Information about Nitro-BID (Nitroglycerin TR)
Nitro-BID is a brand name for nitroglycerin transdermal system (TR), a topical patch used to prevent and relieve angina (chest pain) caused by coronary artery disease. It works by relaxing and dilating blood vessels, improving blood flow to the heart, and reducing the heart's workload.
Product Highlights
- Used to prevent angina episodes in patients with chronic stable angina or angina due to coronary artery disease.
- Primarily prescribed for the long-term management of angina rather than acute relief.
Key Ingredient
Key Benefits
- Helps prevent chest pain by improving blood flow to the heart.
- The transdermal patch provides a continuous release of medication over a 24-hour period.
- Applied once daily, offering ease of use compared to oral medications.
Direction of Use
- Apply one patch to a clean, dry, and hairless area of the skin, typically on the chest or upper arm, once daily.
- Each patch is worn for 12 to 14 hours, followed by a 10–12 hour patch-free interval to prevent tolerance.
- Rotate application sites to avoid skin irritation.
Safety Concerns
- Common side effect due to vasodilation.
- Risk of low blood pressure, especially if combined with other blood pressure-lowering medications.
- May cause dizziness upon standing (orthostatic hypotension).
- Extended use may lead to tolerance, reducing effectiveness; patches should be removed periodically to minimize this.
Avoid Nitro-BID (Nitroglycerin TR) If
- Avoid if you have a known hypersensitivity to nitroglycerin or similar compounds.
- Do not use if you have severe anemia or hypotension, as it may worsen these conditions.
- Avoid use if you have recently had a heart attack, stroke, or other significant cardiovascular events, unless under medical supervision.
- Avoid if using phosphodiesterase inhibitors (e.g., sildenafil, tadalafil) due to the risk of severe hypotension.
