to the affected area three times daily (TDS). Cover with a sterile gauze dressing if needed.

Note: 1. Clean and dry the affected area gently with saline or antiseptic. 2. Apply a thin layer of ointment using a sterile applicator or gloved hand. 3. Rub in gently until absorbed. 4. May be covered with a sterile non-occlusive dressing. 5. Wash hands before and after application. Do not use occlusive dressings unless advised by a physician.

⚠️ Contraindications

  • Known hypersensitivity to Mupirocin, Bromelain, or any component of the ointment (e.g., polyethylene glycol base)
  • Use in or around the eyes

🔬 Mechanism of Action

Mupirocin inhibits bacterial protein synthesis by reversibly and specifically binding to bacterial isoleucyl-tRNA synthetase. This prevents the incorporation of isoleucine into protein chains, leading to bacteriostatic effects at low concentrations and bactericidal effects at high concentrations. Bromelain exerts a selective chemical debridement action by hydrolyzing peptide bonds in denatured proteins, collagen, and fibrin present in necrotic tissue and exudates. It reduces inflammation, edema, and improves microcirculation, thereby facilitating the penetration of Mupirocin into the infected tissue.

🤕 Side Effects

  • Local burning or stinging sensation (usually transient)
  • Itching (pruritus) at the application site
  • Localized erythema (redness)
  • Dryness of skin
