NITRO-BID SUMMARY
NITRO-BID®
(Nitroglycerin Ointment USP, 2%)
Nitroglycerin is 1,2,3-propanetriol trinitrate, an organic nitrate.
Nitroglycerin ointment is indicated for the prevention of angina pectoris due to coronary artery disease. The onset of action of transdermal nitroglycerin is not sufficiently rapid for this product to be useful in aborting an acute anginal episode.

Published Studies Related to Nitro-Bid (Nitroglycerin Topical)
Intravenous nitroglycerin for external cephalic version: a randomized controlled trial. [2009.09]
OBJECTIVE: To estimate whether treatment with intravenous nitroglycerin for uterine relaxation increases the chance of successful external cephalic version... CONCLUSION: Treatment with intravenous nitroglycerin increased the rate of successful external cephalic version in nulliparous, but not in multiparous, women. Treatment with intravenous nitroglycerin appeared to be safe, but our numbers were too small to rule out rare serious adverse effects. LEVEL OF EVIDENCE: I.
Transdermal nitroglycerin therapy may not prevent early postmenopausal bone loss. [2009.09]
CONTEXT: Osteoporosis is common among postmenopausal women; animal studies and human pilot studies support the concept of nitric oxide (NO) donors reducing bone mineral density loss. OBJECTIVE: The objective of the study was to evaluate whether NO donor, nitroglycerin, prevents postmenopausal bone loss... CONCLUSIONS: BMD changes did not substantially differ between postmenopausal women who received the dose of nitroglycerin tested, in comparison with a placebo. Once-daily dosing with 22.5 mg of transdermal-administered nitroglycerin was not effective (compliance adjusted dose was only approximately 16 mg/d); a sub-therapeutic dose.
Effects of nitroglycerin on sublingual microcirculatory blood flow in patients with severe sepsis/septic shock after a strict resuscitation protocol: A double-blind randomized placebo controlled trial. [2009.08.27]
OBJECTIVES:: Microcirculatory alterations have been associated with morbidity and mortality in human sepsis. Such alterations occur despite pressure-guided resuscitation. Earlier data suggested that impaired microcirculatory blood flow could be corrected with intravenous nitroglycerin in these patients. We tested this concept after fulfillment of preset systemic hemodynamic resuscitation end points in the early phase of sepsis... CONCLUSIONS:: In the context of a strict resuscitation protocol, based upon fulfillment of systemic hemodynamic end points in patients with early-phase severe sepsis or septic shock, we conclude that intravenous nitroglycerin does not promote sublingual microcirculatory blood flow.
The effect of nitroglycerin as an adjuvant to lidocaine in intravenous regional anesthesia. [2009.06]
PURPOSE: The disadvantages of intravenous regional anesthesia (IVRA) include slow onset, poor muscle relaxation, tourniquet pain, and rapid onset of pain after tourniquet deflation. In this randomized, double-blind study, we evaluated the effect of nitroglycerin (NTG) in quality improvement when added to lidocaine in IVRA... CONCLUSION: The NTG adding to lidocaine in intravenous regional anesthesia shortens onset times of sensory and motor block and decreases the tourniquet and postoperative pain, without any side effect.
Transdermal nitroglycerin as an adjuvant to patient-controlled morphine analgesia after total knee arthroplasty. [2009.03]
BACKGROUND: Nitroglycerin (NTG) has been shown to be a useful adjunct for pain treatment without increasing adverse side effects. The effects of NTG on postoperative morphine consumption after knee replacement were evaluated... CONCLUSIONS: The use of NTG patches conferred no advantage over the use of placebo in patients receiving patient-controlled morphine analgesia after total knee replacement. Two myocardial infarcts occurred in this group. Therefore, the safety of postoperative NTG patch use for pain control must be questioned.
Clinical Trials Related to Nitro-Bid (Nitroglycerin Topical)
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.
Blood Pressure Interaction Between Sildenafil and Sublingual Glyceryl Trinitrate (GTN) in Men With Angina [Completed]
The purpose of the study is to determine for how long sildenafil potentiates the blood
pressure reduction that occurs with glyceryl trinitrate in men with angina.
A Study of a Topical Form of Nitroglycerin and Placebo in the Treatment and Prevention of Raynaud's Phenomenon [Active, not recruiting]
The purpose of this research study is to test the safety, tolerability, and effectiveness of
Topical AmphiMatrix with Nitroglycerin (MQX0503) to relieve Raynaud's symptoms and increase
blood flow to the fingers.
Radial Artery Dilation Study: The Effect of Topical Administration of Nitroglycerin and Lidocaine Versus Lidocaine Alone of the Radial Artery Diameter [Recruiting]
The radial artery, which is located on the outer side of the forearm, can be used in
interventional procedures, such as cardiac catheterization, to provide access to the arterial
blood supply. In order to facilitate successful catheterization of the artery, a dilated
artery and one free of arterial spasm is desirable. The proposed study will randomize twenty
three healthy subjects to determine the effect of topical nitroglycerin on radial artery
vasodilation. In the first phase of the study, which is a dose escalation study, each subject
will receive either one or two inches of nitroglycerin in a blinded manner on one wrist and
placebo on the other. Radial artery diameter will be measured with ultrasound at regular
intervals up to two hours. The subjects will then return at a later date at which point they
will receive the alternate dose on one wrist and placebo on the other. In the second phase of
the study, we will randomize the same patients to a mixture of topical nitroglycerin and
lidocaine or topical lidocaine alone. Measurements of radial artery diameter will be
performed as in the first study.
Dose Response to Topical Glyceryl Trinitrate in Patients With Raynaud's Phenomenon [Recruiting]
The purpose of this study is to evaluate the blood flow response to topical Glyceryl
Trinitrate when applied to the skin of patient's fingers with Raynaud's Phenomenon.
