    Pharmacodynamic tolerance refers to changes in response to a drug that result from adaptive changes excluding changes in the disposition how quickly does viagra work of the drug. Acute and chronic tolerance, and acute and chronic withdrawal, also have an important associative basis. Dispositional and pharmacodynamic. Dispositional tolerance is the decreased response to a drug with repeated administration due to a reduction in the amount of drug at its site of action.

    Tolerance to the rewarding effects of opioids with continuous administration, as measured by conditioned place preference, also has been observed. Although there is some evidence that metabolism to opioid drugs can be enhanced in tolerant animals, most opioid tolerance is thought to be pharmacodynamic (Jaffe, 1989. Jaffe and Martin, 1987). Two types of tolerance exist.

    Drug administration produces disturbances in the body (presumably largely via the brain for psychotropic effects), and these disturbances come to elicit unconditioned responses that compensate for the perturbation produced by the drug.
