🎯 Indications and Usage ▾
1 INDICATIONS & USAGE Nitroglycerin Ointment 0.4% is indicated for the treatment of moderate to severe pain associated with chronic anal fissure. Nitroglycerin ointment is a nitrate vasodilator indicated for the treatment of moderate to severe pain associated with chronic anal fissure
⏱️ Dosage and Administration ▾
2 DOSAGE & ADMINISTRATION Apply 1 inch of ointment (375 mg of ointment equivalent to 1.5 mg of nitroglycerin) intra-anally every 12 hours for up to 3 weeks. A finger covering, such as plastic-wrap, disposable surgical glove or a finger cot, should be placed on the finger to apply the ointment. To obtain a 1.5 mg dose of nitroglycerin, the covered finger is laid alongside the 1 inch dosing line on the carton.
Refer to carton for accurate dosage guide. The tube is gently squeezed until a line of ointment the length of the measuring line is expressed onto the covered finger. The ointment is gently inserted into the anal canal using the covered finger no further than to the first finger joint and the ointment is applied around the side of the anal canal.
If this cannot be achieved due to pain, application of the ointment should be made directly to the outside of the anus. Treatment may be continued for up to three weeks. Nitroglycerin ointment is not for oral, ophthalmic, or intravaginal use.
Hands should be washed after application of the ointment. [see Patient Instruction ] Apply 1 inch of ointment (375 mg of ointment equivalent to 1.5 mg of nitroglycerin) intra-anally every 12 hours for up to 3 weeks. Nitroglycerin ointment is not for oral, ophthalmic, or intravaginal use.
💊 Dosage Forms and Strengths ▾

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Cardiovascular Disorders: Venous and arterial dilatation as a consequence of nitroglycerin treatment can result in hypotension. Exercise caution when treating patients with any of the following conditions: blood volume depletion, existing hypotension, cardiomyopathies, congestive heart failure, acute myocardial infarction, or poor cardiac function for other reasons ( 5.1 ). Headache: Nitroglycerin produces dose-related headaches which may be severe ( 5.2 )
5.1Cardiovascular Disorders Venous and arterial dilatation as a consequence of nitroglycerin treatment including nitroglycerin ointment, can decrease venous blood returning to the heart and reduce arterial vascular resistance and systolic pressure. Exercise caution when treating patients with any of the following conditions: blood volume depletion, existing hypotension, cardiomyopathies, congestive heart failure, acute myocardial infarction, or poor cardiac function for other reasons. If patients with any of these conditions are treated with nitroglycerin ointment, monitor cardiovascular status and clinical condition.
The adverse reactions of nitroglycerin ointment are likely to be more pronounced in the elderly.
5.2Headache Nitroglycerin ointment produces dose-related headaches, which may be severe. Tolerance to headaches occurs.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most common adverse reaction of nitroglycerin ointment applied to the anal canal is headache. Headache may be recurrent following each dose.
Headaches are typically of short duration and can be treated with an analgesic, e.g. acetaminophen, and are reversible upon discontinuation of treatment. In Study REC-C-001, a double-blind, placebo-controlled trial in patients with a painful chronic anal fissure, the most frequent (³ 2%) adverse reactions reported were as follows (Table 1): Table 1: Incidence of Adverse Reactions ( ³ 2%) in Study REC-C-001 Nitroglycerin ointment N = 123 Placebo N = 124 System Organ Class Preferred term Patients n (%) Events n Patients n (%) Events n Nervous system disorders Headache 79 (64) 938 51 (41) 225 Dizziness 6 (5) 26 0 0 Hypotension Transient episodes of light-headedness, occasionally related to blood pressure changes, also may occur.
Hypotension (including orthostatic hypotension) occurs infrequently, but in some patients may be severe enough to warrant discontinuation of therapy. Allergic Reactions Flushing, allergic reactions, and application site reactions (including drug rash and exfoliative dermatitis) have been reported rarely. Methemoglobinemia In rare cases, therapeutic doses of organic nitrates have caused methemoglobinemia [ see OVERDOSAGE(10) ] .
Most common adverse reactions are headache and dizziness. To report SUSPECTED ADVERSE REACTIONS, contact Solaris Pharma Corporation at 1-833-919-0527 or FDA at 1-800-332-1088 or www.fda.gov/medwatch .
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS PDE5 inhibitors: potentiation of hypotensive effects of organic nitrates; concomitant use is contraindicated. ( 4.1 , 7.1 ) Antihypertensives: possible additive hypotensive effects. ( 7.2 ) Aspirin: increased nitroglycerin levels.
