Chronic effects of propoxyphene napsylate on pregnant rats - Revista Brasileira de Ginecologia e Obstetrícia
The purpose of this study is to evaluate the effects of propoxyphene napsylate on the pregnancy of the rat. We used fifty pregnant rats divided into five groups. All the animals received daily 1 ml of the solution by gavage from day 0 to the 20th day of pregnancy. Group I – only distilled water (control); group II – aqueous solution of acacia 2% (vehicle); groups III, IV and V – respectively, 5, 15 and 45 mg/kg of weight of propoxyphene napsylate diluted in 2% acacia solution. The animals were weighed on days 0, 7, 14 and 20 of pregnancy. All animals were sacrificed on the 20th day of pregnancy. Our results showed that the animals treated with 45 mg/kg of propoxyphene napsylate presented reduction of the individual weights of the fetuses, as well as of the weights of the newborns and placentas. The difference betewwn number of resorptions, implantations and placentas of the treated groups was shown to be non significant cohen compered with the control groups.
