title: [Frequency of drug adverse reactions among hospitalized patients].
abstract: This article describes the frequency of adverse reactions to drugs in a sample of hospitalized patients in the internal medicine ward seen during a year's term. Of 61 medical charts, we found 8 patients with adverse reactions to drugs during their hospital stay and another 4 patients hospitalized due to adverse reactions to drugs. The majority of the adverse reactions were of moderate degree (75%) and were related to drugs of cardiovascular action (58%). The frequency of reactions in hospitalized patients (13%) is comparable with the results obtained from other hospitals. Yet, the real magnitude of the problem is probably greater since the source of information (hospital charts) the totality of the clinical manifestations are not registered.
