| 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. (12 Dec 1998) |
| respiratory system agents | Drugs used for their effects on the respiratory system. (12 Dec 1998) |
| peripheral nervous system agents | Drugs that act principally at one or more sites within the peripheral neuroeffector systems, the autonomic system, and motor nerve-skeletal system. (12 Dec 1998) |
