Collaboration among prescribers and pharmacists is crucial to share knowledge. It is usually valuable to acquire use of an proof-based mostly drug selection assistance Resource that focuses on more info Increased dosing for Specific populations.
– Exposure to Toxins: Environmental toxins or pollutants can interfere with drug metabolism or exacerbate drug-induced toxicity. As an illustration, publicity to cigarette smoke induces hepatic CYP1A2 enzymes, bringing about enhanced metabolism of sure drugs like caffeine and theophylline.
