A molecular entity capable of accepting a hydron from a donor (Bronsted acid).

A drug that binds to but does not activate dopamine receptors, thereby blocking the actions of dopamine or exogenous agonists.

An agent that binds to but does not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous alpha-adrenergic agonists. alpha-Adrenergic antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.

Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or serotonergic agonists.

H1-receptor antagonists are the drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine.

Antipsychotic drugs which can have different modes of action but which tend to be more likely than second generation antipsychotics to cause extrapyramidal motor control disabilities such as body rigidity or Parkinson's disease-type movements; such body movements can become permanent even after treatment has ceased.
