As a consequence of reduce renal together with metabolic clearance, the elderly are liable to build cumulative toxicity whilst getting extended medication. Other affected aspects of drug dealing with are slower absorption as a result of reduced motility of and blood circulation to intestines, lesser plasma protein binding as a consequence of reduced plasma albumin, greater or decreased volume of distribution of lipophilic and hydrophilic drugs respectively.

– Exposure to Toxins: Environmental toxins or pollutants can interfere with drug metabolism or exacerbate drug-induced toxicity. For example, publicity to cigarette smoke induces hepatic CYP1A2 enzymes, leading to amplified metabolism of get more info certain drugs like caffeine and theophylline.
