Aranidipine is a novel dihydropyridine derivative that gives rise to two active metabolites (M-1? and M-1?) that exhibit hypotensive activity. It is a calcium antagonist with the formula methyl 2-oxopropyl 1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-3,5-pyridi…
Azelnidipine is a dihydropyridine calcium channel blocker. It is marketed by Daiichi-Sankyo pharmaceuticals, Inc. in Japan. It has a gradual onset of action and produces a long-lasting decrease in blood pressure, with only a small increase in heart rate, unl…
Barnidipine is a long-acting novel calcium antagonist that belongs to the dihydropyridine (DHP) group of calcium channel blockers. Used in the treatment of hypertension, barnidipine displays high affinity for the calcium channels of the smooth muscle cells in…
A vasodilator agent found to be effective in a variety of peripheral circulation disorders. It has various other potentially useful pharmacological effects. Its mechanism may involve block of calcium channels.
Benzthiazide is used to treat hypertension and edema. Like other thiazides, benzthiazide promotes water loss from the body (diuretics). They inhibit Na+/Cl- reabsorption from the distal convoluted tubules in the kidneys. Thiazides also cause loss of potassium…
A long-acting, non selective, calcium channel blocker with significant anti-anginal activity. The drug produces significant coronary vasodilation and modest peripheral effects. It has antihypertensive and selective anti-arrhythmia activities and acts as a cal…
Calcitonin is a polypeptide hormone secreted by the parafollicular cells of the thyroid gland in mammals. It inhibits bone resorption and lowers both serum and urinary calcium concentrations. Human calcitonin is available only in very small quantities but has…
Calcitriol is an active metabolite of vitamin D with 3 hydroxyl (OH) groups and is commonly referred to as 1,25-dihydroxycholecalciferol, or 1alpha,25-dihydroxyvitamin D<sub>3</sub>, 1,25-dihydroxyvitamin D<sub>3</sub>. It is produced in the body after series…
Calcium plays a vital role in the anatomy, physiology and biochemistry of organisms and of the cell, particularly in signal transduction pathways. The skeleton acts as a major mineral storage site for the element and releases Ca2+ ions into the bloodstream un…
The chemical compound calcium acetate is the calcium salt of acetic acid. It has been commonly referred to as the acetate of lime. The anhydrous form is very hygroscopic, therefore the monohydrate is the common form.
Calcium carbimide, sold as the citrate salt, is an alcohol-sensitizing agent. Its effects are similar to the drug disulfiram (Antabuse) in that it interferes with the normal metabolism of alcohol by preventing the breakdown of the metabolic product acetaldehy…
