Generic Isordil Information

Introduction

Isordil is a prescription medication used primarily to prevent angina pectoris (chest pain) caused by coronary artery disease. Its active ingredient is isosorbide dinitrate, a nitrate vasodilator that belongs to the general health group of anti‑anginal agents. In the United Kingdom it is prescribed by cardiologists and general practitioners as part of long‑term management of stable angina and, in some cases, of heart failure with reduced ejection fraction.

What is Isordil?

Isordil is a tablet formulation containing the nitrate isosorbide dinitrate. It was first developed in the 196s as part of the nitrate class of cardiovascular drugs, following the discovery that organic nitrates can relieve myocardial oxygen demand. The product is manufactured by several licensed pharmaceutical companies; in the UK the most common commercial label is “Isordil” (also marketed under “Isordil SR” for sustained‑release tablets). Similar brand‑name products include Monoket and Isosorbide Dinitrate (generic), all of which deliver the same active compound.

How Isordil Works

Isosorbide dinitrate is converted in the vascular smooth‑muscle cell to nitric oxide (NO). NO activates guanylate cyclase, increasing cyclic GMP levels, which cause relaxation of smooth muscle in veins and, to a lesser extent, arteries. This vasodilation reduces preload (the amount of blood returning to the heart) and modestly decreases afterload, lowering myocardial wall stress and oxygen consumption. The net effect is relief of anginal symptoms and, in chronic use, improvement of exercise tolerance. Onset of action after oral administration is typically 15–30 minutes, with peak plasma concentrations reached in 1–2 hours. The drug’s half‑life is approximately 1 hour, but clinical effects may persist longer due to active metabolites.

Conditions Treated with Isordil

• Stable Angina Pectoris – Reduces frequency and severity of chest pain by decreasing myocardial oxygen demand.
• Chronic Heart Failure (NYHA II‑III) – Adjunct therapy to improve symptoms and exercise capacity, particularly when combined with ACE inhibitors or β‑blockers.
• Controlled Hypertension (off‑label) – Occasionally used when nitrate‑induced vasodilation assists blood‑pressure control.

In the UK, coronary artery disease affects about 2 million adults, making anti‑anginal therapy a common component of cardiovascular care. Clinical guidelines (NICE CG126) recommend long‑acting nitrates such as isosorbide dinitrate as second‑line agents after β‑blockers and calcium‑channel blockers.

Who is Isordil For?

• Adults with a confirmed diagnosis of stable angina who continue to have symptoms despite optimal β‑blocker therapy.
• Patients with heart failure with reduced ejection fraction who are already on guideline‑directed medical therapy and need additional symptom relief.
• Individuals who tolerate nitrate therapy without severe hypotension, reflex tachycardia, or intolerance (e.g., severe headache, flushing).

Isordil is generally not suitable for:

• Patients with known hypersensitivity to nitrates or any tablet excipient.
• Uncontrolled hypotension (systolic < 90 mmHg).
• Concurrent use of phosphodiesterase‑5 inhibitors (e.g., sildenafil) due to risk of profound vasodilation.

Risks, Side Effects, and Interactions

Common

• Headache (often described as “nitrate headache”)
• Flushing or warmth in the face and neck
• Dizziness, particularly when standing quickly

Rare

• Hypotension requiring medical attention
• Palpitations or tachycardia
• Nausea or mild abdominal discomfort

Serious

• Severe hypotension with syncope
• Methemoglobinemia (extremely rare, characterized by cyanosis and shortness of breath)
• Life‑threatening allergic reactions (anaphylaxis)

Drug‑Drug Interactions

• Phosphodiesterase‑5 inhibitors (sildenafil, tadalafil, vardenafil): additive vasodilatory effect → contraindicated.
• Other vasodilators (hydralazine, other nitrates, ACE inhibitors): may enhance hypotensive risk; dose adjustment required.
• Alcohol: potentiates vasodilation, dizziness or fainting.

Patients should disclose all current medications, herbal supplements, and over‑the‑counter products to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard oral dosing for chronic angina is 5 mg two to three times daily, with a drug‑free interval of at least 8 hours to reduce tolerance. Sustained‑release formulations may be prescribed at 20–40 mg once daily.
• Missed dose – Take the missed tablet as soon as remembered unless it is within 4 hours of the next scheduled dose; in that case skip the missed dose and continue the regular schedule. Do not double up.
• Overdose – Symptoms may include severe hypotension, fainting, and rapid heart rate. Seek emergency medical care immediately; treatment focuses on supportive measures and intravenous fluids.
• Food & alcohol – Isordil can be taken with or without food; however, a full stomach may delay absorption slightly. Avoid excessive alcohol as it can aggravate hypotension and dizziness.
• Comorbidities – In patients with hepatic impairment, dose reduction may be required because isosorbide dinitrate is metabolised hepatically. Renal impairment does not substantially affect clearance but monitoring is advised.

FAQ

• What is the typical appearance of an Isordil tablet?
  Isordil tablets are usually white, round, and debossed with the dosage strength (e.g., “5 mg”) on one side. The exact imprint may vary between manufacturers, but the colour and shape remain consistent across UK‑licensed supplies.

• Can Isordil be stored in a refrigerator?
  No special refrigeration is required. Tablets should be kept at controlled room temperature (15 °C–30 °C), protected from moisture, light, and heat. Storing them in a bathroom or near a radiator can reduce potency over time.

• Does exposure to sunlight degrade Isordil?
  longed exposure to direct sunlight may accelerate degradation of the nitrate bond, reducing effectiveness. Keep the medication in its original blister pack until use, and avoid leaving it on windowsills.

• Is there any difference between immediate‑release and sustained‑release Isordil?
  Immediate‑release tablets deliver the full dose quickly, requiring multiple daily administrations and a nitrate‑free interval to prevent tolerance. Sustained‑release (SR) tablets release the drug gradually, allowing once‑daily dosing with a lower risk of tolerance but a slightly delayed onset of action.

• Can I travel internationally with Isordil tablets?
  Yes, provided you carry the medication in its original labelled packaging and have a copy of the prescription or a doctor’s letter if requested by customs. The UK allows personal import of up to a three‑month supply for personal use, subject to NHS or private prescription verification.

• Are there any known differences in formulation between UK‑sourced and overseas Isordil?
  The active ingredient, isosorbide dinitrate, is identical across all reputable sources. Inactive excipients (e.g., microcrystalline cellulose, lactose) may vary slightly, but these differences do not affect clinical efficacy. All formulations sold through regulated channels meet the MHRA’s quality standards.

• What should I do if I develop a severe headache while taking Isordil?
  Mild to moderate nitrate headaches are common and often improve with regular dosing. If the headache is severe, persistent, or interferes with daily activities, contact a healthcare professional; dose adjustment or addition of an analgesic may be recommended.

• Does Isordil interfere with drug testing for employment or sport?
  No, isosorbide dinitrate is not a prohibited substance on standard occupational or anti‑doping panels. However, routine toxicology screens may detect nitrates, which can be explained with a prescription if required.

• Can I take Isordil with nicotine replacement therapy (e.g., patches)?
  Nicotine vasodilates and may potentiate the blood‑pressure‑lowering effect of nitrates, increasing the risk of hypotension. If using nicotine replacement, monitor blood pressure closely and discuss any symptoms with a clinician.

• Why is a nitrate‑free interval recommended in the dosing schedule?
  Continuous exposure to nitrates can lead to tachyphylaxis, where the body’s response diminishes. A drug‑free period (usually at night) allows restoration of nitrate sensitivity, preserving therapeutic benefit over the long term.
