A double-blind, randomized, placebo-controlled study was conducted to test the peak and trough antianginal and antiischemic monotherapy efficacy and safety of a new extended-release formulation of nisoldipine (nisoldipine Coat Core [Bayer Corporation], 20 mg, 40 mg, and 60 mg once daily compared to
The effects of two antianginal drugs, nicorandil and isosorbide dinitrate (ISDN), on metabolism and function of the ischemic myocardium were studied in a preparation of multiple coronary occlusions in barbital-anesthetized dogs. The preparation consisted of three 5 min occlusions of the left
Mibefradil is the first of a new class of calcium antagonists (CAs), the tetralol derivatives, that selectively blocks the T-type calcium channel. The anti-anginal and anti-ischemic efficacy of mibefradil in patients with chronic stable angina pectoris was established in five placebo-controlled
BACKGROUND
Mibefradil, a newly approved antihypertensive and antianginal drug, is the first member of a new class of calcium antagonists (CAs), the tetralol derivatives, that selectively blocks T-type Ca2+ channels in contrast to classical CAs which, at therapeutic concentrations, block only L-type
OBJECTIVE
To determine the effects of nifedipine-GITS (GITS = gastrointestinal transport system) on angina and cardiovascular responses to stress-dobutamine infusion, we used ultrafast cine-computed tomography (CT) to assess regional wall motion, myocardial perfusion, and indices of ventricular
The effect of the new antianginal drug, nicorandil, was studied in several models of myocardial ischemia in anesthetized dogs. In animals subjected to an acute or chronic coronary artery occlusion, nicorandil produced increases in collateral perfusion when changes in aortic pressure were minimized.
There has been much interest in the effect of sex hormones on cardiovascular risk factors and as a therapeutic modality in both men and women. In this article, testosterone is considered as a possible therapy for cardiovascular disease. It has been shown that the level of serum testosterone
The use of dobutamine stress echocardiography for the evaluation of coronary artery disease is rapidly expanding. Despite its widespread use, the feasibility and safety of dobutamine stress echocardiography has not been sufficiently documented. Between November 1992 and June 1995, we performed 1000
Nifedipine, a calcium-channel-blocking agent, is widely used as an antianginal and antihypertensive drug. Cutaneous reactions to nifedipine are extremely rare. A review of the literature revealed only three additional cutaneous eruptions which include vasculitis, erythematous edema of the legs and
Twenty-one patients with chronic stable angina were treated with the calcium antagonist diltiazem. Dose titration studies involving 180, 270 and 360 mg/day were conducted using a blinded objective protocol. Improvement in exercise tolerance was observed at all dose levels, but the best reduction of
A multicenter, double-blind study was performed to compare the antianginal efficacy and safety of the new dihydropyridine calcium antagonist amlodipine with the benzothiazepine calcium antagonist diltiazem in patients with stable exertional angina pectoris. Following a 2-week placebo run-in period,
Long acting nitrate derivatives have varying hemodynamic effects of a piridoxilate-pentaerithrityle tetranitrate administration. The purpose of this study was to assess the hemodynamic effects of a piridoxilate-pentaerithrityle tetranitrate compound and measure their duration of action. The study
The development of vasodilator drugs that open the K+ channels in blood vessels has been of great academic and practical interest. The discoveries of the ATP-sensitive K+ channel and the glibenclamide-sensitive K+ channel have promoted these interests. In relation to this channel, the
Clinical experience with the calcium channel-blocking agents has established their efficacy in the therapy of painful and silent myocardial ischemia. Questions have arisen, however, about side-effect characteristics of these medications as clinical practice has led to utilization of higher doses of
MIBEFRADIL IN THE TREATMENT OF HYPERTENSION: The antihypertensive efficacy of mibefradil, a new selective transient (T)-channel calcium antagonist, was studied in eight randomized, double-blind, parallel-design trials: four placebo-controlled and four active drug-controlled versus other calcium
