Central nervous system agents

a class of drugs producing both physiological and psychological effects through a variety of mechanisms. They can be divided into specific agents, e.g., affecting an identifiable molecular mechanism unique to target cells bearing receptors for that agent, and non-specific agents, those producing effects on different target cells and acting by diverse molecular mechanisms. Those with non-specific mechanisms are generally further classed according to whether they produce behavioural depression or stimulation. Those with specific mechanisms are classed by locus of action or specific therapeutic use.
