Vectical Ointment is a topical antipsoriatic called calcitrol. Sometimes, this medication may be referred to as “Silkis Ointment", and can be purchased as the brand choice in 3mcg!

Vectical Ointment is used to treat plaque psoriasis. Psoriasis is a long term skin disease where the skin cells have a much faster rate of growth and because of this, the surface of the skin will collect a buildup of cells. The buildup will form red, raised patches that are covered with silver-colored scales. Vectical Ointment is only used on mild to moderate cases of psoriasis; it should not be used to treat severe psoriasis.

Vectical Ointment (calcitrol ointment) is effective at treating mild to moderate psoriasis because calcitrol is a form of vitamin D and is able to decrease the rate of skin cell reproduction.
