🌿 What Is Mupirocin 2% (T-Bact Ointment)?
Topical antibiotics play a critical role in dermatology by delivering high local concentrations of drug to infected skin sites while minimizing systemic exposure. T-Bact Ointment contains 2 % mupirocin, a unique antibiotic that inhibits bacterial isoleucyl-tRNA synthetase, preventing protein synthesis in Gram-positive cocci such as Staphylococcus aureus and Streptococcus pyogenes.
Impetigo (non-bullous and bullous), a contagious superficial skin infection common in children, manifests as honey-colored crusts around the nose and mouth. Infected wounds, minor burns, and folliculitis (inflamed hair follicles) also benefit from topical therapy. By targeting local pathogens, T-Bact provides rapid bacterial clearance, reduced lesion size, and decreased transmission risk. Its semi-occlusive ointment base enhances skin penetration and maintains a moist environment conducive to wound healing.
For further details on mupirocin’s safety and efficacy, refer to the FDA label and the Drugs.com monograph. Additional guidance on impetigo management can be found at the NHS and the WHO essential medicines list.
🧬 Pharmacology & Mechanism of Action
| Attribute | Detail |
|---|---|
| Chemical Formula | C17H26N2O9S2 |
| Molecular Weight | 500.6 g/mol |
| Mode of Action | Inhibits bacterial isoleucyl-tRNA synthetase → halts protein synthesis |
| Spectrum of Activity | Primarily Gram-positive cocci (including MRSA), some Gram-negative bacteria |
| Resistance Risk | Low when used correctly, but resistance can develop with prolonged use |
Mupirocin’s unique mechanism avoids cross-resistance with other antibiotic classes. It is demonstrated to eradicate MRSA colonization when applied intranasally, although such off-label use requires physician supervision.
💡 Indications & Application Guidelines
| Condition | Regimen |
|---|---|
| Impetigo (Non-bullous & Bullous) | Apply T-Bact thinly to affected area 2–3 times daily for 5–7 days |
| Infected Minor Wounds (Furuncles, Folliculitis) | Gently clean lesion, then apply ointment twice daily until resolution (usually 3–5 days) |
| Nasal MRSA Eradication (Off-Label)** | Apply a pea-sized amount inside each nostril twice daily for 5 days (healthcare setting) |
Before applying, cleanse the area with mild soap and water, pat dry, and apply a thin layer of ointment. Do not occlude unless directed by a clinician. For nasal use, insert a small applicator or fingertip-wrapped gauze into each nostril to distribute the ointment.
⚠️ Warnings & Side Effects
Common (≤10 %):
- Local irritation: burning, stinging, itching
- Dryness or mild erythema at application site
Serious (Rare):
- Secondary fungal infections (Candida)
- Hypersensitivity reactions: rash, urticaria, anaphylaxis (rare)
- Systemic toxicity if large-area application or use on deep wounds
Discontinue T-Bact if severe local irritation or hypersensitivity occurs. Avoid prolonged use to minimize resistance. Do not apply near eyes, or ingest. In case of accidental contact with eyes, rinse thoroughly with water.
