Nitriderm Tts (Glyceryl Trinitrate)

Glyceryl trinitrate, the active ingredient in Nitriderm Tts, is an organic nitrate presented as a transdermal patch for transdermal use. It treats angina pectoris and is used in patients with chronic stable angina.

GNH USA supplies Nitriderm Tts as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nitriderm Tts, containing glyceryl trinitrate, is used in the anti‑anginal pathway to prevent myocardial ischemia.

Prophylaxis of angina pectoris: reduces the frequency of angina attacks. Management of chronic stable angina: improves exercise tolerance and reduces symptom burden. Prevention of exertional angina: provides sustained nitrate delivery during physical activity.

Adverse reactions may occur with any nitrate therapy.

Common Side Effects: - Headache: often transient and dose‑related. - Flushing: warmth and redness of the skin. - Dizziness or light‑headedness: due to blood pressure lowering. - Hypotension: especially on standing. - Skin irritation at the patch site: erythema or itching. - Tachycardia: reflex increase in heart rate.

Serious or Rare Side Effects: - Severe hypotension: can lead to syncope. - Syncope: sudden loss of consciousness. - Myocardial infarction: rare but reported. - Severe allergic reaction: including rash, swelling, or anaphylaxis. - Stevens‑Johnson syndrome: extremely rare skin reaction.

Before prescribing Nitriderm Tts, clinicians should consider several safety measures.

Dose titration: start with the lowest patch strength and adjust based on response. Blood pressure monitoring: check for hypotension, especially when changing position. Concomitant nitrate therapy: avoid combined use to prevent additive vasodilation. Use with caution in patients with recent myocardial infarction or severe anemia. Avoid in patients with known hypersensitivity to organic nitrates. Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Nitriderm Tts can interact with several drug classes, requiring attention to avoid adverse events.

Major Interactions (Avoid): - Sildenafil and other PDE5 inhibitors: may cause profound hypotension. - Other organic nitrates: additive vasodilatory effect leading to severe blood pressure drop. - Antihypertensive agents (e.g., ACE inhibitors, beta‑blockers): may enhance blood pressure lowering.

Moderate Interactions (Monitor Closely): - Alcohol: can increase vasodilatory effect and dizziness. - Diuretics: may potentiate hypotensive response. - Certain antifungal agents (e.g., ketoconazole): may increase nitrate levels.
