Glyceryl Trinitrate Accord- Uk (Glyceryl Trinitrate)

Glyceryl Trinitrate Accord‑Uk is primarily indicated for the relief and prevention of chest pain associated with reduced coronary blood flow.

• Acute angina pectoris episodes, providing rapid symptom relief.
• Chronic stable angina as part of a long‑term management plan.
• Prophylaxis of angina attacks before physical exertion or emotional stress.
• Adjunct therapy in acute coronary syndrome to reduce myocardial oxygen demand.
• Use in diagnostic testing for coronary artery disease when vasodilator response is required.
• Management of variant (Prinzmetal) angina where coronary spasm is a factor.

Side effects of Glyceryl Trinitrate Accord‑Uk reflect its vasodilatory action and may vary in frequency.

Common

• Headache, often described as throbbing or pressure‑type.
• Flushing or warmth in the face and neck.
• Dizziness or light‑headedness, especially when standing quickly.
• Low blood pressure (hypotension) with a sensation of faintness.

Serious

• Severe hypotension leading to syncope.
• Rapid heart rate (tachycardia) or irregular rhythm.
• Allergic reactions such as rash, itching, swelling, or difficulty breathing.

Before prescribing Glyceryl Trinitrate Accord‑Uk, clinicians should evaluate several safety considerations to minimise risk.

• Known hypersensitivity to glyceryl trinitrate or other organic nitrates.
• Recent use of phosphodiesterase‑5 inhibitors (e.g., sildenafil) due to risk of profound hypotension.
• Severe anemia, increased intracranial pressure, or closed‑angle glaucoma.
• Unstable hemodynamic status, such as shock or severe heart failure.
• Pregnancy and lactation status, as safety data are limited.
• Concomitant use of other vasodilators or antihypertensive agents.
• Elderly patients may be more susceptible to blood‑pressure drops.

Glyceryl Trinitrate Accord‑Uk can interact with several medicines; understanding these interactions helps avoid adverse events.

Avoid

• Phosphodiesterase‑5 inhibitors (e.g., sildenafil, tadalafil) – may cause dangerous hypotension.
• Other nitrate preparations – risk of additive vasodilation and severe blood‑pressure fall.
• Guanylate cyclase stimulators – enhanced nitric‑oxide effects.

Use with caution

• Antihypertensive drugs (beta‑blockers, ACE inhibitors, calcium‑channel blockers) – monitor blood pressure.
• Alcohol – may increase vasodilatory response and dizziness.
• Diuretics – potential for amplified hypotensive effect.
