Diltiazem hydrochloride is a white to off-white crystalline powder with a bitter taste. It is soluble cardizem 20 mg 24 water, methanol, and chloroform. It has a molecular weight cardizem Cardizem CD is formulated as a once-a-day /how-often-can-you-take-maxalt-3-times-a-day.html capsule containing mg, mg, mg, mg, or mg diltiazem hydrochloride.
The therapeutic cardizem 20 mg 24 of Cardizem CD are believed cardizem be related to its ability to inhibit the cellular influx of calcium ions during membrane depolarization of cardiac and vascular smooth muscle.
Cardizem Cardizem produces its antihypertensive effect click by relaxation of vascular smooth muscle and the resultant decrease in peripheral vascular resistance. The cardizem 20 mg 24 of blood pressure reduction is related to the degree of hypertension; thus hypertensive individuals experience an antihypertensive effect, whereas there is only a modest fall in blood pressure in normotensives.
Cardizem CD has been shown to produce increases in exercise tolerance, probably due to its ability to reduce myocardial oxygen demand. This is accomplished via reductions in heart rate and systemic blood pressure at submaximal and maximal workloads.
Diltiazem has been shown to be a potent dilator /liv-52.html coronary arteries, both epicardial and subendocardial. Spontaneous and ergonovine-induced coronary artery spasms are inhibited by click cardizem 20 mg 24 see more. In animal models, diltiazem interferes with the slow inward depolarizing current in excitable tissue.
Cardizem 20 mg 24 causes excitation-contraction uncoupling in various myocardial cardizem without changes in the configuration of the action potential. Diltiazem produces relaxation of coronary vascular smooth muscle and dilation of both large and small coronary arteries cardizem 20 mg 24 drug levels that cause little or no cardizem 20 mg 24 inotropic effect.
The resultant increases in coronary blood flow epicardial and subendocardial occur in ischemic and nonischemic models cardizem are accompanied by dose-dependent decreases in systemic cardizem 20 mg 24 pressure and decreases in peripheral resistance.
Like other calcium channel antagonists, diltiazem decreases sinoatrial and atrioventricular conduction in isolated tissues and has a negative inotropic effect in isolated preparations. In the intact animal, prolongation of the AH interval can be seen cardizem higher doses. In man, cardizem 20 mg 24 prevents spontaneous and ergonovine-provoked coronary artery spasm.
It causes a decrease in peripheral vascular resistance and a modest fall in blood cardizem in normotensive individuals and, in exercise tolerance studies in patients with ischemic heart disease, reduces the heart rate-blood pressure product for any given cardizem 20 mg 24. Studies, primarily in cardizem with good ventricular function, have cardizem revealed evidence of a negative inotropic effect; cardiac output, ejection fraction, and left ventricular end diastolic pressure have not been affected.
Such data have no predictive value with respect to effects in patients with poor ventricular function, and increased heart failure has been cardizem 20 mg 24 in patients with preexisting impairment of ventricular function.
There are few data on the interaction of diltiazem and beta-blockers in patients with poor ventricular article source. Resting heart rate cardizem 20 mg 24 usually here reduced by diltiazem.
In hypertensive patients, Cardizem CD produces antihypertensive effects both in the supine and standing positions. In a double-blind, parallel, dose-response study utilizing doses ranging from 90 to mg once daily, Cardizem CD lowered supine cardizem blood pressure in an apparent linear manner over the entire dose range studied.
The changes in diastolic blood pressure, measured at trough, for placebo, 90 mg, cardizem 20 mg 24, mg, and mg were —2. Postural hypotension is infrequently noted upon suddenly assuming an upright position. No reflex tachycardia is associated with cardizem 20 mg 24 chronic antihypertensive effects.
Diltiazem is used to treat high blood pressure and to control angina chest pain. Diltiazem is in a class of medications called calcium-channel blockers.
What Is Diltiazem Cardizem? Diltiazem 90 mg-TEV, peach, oval,.
