No specific pharmacological effects mentioned

This product is a calcium channel blocker that can prevent cell damage caused by pathological intracellular calcium overload due to ischemia and other reasons; relieve vasospasm, and have a lasting inhibitory effect on persistent vasospasm caused by vasoconstrictor substances, especially on the basilar artery and internal carotid artery; has vestibular inhibitory effect, can increase blood flow in the cochlear arterioles and improve vestibular organ circulation; has anti-epileptic effect, can block pathological calcium overload of nerve cells to prevent paroxysmal depolarization and cell discharge, thereby avoiding epileptic seizures; protects the myocardium, and significantly reduces ischemic myocardial damage; improves renal function, and can be used for chronic renal failure; in addition, this product also has anti-histamine effect.

Has antipyretic, analgesic and anti-inflammatory effects

Calcium ion antagonists dilate coronary arteries, antagonize coronary artery spasm, and reduce myocardial oxygen consumption by regulating the influx of calcium ions on the cell membranes of myocardial conduction cells, myocardial contractile cells, and arterial smooth muscle cells; they prolong the effective refractory period of the atrioventricular node, slow conduction, and reduce the ventricular rate in patients with chronic atrial fibrillation and atrial flutter; they reduce the vascular resistance of the systemic circulation to produce a hypotensive effect; they inhibit myocardial contraction and improve left ventricular diastolic function.

Calcium ion antagonists, by regulating the influx of calcium ions on the cell membranes of myocardial conduction cells, myocardial contractile cells, and arterial smooth muscle cells, dilate coronary arteries, antagonize coronary artery spasm, reduce total peripheral resistance, lower ventricular rate, lower blood pressure, and improve left ventricular diastolic function. They may have a local anesthetic effect.
