Barbiturates are respiratory depressants. The degree of respiratory despair is dependent on dose. With hypnotic doses, respiratory depression made by barbiturates is similar to that which occurs for the duration of physiologic slumber with slight lessen in hypertension and coronary heart level.
Barbiturates are metabolized generally through the hepatic microsomal enzyme system, as well as metabolic items are excreted from the urine, and fewer generally, inside the feces.
