Webb1 apr. 2004 · One theoretical shortcoming of occupation theory is the ad hoc nature of the efficacy term. In 1989, Black and Leff [20] introduced a revolutionary idea that obviated the need for an empirical constant to account for efficacy; this formed the basis for the operational model. The ingenious premise on which this model is built is the fact that the … WebbThe receptor occupancy theory does not fully account for the existence of partial or inverse agonists, and it does not address the observation that the maximal response of some …
WebbThe occupancy theory of Gaddum and Clark states that the intensity of the pharmacological effect is directly proportional to the number of receptors occupied by the drug. Maximal response occurs when all the receptors are occupied.

A.J.Clark propounded the occupation theory which assumes that the extent to which a tissue is dependent on the proportion of its receptor population that has been occupied by a drug and maximal response is reached when all the receptors are occupied. He presumed that each occupied receptor delivered a constant unit of …
WebbReceptors rate theory The rate theory of Paton, as modified by Paton and Rang, rejects the assumption that the response is proportional to the number of occupied receptors, and instead proposes a relationship of response to the rate of drug-receptor complex formation.
