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

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

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

Any EC 3.4.21.* (serine endopeptidase) inhibitor that interferes with the action of prolyl oligopeptidase (EC 3.4.21.26).

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

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

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