Usage
Beclometasone + Chlorocresol + Gentamicin + Miconazole is a topical combination medication indicated for inflammatory skin conditions, such as eczema and dermatitis, that are also infected with bacteria and fungi.
Pharmacological Classification:
- Beclometasone: Corticosteroid (topical)
- Chlorocresol: Antiseptic and preservative
- Gentamicin: Aminoglycoside antibiotic
- Miconazole: Imidazole antifungal
Mechanism of Action: This combination targets the different components of infected skin inflammation. Beclometasone reduces inflammation and itching. Gentamicin combats bacterial infections. Miconazole eliminates fungal infections, and Chlorocresol acts as a preservative in the formulation.
Alternate Names
This combination is often referred to by its components: Beclometasone, Chlorocresol, Gentamicin, and Miconazole. It’s available under various brand names, depending on the manufacturer and region, such as Clofung GM, Cipderm, Megaspan, and HI Span.
How It Works
Pharmacodynamics:
- Beclometasone: Binds to glucocorticoid receptors, inhibiting inflammatory mediators and reducing vascular permeability. This leads to decreased redness, swelling, and itching.
- Gentamicin: Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, leading to bacterial cell death.
- Miconazole: Inhibits ergosterol synthesis, disrupting fungal cell membrane integrity and causing fungal cell death.
Pharmacokinetics:
- Beclometasone: Primarily topical action with minimal systemic absorption. Metabolized in the liver and excreted in the urine and bile.
- Gentamicin: Limited systemic absorption when applied topically to intact skin. Primarily excreted renally in unchanged form.
- Miconazole: Minimal systemic absorption when applied topically. Metabolized in the liver and excreted in the feces.
- Chlorocresol: Acts locally as a preservative; its pharmacokinetics are generally not clinically relevant in topical application.
Dosage
Standard Dosage
Adults: Apply a thin layer to the affected area twice daily for 2-6 weeks, depending on the severity and location of the infection. Continue for at least one week after symptoms resolve.
Children: Use with caution in children. Consult a pediatrician for appropriate dosing and duration. Avoid application to large areas or prolonged use.
Special Cases:
- Elderly Patients: Similar to adults, monitor for skin atrophy with prolonged use.
- Patients with Renal Impairment: Caution is advised due to potential gentamicin absorption. Monitor renal function.
- Patients with Hepatic Dysfunction: Use with caution due to limited data.
- Patients with Comorbid Conditions: No specific adjustments, but exercise caution in patients with diabetes due to the potential for beclometasone to affect glucose levels.
Clinical Use Cases
Dosage for these cases is consistent with the standard dosage. Avoid prolonged use and occlusion, particularly in situations where the risk of systemic absorption may be increased:
- Intubation
- Surgical Procedures
- Mechanical Ventilation
- Intensive Care Unit (ICU) Use
- Emergency Situations
Dosage Adjustments
Dosage should be individualized based on patient response and condition severity.
Side Effects
Common Side Effects:

Drug Interactions
- Neuromuscular blocking agents: May enhance neuromuscular blockade.
- Anticoagulants (e.g., warfarin): May increase bleeding risk.
- CYP3A4 inhibitors (e.g., itraconazole, ketoconazole, ritonavir): May increase the risk of systemic side effects from beclometasone.
- Other topical medications: Avoid co-administration on the same area unless specifically directed by a physician.
Pregnancy and Breastfeeding
- Pregnancy: Use only if the potential benefit outweighs the risk to the fetus. Limited data are available on safety during pregnancy.
- Breastfeeding: Exercise caution. The extent of excretion in breast milk is unknown. Avoid applying to the nipple area.
Drug Profile Summary
- Mechanism of Action: Combined anti-inflammatory, antibacterial, and antifungal effects.
- Side Effects: Local skin irritation, burning, itching, dryness, redness, atrophy, striae, telangiectasia, hypopigmentation, allergic contact dermatitis. Rare systemic side effects include ototoxicity (gentamicin), nephrotoxicity (gentamicin), and Cushing’s syndrome (beclometasone).
- Contraindications: Hypersensitivity, viral skin infections, tuberculosis, syphilis, rosacea, acne, perioral dermatitis.
- Drug Interactions: Neuromuscular blockers, anticoagulants, CYP3A4 inhibitors.
- Pregnancy & Breastfeeding: Use with caution; limited data available.
- Dosage: Apply thinly twice daily for 2-6 weeks.
- Monitoring Parameters: Monitor the skin for improvement or adverse reactions. Monitor renal function (if prolonged gentamicin exposure is anticipated).
Popular Combinations
This is already a combination product. Additional topical medications on the same area are generally not recommended unless specifically directed by a physician.
Precautions
- Avoid prolonged use, occlusion, and application to broken skin.
- Use with caution in children and the elderly.
- Do not apply to the eyes, nose, mouth, or vagina. If accidental contact occurs, rinse thoroughly with water.
FAQs (Frequently Asked Questions)
A: Apply a thin layer to the affected skin twice daily for 2-6 weeks. The duration depends on the severity and location of the infection. Treatment should continue for at least one week after symptoms disappear.
Q2: Can this combination be used for all types of skin infections?
A: No. It is not effective against viral skin infections, tuberculosis, syphilis, or fungal infections resistant to Miconazole.
Q3: What are the common side effects?
A: Common side effects include mild, local skin reactions such as burning, itching, irritation, dryness, and redness.
Q4: What should I do if the condition doesn’t improve?
A: Consult a doctor if symptoms do not improve or worsen after the recommended treatment period.
Q5: Can I use this cream on my face?
A: Use with caution on the face. Avoid prolonged use as it can cause skin thinning.
Q6: Is it safe to use this cream during pregnancy or breastfeeding?
A: Consult a doctor before using during pregnancy or breastfeeding. There’s limited safety data available.
Q7: Can I stop using the cream once the symptoms clear?
A: No, complete the full course of treatment prescribed by your doctor, even if symptoms improve earlier. This helps prevent recurrence.
Q8: Can I cover the treated area with a bandage?
A: Generally, avoid using occlusive dressings (airtight bandages) as they may increase the risk of systemic side effects.
Q9: Are there any drug interactions I should be aware of?
A: Inform your doctor about all other medications you are using, especially anticoagulants and certain antifungals.
Q10: What should I do if I miss a dose?
A: Apply the missed dose as soon as you remember, unless it’s almost time for your next dose. Do not double the dose.
