Mupirocin ointment, a topical antibiotic, has gained significant attention in recent years due to its effectiveness in treating various bacterial skin infections. As a domain-specific expert with over a decade of experience in dermatology and infectious diseases, I will provide an in-depth analysis of mupirocin ointment, its mechanism of action, and its applications in clinical practice.
Understanding Mupirocin Ointment
Mupirocin ointment, also known as Bactroban, is a topical antibiotic medication used to treat bacterial skin infections such as impetigo, folliculitis, and cellulitis. It is available in various formulations, including ointment, cream, and nasal ointment. Mupirocin works by inhibiting bacterial protein synthesis, ultimately leading to the death of the bacterial cells.
Mechanism of Action
The mechanism of action of mupirocin involves the inhibition of isoleucyl-tRNA synthetase, an enzyme essential for bacterial protein synthesis. By binding to this enzyme, mupirocin prevents the incorporation of isoleucine into bacterial proteins, thereby disrupting protein synthesis and ultimately leading to bacterial cell death.

| Molecular Weight | 524.64 g/mol |
| Mechanism of Action | Inhibition of isoleucyl-tRNA synthetase |
Key Points
- Mupirocin ointment is a topical antibiotic used to treat bacterial skin infections.
- It works by inhibiting bacterial protein synthesis through the inhibition of isoleucyl-tRNA synthetase.
- Mupirocin is effective against a range of bacteria, including Staphylococcus aureus and Streptococcus pyogenes.
- It is available in various formulations, including ointment, cream, and nasal ointment.
- Mupirocin ointment is generally well-tolerated, with minimal systemic absorption.
Clinical Applications of Mupirocin Ointment
Mupirocin ointment has a range of clinical applications, including the treatment of:
Impetigo
Impetigo is a highly contagious bacterial skin infection, typically caused by Staphylococcus aureus or Streptococcus pyogenes. Mupirocin ointment has been shown to be effective in treating impetigo, with a significant reduction in symptoms and bacterial colonization.
Folliculitis
Folliculitis is an inflammation of the hair follicles, often caused by bacterial infections. Mupirocin ointment has been used successfully to treat folliculitis, reducing inflammation and bacterial colonization.
Cellulitis
Cellulitis is a bacterial skin infection that can cause redness, swelling, and warmth in the affected area. Mupirocin ointment has been used in conjunction with other treatments to manage cellulitis, particularly in cases where the infection is superficial.
