⚕For healthcare professionals — Summary of Product Characteristics (SmPC)Full SmPC: dosage, interactions, contraindications, warnings+
4.1. Therapeutic indications
For the prophylaxis and long term management of angina pectoris.
As adjunctive therapy after acute myocardial infarction and chronic congestive heart failure.
4.2. Posology and method of administration
For oral administration
Tablet should be swallowed whole with water.
Isosorbide mononitrate 40 mg Tablets: one tablet daily, twice daily, or three times daily
Adults:
One tablet to be taken asymmetrically (to allow a nitrate low period) two or three times a day. The dosage may be increased up to 120mg per day.
Dosage regime should be designed according to the clinical response of the patient. Tablets should be taken after meals, unchewed with water.
The lowest effective dose should be used.
In patients taking one tablet twice daily the second dose should be taken 8 hours after the first dosage. If the dose is one tablet three times daily, take one every 6 hours and ensure 12 hours treatment-free interval every 24 hours
Paediatric population: The safety and efficacy of Isosorbide Mononitrate 40mg Tablets in children has not been established.
Elderly: There is no evidence to suggest that an adjustment of the dosage is necessary.
Treatment with Isosorbide mononitrate tablets, as with any other nitrate, should not be stopped suddenly. Both the dosage and frequency should be tapered gradually (see section 4.4)
Method of administration
For oral administration
4.3. Contraindications
Isosorbide mononitrate tablets should not be given to patients with a known sensitivity to isosorbide mononitrate, the listed ingredients or other nitrates.
Isosorbide mononitrate tablets should not be used in cases of acute myocardial infarction with low filling pressures, acute circulatory failure (shock, vascular collapse), or very low blood pressure (systolic blood pressure below 90 mmHg), hypertrophic obstructive cardiomyopathy (HOCM), constrictive pericarditis, cardiac tamponade, low cardiac filling pressures, aortic/mitral valve stenosis and diseases associated with a raised intra-cranial pressure e.g. following a head trauma and including cerebral haemorrhage.
Isosorbide mononitrate Tablets should not be used in patients with severe anaemia, severe hypotension, closed angle glaucoma or severe hypovolaemia.
Phosphodiesterase type-5 inhibitors (e.g. sildenafil, tadalafil and vardenafil) have been shown to potentiate the hypotensive effects of nitrates, and their co- administration with nitrates or nitric oxide donors is therefore contraindicated (see section 4.4 and 4.5)
During nitrate therapy, the soluble guanylate cyclase stimulator riociguat must not be used (see section 4.5).
4.4. Special warnings and precautions for use
Isosorbide mononitrate Tablets should be used with caution in patients who are suffering from hypothyroidism, hypothermia, malnutrition and severe liver or renal disease.
Isosorbide should be used with caution in patients who have a recent history of myocardial infarction low filling pressures e.g. in acute myocardial infarction, impaired left ventricular function (left ventricular failure), or orthostatic dysfunction. Reducing systolic blood-pressure below 90 mmHg must be avoided.
Symptoms of circulatory collapse may arise after first dose, particularly in patients with labile circulation.
This product may give rise to symptoms of postural hypotension and syncope in some patients. Severe postural hypotension with light-headedness and dizziness is frequently observed after the consumption of alcohol.
Hypotension induced by nitrates may be accompanied by paradoxical bradycardia and increased angina.
Isosorbide mononitrate Tablets contain lactose and therefore should not be used in patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.
In the event of an acute angina attack, a sublingual treatment such as a GTN spray or tablet should be used instead of Isosorbide mononitrate Tablets. The onset of action of Isosorbide mononitrate Tablets is not sufficiently rapid to be useful to treat an acute anginal attack.
If the tablets are not taken as indicated (see section 4.2), tolerance to the medication could develop. The lowest effective dose should be used.
Treatment with Isosorbide mononitrate, as with any other nitrate, should not be stopped suddenly. Both the dosage and frequency should be tapered gradually (see section 4.2)
In patients with decreased gastrointestinal transit time, a decrease in release of the active ingredient may occur.
Patients who undergo a maintenance treatment with Isosorbide mononitrate should be informed that they must not use phosphodiesterase inhibitor- containing products (e.g. sildenafil, tadalafil, vardenafil).
Isosorbide mononitrate therapy should not be interrupted to take phosphodiesterase inhibitor-containing products (e.g. sildenafil, tadalafil, vardenafil), because the risk of inducing an attack of angina pectoris could increase by doing so (see section 4.3 & 4.5).
Hypoxaemia
Caution should be exercised in patients with hypoxaemia and ventilation/perfusion imbalance due to lung disease or ischaemic heart failure.
As a potent vasodilator, isosorbide mononitrate could result in increased perfusion of poorly ventilated areas, worsening of the ventilation/perfusion imbalance, and a further decrease in the arterial partial pressure of oxygen. During treatment with isosorbide mononitrate alcohol should be avoided as it may potentiate the hypotensive effect of isosorbide mononitrate (see section 4.5).
4.5. Interaction with other medicinal products and other forms of interaction
Concurrent administration of drugs with blood pressure lowering properties, e.g. beta-blockers, calcium channel blockers, vasodilators, alprostadil, aldesleukin, ACE-inhibitor, monoamine oxidase inhibitor, angiotensin II receptor antagonists etc. and/or alcohol may potentiate the hypotensive effects of Isosorbide mononitrate Tablets. This may occur with neuroleptics and tricyclic antidepressants.
