Amlodipine benzenesulfonate and nifedipine are both calcium antagonists, but because ordinary nifedipine tablets are short-acting antihypertensive drugs for patients who take them, so amlodipine benzenesulfonate tablets are more helpful in lowering blood pressure more smoothly; ordinary nifedipine tablets have a faster onset of action, and for hypertensive emergencies, they can play a rapid role in lowering blood pressure.
