Nitrostat
What is Nitrostat?
Nitrostat is a type of medicine known as an organic nitrate and is a vasodilating agent. It is used to treat a type of chest pain called angina.
Description
Nitrostat is a stabilized sublingual compressed nitroglycerin tablet that contains 0.3 mg, 0.4 mg , or 0.6 mg nitroglycerin; as well as lactose monohydrate, NF; glyceryl monostearate, NF; pregelatinized starch, NF; calcium stearate, NF powder; and silicon dioxide, colloidal, NF.
Nitroglycerin, an organic nitrate, is a vasodilating agent. The chemical name for nitroglycerin is 1, 2, 3 propanetriol trinitrate and the chemical structure is:
Mechanism of Action
Nitroglycerin forms free radical nitric oxide (NO) which activates guanylate cyclase, resulting in an increase of guanosine 3’5′ monophosphate (cyclic GMP) in smooth muscle and other tissues. These events lead to dephosphorylation of myosin light chains, which regulate the contractile state in smooth muscle, and result in vasodilatation.
What is Angina?
Who should not take Nitrostat?
Do not use Nitrostat if you are allergic to organic nitrates (like the active ingredient in Nitrostat).
You should not take Nitrostat if you have the following conditions:
- very recent heart attack
- severe anemia
- increased pressure in the head
Do not take Nitrostat with drugs for erectile dysfunction, like Viagra (sildenafil citrate), Cialis (tadalafil), or Levitra (vardenafil hydrochloride), as this may lead to extreme lowering of your blood pressure.
Do not take Nitrostat if you take medicines called guanylate cyclase stimulators which include riociguat, a medicine that treats pulmonary arterial hypertension and chronic-thromboembolic pulmonary hypertension.
What should I tell my healthcare provider before taking Nitrostat?
Before using Nitrostat, tell your doctor if:
- You are taking any medicines that are used to treat angina, heart failure, or an irregular heartbeat.
- You are taking any medicines that reduce blood pressure.
- You are taking any diuretics (water pills).
- You are taking medicines that can cause dry mouth such as tricyclic antidepressants (e.g. amitriptyline, desipramine, doxepin), anticholinergic drugs, or any antimuscarinic drugs (e.g. atropine).

How should I take Nitrostat?

- One tablet should be dissolved under the tongue or in the oral cavity at the first sign of chest pain.
- The dose may be repeated approximately every 5 minutes, until the chest pain is relieved.
- If the pain persists after a total of 3 tablets in a 15-minute period, or is different than you typically experience, call your doctor or seek emergency help.
- Nitrostat may be used 5 to 10 minutes prior to activities that might cause chest pain.
- You may feel a burning or tingling sensation in your mouth when you take Nitrostat.
What should I avoid while taking Nitrostat?
- Do not breastfeed. It is not known if Nitrostat will pass through your milk.
- Do not consume alcohol while taking Nitrostat, as this can lower your blood pressure.
- Do not start any new prescription or non-prescription medicines or supplements, unless you check with your doctor first.
