Overview

What is Nitroglycerin Slocaps?

Nitroglycerin is 1,2,3-propanetriol trinitrate, an organic nitrate whose structural formula is:

and whose molecular weight is 227.09. The organic nitrates are vasodilators, active on both arteries and veins.

Each NITROGLYCERIN SLOCAP®, for oral administration, contains 2.5 mg, 6.5 mg, or 9 mg of nitroglycerin. Each capsule also contains the following inactive ingredients: gelatin, lactose, pharmaceutical glaze, corn starch, sucrose, talc and other ingredients. In addition, the 2.5 mg capsule contains FD&C Blue #1, FD&C Red #3 and D&C Yellow #10; the 6.5 mg capsule contains FD&C Blue #1, D&C Red #33, FD&C Yellow #6, and D&C Yellow #10; and the 9 mg capsule contains FD&C Green #3, FD&C Yellow #6, D&C Yellow #10 and titanium dioxide.

How should I use Nitroglycerin Slocaps?

Nitroglycerin Slocaps® (Nitroglycerin) are indicated for the prevention of angina pectoris due to coronary artery disease. The onset of action of oral nitroglycerin is not sufficiently rapid for this product to be useful in aborting an acute anginal episode.

As noted above (), careful studies with other formulations of nitroglycerin have shown that maintenance of continuous 24- hour plasma levels of nitroglycerin results in tolerance (i.e., loss of clinical response). Every dosing regimen for Nitroglycerin Slocaps® should provide a daily nitrate-free interval to avoid the development of this tolerance. The minimum necessary length of such an interval has not been defined, but studies with other nitroglycerin formulations have shown that 10-12 hours is sufficient. Large controlled studies with other formulations of nitroglycerin show that no dosing regimen with Nitroglycerin Slocaps® should be expected to provide more than about 12 hours of continuous antianginal efficacy per day.

The pharmacokinetics of nitroglycerin capsules, and the clinical effects of multiple-dose regimens, have not been well studied. In clinical trials, the initial regimen of nitroglycerin capsules has been 2.5 to 6.5 mg three to four times a day, with subsequent upward dose adjustment guided by symptoms and side effects. In one trial, 5 of the 18 subjects were titrated up to a dose of 26 mg four times a day.


What interacts with Nitroglycerin Slocaps?

Allergic reactions to organic nitrates are extremely rare, but they do occur. Nitroglycerin is contraindicated in patients who are allergic to it.



What are the warnings of Nitroglycerin Slocaps?

In view of isolated reports associating phenytoin with exacerbation of porphyria, caution should be exercised in using this medication in patients suffering from this disease.


What are the precautions of Nitroglycerin Slocaps?

General

Severe hypotension, particularly with upright posture, may occur with even small doses of nitroglycerin. This drug should therefore be used with caution in patients who may be volume depleted or who, for whatever reason, are already hypotensive. Hypotension induced by nitroglycerin may be accompanied by paradoxical bradycardia and increased angina pectoris.

Nitrate therapy may aggravate the angina caused by hypertrophic cardiomyopathy.

As tolerance to other forms of nitroglycerin develops, the effect of sublingual nitroglycerin on exercise tolerance, although still observable, is somewhat blunted.

In industrial workers who have had long-term exposure to unknown (presumably high) doses of organic nitrates, tolerance clearly occurs. Chest pain, acute myocardial infarction, and even sudden death have occurred during temporary withdrawal of nitrates from these workers, demonstrating the existence of true physical dependence.

Some clinical trials in angina patients have provided nitroglycerin for about 12 continuous hours of every 24-hour day. During the nitrate-free intervals in some of these trials, anginal attacks have been more easily provoked than before treatment, and patients have demonstrated hemodynamic rebound and exercise tolerance. The importance of these observations to the routine, clinical use of oral nitroglycerin is not known.

Information For Patients

Daily headaches sometimes accompany treatment with nitroglycerin. In patients who get these headaches, the headaches are a marker of the activity of the drug. Patients should resist the temptation to avoid headaches by altering the schedule of their treatment with nitroglycerin, since loss of headache is likely to be associated with simultaneous loss of antianginal efficacy.

