Are nitrates antianginal?
Organic nitrates are potent vasodilators and are the most widely used antianginal agents during acute events. They selectively dilate epicardial coronaries and also enhance collateral flow; they also inhibit platelet aggregation.
Which of the following is the nitrates as antianginal drug?
List of Antianginal agents:

| Rectiv (Pro) Generic name: nitroglycerin | 6.7 | 24 reviews |
| Imdur (Pro) Generic name: isosorbide mononitrate | 6.5 | 18 reviews |
| Nitro-Bid (Pro) Generic name: nitroglycerin | 9.0 | 5 reviews |

What type of drugs are nitrates?
Medicines that contain organic nitrates include:
- Nitroglycerin (such as Nitro-Dur, Nitrolingual, Nitrostat).
- Isosorbide (such as Dilatrate, Isordil).
- Nitroprusside (such as Nitropress).
- Amyl nitrite or amyl nitrate. These are sometimes called “poppers.” They are sometimes abused.
What are antianginal drugs used for?
Antianginal drugs are used to provide immediate relief from symptoms and prevent angina attacks. If your risk of having a heart attack or stroke is high, it should be possible to reduce the risk by using a combination of medication and lifestyle changes.
Why is nitrate used in angina?
Nitrates improve blood flow by relaxing and dilating (expanding) veins and arteries, including the coronary arteries. They reduce the amount of blood returning to the heart, which may be helpful for patients with heart failure.
Why are nitrates used in angina pectoris?
Nitrates work as venodilators and arterial dilators, and by these actions in patients with angina pectoris can reduce myocardial oxygen demands while maintaining or increasing coronary artery flow. On the cellular level, they may increase endothelial prostacyclin release to cause their vasodilating effects.
Is amlodipine an antianginal?
In comparison with other antianginal drugs, once-daily amlodipine at a dosage range of 5-10 mg demonstrated antianginal activity comparable to thrice-daily diltiazem and once-daily nadolol.
Is Amlodipine a nitrate medication?
Amlodipine has a long duration of action (plasma half-life is 30–50h), a very good trough-to-peak ratio, and it can be given once daily [2, 18].
Is hydralazine a nitrate?
Pharmacologic action. With proper dose selection, the hydralazine-nitrate combination provides balanced afterload-preload reduction with a lowering of ventricular filling pressure, and systemic and pulmonic vascular resistance.
What are nitrates pharmacology?
Nitrates are medications that come under the umbrella of a larger group called vasodilators, which dilate the walls of blood vessels. Nitrates are primarily used to treat angina pectoris, which is pain caused by reduced blood flow to the heart muscle; as well as hypertension, and heart failure.
