The main class of drug for the treatment and management of Angina attack is what?
Fatty oxidase enzyme inhibitors.
Beta adrenergic blockers.
Nitrates.
Statins.
The Correct Answer is C
Nitrates are a class of drugs that help to widen the blood vessels and increase blood flow to the heart muscle, which reduces the chest pain or discomfort caused by angina. Nitrates can be taken as a mouth spray or tablets that dissolve under the tongue during an angina attack, or as a preventive measure before physical activity.
Choice A is wrong because fatty oxidase enzyme inhibitors are not a real class of drugs.
Fatty acid oxidation is a process that breaks down fats for energy, and it is not related to angina treatment.
Choice B is wrong because beta adrenergic blockers are not the main class of drugs for angina treatment, although they can be used to prevent angina attacks by slowing down the heart rate and reducing the blood pressure.
Beta blockers block the effects of epinephrine (adrenaline) on the heart and blood vessels, which reduces the oxygen demand of the heart.
Choice D is wrong because statins are not used to treat angina attacks, but to lower the cholesterol levels in the blood and prevent plaque buildup in the arteries.
Statins can help reduce the risk of heart attacks and strokes in people with angina, but they do not relieve angina symptoms.

Correct Answer is D
Explanation
Taking niacin with an NSAID such as ibuprofen can reduce flushing, the most common adverse effect of niacin therapy. Flushing is a side effect of taking large doses of niacin (vitamin B3) supplements.It happens when the niacin causes the small blood vessels in your skin to dilate so more blood can rush through.Flushing can cause skin redness, warmth, itching, tingling, or burning sensations.
Choice A is wrong because taking niacin before starting daily activities can increase the risk of flushing and interfere with your routine.Flushing usually occurs within 15 to 30 minutes of taking niacin and lasts for about an hour.
Choice B is wrong because taking niacin with a sedative can increase the risk of liver damage, especially if the sedative is acetaminophen (Tylenol).Niacin can also cause liver problems at high doses, so combining it with another liver-toxic drug is not advisable.
Choice C is wrong because taking niacin with grapefruit juice can increase the risk of side effects, such as low blood pressure, dizziness, or fainting.Grapefruit juice can interfere with the metabolism of some drugs, including niacin, and make them more potent or toxic.
Normal ranges for niacin intake vary depending on age and gender.The recommended dietary allowance (RDA) for adult males is 16 mg per day and for adult females is 14 mg per day.Higher doses of niacin may be prescribed by a doctor to treat high cholesterol or other conditions, but they should be taken under medical supervision and with caution.
Correct Answer is D
Explanation
Nitroglycerin sublingual is a medication that is used to treat chest pain or angina by relaxing the blood vessels and reducing the oxygen demand of the heart.A common side effect of nitroglycerin sublingual is headache, which may be severe and throbbing.Headache is often a sign that the medication is working.Other possible side effects include flushing, dizziness, lightheadedness, nausea, vomiting, fast heart rate, numbness, tingling, burning pain, rash, hives, sweating, pale skin, difficulty breathing and allergic reaction.
Choice A is wrong because nausea is not the most common adverse effect of nitroglycerin sublingual.Nausea may occur in some people, but it is usually mild and transient.
Choice B is wrong because bradycardia (slow heart rate) is not a common adverse effect of nitroglycerin sublingual.Nitroglycerin sublingual may cause tachycardia (fast heart rate) in some people as a result of vasodilation and reflex stimulation of the heart.
Choice C is wrong because hypertension (high blood pressure) is not a common adverse effect of nitroglycerin sublingual.Nitroglycerin sublingual may cause hypotension (low blood pressure) in some people due to its vasodilating action.Hypotension may lead to lightheadedness, fainting or shock in severe cases.
The normal range for blood pressure is less than 120/80 mmHg for adults.
The normal range for heart rate is 60 to 100 beats per minute for adults.
