|
Answer» Correct Answer - A Tranquillizers are used for the treatment of stress, fetigue , mild and severe mental dieases. They relieve anziety, stress, irritability or excitement by including a sense of well -being. Noradrenaline is one of the several neutransmitters which play an important role in mood changes. If the level of noradrenaline in the body is low for some reasons, then the message transfer proess becomes slow and the person suffe from depression. In such cases, antidepressant drugs are used. These drugs inhibits the enzymes which catalyses the degradation of noradrenaline. If the enzyme is inhibited, then the neurotansmitter noradrenaline is slowly metabolised and can thus activite the receptor for longer periods there by counteracting the effect of depression. Tranquillzers form an essential component of sleeping pills. |
