Used primarily in the treatment of plaque psoriasis, this compound helps regulate skin cell growth and differentiation. It reduces the rapid buildup of skin cells that cause scaling and inflammation typical in psoriatic lesions. Commonly formulated in topical ointments or creams, it is applied directly to affected areas for localized action. Due to its favorable safety profile, it is often prescribed for long-term management, especially in mild to moderate cases. It may also be combined with corticosteroids to enhance efficacy and reduce irritation. Not intended for widespread use over large body surface areas due to potential effects on calcium metabolism.
