Abstract
A 43 year old man with HIV and HCV infection and liver cirrhosis developed fatal lactic acidosis within five days from starting nifedipine for arterial hypertension. Multiple drug interactions, current and accumulated drug toxicities and the reduced liver function, might in combination have led to the acute lactic acidosis.
