Action
Description: Mechanism of Action: Clotrimazole inhibits ergosterol synthesis, which leads to structural and functional impairment of fungal cytoplasmic membrane. Hydrocortisone, a weak corticosteroid w/ both glucocorticoid and to a lesser extent mineralocorticoid activity, has antiphlogistic, antipruriginous, antiexudative and antiallergic effects. Pharmacokinetics: Absorption: Clotrimazole: Penetrates the epidermis w/ a little systemic absorption. Absorbed 3-10% of a dose (vag use). Hydrocortisone: Absorbed through the skin particularly in denuded areas. Distribution: Hydrocortisone: Plasma protein binding: >90%. Metabolism: Clotrimazole: Hepatically metabolised to inactive compounds. Hydrocortisone: Metabolised in the liver and tissues. Excretion: Clotrimazole: Via faeces and urine. Hydrocortisone: Via urine. Biological half-life: Approx 100 min.
D01AC - Imidazole and triazole derivatives ; Used in the topical treatment of fungal infection.
