Diltiazem is a calcium slow-channel blocking drug that may be effective in the treatment of chronic stable angina pectoris. To evaluate the therapeutic efficacy 3 hours after a single oral dose of 120 mg, 12 men with chronic stable angina pectoris performed a maximal exercise test on a bicycle ergometer after ingesting either placebo or diltiazem administered in a double-blind fashion. During s...

OBJECTIVE As an important prognostic factor of coronary artery bypass grafting (CABG), graft vasospasm can be observed in all currently used graft conduits. Radial artery (RA) vasospasm is more prone to occur in comparisons with internal mammary artery (IMA) and great saphenous vein (GSV). There is still controversy about which antispasmodic agent is superior to different grafts, especially to ...

To assess the effect of diltiazem on left ventricular systolic regional wall motion and diastolic function in patients with coronary artery disease (CAD), 22 patients underwent biplane left ventricular cineangiography before and after intravenous diltiazem (plasma concentration 154 +/- 12 ng/ml). Left ventricular and right ventricular pressures were measured by micromanometer-tipped catheters. ...

The pharmacokinetics (PK) of ordinary tablets and sustained release capsules of diltiazem hydrochloride in human clinical trials had been studied. The PK of diltiazem hydrochloride delay-onset sustained-release pellet capsules, a new dosage form, has not been reported, although it is very important to clinical use. In this paper, we investigated the PK of diltiazem hydrochloride delay-onset sus...

The effects of oral diltiazem (360 mg/day) on exercise tolerance, left ventricular performance, and plasma lactate and catecholamine levels were studied in 13 patients with atherosclerotic coronary artery disease in a placebo-controlled, randomized, double-blind protocol. Exercise duration to the onset of ischemic ST segment depression, time to angina pectoris, and time to peak exercise improve...

The goal of this study was to determine the effects of the L-type calcium channel blockers verapamil and diltiazem on the currents of voltage-gated potassium channel (fKv1.4ΔN), an N-terminal-deleted mutant of the ferret Kv1.4 potassium channel. Measurements were made using a two electrode voltage clamp technique with channels expressed stably in Xenopus oocytes. The fKv1.4ΔN currents displayed...

Diltiazem, a calcium channel blocker, is used in multiple divided doses daily, due to its short elimination half-life. Hence, administration as a modified release (MR) formulation is suggested. In this double blind cross-over trial, the pharmacokinetics and pharmacodynamics of diltiazem was studied in eight healthy Indian adults. Diltiazem was administered as single dose (60 mg) of the two form...

A 60% (W/W) simple ointment of Udumbar (Ficus glomeruta) was prepared. The cases of cervical erosion were selected from S.S. Hospital, Institute of Medical Sciences, Banaras Hindu University, Varanasi. The ointment was applied in the form of tampon following electric cauterization and compared the results with the triples sulpha ointment. It showed 95% cure rate as against 85% of Triple sulpha ...

BACKGROUND After EDTA-induced hypocalcaemia, healthy volunteers treated with diltiazem display more severe hyperparathyroidism than subjects on felodipine studied under identical conditions. Therefore patients with end-stage renal disease (ESRD) and severe secondary hyperparathyroidism might be particularly sensitive to this side-effect. METHODS To test this hypothesis, seven patients with ES...
