Effect of the Addition of Vasopressin or Vasopressin Plus Nitroglycerin to Epinephrine on Arterial Blood Pressure during Cardiopulmonary Resuscitation in Humans. [2011.11]
Background: Infusion of a vasopressor during cardiopulmonary resuscitation (CPR) in humans increases end decompression (diastolic) arterial blood pressure, and consequently increases vital organ perfusion pressure and survival.
Nitroglycerin Ointment for the Prevention of Postmenopausal Osteoporosis (December). [2011.10.18]
OBJECTIVE:To determine whether clinical trial data support the use of nitroglycerin for prevention of postmenopausal osteoporosis.DATA SOURCES:A literature search using MEDLINE (1966-September 2011) and EMBASE (1973-September 2011) was conducted using the search terms nitroglycerin, bone mineral density, fracture, and osteoporosis...
Modulation of novel cardiorenal and inflammatory biomarkers by intravenous nitroglycerin and nesiritide in acute decompensated heart failure: an exploratory study. [2011.07]
CONCLUSIONS: The differential modulation effects of cystatin-C and interleukin-6 but not other inflammatory markers, in response to NES compared with NTG therapy, may provide important implications for vasodilator therapy. Further studies are warranted to confirm these findings. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT00842023.
Short-term aerobic exercise reduces nitroglycerin-induced orthostatic intolerance in older adults with type 2 diabetes. [2011.06]
AIMS/HYPOTHESIS: Older adults are at a high risk for syncope due to orthostatic intolerance (OI), and this risk increases with comorbid type 2 diabetes and vasoactive medications. Despite many benefits, previous investigations have shown worsening OI with aerobic training. We examined whether aerobic exercise reduced OI in older adults with type 2 diabetes who were given a short-acting vasoactive agent (nitroglycerin)... CONCLUSIONS: Our findings indicate that a relatively short aerobic exercise intervention can improve postnitroglycerin orthostatic tolerance in older adults with type 2 diabetes.
The potent calcitonin gene-related peptide receptor antagonist, telcagepant, does not affect nitroglycerin-induced vasodilation in healthy men. [2011.05]
AIMS: To assess the effect of the calcitonin gene-related peptide (CGRP) receptor antagonist, telcagepant, on the haemodynamic response to sublingual nitroglycerin (NTG)... CONCLUSIONS: Telcagepant did not affect NTG-induced haemodynamic changes. These data suggest that NTG-induced vasodilation is not CGRP dependent. (c) 2011 The Authors.

MQX-503 vs Nitroglycerin Ointment: A Pharmacokinetic Comparison in Normal Subjects [Completed]
The purpose of the study is to measure how much nitroglycerin or its metabolites may be found
in the bloodstream when MQX-503 or an FDA approved Nitroglycerin ointment 2% USP is applied
to the skin of healthy subjects.
Nitroglycerin in Non-small Cell Lung Cancer [Recruiting]
Nitroglycerin is a nitric oxide donor which is mainly known as a vasodilating agent used in
ischemic heart disease. It has also been shown to increase tumor blood flow in animal and
The addition of nitroglycerin to chemotherapy in non small cell lung cancer has been shown
to generate very favorable response rates with respect to standard treatment schedules.
Theoretically nitroglycerin might reduce resistance to chemotherapy via a plethora of
different effects: better tumor perfusion, direct effects of NO on cancer cells, increase in
activated p53 protein and via an increased blood flow in the tumour with as consequence a
higher drug concentration in the tumor  .
In mice, nitric oxide donors such as isosorbide dinitrate have been shown to decrease tumor
hypoxia by better tumor perfusion, which could enhance radiotherapy responses .
To date these combined effects have not been tested in humans. In this trial we would like
to demonstrate the effect of nitroglycerin on tumor perfusion and hypoxia in non small cell
lung cancer (using DCE and HX4 scanning), providing a rationale for further study and to
test the effect of combining nitroglycerine to standard treatment of NSCLC
GTN Therapy on Biomarkers of Immune Escape in Men With Biochemical Recurrence of Prostate Cancer After Primary Therapy [Recruiting]
Prostate cancer is the most commonly diagnosed cancer in men in Canada. Over 30% of men
over the age of fifty have histological evidence of prostate cancer on biopsy. Despite the
stage migration afforded by early detection with serum prostate specific antigen (PSA)
testing and an apparent trend toward improved survival over the past several years, prostate
cancer remains a significant cause of morbidity and mortality. Biochemical failure after
primary therapy (surgery or radiation) remains a significant health care burden and
strategies to delay clinical prostate cancer progression and prolong the interval from
treatment failure to systemic therapy would be of significant clinical benefit for those men
suffering from a finding of PSA recurrence.
PSA is widely accepted as the most useful prognostic marker of prostate cancer progression,
particularly after primary therapy with radical surgery or radiation. 5 Despite improved
cancer control rates with definitive management of early stage prostate cancer, a PSA
recurrence is unfortunately a common occurrence (25-50%) in most large case series.
Microenvironmental factors have been demonstrated to play a pivotal role in the selection of
neoplastic cell subpopulations expressing more malignant phenotypes and contributing to the
progression of localized and metastatic disease. Very low levels of O2 (< 10 mmHg) has been
well described in many solid tumours (including prostate cancer) and the extent of hypoxia
has been demonstrated to represent an independent marker of a poor prognosis for patients
with various types of cancers. Tumour hypoxia contributes to numerous adaptive phenotypes
including increased invasion and metastasis, as well as evasion of immune cell surveillance
increased resistance to radiotherapy and chemotherapy. Although cellular adaptive responses
to hypoxia are likely mediated by various mechanisms, our previous preclinical studies
suggest that decreased nitric oxide (NO)-dependent signalling plays a significant role in
this progression of a malignant phenotype.
Treatment of Suspected Cholelithiasis With Nitroglycerin [Not yet recruiting]
ABSTRACT: Sublingual nitroglycerin has been advocated for the treatment of acute pain from
suspected symptomatic cholelithiasis. There is, however, no clinical studies that validate
its use. This study is designed to evaluate the efficacy of nitroglycerine in relieving
acute pain of suspected biliary tract origin.
Nitroglycerin is a potent smooth muscle relaxant used for biliary tract dilation during
ERCP, (Chelly, J) and has been recommended for treatment of biliary colic based on
anecdotal experience and small case reports. Nitroglycerin effect is a result of the nitric
oxide component of the medication which acts as a smooth muscle relaxant in vascular,
bronchial, esophageal and biliary smooth muscles. [McGowan(1936), Chelly (1979),Toyoyama
(2001)] The typical dose of nitroglycerin is 0. 4 mg given sublingually in pill form or,
more recently, in a metered spray form. In a case series reported by Hassel (1993), positive
response times ranged from 20 to 60 seconds with duration of action of two to twelve hours.
Sublingual nitroglycerin is most commonly used for treatment of chest pain related to
insufficient cardiac perfusion. It has also been noted to relieve the pain of esophageal
spasms. Nitroglycerin has an excellent safety profile if used in patients with adequate
pretreatment blood pressures. [Newberry (2005), Nitroglycerine (2011), Nitro (2011), Wolters
(2009)] This study proposes to compare sublingual 0. 4 mg doses of nitroglycerin to placebo
for the initial treatment of acute pain from suspected symptomatic cholelithiasis
