• A questionnaire that was mailed to 510 randomly selected dermatologists in the United States surveyed their use of three systemic chemotherapeutic agents for the treatment of psoriasis during the two-year period of 1973 to 1974. Methotrexate was used by 52% of the surveyed dermatologists, while hydroxyurea and azaribine were used by 10% and 2%, respectively. Seventy-five percent of the dermatologists who used methotrexate treated ten or fewer psoriatic patients with this drug. Multiple dose therapy with methotrexate divided over a period of 36 hours each week was the preferred schedule of 66% of the dermatologists. Liver biopsy specimens and creatinine clearance tests were obtained for only 17% and 35% of patients, respectively, prior to initiating methotrexate therapy. The estimated number of dermatologisttreated psoriatics nationwide receiving methotrexate is 25,000.
