Anatomy Agonist muscle, prime mover. A muscle that causes a particular movement to occur, creating a normal range of movement in a joint by contracting; a muscle which moves in one general direction. Molecular biology A ligand which binds a receptor at a site adjacent to the active site. Pharmacology Agonist medication. A chemical entity that does not naturally occur in the body and acts on one or more receptors (e.g., mu, delta, and kappa opiate receptors) by structural mimicry of the receptors’ natural ligand(s).

Opiate antagoniosts are drugs that bind to the opiate receptors without activating them and prevent agonists from binding to the receptors. In brief: Agonist definition. That means drugs that bind to and activate one of the opiate receptors on the surface of cells. There are a number of different opiate receptors. The mu receptor is the one responsible for pain relief. Opiate antagoniosts are drugs that bind to the opiate receptors without activating them and prevent agonists from binding to the receptors.

A competitive antagonist binds to the same site as the agonist but does not activate it, thus blocks the agonist’s action. A non-competitive antagonist binds to an allosteric (non-agonist) site on the receptor to prevent activation of the receptor. A reversible antagonist binds non-covalently to the receptor, therefore can be “washed out”.

Other drugs act on the receptor in a blocking role and are antagonists. An antagonist is a molecule that interferes with or prevents the action of the agonist. 2. A contracting muscle that is opposed by contraction of another associated muscle, the antagonist.

A drug that binds to and activates a receptor. Can be full, partial or inverse. A full agonist has high efficacy, producing a full response while occupying a relatively low proportion of receptors. A partial agonist has lower efficacy than a full agonist.

Efficacy spectrum of receptor ligands. An agonist is a chemical that binds to a receptor and activates the receptor to produce a biological response. Whereas an agonist causes an action, an antagonist blocks the action of the agonist and an inverse agonist causes an action opposite to that of the agonist. 1 Types of agonists.
https://en.wikipedia.org/wiki/Agonist
An inverse agonist produces an effect opposite to that of an agonist, yet binds to the same receptor binding-site as an agonist. A drug that binds to a receptor at a site distinct from the active site. Induces a conformational change in the receptor, which alters the affinity of the receptor for the endogenous ligand.

1. in physiology a muscle which in contracting to move a part is opposed by another muscle (the antagonist). 2. in pharmacology, a drug which has affinity for the cellular receptors of another drug or natural substance and which produces a physiological effect. adrenergic agonist (2) see adrenergic agents.
http://medical-dictionary.thefreedictionary.com/Receptor+agonist
Types of agonists[edit] Receptors can be activated by either endogenous (such as hormones and neurotransmitters) or exogenous (such as drugs) agonists, resulting in a biological response. A physiological agonist is a substance that creates the same bodily responses but does not bind to the same receptor.
