Verapamil

Product name:Verapamil
CAS: 52-53-9
Molecular Formula: C27H38N2O4
Molecular Weight: 52-53-9
Product description:White powder; Odourless. Easily dissolved in methanol, ethanol or chloroform, dissolved in water. Melting point is 140 ℃ 145 ℃.As calcium channel blockers (calcium channel blockers). Due to the inhibition of calcium within the flow can reduce cardiac diastolic depolarization rate automatically, and slowed the release of the sinoatrial node impulse, can also be slow conduction. Can slow down the forward conduction, it can eliminate the atrioventricular node. Foreign perivascular have expansion effect, make the blood pressure to drop, but weaker, generally can cause the heart rate slows, but also because of the drop in blood pressure and heart rate speeds up the reflective.

Verapamil Hydrochloride

Product name:Verapamil Hydrochloride
CAS: 152-11-4
Molecular Formula: C27H38N2O4·HCl
Molecular Weight: 491.07
Product description:Verapamil hydrochloride as the calcium ion antagonist. By regulating cardiac conduction cells, myocardial contraction and artery vascular smooth muscle cell membrane on the inflow of calcium ions, give play to the role of the pharmacology, but does not change the concentration of serum calcium.Verapamil reduce calcium ion flow, effective refractory period extension of the atrioventricular node, slow conduction, can reduce chronic ventricular rate of atrial fibrillation and atrial flutter patients; Reduce the frequency of paroxysmal room sex on the room tachycardia attacks.
