Action
Description: Clotrimazole inhibits ergosterol synthesis, which leads to structural and functional impairment of fungal cytoplasmic membrane.

Distribution: Hydrocortisone: Plasma protein binding: >90%.
Metabolism: Clotrimazole: Hepatically metabolised to inactive compounds. Hydrocortisone: Metabolised in the liver and tissues.
