WebIn the presence of full agonists, partial agonists act as antagonists competing for the same receptor sites. Inverse agonists produce an effect opposite to what is expected of an agonist. They bind receptors, reducing the number of the active ones. They can also bind inactive receptors, reducing the total possible pool of receptors. Webthe partial agonist interaction. In Figure 3.C, the partial agonist competes with the neurotransmitter for the receptor sites. As the partial agonist displaces the neurotransmitter, it changes the amount of R o and T o receptor forms (T o increases and therefore, the response decreases) until all the receptors have the partial agonist bound.