( 7.3 ) Tissue-type Plasminogen Activator (t-PA): decreased thrombolytic effect. ( 7.4 ) Heparin: anticoagulant effect of heparin may be reduced. Monitor APTT.
( 7.5 ) Ergotamine: increased bioavailability of ergotamine. ( 7.6 ) Alcohol: Additive vasodilatory effects to nitroglycerin. Consumption of alcohol should be avoided.
( 7.7 )
7.1PDE5 Inhibitors Phosphodiesterase type 5 (PDE5) inhibitors such as sildenafil, vardenafil, and tadalafil have been shown to potentiate the hypotensive effects of organic nitrates. The time course of the interaction appears to be related to the half-life of the PDE5 inhibitor, however, the dose dependence of this interaction has not been studied. Use of nitroglycerin ointment within a few days of PDE5 inhibitors is contraindicated.
7.2Antihypertensives Patients receiving antihypertensive drugs, beta-adrenergic blockers, and other nitrates should be observed for possible additive hypotensive effects when using nitroglycerin ointment. Marked orthostatic hypotension has been reported when calcium channel blockers and organic nitrates were used concomitantly. Beta-blockers blunt the reflex tachycardia produced by nitroglycerin without preventing its hypotensive effects.
If beta-blockers are used with nitroglycerin ointment in patients with angina pectoris, additional hypotensive effects may occur.
7.3Aspirin Coadministration of aspirin (at doses between 500 mg and 1000 mg) and nitroglycerin has been reported to result in increased nitroglycerin maximum concentrations by as much as 67% and AUC by 73% when administered as a single dose. The pharmacological effects of nitroglycerin ointment may be enhanced by concomitant administration of aspirin.
7.4Tissue-type Plasminogen Activator (t-PA) Intravenous administration of nitroglycerin decreases the thrombolytic effect of tissue-type plasminogen activator (t-PA). Plasma levels of t-PA are reduced when coadministered with nitroglycerin. Therefore, caution should be observed in patients receiving nitroglycerin ointment during t-PA therapy.
7.5Heparin Although an interaction has been reported between intravenous heparin and intravenous nitroglycerin (resulting in a decrease in the anticoagulant effect of heparin), the data are not consistent. If patients are to receive intravenous heparin and nitroglycerin ointment concurrently, the anticoagulation status of the patient must be checked.
7.6Ergotamine Oral administration of nitroglycerin markedly decreases the first-pass metabolism of dihydroergotamine and consequently increases its oral bioavailability. Ergotamine is known to precipitate angina pectoris. Therefore the possibility of ergotism in patients receiving nitroglycerin ointment should be considered.
7.7Alcohol The vasodilating effects of nitroglycerin have been shown to be additive to the effects observed with alcohol.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no data on the use of nitroglycerin ointment intra-anally during pregnancy to determine a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproduction studies, no malformations were observed in offspring of pregnant rats and rabbits administered nitroglycerin by topical or dietary route during the period of organogenesis ( see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Animal reproduction studies in rats and rabbits were conducted with topically applied nitroglycerin ointment at doses up to 80 mg/kg/day and 240 mg/kg/day, respectively.
No toxic effects on dams or fetuses were seen at any dose tested. An animal reproduction study was conducted in rats with nitroglycerin administered in the diet at levels up to 1% content (approximately 430 mg/kg/day) on days 6 to 15 of gestation. In offspring of the high-dose group, an increased but not statistically significant incidence of diaphragmatic hernias was noted together with decreased hyoid bone ossification.
The latter finding probably reflects delayed development, thus indicating no clear evidence of a potential teratogenic effect of nitroglycerin.
8.2Lactation Risk Summary There are no data on the presence of nitroglycerin in either human or animal milk following topical administration, or the effects of nitroglycerin on milk production. A publication describing 40 lactating patients who used nitroglycerin ointment to treat chronic anal fissures for varied durations did not report signs of adverse effects in their breastfed infants, however, the dosing regimens were not described. The developmental and health benefits of breastfeeding should be considered along with the clinical need for nitroglycerin ointment and any potential adverse effects on the breastfed infant from nitroglycerin ointment or from the underlying maternal condition.
8.4Pediatric Use The safety and effectiveness of nitroglycerin ointment in pediatric patients under 18 years of age have not been established.
8.5Geriatric Use Clinical studies of nitroglycerin ointment did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Clinical data from the published literature indicate that the elderly demonstrate increased sensitivity to nitrates, which may be therapeutic but also manifest by more frequent or severe hypotension and related dizziness or fainting. Increased sensitivity may reflect the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Increased sensitivity may reflect the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE Nitroglycerin toxicity is generally mild. The estimated adult oral lethal dose of nitroglycerin is 200 mg to 1,200 mg. Infants may be more susceptible to toxicity from nitroglycerin.
