Dovonex

Dovonex is a synthetic vitamin D-related compound used to treat psoriasis. It is marketed commercially as an ointment, cream, lotion, or solution and is available over-the-counter in some countries. Dovonex is also known as calcipotriene.

Uses

Dovonex is used to treat psoriasis, a condition characterized by the appearance of red, scaly patches on the surface of the skin. It can be used on the face, scalp, or body.

Mechanism of Action

Dovonex works by inhibiting the abnormal proliferation of skin cells associated with psoriasis. It does this by binding to the Vitamin D receptor (VDR), which is present in virtually all cells of the epidermis and considered essential for proper cell function. By binding to the VDR, calcipotriol blocks the activation of proteins called keratins, which are responsible for the abnormal proliferation of skin cells associated with psoriasis.

How long does it take to work?

Dovonex typically takes 3-4 weeks to show its full effect. After that, you should notice a significant reduction in the symptoms associated with psoriasis including scaling and redness.

Absorption, Route of Elimination, and Dosage

Dovonex is absorbed through the skin into the bloodstream. It is then rapidly eliminated from the body through the urine. The usual recommended dosage for treating psoriasis is to apply calcipotriol to the affected area twice daily. The amount that is to be applied varies depending on the severity of the condition.
