Mycophenolic Acid in the Treatment of Psoriasis

Abstract

• Thirty five patients with psoriasis (plaque type 26, guttate 3, pustular 4, and erythrodermic 2) were treated with oral mycophenolic acid for a period ranging from 52 to 104 weeks. The average followup was 89 weeks, and the dose schedule ranged from 2,400 to 7,200 mg daily. Excellent response was noted in 20 patients, good in 13 patients, and poor in 2. The most common clinical side effects were in the gastrointestinal tract, namely, diarrhea, nausea, abdominal cramps, and soft stools. A high incidence of herpes simplex, herpes zoster, and a flu-like syndrome was noted. Laboratory abnormalities consisted of mild blood hemoglobin reduction, one case of leukopenia (3,900 WBCs per cubic millimeter), two cases with thrombocytopenia and mild elevation of alkaline phosphatase. Mycophenolic acid appears as a promising drug for the treatment of severe psoriasis. (Arch Dermatol113:930-932, 1977)
