Clotrimazole IS the Active Ingredient
Clotrimazole is not a brand name—it is itself the active pharmaceutical ingredient. The question appears to contain a misunderstanding about pharmaceutical nomenclature. Clotrimazole is a synthetic imidazole derivative antifungal compound that serves as the active drug substance in various topical formulations 1, 2.
Chemical Identity and Formulation
Clotrimazole is the actual antifungal agent, not a product containing another active ingredient. When formulated into medications, clotrimazole is combined with inactive ingredients (excipients) such as:
- Benzyl alcohol
- Cetostearyl alcohol
- Cetyl esters wax
- 2-octyldodecanol
- Polysorbate-60
- Purified water
- Sorbitan monostearate 1
These inactive ingredients serve as the vehicle or base for delivering the clotrimazole, but clotrimazole itself remains the therapeutically active component.
Mechanism and Clinical Use
Clotrimazole functions as a broad-spectrum antifungal agent with primary activity against Candida species, Trichophyton species, Microsporum species, and Malassezia furfur 2, 3. The drug is available in multiple formulations including:
- 1% and 2% vaginal creams
- 100 mg and 500 mg vaginal tablets
- 1% topical cream and solution for cutaneous infections 4, 1
For vulvovaginal candidiasis, clotrimazole formulations achieve 80-90% cure rates when used as directed, with the 500 mg single-dose vaginal tablet demonstrating equivalent efficacy to multi-day lower-dose regimens 4, 5.
The compound has been in clinical use for over 45 years with well-established safety and efficacy profiles 5.
