According to the common view, their … WebSide Effects and Contraindications. Dihydropyridine CCBs can cause flushing, headache, excessive hypotension, edema and reflex tachycardia. Baroreceptor reflex activation of sympathetic nerves and lack of direct negative cardiac effects can make dihydropyridines a less desirable choice for stable angina than diltiazem, verapamil or beta-blockers.
WebMay 24, 2024 · The mechanism of action for non-dihydropyridines is similar, but they primarily block the influx of calcium into cardiac muscle cells (myocytes). Normally the influx of calcium into cardiac myocytes will increase the automaticity and conduction velocity of pacemaker cells, thereby increasing heart rate.
