The video provides a concise nursing‑focused review of nitroglycerin. It begins by listing the generic name, common trade names, pharmacologic class (nitrate) and therapeutic class (anti‑anginal). Indications are explained, emphasizing its use for acute angina, myocardial infarction, and heart failure, as well as long‑term prevention. The mechanism of action is described: nitroglycerin is converted to nitric oxide, leading to smooth‑muscle relaxation, coronary vasodilation, increased myocardial blood flow, and relief of ischemic pain. Therapeutic effects include pain relief, increased cardiac output, and lowered blood pressure. Common adverse effects such as dizziness, headache, blurred vision, hypotension, syncope, tachycardia, and GI upset are outlined with their physiologic basis. Nursing assessment priorities are highlighted: frequent monitoring of blood pressure, heart rate, and continuous ECG for IV administration. Major contraindications (e.g., increased intracranial pressure, severe anemia, pericardial tamponade, hypovolemia, glaucoma) are listed. Patient education points cover correct dosing timing, positioning to avoid orthostatic hypotension, avoidance of alcohol, storage in airtight light‑blocking containers, and instructions for sublingual, oral, and transdermal routes, including when to repeat doses and when to seek emergency care. The video concludes with promotional messages for additional nursing resources.

In this video you'll learn the side effects of nitroglycerin and Nitroglycerin's mechanism of Action. Now friends, I know, I know pharmacology can be challenging to learn in nursing school. So we are going to break it down super simple for you step by step so that you can finally understand it. So don't worry, you don't need to figure everything out alone anymore for nursing school. We are here to help you out every single day step of the way.

All right, let's talk about nitroglycerin, the generic name nitroglycerin and the trade names Nitrobid Go Nitro, Nitro Time, Nitromist, Natrostat and Natro Lingual. The pharmacologic class is a nitrate and the therapeutic class is an anti anginal. The indications for nitroglycerin or what it is used for is that it depends on the root and there are many different uses depending on this root. It's most commonly used to help manage angina pectoris, heart attacks or myocardial infarctions and heart failure. Nitroglycerin can also be used for an acute episode of angina and for long term prevention. The mechanism of action of nitroglycerin is that it's converted to nitric oxide which then is converted to a protein that causes smooth muscle relaxation which then causes vasodilation. This dilates the coronary arteries, increasing the blood flow to the heart. This increase in the blood flow helps the ischemic areas which relieves the pain associated with angina pectoris. The therapeutic effect of all of this is that by increasing the blood flow to the heart, it relieves the symptoms and pain associated with the angina pectoris from ischemia. It also helps to prevent future angina attacks and there is an increased cardiac output and reduction of blood pressure from the vasodilation. Some side effects of nitroglycerin can be dizziness, headache and blurred vision which can occur because of hypotension that happens with vasodilation. Due to that smooth muscle relaxation, hypotension, syncope and tachycardia can all happen as well due to that smooth muscle relaxation causing a decrease in blood pressure, so the heart tries to increase the heart rate in order to compensate. GI upset can occur due to the dizziness and hypotension that happens when the vessels dilate. For your nursing assessment on a patient taking nitroglycerin, you're going to want to monitor their blood pressure closely as well as their heart rate. If the patient is receiving IV nitroglycerin, they should be on a continuous ECG monitor to monitor for any arrhythmias. Major contraindications for taking nitroglycerin are increased intracranial pressure, severe anemia, pericardial tamponade, pericarditis, hypovolemia and glaucoma. With Patient education if your patient is taking nitroglycerin, you're going to want to have them take it exactly as prescribed. You're going to want to encourage them to change positions slowly because dizziness may occur due to that orthostatic hypotension. They should avoid alcohol and the medication should be used at the first sign of an angina attack. Relief usually happens within 5 minutes, but a second dose can be given at the 5 to 10 mark. If the first dose does not relieve the pain, you should not use more than three doses and if three doses are needed without relief, the patient should go to the emergency department for further medical care. The medication should be stored in an airtight and light blocking container to ensure the medication retains its effectiveness for nursing. Considerations with nitroglycerin, you're going to want to make sure that the subliginal tablet should be held under the tongue until it is fully dissolved. The mouth should not be rinsed out for at least five minutes to make sure the entire medication is absorbed. The PO form should be taken one hour before or two hours after meals for the best absorption. Relief from the sublingual, missed or transdermal roots used usually happens within five minutes. If it hasn't happened within five minutes, a second dose can be given in the five to ten minute mark. And if the first dose hasn't relieved the pain, do not give more than three doses.
