Clotrimazole BP

Whatsapp Order

Clotrimazole BP is a broad-spectrum antifungal agent belonging to the imidazole class. It appears as a white to off-white crystalline powder that is practically insoluble in water but soluble in organic solvents like ethanol and chloroform. Clotrimazole is widely used in pharmaceutical formulations for the treatment of fungal infections affecting the skin, mucous membranes, and nails. Its mechanism involves inhibition of ergosterol synthesis, a vital component of fungal cell membranes, leading to increased cell permeability and fungal cell death. BP2000 indicates compliance with British Pharmacopoeia standards ensuring high purity and consistent quality suitable for pharmaceutical applications.

Clotrimazole BP Uses

Primary Uses

Pharmaceuticals & Healthcare

  • Used extensively in topical formulations (creams, ointments, lotions) for treating superficial fungal infections such as athlete’s foot (tinea pedis), ringworm (tinea corporis), jock itch (tinea cruris), and candidiasis.

  • Incorporated in vaginal suppositories and creams for the treatment of vulvovaginal candidiasis.

  • Utilized in oral lozenges and troches for oropharyngeal candidiasis (thrush).

  • Active ingredient in medicated powders and sprays for fungal infections in intertriginous areas.

  • Sometimes formulated in nail lacquers for onychomycosis (fungal nail infections).

 

Secondary Uses 

Veterinary Medicine

  • Used topically in veterinary antifungal preparations for fungal infections in animals.

Cosmetics & Personal Care

  • Occasionally incorporated in antifungal deodorants and foot-care products to prevent fungal growth and odor.

Research & Development

  • Employed in laboratory research studying antifungal mechanisms and resistance patterns.

  • Used in development of new antifungal delivery systems such as nanoparticles and controlled-release formulations.
