Rapid improvement of icterus and pruritus by the oral administration of colestimide in two cases of drug-induced hepatitis.

We report two cases of drug-induced hepatitis refractory to therapy of ursodeoxycholic acid and prednisolone, who were relieved of icterus and pruritus immediately by the oral administration of colestimide. Their liver dysfunction was not improved, by withdrawal of causative drugs or by treatment with prednisolone and ursodeoxycholic acid. Colestimide (3.0 g/day), a strong basic anion-exchange resin, was orally taken before breakfast and evening meal, leading to rapid and complete relief of icterus and pruritus. These cases suggested that colestimide would be useful for patients with cholestasis in drug-induced hepatitis, because this agent has few side effects and it is easy to take.
