Sedatives and their types

Drugs of this group are able to lowerThe excitability of the central nervous system, to exert a regulatory influence on it, restoring the equilibrium between the processes of excitation and inhibition, and, if necessary, enhance the inhibition processes. Sedatives have a less pronounced psycho-sedative effect than tranquilizers, and do not possess hypnotic and miorelaxing properties, and, importantly, do not cause ataxia. With the systematic use of sedatives for a long time, mental drug dependence does not arise. In recommended therapeutic doses, sedatives can not have a hypnotic effect.

For example, valerian drug in addition to the sedative effect associated with a decrease in the excitability of the central nervous system, has antispasmodic properties, improves coronary circulation, regulates heart function, increases secretion of the glands of the gastrointestinal tract and improves bile secretion. Similar to valerian influences on the body is the motherwort, also having an antihypertensive effect and decreasing the heart rate. Passion flora and peony have an additional anticonvulsant effect. Melissa has antipruritic, antihypertensive, antispasmodic, and anti-arrhythmic action.
