All barbiturates exhibit anticonvulsant action in anesthetic doses. Having said that, of your drugs On this class, only phenobarbital, mephobarbital, and metharbital are effective as oral anticonvulsants in subhypnotic doses. Phenobarbital can be a respiratory depressant. The degree of respiratory depression is dependent upon the dose. With hypnotic doses, respiratory depression produced by Phenobarbital is analogous to that which occurs during physiologic sleep with slight decrease in blood pressure and heart fee. Scientific tests in laboratory animals have demonstrated that Phenobarbital causes reduction in the tone and contractility on the uterus, ureters, and urinary bladder. However, concentrations of your drug required to supply this effect in humans will not be reached with sedative-hypnotic doses. Phenobarbital does not impair normal hepatic function but continues to be shown to induce liver microsomal enzymes, So growing and/or altering the metabolism of barbiturates and other drugs. (See DRUG INTERACTIONS.)
two. Corticosteroids: Phenobarbital appears to boost the metabolism of exogenous corticosteroids in all probability throughout the induction of hepatic microsomal enzymes. Patients stabilized on corticosteroid therapy may perhaps need dosage adjustments if phenobarbital is additional to or withdrawn from their dosage regimen. 3. Griseofulvin: Phenobarbital appears to interfere with the absorption of orally administered griseofulvin, Consequently reducing its blood level. The effect in the resultant reduced blood levels of griseofulvin on therapeutic reaction has not been proven.
