Appropriate initial treatment for plaque psoriasis would be:

Topical anthralin (Dritho-Creme) used once a week

Topical pimecrolimus (Elidel) used twice a day.

Wet soaks with aluminum acetate (Burow's) solution used as needed

Topical triamcinolone 0.1% (Kenalog) used as "pulse" therapy (2-4 weeks at a time)
