[Acute interstitial nephritis caused by clozapine].

We are reporting a case of a 69 years old man developed acute renal failure due to interstitial nephritis during treatment with the drug clozapine, and that improve after to discontinuation of this drug. The clozapine is a new antipsychotic drug that may produce severes adverses reactions, like medullary toxicity. Recently 10 cases of clozapine-induced AIN have been reported. We want to associate to the cases publicated with a new case because it is a severe adverse reaction.
