[High-dose cepharanthin therapy of idiopathic thrombocytopenic purpura].

ABSTRACT

Clinical efficacy of oral high-dose cepharanthin (40-60 mg/day) was evaluated in nine patients with idiopathic thrombocytopenic purpura who were unable to discontinue the administration of adrenocorticosteroids or immunosuppressive drugs. Mean platelet counts significantly (p less than 0.05) rose from 4.5 +/- 0.9 x 10(4)/microliters to 8.9 +/- 4.2 x 10(4)/microliters without any side effects. Two to five months after the initiation of this therapy, 4 patients, including 3 who could discontinue adrenocorticosteroids, kept their platelet counts over 10 x 10(4)/microliters. It was suggested that the oral administration of cepharanthin could be a beneficial and safe strategy for ITP.
