Alterações hematológicas, bioquímicas e hemostáticas de cães tratados com anti-inflamatórios não esteroidais

Abstract

This study aimed to evaluate hematological and hemostatic parameters, cardiac and hepatic biomarkers in healthy dogs submitted to therapy with non-selective (NSAID) and COX-2 preferential nonsteroidal anti-inflammatory drugs. Were used 24 healthy dogs, randomly divided into 4 groups (G) submitted to therapy with ketoprofen, nimesulide, meloxicam and etodolac. The blood count, hemostatic profile (clotting time (CT), prothrombin time (PT), activated partial thromboplastin time (APTT), platelets and fibrinogen), cardiac biomarkers (CK, CKMB) and liver function (ALT, AST and albumin) were evaluate before, at 5 and 10 days (T0, T5, T10) of treatment. Were observed increase in CT in the ketoprofen and nimesulide groups at T5 and T10, respectivelly, when compared to T0. The etodolac group showed reduction in TP in T5 compared to T0. The platelet count increased at T10 compared to T0 and T5 in the ketoprofen group. The red blood cells and hematocrit decreased in at T10 in the ketoprofen group. Reduction of serum albumin occurred in the ketoprofen (T5 and T10) and nimesulide (T10) groups. In conclusion, meloxican was the safest drug to NSAID therapy in dogs. The NSAIDs ketoprofen, nimesulide and etodolac should be used judiciously in patients with dysfunction of coagulation profile, once that promote increase in coagulation parameters. Ketoprofen therapy requires attention for use in anemic dogs because they are able to reduce the red series, and in patients with hypoalbuminemia is contraindicated.
