Occupation theory – - There is a biomolecular, reversible interaction between drug (D) and receptor (R) leading to generation of drug-receptor complex (DR) in which binding of drug to receptor is an independent event. - Response size (E) is related to amount of drug- receptor complex.

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 … http://ecoursesonline.iasri.res.in/mod/page/view.php?id=64646 origami shapes easy

In 1901, Langley challenged the dominant hypothesis that drugs act at nerve endings by demonstrating that nicotine acted at sympathetic ganglia even after the degeneration of the severed preganglionic nerve endings. In 1905 he introduced the concept of a receptive substance on the surface of skeletal muscle that mediated the action of a drug. Langley postulated that these receptive substances were different in different species (citing the fact that nicotine-induc… WebbIntroduction Clark's occupancy theory for receptor response Chem Help ASAP 6.38K subscribers Subscribe 3.3K views 2 years ago medicinal - essentials of …
