Resumo: Bauhinia cheilantha (Leguminosae-Caesalpinioideae) é uma planta comum da caatinga amplamente utilizada na medicina popular como analgésica. Para verificar farmacologicamente este efeito, a atividade antinociceptiva desta planta foi verificada através do extrato aquoso da entre-casca, administrado em camundongos. O extrato (400 mg/kg), administrado por via oral 60 minutos antes do teste reduziu a nocicepção em 54,4%. Os efeitos da formalina (1%) também foram reduzidos pelo extrato em todas as doses. Naloxona (5 mg/kg, i.p.) e cafeína (10 mg/kg, i.p) também reverteram este efeito. No teste da placa quente o extrato de B. cheilantha nas doses 100mg, 200mg e 400 mg/kg, aumentou o tempo de latência em 39.8%, 30.7% e 32.8%, respectivamente. Não houve toxicidade aguda até a dose de 3g/Kg. O extrato aquoso da entre-casca de B. cheilantha mostrou atividade antinociceptiva nos modelos testados, efeito possivelmente associado com os sistemas opióide e adenosina. _________________________________________________________________________________________ ABSTRACT: Bauhinia cheilantha (Leguminosae: Caesalpinioideae) is a common plant of the Brasilian Caatinga widely used in folk medicine as an analgesic.
