Perfil de uso de anticoagulantes en pacientes hospitalizados, interacciones farmacológicas y reacciones adversas identificadas

The effects of anticoagulants are known as treatment or prophylaxis of thrombotic events, allowing to establish an individualized therapy according to their needs. A descriptive cross-sectional, non-randomized study was carried out in 138 hospitalized patients of legal age in a fourth-level care institution with therapeutic and prophylactic anticoagulant treatment, addressing the type of drug indicated, periodicity, side effects, laboratory controls, pharmacological interactions and causality of adverse reactions. It was found that the anticoagulant with the highest frequency of use was enoxaparin (68%), the most used control was the prothrombin time (60.39%), pharmacological interactions were identified in 47.1%, being the most frequent with acetylsalicylic acid (29.7% of the total number of interactions), the most frequent adverse reactions were of a hematological nature (58.3%); and the causality assessment of adverse reactions was 4.2% probable. The study showed that the most used anticoagulant was enoxaparin. The pharmacological interactions of anticoagulants were very frequent, especially with warfarin. The most frequent adverse reactions were those of hemorrhagic type; and the causality assessment was of possible category for most of these adverse reactions.
