WebWhile the exact cause of ADT tachyphylaxis in individual cases is unknown, drug tolerance is a more comprehensive model, as it includes mechanisms of pharmacodynamic tolerance, metabolic tolerance, and others. [5] Common examples [ edit] ADT tachyphylaxis specifically occurs in depressed patients using SSRIs and MAOIs. WebIncreasing its dosage can re-enhance the effects of the drug. This can, however, accelerate tolerance, further reducing the effects of the drug. Drug tolerance is predictive of drug use, but drug dependency or addiction is not inherently associated with it.

WebOct 1, 1995 · A clockwise hysteresis loop occurs when rapid tolerance (tachyphylaxis) develops. The response for a given plasma concentration is initially high, but decreases as tolerance rapidly develops. Examples are cocaine or indirectly acting sympathomimetic drugs such as pseudoephedrine. Psychedelics such as LSD-25 and psilocybin-containing mushrooms demonstrate very rapid tachyphylaxis. In a patient fully withdrawn from opioids, going back to an intermittent schedule or maintenance dosing protocol, a fraction of the old tolerance level will rapidly develop, usually starting two days after therapy is resumed and, in general, leveling off after day 7.
