Muderm

Muderm Uses, Dosage, Side Effects, Food Interaction and all others data.

Muderm inhibits protein synthesis of the bacteria by binding to isoleucyl transfer ribonucleic acid (RNA)-synthetase. It has bacteriostatic properties at Min inhibitory concentrations and bactericidal properties at the higher concentrations.

Muderm is reported to be active against susceptible aerobic gram-positive cocci, such as Staphylococcus aureus, Staphylococcus epidermidis, and other beta-hemolytic streptococciStreptococcus pyogenes. It mediates its antibacterial activity by inhibiting the bacterial protein synthesis and formation of bacterial proteins essential for survival. The minimum bactericidal concentration (MBC) against relevant pathogens is generally eight-fold to thirty-fold higher than the minimum inhibitory concentration (MIC). In one clinical study investigating the therapeutic effectiveness of topical mupirocin in impetigo, the therapeutic response rate was about 94 to 98% after one week following the end of therapy. In clinical studies of patients with primary and secondary skin infections, both elimination of the bacterial pathogen and clinical cure or improvement hav been demonstrated in over 90% of patients receiving topical mupirocin. Muderm resistance as high as 81% has been reported previously. Resistance to mupirocin, which occurs more frequently in methicillin-resistant than methicillin-susceptible staphylococci, may occur with the production of a modified isoleucyl-tRNA synthetase, or the acquisition of, by genetic transfer, a plasmid mediating a new isoleucyl-tRNA synthetase.

Uses

Muderm ointment or cream is used for the topical treatment of impetigo due to Staphylococcus aureus and Streptococcus pyogenes. It is also used for folliculitis and furunculosis.

Muderm is also used to associated treatment for these conditions: Impetigo, Impetigo caused by Staphylococcus aureus, Impetigo caused by streptococcus pyogenes, Secondary infection Skin infection, Staphylococcus aurea colonization of the nasal passage

How Muderm works

Muderm specifically and reversibly binds to bacterial isoleucyl transfer-RNA (tRNA) synthetase, which is an enzyme that promotes the conversion of isoleucine and tRNA to isoleucyl-tRNA. Inhibition of this enzyme subsequently leads to the inhibition of the bacterial protein and RNA synthesis. Muderm is bacteriostatic at lower concentrations but it exerts bactericidal effects with prolonged exposure, killing 90-99% of susceptible bacteria over a 24 hour period.

Dosage

Muderm dosage

Secondary skin infections:

  • Adult: As 2% cream: Apply to affected area three times daily for up to 10 days; re-evaluate after 3-5 days if no clinical response.
  • Child: ≥3 mth Same as adult dose.

Impetigo:

  • Adult: As 2% oint: Apply to affected area three times daily for 5-10 days; re-evaluate after 3-5 days if no clinical response.
  • Child: ≥2 mth Same as adult dose.

Side Effects

Burning, stinging, pruritus, pain, rash, erythema, dry skin, tenderness, cellulitis, pain or bleeding secondary to eczema, secondary wound infection, urticaria, swelling, increased exudates, contact dermatitis, furunculosis, exfoliative dermatitis. Rarely, systemic reactions (e.g. nausea, headache, dizziness, abdominal pain, ulcerative stomatitis, systemic allergic reactions).

Toxicity

LD50 and Nonclinical Toxicity

The oral LD50 value in rats is 5000 mg/kg. Studies evaluating the carcinogenic potential of mupirocin have not been performed. In various in vivo animal and in vitro bacterial assays, there was no evidence of genotoxicity caused by mupirocin. In reproduction studies using male and female rats, there were no signs of impaired fertility upon subcutaneous administration of mupirocin.

Use in special populations

Muderm was found to be excreted in human milk. As there is limited data on the use of topical mupirocin in pregnant women, the use of this drug in these patients should be undertaken with caution. Based on the findings in clinical trials, topical mupirocin was shown to be safe and effective in pediatric patients aged 2 months to 16 years.

Precaution

Muderm is not suitable for ophthalmic or intra-nasal use. When Muderm ointment is used on the face, care should be taken to avoid the eyes. In common with other polyethylene-based ointments, this drug should be used with caution if there is evidence of moderate or severe renal impairment. As with other antibacterial products, prolonged use may result in overgrowth of nonsusceptible organisms, including fung.

Interaction

Chloramphenicol may interfere with the antibacterial action of mupirocin in RNA synthesis.

Food Interaction

No interactions found.

Volume of Distribution

No information available.

Elimination Route

Systemic or percutaneous absorption of mupirocin following dermal application is expected to be minimal in adults and children. Occlusive dressings do not significantly enhance drug absorption, but damaged skin may allow enhanced penetration of the drug across the skin barrier.

Half Life

In healthy male volunteers, the elimination half-life of mupirocin was about 20 to 40 minutes following intravenous administration. The elimination half-life of monic acid was about 30 to 80 minutes.

Clearance

No information available.

Elimination Route

Any mupirocin reaching the systemic circulation is rapidly metabolized to form the inactive monic acid, which is eliminated by renal excretion. Following the application of Centany (mupirocin ointment),2% to a 400 cm2 area on the back of 23 healthy volunteers once daily for 7 days, the mean (range) cumulative urinary excretion of monic acid over 24 hrs following the last administration was 1.25% (0.2% to 3.0%) of the administered dose of mupirocin.

Pregnancy & Breastfeeding use

Use in Pregnancy: Because animal studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

Use in lactation: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Muderm ointment is administered to a nursing woman.

Contraindication

This drug is contraindicated in individuals with a history of sensitivity reactions to Muderm or any of the components of the preparation.

Special Warning

Pediatric Use: The safety and effectiveness of Muderm ointment have been established in the age range of 2 months to 16 years. Use of the ointment in these age groups is supported by evidence from adequate and well-controlled studies of Muderm in impetigo in pediatric patients.

Storage Condition

Store at or below 25° C. Do not freeze.
