Atypical Secondary or Symptomatic Thrombocytopenic Purpura Developing with the Use of Quinidine Sulfate
Quinidine sulfate, which has a very similar chemical structural formula to that of quinine bisulfate, may on a rare occasion be the etiologic causative agent of an atypical secondary or symptomatic thrombocytopenic purpura of serious degree. Fortunately, the withdrawal of the drug results in a rapid return to normal of the hematologic picture. A case report of such an occurrence is presented. Three additional case reports have been collected from the literature since 1941.
