Usage
This combination medication is prescribed for mixed bacterial and fungal skin infections, particularly where inflammation is also present. It is effective against various dermatological conditions, including athlete’s foot, jock itch, ringworm, and specific types of eczema and dermatitis.
Pharmacological Classification: This is a combination product containing a fluoroquinolone antibiotic (ciprofloxacin), a corticosteroid (clobetasol), a nitroimidazole antibiotic (metronidazole), and an antifungal agent (terbinafine).
Mechanism of Action: Ciprofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, essential for bacterial DNA replication and repair. Metronidazole disrupts DNA synthesis and causes DNA strand breakage in anaerobic bacteria and protozoa. Terbinafine inhibits squalene epoxidase, a fungal enzyme crucial for cell wall synthesis. Clobetasol, a potent topical corticosteroid, exerts anti-inflammatory, antipruritic, and vasoconstrictive effects.
Alternate Names
There are no officially recognized alternate names for this specific four-drug combination. However, individual components may have various synonyms. It’s crucial to avoid confusing this combination with products containing different strengths or additional ingredients.
Brand Names: Several brand names exist for this combination, often varying by region and manufacturer (e.g., GENCIP, TECLOFINE).
How It Works
Pharmacodynamics: Ciprofloxacin and metronidazole exert bactericidal action, killing bacteria. Terbinafine is fungicidal, killing fungi. Clobetasol reduces inflammation and itching associated with skin infections.
Pharmacokinetics: The topical application limits systemic absorption of these drugs. However, some absorption can occur, especially with clobetasol. Ciprofloxacin is primarily excreted renally. Metronidazole is metabolized hepatically. Terbinafine undergoes hepatic metabolism and is excreted in urine and feces. Clobetasol is metabolized in the liver.
Mode of Action (Cellular/Molecular): Ciprofloxacin targets bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication and repair. Metronidazole forms cytotoxic metabolites that damage bacterial and protozoal DNA. Terbinafine inhibits squalene epoxidase, leading to ergosterol depletion and fungal cell death. Clobetasol binds to glucocorticoid receptors, affecting gene transcription and ultimately reducing inflammation.
Elimination Pathways: Primarily renal excretion for ciprofloxacin and hepatic metabolism and excretion for metronidazole, terbinafine, and clobetasol.
Dosage
Standard Dosage
Adults: Apply a thin layer to the affected skin area twice daily. The duration of treatment depends on the infection type and severity and should be determined by the physician.
Children: Use in children under 12 is generally not recommended due to limited safety and efficacy data. If used, careful monitoring for adverse events is essential.
Special Cases:
-
Elderly Patients: Caution is advised. Close monitoring of the application site is needed.
-
Patients with Renal Impairment: Use with caution, particularly for prolonged periods or large areas, due to the potential for increased systemic absorption of clobetasol. Monitor for systemic adverse events.
-
Patients with Hepatic Dysfunction: Monitor closely, as hepatic impairment may affect drug metabolism.
-
Patients with Comorbid Conditions: Caution should be exercised in patients with diabetes or adrenal gland disorders, as clobetasol can affect glucose metabolism and adrenal function.
Clinical Use Cases
This combination is not typically recommended for the specialized clinical scenarios you’ve listed (intubation, surgical procedures, mechanical ventilation, ICU use, emergency situations). These situations often involve systemic infections or require different treatment approaches.
Dosage Adjustments
Dosage adjustments should be made based on individual patient response, severity of infection, and the presence of any renal or hepatic impairment. A physician should determine the appropriate dosage and duration of therapy.
Side Effects
Common Side Effects
Dryness, itching, burning, redness, peeling, and stinging at the application site.
Rare but Serious Side Effects
Allergic reactions (rash, hives, swelling), skin atrophy, telangiectasia, hypopigmentation, hypertrichosis (with clobetasol). Rarely, tendon rupture can occur with ciprofloxacin (even with topical use).
Long-Term Effects
Prolonged or excessive use of clobetasol can lead to skin thinning, striae, and other cutaneous adverse effects.
Adverse Drug Reactions (ADR)
Severe allergic reactions, skin infections, Cushing’s syndrome (with prolonged or high-dose clobetasol use), peripheral neuropathy (with ciprofloxacin).
Contraindications
Hypersensitivity to any of the components. Viral skin infections (herpes simplex, varicella, etc.), tuberculosis or syphilis of the skin, rosacea, acne vulgaris. Use with caution in patients with pre-existing liver or kidney disease.
Drug Interactions
Ciprofloxacin may interact with warfarin, theophylline, tizanidine. Clobetasol can interact with other topical medications. Metronidazole can interact with alcohol, warfarin, and disulfiram. Terbinafine may interact with certain antidepressants (e.g., SSRIs) and beta-blockers. Monitor patients closely for any potential interactions.
Pregnancy and Breastfeeding
Use during pregnancy and breastfeeding is generally not recommended unless the potential benefits outweigh the risks to the fetus or infant. The safety of this specific combination in pregnancy and lactation hasn’t been fully established. Consult a specialist before prescribing to pregnant or breastfeeding women.

Popular Combinations
While this four-drug combination is itself a combined product, it is not generally combined further with other drugs. It’s crucial to avoid polypharmacy and ensure that all components are necessary for the specific infection.
Precautions
-
General Precautions: Screen for allergies, assess liver and kidney function in patients with pre-existing conditions.
-
Specific Populations: See above for pregnancy, breastfeeding, children, elderly.
-
Lifestyle Considerations: Advise patients to avoid excessive sun exposure to the treated area, as clobetasol can increase photosensitivity.
