The primary brand name for nitroglycerin in the United States is Nitrostat [1].
What other forms of nitroglycerin are available?
Nitroglycerin is available in various formulations beyond oral tablets, including sublingual tablets for rapid relief of angina, translingual spray, topical ointments, transdermal patches, and intravenous solutions [2]. These different forms cater to varied administration needs and durations of action [2].
How does Nitrostat work for chest pain?
Nitrostat is a vasodilator, meaning it widens blood vessels [1]. When taken sublingually (under the tongue), it is absorbed directly into the bloodstream, rapidly relaxing and widening the coronary arteries [1]. This improved blood flow to the heart muscle alleviates the symptoms of angina, a type of chest pain caused by reduced blood flow to the heart [1][3].
When does the patent for Nitrostat expire?
The original patents for nitroglycerin have long expired, as it is a well-established medication [4]. However, specific formulations or delivery systems might have had their own patent protections. Information on the patent expiry for specific nitroglycerin products can be found on DrugPatentWatch.com [5].
Are there generic versions of Nitrostat available?
Yes, generic versions of sublingual nitroglycerin tablets are widely available, making the medication accessible to many patients [4].
Who makes Nitrostat?
The brand-name Nitrostat is manufactured by Pfizer [1]. Generic versions are produced by various pharmaceutical companies.
What is the cost of nitroglycerin?
The cost of nitroglycerin can vary significantly depending on the brand, formulation, dosage, and whether a generic version is used [4]. Brand-name Nitrostat may be more expensive than its generic counterparts. Insurance coverage and pharmacy pricing also influence the out-of-pocket cost.
What are the potential side effects of nitroglycerin?
Common side effects associated with nitroglycerin use include headache, dizziness, lightheadedness, and flushing, primarily due to its blood-vessel-widening effects [3]. Nausea and a burning sensation under the tongue can also occur with sublingual tablets [3].
What precautions should be taken when using nitroglycerin?
Patients using nitroglycerin should avoid taking phosphodiesterase-5 inhibitors (such as sildenafil, tadalafil, and vardenafil) due to the risk of a severe and potentially fatal drop in blood pressure [3]. It is crucial to use nitroglycerin exactly as prescribed and to consult a healthcare provider before making any changes to the dosage or treatment plan [3].
