75695-93-1 Usage
Description
Isradipine is a long-acting calcium blocker effective in the treatment of essential
hypertension. The advantages of isradipine as compared with other dihydropyridine
calcium antagonists include a "gentle" onset and fewer contraindications. It can be taken
by patients with diabetes mellitus, chronic obstructive airway diseases, gout, congestive
heart failure or ischemic heart disease.

Uses
Different sources of media describe the Uses of 75695-93-1 differently. You can refer to the following data:
1. Isradipine is a L-type calcium channel blocker, Isradipine has anti-atherosclerotic effects in animals and improves endothelium-mediated nitric oxide (NO)-dependent vasodilation in vitro. Additional studies indicate that Isradipine may provide a neuroprotective effect in a rat model of focal ischemia and that Isradipine produces a dose-dependent sparing of dopamine neuronal fibers and cell bodies.
2. nonsedating H1-antihistamine
3. Dihydropyridine calcium channel blocker. Antihypertensive; antianginal
Brand name
Dynacirc (Reliant);Prescal.
General Description
Isradipine, 4-(4-benzofuranazyl)-1,4-dihydro-2,6-dimethyl-3,5-pyridinecarboxylic acid methyl 1-methylethyl ester (DynaCirc), is another second-generationdihydropyridine-type channel blocker. This drug, like theother second-generation analogs, is more selective for vascularsmooth muscle than for myocardial tissue. It is effectivein the treatment of stable angina, reducing the frequencyof anginal attacks and the need to use nitroglycerin.
Biological Activity
Potent and selective L-type voltage-gated Ca 2+ channel blocker. EC 50 and pA 2 values are 1.4 nM and 10.3 for relaxation of depolarization- and Ca 2+ -induced contractions of rabbit aorta respectively; EC 25 = 0.45 nM for reduction in rate of spontaneously beating guinea pig right atria. Long-acting antihypertensive agent in vivo , exerting primary effects on vascular tissue with secondary negative chronotropic action.
Biochem/physiol Actions
L-type calcium channel blocker (also referred to as dihydropyridine-type calcium channel blocker); antihypertensive.

Check Digit Verification of cas no
The CAS Registry Mumber 75695-93-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,9 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75695-93:
(7*7)+(6*5)+(5*6)+(4*9)+(3*5)+(2*9)+(1*3)=181
181 % 10 = 1
So 75695-93-1 is a valid CAS Registry Number.
