The present work showed that the iontophoretic approach was feasible to enhance transdermal drug delivery of drug. In vitro horizontal cell has been developed to co-relate with in vivo iontophoretic drug delivery more closely. Two electrodes were positioned on the either side of the epithelial. Iontophoretic delivery of Diltiazem HCl across porcine ear skin increased proportional to (a) Increas...

Since the calcium antagonists nifedipine and verapamil have been shown to diminish exercise induced asthma, the effect of oral diltiazem, a calcium channel blocker not previously investigated in this context, was studied. Ten patients with bronchial asthma were given 60 mg diltiazem or placebo four hours before the challenge in a double blind, randomised, crossover fashion. Exercise was perform...

The efficacy of diltiazem in the treatment of Raynaud's phenomenon was assessed in a prospective double-blind randomised cross-over trial in 16 patients (7 progressive systemic sclerosis, 2 rheumatoid arthritis, 1 systemic lupus erythematosus, and 6 idiopathic Raynaud's phenomenon). Each patient received diltiazem 120 mg and placebo three times a day for two weeks. The attack frequency of Rayna...

BACKGROUND Patients with acute heart failure (HF) complicated by supraventricular tachyarrhythmia (SVT) often receive continuous intravenous infusion of landiolol or diltiazem for rate control. It is unclear whether the interval from initiation of infusion to commencement of oral beta-blocker (BB) therapy differs for these two drugs. METHODS From January 2013 to July 2015, 94 consecutive pati...

BACKGROUND Intracoronary (IC) calcium channel blockers (CCB) such as diltiazem and verapamil are frequently utilized during percutaneous coronary interventions to maximize coronary blood flow. Their use, however, may be limited by systemic side effects such as hypotension and bradyarrhythmias. The vasoselective dihydropyridines, such as nicardipine, may be more effective at increasing coronary ...

The aim of this study was to assess the feasibility of evaluating the therapeutic effects of intravenous diltiazem in a newly established rat model of coronary thrombotic micro-embolism (CME). CME was induced by injecting 0.199 ml saline containing 5 mg of automicrothrombotic particulates (∼10 μm) into the aorta of Sprague Dawley rats. The injection was carried out over 10 sec using a tuberculi...

INTRODUCTION Very few studies exist on the use of diltiazem in the prehospital setting. Some practitioners believe this medication is prone to causing hypotension in this setting. Our goals were to determine whether the prehospital administration of diltiazem induced hypotension and to evaluate the efficacy of the drug. METHODS Our two-tiered system is located in a suburban region of New Jers...

Formation of abdominal aortic aneurysms is a progressive inflammatory process that involves infiltration and differentiation of monocytes in the vessel wall, proliferation and migration of smooth muscle cells, and eventually the degradation of the internal elastic lamina, which leads to outward vascular remodeling and distension of the vessel. Because calcium channel blockers exert multiple ben...

Antiarrhythmic effects of intravenous coronary vasodilators (verapamil, diltiazem, bepridil, trimetazidine and nicorandil) were evaluated using two canine ventricular arrhythmia models (halothane-adrenaline arrhythmia and digitalis arrhythmia), and the minimum effective plasma concentrations of the drugs were determined for each arrhythmia model. Verapamil (0.1 mg/kg), diltiazem (0.1 mg/kg), be...
