Agonists are chemical substances that mimic or enhance the effects of neurotransmitters on the receptor sites of the next cell. If the neurotransmitter was excitatory, the effect of the agonist would be to increase the inhibitory. the agonist blockst the inhibitory effect.Antagonist drugs are chemical substances that block or reduce a cell's response to the action of other neurotransmitters.If the neurotransmitter is inhibitory, the antagonist would increase the activity of the cell.ntagonist drugs are chemical substances that block or reduce a cell's response to the action of other neurotransmitters.

Definition. An inverse agonist is a molecule that binds to the same site as an agonist and is considered to be a full agonist. However, it elicits the opposite effect to that of a normal agonist, i.e.: demonstrates negative efficacy.n antagonist reduces the effect of an agonist by preventing it from binding to receptors. Both antagonists and inverse agonists reduce the activity if a receptor and, in the presence of an agonist, reduce its activity.
