Incorporate to Favorites ADD TO PLAYLIST TRANSCRIPT Drug dosage, or the amount taken around a particular period of time, is planned According to a program that also decides the frequency and route of drug administration.

Healthcare gurus have to take into consideration these factors when prescribing drugs, individualizing therapy dependant on individual attributes and optimizing treatment regimens to realize wished-for therapeutic results while minimizing the potential risk of adverse results.

– Exposure to Toxins: Environmental toxins or check here pollutants can interfere with drug metabolism or exacerbate drug-induced toxicity. For instance, exposure to cigarette smoke induces hepatic CYP1A2 enzymes, resulting in elevated metabolism of sure drugs like caffeine and theophylline.