Consultation with a poison center should be considered. Laboratory determinations of serum levels of nitroglycerin and its metabolites are not widely available, and such determinations have, in any event, no established role in the management of nitroglycerin overdose. No data are available to suggest physiological maneuvers (e.g., maneuvers to change the pH of the urine) that might accelerate elimination of nitroglycerin and its active metabolites.
Similarly, it is not known which, if any, of these substances can usefully be removed from the body by hemodialysis. No specific antagonist to the vasodilator effects of nitroglycerin is known, and no intervention has been subject to controlled study as a therapy of nitroglycerin overdose. Because the hypotension associated with nitroglycerin overdose is the result of venodilatation and arterial hypovolemia, prudent therapy in this situation should be directed toward increase in central fluid volume.
Passive elevation of the patient’s legs may be sufficient, but intravenous infusion of normal saline or similar fluid may also be necessary. The use of epinephrine or other arterial vasoconstrictors in this setting is not recommended. In patients with renal disease or congestive heart failure, therapy resulting in central volume expansion is not without hazard.
Treatment of nitroglycerin ointment overdose in these patients may be subtle and difficult, and invasive monitoring may be required. Methemoglobinemia Methemoglobinemia has been rarely reported with organic nitrates. The diagnosis should be suspected in patients who exhibit signs of impaired oxygen delivery despite adequate arterial PO 2 .
Classically, methemoglobinemic blood is described as chocolate brown, without color change on exposure to air. If methemoglobinemia is present, intravenous administration of methylene blue, 1 to 2 mg/kg of body weight, may be required.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Nitroglycerin forms free radical nitric oxide (NO), which activates guanylate cyclase, resulting in an increase of guanosine 3’,5’-monophosphate (cyclic GMP) in smooth muscle and other tissues. This leads to dephosphorylation of myosin light chains, which regulates the contractile state in smooth muscle and results in vasodilatation.
12.2Pharmacodynamics The principal pharmacological action of nitroglycerin is relaxation of vascular smooth muscle. Intra- anal application of nitroglycerin reduces sphincter tone and resting intra-anal pressure.
12.3Pharmacokinetics Absorption: In six healthy subjects, the average absolute bioavailability of nitroglycerin applied to the anal canal as a 0.2% w/w ointment was approximately 50% of the 0.75 mg nitroglycerin dose. Distribution: The volume of distribution of nitroglycerin following intravenous administration is about 3 L/kg. At plasma concentrations between 50 and 500 ng/mL, the binding of nitroglycerin to plasma proteins is approximately 60%, while that of 1,2- and 1,3-dinitroglycerin is 60% and 30%, respectively.
Metabolism: Nitroglycerin is metabolized by a liver reductase enzyme to glycerol di- and mononitrate metabolites and ultimately to glycerol and organic nitrate. Known sites of extrahepatic metabolism include red blood cells and vascular walls. In addition to nitroglycerin, the two major metabolites, 1,2- and 1,3- dinitroglycerols are found in plasma.
The contribution of metabolites to the relaxation of the internal anal sphincter is unknown. The dinitrates are further metabolized to nonvasoactive mononitrates and ultimately to glycerol and carbon dioxide. Elimination: Metabolism is the primary route of drug elimination.
Nitroglycerin plasma concentrations decrease rapidly with a mean elimination half-life of two to three minutes. Half-life values range from 1.5 to 7.5 minutes. Clearance (13.6 L/min) greatly exceeds hepatic blood flow.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Interaction with PDE5 Inhibitors Advise patient not to use nitroglycerin ointment with medications for erectile dysfunction such as Viagra (sildenafil), Levitra (vardenafil), and Cialis (tadalafil). These products have been shown to increase the hypotensive effects of nitroglycerin ointment and other nitrate drugs. [see Contraindications(4)] Hypotension Advise patients that treatment with nitroglycerin ointment may be associated with light-headedness on standing, especially just after rising from a lying or seated position.
The effect may be more frequent in patients who have also consumed alcohol, since alcohol use contributes to hypotension. Advise patients to stand up from the supine or sitting position slowly. Headaches Advise patients that headaches sometimes accompany treatment with nitroglycerin ointment.
For patients who get these headaches, the headaches may indicate the activity of the drug. Tolerance to headaches develops. Advise patients that if they experience headache they should not alter the schedule of their nitroglycerin ointment treatment to avoid the occurrence of headache.
An analgesic, such as acetaminophen, may be used to prevent or relieve the headaches. Dizziness Advise patients that dizziness has been reported as a side-effect of treatment with nitroglycerin ointment. Advise patients not to drive or operate machinery immediately after applying nitroglycerin ointment.
