🦶🧴🛡️ Clotrimazole 1%: Broad-Spectrum Antifungal Cream for Skin and Mucosal Infections
Clotrimazole 1% is a widely used topical antifungal medication that treats various fungal skin and mucosal infections caused by dermatophytes, yeasts, and molds. It belongs to the imidazole class of antifungal agents and is available in the form of cream, lotion, powder, or vaginal suppositories. It is highly effective in treating common fungal infections such as athlete’s foot (tinea pedis), ringworm (tinea corporis), jock itch (tinea cruris), vaginal candidiasis, and pityriasis versicolor.
🔬 Mechanism of Action
Clotrimazole works by inhibiting the synthesis of ergosterol, a vital component of the fungal cell membrane. Without ergosterol, the fungal cell membrane becomes compromised, leading to leakage of intracellular contents, cellular disruption, and ultimately fungal cell death.
Its fungistatic (growth-inhibiting) and fungicidal (fungus-killing) properties depend on the concentration and duration of treatment.
📌 Indications and Uses
Clotrimazole 1% is indicated for the treatment of:
-
Tinea pedis (athlete’s foot)
-
Tinea cruris (jock itch)
-

-
Cutaneous candidiasis (yeast infections of the skin)
-
Vaginal candidiasis (as vaginal cream or pessary)
