Methotrexate in psoriasis with and without leucovorin: effect of different dosage schedules on acute liver toxicity
Zachariae H, Bjerring P.
Studies on thirty-six psoriatics revealed no differences in acute liver toxicity of four different intermittent dosage schedules of methotrexate with or without addition of leucovorin, as judged by daily determinations of SGOT for one week. Three patients with psoriatic erythroderma receiving high-dosage methotrexate (100 mg i.v.) with leucovorin rescue responded extremely well to treatment and did not distinguish themselves from the other patients with regard to acute liver toxicity.
