NitroMist is contraindicated in patients with increased intracranial pressure.
NitroMist is indicated for acute relief of an attack or acute prophylaxis of angina pectoris due to coronary artery disease.
2 DOSAGE AND ADMINISTRATION
NitroMist is contraindicated in patients who have shown hypersensitivity to it or to other nitrates or nitrites.

NitroMist may be used prophylactically 5 minutes to 10 minutes before engaging in activities that might precipitate an acute attack.
As tolerance to other forms of nitroglycerin develops, the effect of sublingual nitroglycerin on exercise tolerance, although still observable, is reduced.
2.2 Priming the Container
After an initial priming of 10 sprays, each metered spray of NitroMist delivers 33 mg of solution containing 5.2 Hypotension

1,3-dinitroglycerin are found in plasma. The mean elimination half-life of both 1,2- and 1,3-dinitroglycerin is about 40 minutes. The 1,2- and 1,3-dinitroglycerin metabolites have been reported to possess some 7.6 Ergotamine

Oral administration of nitroglycerin markedly decreases the first-pass metabolism of dihydroergotamine and Higher plasma concentrations of the dinitro metabolites, with their nearly 8-fold longer elimination half-lives, subsequently increases its oral bioavailability. Ergotamine is known to precipitate angina pectoris. Therefore, may contribute significantly to the duration of pharmacologic effect.
patients receiving sublingual nitroglycerin should avoid ergotamine and related drugs or be monitored for symptoms of ergotism if this is not possible.
In the above referenced pharmacokinetic study the average initial half-lives (T½α) of nitroglycerin, and its 1,2- and 1,3-dinitroglycerin metabolites were estimated to be 3 minutes, 10 minutes, and 11 minutes, respectively. The 8 USE IN SPECIFIC POPULATIONS

Nitroglycerin also produces arteriolar relaxation, thereby reducing peripheral vascular resistance and arterial pressure (after load), and dilates large epicardial coronary arteries; however, the extent to which this latter effect contributes to the relief of exertional angina is unclear.
Therapeutic doses of nitroglycerin may reduce systolic, diastolic and mean arterial blood pressure. Effective coronary perfusion pressure is usually maintained, but can be compromised if blood pressure falls excessively or increased heart rate decreases diastolic filling time.