The concurrent intake of ISMN with ACE-inhibitors or arterial vasodilators could be a desirable interaction, unless the antihypertensive effects are excessive in which case consider reducing the dose of one or both drugs.
Any blood pressure lowering effect of Isosorbide mononitrate tablets will be increased if used together with phosphodiesterase type-5- inhibitors, which are used for erectile dysfunction (see special warning and contraindications). This may lead to life threatening cardiovascular complications. Patients who are on Isosorbide mononitrate therapy therefore must not use phosphodiesterase type-5 inhibitors. (e.g. sildenafil, tadalafil, vardenafil).
The use of isosorbide mononitrate with riociguat, a soluble guanylate cyclase stimulator, is contraindicated (see section 4.3) since concomitant use can cause hypotension.
Reports suggest that concomitant administration of Isosorbide mononitrate tablets may increase the blood levels of dihydroergotamine and its hypertensive effects.
Sapropterine (Tetrahydrobiopterine, BH4) is a cofactor for nitric oxide synthetase. Caution is recommended during concomitant use of sapropterine-containing medicine with all agents that cause vasodilation by affecting nitric oxide (NO) metabolism or action, including classical NO donors (e.g. glyceryl trinitrate (GTN), isosorbide dinitrate (ISDN), isosorbide 5-mononitrate (5-ISMN) and others).
4.6. Fertility, pregnancy and lactation
Pregnancy
Safety in pregnancy has not been established for isosorbide mononitrate. There is data that nitrates are excreted in breast milk and may cause methemoglobinemia in infants.
Therefore Isosorbide mononitrate tablets should only be used in pregnancy and during lactation if, in the opinion of the physician, the possible benefits of treatment outweigh the hazards.
Breast-feeding
The extent of excretion of isosorbide mononitrate in human breast milk has not been determined. Therefore caution should be exercised when administered to nursing women.
Fertility
There is no data available on the effect of isosorbide mononitrate on fertility in humans.
4.7. Effects on ability to drive and use machines
Dizziness, tiredness or blurred vision might occur at the start of the treatment.
The patient should therefore be advised that if affected, they should not drive or operate machinery. This effect may be increased by alcohol.
4.8. Undesirable effects
Frequency categories are defined according to the following convention:
Very common (≥1/10)
Common (≥1/100 to <1/10)
Uncommon (≥1/1,000 to <1/100)
Rare (≥1/10,000 to <1/1,000)
Very rare (<1/10,000)
Not known (cannot be estimated from the available data)
During administration of Isosorbide Mononitrate Tablets the following undesirable effects may be observed:
Nervous system disorders:
• very common: headache
• common: dizziness (including dizziness postural),somnolence
Cardiac disorders:
• common: tachycardia
• uncommon: angina pectoris aggravated
Vascular disorders:
• common: orthostatic hypotension
• uncommon: circulatory collapse (sometimes accompanied by bradyarrhythmia and syncope)
• not known: hypotension
Gastrointestinal disorders:
• uncommon: nausea, vomiting
• very rare: heartburn
Skin and subcutaneous tissue disorders:
• uncommon: allergic skin reactions (e.g. rash), flushing
• not known: dermatitis exfoliative
Immune system disorders:
• not known: angioedema
General disorders and administration site conditions:
• common: asthenia.
Severe hypotensive responses have been reported for organic nitrates and include nausea, vomiting, restlessness, pallor and excessive perspiration.
During treatment with Isosorbide Mononitrate Tablets, a temporary hypoxemia may occur due to a relative redistribution of the blood flow in hypoventilated alveolar areas. Particularly in patients with coronary artery disease this may lead to a myocardialhypoxia.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or by searching for MHRA Yellow Card in the Google Play or Apple App Store.
4.9. Overdose
Animal experience:
In rats and mice, significant lethality at oral doses of 1965 mg/kg and 2581 mg/kg, respectively, was observed.
Human experience:
Symptoms:
- Fall of blood pressure ≤90 mmHg
- Paleness
- Sweating
- Weak pulse
- Tachycardia
- Light-headedness on standing
- Headache
- Weakness
- Dizziness
- Nausea
- Vomiting
- Diarrhoea
Methaemoglobinaemia has been reported in patients receiving other organic nitrates. During isosorbide mononitrate biotransformation nitrite ions are released, which may induce methaemoglobinaemia and cyanosis with subsequent tachypnoea, anxiety, loss of consciousness and cardiac arrest. It cannot be excluded that an overdose of isosorbide mononitrate may cause this adverse reaction.
In very high doses the intracranial pressure may be increased. This might lead to cerebral symptoms.
General procedure:
• Stop intake of the drug
• General procedures in the event of nitrate-related hypotension
- Patients should be kept horizontal with the head lowered and legs raised
- Supply oxygen
- Expand plasma volume (i.v. fluids)
- Specific treatment for shock (admit patient to intensive care unit)
Special procedure:
• Raising the blood pressure if the blood pressure is very low.
• Treatment of methaemoglobinaemia
- Reduction therapy of choice with vitamin C, methylene-blue or toluidine- blue
- Administer oxygen (if necessary)
- Initiate artificial ventilation
- Hemodialysis (if necessary)
• Resuscitation measures
In case of signs of respiratory and circulatory arrest, initiate resuscitation measures immediately.
