Usage
This combination is prescribed for inflammatory skin infections with bacterial and fungal components, such as:
- Infected eczema or dermatitis
- Secondarily infected psoriasis
- Intertrigo
- Infected contact dermatitis
- Ringworm infections with secondary bacterial infection
Pharmacological Classification:
- Corticosteroid (Clobetasol)
- Antibiotic (Gentamicin)
- Antifungal (Ketoconazole, Clioquinol)
Alternate Names
There is no universally recognized generic name for this five-component combination. It is most accurately identified by listing its individual components. Sometimes, Tolnaftate is included. Brand names vary depending on the manufacturer and region.
How It Works
Pharmacodynamics:
- Clobetasol: A potent corticosteroid that binds to glucocorticoid receptors, reducing inflammation, itching, and redness by suppressing the immune response and inhibiting the production of inflammatory mediators like prostaglandins.
- Gentamicin: An aminoglycoside antibiotic that inhibits bacterial protein synthesis, leading to bacterial cell death.
- Ketoconazole: An imidazole antifungal that disrupts fungal cell membrane synthesis by inhibiting ergosterol production.
- Clioquinol: A hydroxyquinoline antifungal and antibacterial agent that inhibits DNA synthesis in susceptible microorganisms.
Pharmacokinetics:
Topical application limits systemic absorption. However, some systemic absorption can occur, especially with prolonged use or application to large or broken skin areas.
- Clobetasol: Metabolized in the liver.
- Gentamicin: Primarily excreted renally.
- Ketoconazole: Metabolized in the liver and excreted in bile and feces.
- Clioquinol: Partially metabolized and excreted in urine and feces.
Dosage
Because this is a combination of potent medications, dosage needs to be individualized. The smallest amount should be used for the shortest duration possible. Always consult with a dermatologist or healthcare professional for proper diagnosis and a tailored treatment plan as there is no standard dosing information available for this specific five-ingredient combination in recognized sources. Dosing depends upon the diagnosis, severity of the symptoms, patient comorbidities, and response to therapy.
Standard Dosage
Adults:
A thin layer of the cream is typically applied to the affected area 1-2 times daily. Treatment duration should be as short as possible (typically not exceeding 2-4 weeks) to minimize the risk of side effects from the corticosteroid component (Clobetasol).
Children:
Use in children should be under strict medical supervision due to the potent corticosteroid component. Safety and efficacy in children have not been fully established.
Special Cases:
- Elderly Patients: Increased risk of skin thinning and other adverse effects from Clobetasol. Use with caution.
- Patients with Renal Impairment: Gentamicin can be nephrotoxic, and Clioquinol can be systemically absorbed. Monitor kidney function and consider alternatives. Dose adjustment based on renal function is crucial.
- Patients with Hepatic Dysfunction: Clobetasol and Ketoconazole are metabolized in the liver. Careful patient monitoring and dose adjustments may be necessary.
- Patients with Comorbid Conditions: Assess potential drug interactions and adjust treatment as necessary.
Clinical Use Cases
This combination cream is typically not indicated for use in settings like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations.
