Alcohol Tolerance occurs when regular drinking or drug use causes changes in the brain’s function and structures, and the metabolism adapts to the regular presence of drugs in the body.As a result, it takes increasingly higher doses of a psychoactive substance to get the same … This theory gives support to why relapse may occur even after long period of abstinence. considered to be a platform with good drug tolerance Assay design: Recommend a stepwise approach for assays with issues with drug tolerance Assay format: Most assays incorporate acid dissociation in the standard format defined by Patton et al which generally gives 10 to 100 fold improvement in drug tolerance. In this way, it is necessary to increase the dose of the substance to feel the effects of it again. tolerance [tol´er-ans] 1. the ability to bear something potentially difficult. - CHAPTER 11 Adolescence: Physical and Cognitive Development Figure 11.4: The Decline in Age at Menarche.
