Calpsor C Lotion is a combination of two medicines: Calcipotriol and Clobetasol which treat psoriasis. Calcipotriol is a form of vitamin D. It works by reducing the overproduction of skin cells that may build up and form scales on the skin. Clobetasol is a steroid which blocks the production of certain chemical messengers (prostaglandins) that make the skin red, swollen and itchy.
