Topical therapy remains the first-line treatment of plaque psoriasis. Various agents are available, and the effects should become apparent within the first 2-3 weeks of use. Clearing of scale is typically observed first, followed by flattening of treated plaques. It may take 6-8 weeks for erythema to be fully resolved.

Anthralin may be used for the treatment of plaque psoriasis, but only with the auxiliary agent salicylic acid, which provides chemical stability. Conversely, salicylic acid inactivates calcipotriene and should not be used with it.

For additional information, refer to the international treatment guidelines.
