This report describes the use of diltiazem to control circulatory fluctuations during anaesthesia in five patients undergoing resection of a phaeochromocytoma. Diltiazem was administered continuously i.v. before anaesthesia and during surgery until the draining vein from the tumour had been ligated. Arterial pressure and systemic vascular resistance decreased in association with the infusion of...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013201536 DESCRIPTION A 64-year-old man presented with a 12-month history of angina. Following coronary angiography he underwent percutaneous coronary intervention with deployment of drug-eluting stents to the left anterior descending and main diagonal branch. He was discharg...

BACKGROUND Calcium antagonists are a first-line treatment for hypertension. The effectiveness of diltiazem, a non-dihydropyridine calcium antagonist, in reducing cardiovascular morbidity or mortality is unclear. We compared the effects of diltiazem with that of diuretics, beta-blockers, or both on cardiovascular morbidity and mortality in hypertensive patients. METHODS In a prospective, rando...

A new high-performance liquid chromatographic method has been developed for the determination of diltiazem in human cardiac tissue. Tissue samples are homogenized and digested with trypsin solution. Diltiazem and the internal standard are extracted with acetone. The extract is evaporated to dryness and reconstituted in potassium phosphate buffer. Samples are then cleaned up with solid-phase ext...

The authors would like to thank Professor Halil Dogan (Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkey) for informing them of the following error. The following sentence within the last paragraph of the ‘Diltiazem and Atrial Arrhythmias’ section, ‘‘A retrospective study evaluated 77 patients with supraventricular tachycardia treated with oral adenosine or intravenous di...

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...

INTRODUCTION Calcium channel blockers have an excellent effectiveness in the conservative management of chronic anal fissure (CAF). OBJECTIVES To assess the long-term results of management with diltiazem 2% ointment using a telephone questionnaire. METHODS A descriptive, retrospective study from March 2004 to March 2011 in patients with CAF on diltiazem 2%, 3 applications daily for 4-6 week...

Currently, there is still a lack of an optimal treatment for no reflow phenomenon (NRP). We analyzed the efficacy and safety of using nondihydropyridine calcium channel antagonists (NDHP, verapamil/diltiazem) in patients suffering from NRP. Eight RCTs with 494 participants were eligible for analysis. The pooling analysis showed that intracoronary verapamil/diltiazem injection significantly decr...

OBJECTIVE To further resolve the clinical equipoise on the choice of chemical sphincterotomy agent for early symptomatic relief of anal fissure by comparing the effectiveness of 2% Diltiazem gel with 0.2% Glyceryl TriNitrate. METHODS The randomized clinical trial was conducted at Aga Khan University Hospital, Karachi, from February 1, to July 30, 2008, and comprised 60 adult patients with ana...

UNLABELLED The aim of this study is to investigate the effect of ECG criteria which are used for the distinction between AVNRT and AVRT for the choice of treatment in patients with Supraventricular Tachycardia (SVT). The 77 patients with narrow QRS complex SVT which was treated with Adenosine or Diltiazem in the Emergency Department were evaluated retrospectively. All 12-lead ECG during tachyca...
