Impact of Gene Polymorphism on Pharmacokinetics and Pharmaco-dynamics of Calcium Channel Blockers: A Narrative Review

A class of drugs known as calcium channel blockers (CCBs) is used to treat hypertension, angina, and arrhythmias. There are two subcategories of this medication class: dihydropyridines and non-dihydropyridines. Studies on CYP3A5*3, AGTR1 rs275653, ABCB1 (MDR1) rs1045642, and POR*28 A503V have all investigated the effects of SNPs on CCBs. This study will carry out more research to ascertain which SNPs have the most influence on the effectiveness of CCBs. The narrative reviews in this article come from a variety of sources. We performed searches in Pubmed, ScienceDirect, and Google Scholar using the terms "calcium channel blocker," "efficacy," "blood pressure response," "pharmacokinetic," and "polymorphism" OR "genetic" OR "genomic" to find pertinent articles. When prescription antihypertensive medications, particularly calcium channel blockers, it is important to take into account certain gene variants for example CYP3A5*3/*3, CYP3A4 *1G/*1G, MDR1 C3435T , RyR3 gene rs877087 because of their considerable effects.
