Calcium antagonists and sympathetic activity

A QUANTUM CHEMICAL STUDY OF STRUCTURE -ACTIVITY RELATIONSHIPS OF DIHYDROPYRIDINE CALCIUM ANTAGONISTS

Quantum chemical (MNDo)caleulations have beenused toelucidate the molecular properties and structure - activity relationships of dihydropyridine (DHP) type calcium antagonists. There is a good corielation between the net atomic charges on various atoms of the 4 - phenyl ring of dihydropyridines and pharmacological activity. .Also, activity decreases with increasing free rotation of the phen...

The Antiiflammtory Activity of calcium-channel antagonists on chronic inflammation in rat

calcium mobilization is known to be an important factor in the activation of cells involved in inflammation,so,calcium-channel antagonists are be expected ti exhibit antiinflammatory activity.in the present study,we evaluateted the antiinflammatory effects of two calcium channel blockers,verapamil and nifedipine on adjuvant induced chronic in flammation in rat paw.sixty adult male rats were div...

Clinical pharmacology of calcium antagonists. Satellite symposium on calcium antagonists.

A new class of agents has been made available for the treatment of hypertension. These calcium antagonists have rapid bioavailability and dramatic antihypertensive effects through reduction of total peripheral resistance and the vascular resistance of the major target organs of the body. These changes are usually associated with unchanged cardiac output, preserved organ blood flows, maintained ...
