With hypnotic doses, respiratory depression made by Phenobarbital is similar to that list of phenobarbital drugs which takes place for the duration of physiologic slumber with slight decrease in blood pressure and heart fee. Scientific tests in laboratory animals have shown that Phenobarbital results in reduction inside the tone and contractility of the uterus, ureters, and urinary bladder. Having said that, concentrations in the drug required to create this effect in people are certainly not arrived at with sedative-hypnotic doses. Phenobarbital isn't going to impair regular hepatic functionality but continues to be shown to induce liver microsomal enzymes, thus growing and/or altering the metabolism of barbiturates together with other drugs. (See DRUG INTERACTIONS.)
