Minitran 5 (Glyceryl Trinitrate)

Glyceryl Trinitrate, the active ingredient in Minitran 5, is a nitrate vasodilator presented as a transdermal patch for systemic use. It treats angina pectoris by reducing myocardial oxygen demand in patients with chronic stable angina.

GNH USA supplies Minitran 5 as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Glyceryl Trinitrate, a nitrate vasodilator, is indicated for conditions related to myocardial ischemia. - Angina pectoris: provides rapid relief of chest pain and reduces the frequency of attacks. - Chronic stable angina: helps prevent episodes of chest pain during exertion. - Acute angina episodes: delivers nitrate to alleviate sudden ischemic discomfort.

Common Side Effects: - Headache: throbbing pain often occurring shortly after patch application. - Flushing: warmth and redness of the skin, especially on the face. - Dizziness: light‑headed sensation due to blood pressure reduction. - Hypotension: mild to moderate drop in blood pressure. - Tachycardia: compensatory increase in heart rate. - Skin irritation at the patch site: redness or itching.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure leading to syncope. - Syncope: sudden loss of consciousness. - Myocardial infarction: rare occurrence of heart attack. - Methemoglobinemia: abnormal hemoglobin causing reduced oxygen delivery. - Severe skin reactions: blistering or necrosis at the application site. - Allergic reactions: rash, swelling, or anaphylaxis.

Before using Minitran 5, consider the following precautions: - Severe hypotension: avoid use in patients with markedly low blood pressure. - Phosphodiesterase‑5 inhibitors: do not combine with sildenafil or similar drugs due to risk of profound hypotension. - Blood pressure monitoring: check blood pressure regularly during therapy. - Patch site rotation: change application site to prevent local skin irritation. - Patient education: instruct on proper patch removal to reduce nitrate tolerance. - Store at room temperature: keep in original packaging, protect from moisture and light.

Glyceryl trinitrate may interact with several medications.

Major Interactions (Avoid): - Sildenafil and other PDE5 inhibitors: can cause severe hypotension. - Other nitrates (e.g., isosorbide dinitrate): additive vasodilatory effect may lead to dangerous blood pressure fall. - Antihypertensive agents (e.g., ACE inhibitors, beta‑blockers): may enhance blood pressure lowering.

Moderate Interactions (Monitor Closely): - Alcohol: may increase hypotensive effect. - Diuretics: can potentiate blood pressure reduction. - CYP3A4 inhibitors (e.g., erythromycin): may raise plasma nitrate levels.
