The main class of drug for the treatment and management of Angina attack is what?

Nitroglycerin transdermal patches are used to prevent episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart).Nitroglycerin is a vasodilator that works by relaxing the blood vessels so that the heart does not need to work as hard and therefore does not need as much oxygen.However, if nitroglycerin is used continuously, the body may develop tolerance to its effects, meaning that it will not work as well to prevent angina attacks.Therefore, it is important to remove the patch at bedtime and apply a new one in the morning, leaving a 10-12 hour nitrate-free interval.This way, the body can restore its sensitivity to nitroglycerin and avoid angina episodes during the day.

Choice A is wrong because allergic response is not a common reason to remove the patch at night.Although some people may experience skin irritation or rash from the patch, this is usually mild and does not require discontinuation of the medication.If the skin reaction is severe or bothersome, the patch can be applied to a different area of the skin or switched to another form of nitroglycerin.

Choice C is wrong because overdose is unlikely to occur from using the patch as prescribed.Nitroglycerin patches come in doses ranging from 0.1 milligrams per hour to 0.8 mg/hr, and should be placed on clean, dry, and hairless skin for 12-14 hours and removed for 10-12 hours.If a patch loosens or falls off, it should be replaced with a fresh one.Overdose symptoms may include severe headache, dizziness, blurred vision, nausea, vomiting, sweating, chest pain, fast or irregular heartbeat, difficulty breathing, fainting, or seizures.If these occur, the patch should be removed immediately and medical attention should be sought.

Choice D is wrong because management of BPH (benign prostatic hyperplasia) is not related to nitroglycerin use.

BPH is a condition

ACE inhibitors are a type of medication used to treat high blood pressure and heart failure. They work by blocking the production of a hormone called angiotensin II, which narrows the blood vessels and increases blood pressure.By preventing this hormone from acting, ACE inhibitors lower blood pressure and reduce the workload on the heart. One of the most common side effects of ACE inhibitors is a dry cough, which occurs in 12–19% of people who take them. The cough is caused by the accumulation of a substance called bradykinin, which is normally broken down by angiotensin-converting enzyme (ACE).When ACE is inhibited, bradykinin levels increase and cause irritation and inflammation in the airways.

Choice A is wrong because decreased white blood cells are not a common side effect of ACE inhibitors.

However, some people may develop a condition called neutropenia, which is a low level of a type of white blood cell called neutrophils.This can increase the risk of infections and may require stopping the medication.

Choice B is wrong because swelling of the face and lips is not a common side effect of ACE inhibitors.

However, some people may develop a rare but serious allergic reaction called angioedema, which is a swelling of the deeper layers of the skin and mucous membranes.

This can affect the face, lips, tongue, throat, or other parts of the body and can cause difficulty breathing or swallowing.Angioedema can be life-threatening and requires immediate medical attention.

Choice D is wrong because renal failure is not a common side effect of ACE inhibitors.

However, some people may experience a decrease in kidney function or an increase in blood levels of creatinine, which is a waste product filtered by the kidneys.
