What Are The Indications For Calcium Channel Blockers

There are three types of calcium channel blockers: the first type is phenylalkylamine, such as verapamil, the second type is dihydropyridine, nifedipine, and the third type is diltiazem. In clinical practice, there are three main uses: firstly, for antihypertensive drugs, which can effectively lower blood pressure, have a mild antihypertensive effect, can simultaneously lower systolic and diastolic blood pressure, and can also reverse left ventricular hypertrophy caused by hypertension. Secondly, for the treatment of arrhythmia, it can organize the entry of calcium ions into cells, inhibit the influx of extracellular calcium ions, suppress potassium ion channels, and reduce sinus node autonomy to exert anti arrhythmic effects. Thirdly, it can also have an anti angina effect, with the best effect on variant angina.