Treatment with nitroglycerin may be associated with lightheadedness on standing, especially just after rising from a recumbent or seated position. This effect may be more frequent in patients who have also consumed alcohol.

Drug Interactions

The vasodilating effects of nitroglycerin may be additive with those of other vasodilators. Alcohol, in particular, has been found to exhibit additive effects of this variety.

Marked symptomatic orthostatic hypotension has been reported when calcium channel blockers and organic nitrates were used in combination. Dose adjustments of either class of agents may be necessary.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Studies to evaluate the carcinogenic or mutagenic potential of nitroglycerin have not been performed. Nitroglycerin’s effect upon reproductive capacity is similarly unknown.

Pregnancy Category C

Animal reproduction studies have not been conducted with nitroglycerin. It is also not known whether nitroglycerin can cause fetal harm when administered to a pregnant woman or whether it can affect reproductive capacity. Nitroglycerin should be given to a pregnant woman only if clearly needed.

Nursing Mothers

It is not known whether nitroglycerin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when nitroglycerin is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in children have not been established.


What are the side effects of Nitroglycerin Slocaps?

Adverse reactions to nitroglycerin are generally dose-related, and almost all of these reactions are the result of nitroglycerin’s activity as a vasodilator. Headache, which may be severe, is the most commonly reported side effect. Headache may be recurrent with each daily dose, especially at higher doses. Transient episodes of lightheadedness, occasionally related to blood pressure changes, may also occur. Hypotension occurs infrequently, but in some patients it may be severe enough to warrant discontinuation of therapy. Syncope, crescendo angina, and rebound hypertension have been reported but are uncommon.

Allergic reactions to nitroglycerin are also uncommon, and the great majority of those reported have been cases of contact dermatitis or fixed drug eruptions in patients receiving nitroglycerin in ointments or patches. There have been a few reports of genuine anaphylactoid reactions, and these reactions can probably occur in patients receiving nitroglycerin by any route.

Extremely rarely, ordinary doses of organic nitrates have caused methemoglobinemia in normal-seeming patients; for further discussion of its diagnosis and treatment see .

Data are not available to allow estimation of the frequency of adverse reactions during treatment with Nitroglycerin Slocaps® (Nitroglycerin).


What should I look out for while using Nitroglycerin Slocaps?

Allergic reactions to organic nitrates are extremely rare, but they do occur. Nitroglycerin is contraindicated in patients who are allergic to it.

The benefits of oral nitroglycerin in patients with acute myocardial infarction or congestive heart failure have not been established. If one elects to use nitroglycerin in these conditions, careful clinical or hemodynamic monitoring must be used to avoid the hazards of hypotension and tachycardia. Because the effects of sustained release capsules are so difficult to terminate rapidly, sustained release capsules are not recommended in these settings.

Clinical Information

Chemical Structure

Clinical Pharmacology

The volume of distribution of nitroglycerin is about 3 L/kg and nitroglycerin is cleared from this volume at extremely rapid rates, with a resulting serum half-life of about 3 minutes. The observed clearance rates (close to 1 L/kg/min) greatly exceed hepatic blood flow; known sites of extrahepatic metabolism include red blood cells and vascular walls.

The first products in the metabolism of nitroglycerin are inorganic nitrate and the 1,2- and 1,3-dinitroglycerols. The dinitrates are less effective vasodilators than nitroglycerin, but they are longerlived in the serum, and their net contribution to the overall effect of chronic nitroglycerin regimens is not known. The dinitrates are further metabolized to (nonvasoactive) mononitrates and, ultimately, to glycerol and carbon dioxide.

To avoid development of tolerance to nitroglycerin, drug-free intervals of 10-12 hours are known to be sufficient: shorter intervals have not been well studied. In one well-controlled clinical trial, subjects receiving nitroglycerin appeared to exhibit a rebound or withdrawal effect, so that their exercise tolerance at the end of the daily drug-free interval was than that exhibited by the parallel group receiving placebo.

Reliable assay techniques for plasma nitroglycerin levels have only recently become available, and studies using these techniques to define the pharmacokinetics of oral nitroglycerin preparations have not been reported. Published studies using older techniques provide results that often differ, in similar experimental settings, by an order of magnitude.
