Aug 23, 2023 · Calcium channel blockers are medicines used to lower blood pressure. They stop calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to squeeze more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open. Calcium channel blockers (CCBs) are calcium ion antagonist. This means that they block the calcium ions movement between ion channels and ionophores [55]. Calcium ion movement is an important phenomenon that serves as secondary messenger. CCBs are specified therapy for a number of medical conditions, including hypertension and heart failure [55].The calcium channel blockers act by blocking the influx of calcium ions into vascular smooth muscle and cardiac muscle cells during membrane depolarization. Because muscle contraction is largely dependent upon influx of calcium, its inhibition causes relaxation, particularly in arterial beds.

Calcium channel blockers (CCBs) are commonly recommended as first-line antihypertensives that reduce blood pressure (BP), especially for hypertensive patients >60 years. CCB comprise drugs that disrupt the transport of calcium through calcium channels and reduce BP by acting on vascular smooth muscles to increase arterial diameter.
Antiarrhythmic medications help control arrhythmias or abnormal heartbeats. There are four main groups of antiarrhythmic medications: class I, sodium-channel blockers; class II, beta-blockers; class III, potassium-channel blockers; class IV, calcium-channel blockers; and miscellaneous antiarrhythmics, or unclassified antiarrhythmics.
