Antinociceptive effect of the ethanolic extract of Amburana cearensis (Allemão) A.C. Sm., Fabaceae, in rodents

Abstract: ABSTRACT:The ethanolic extract of the trunk bark of Amburana cearensis (EEA) was examined for its oral (p.o.) analgesic activity at the doses of 100, 200 and 400 mg/kg body weight. In the acetic acid-induced writhing test, the EEA (200 and 400 mg/kg, p.o.) reduced the number of writhing by 33.4% and 40.7%, respectively. Additionally, EEA (100, 200 and 400 mg/kg, p.o.) decreased by 77.5%, 79.7 and 91.3%, respectively, the paw liking time in the second phase of the formalin test. Therefore, EEA showed a dose-dep… Show more

“…Nociception induced with formalin is used to measure the potentials of a substance to relieve continuous moderate pain generated as a result of tissue injury [84]. Formalin induced acute and chronic phases of nociception are regarded to indicate neurogenic and inflammatory pain behaviors respectively.…”

“…A redução foi de 66% e 54% para morfina e ácido acetilsalicílico, respectivamente. (Oliveira et al, 2009). A reação a esse modelo também pode envolver estruturas neurais superiores, sendo assim os fármacos que atuam a nível central, como os opioides, são capazes de aumentar o tempo de latência de retirada da cauda.…”

“…o Potencial antinociceptivo Segundo a Associação Internacional para o Estudo da Dor (IASP) a dor pode ser conceituada como uma experiência sensorial e emocional desagradável, relacionada à lesão tecidual real ou potencial, ou descritas em termos desse tipo de dano. Tal manifestação fisiológica pode ser classificada de acordo com o tipo de lesão e com os mediadores envolvidos, podendo ser de origem: neurogênica, quando há lesão do tecido neuronal; neuropática, quando há disfunção de um nervo; psicogênica, acarretada por fatores psicológicos; ou nociceptiva, quando há estimulação excessiva dos nociceptores [33][34][35] .…”
