Which of the following anti-lipidemic drugs are the most potent antilipidemic agents, and have proven to lower the risk of Myocardial Infarction?
Atorvastatin.
Niacin.
Gemfibrozil
Amlodipine.
The Correct Answer is A
Atorvastatin is a type of statin, which are the most potent antilipidemic agents, and have proven to lower the risk of myocardial infarction by reducing the levels of low-density lipoprotein (LDL) cholesterol and triglycerides in the blood. Statins also slightly increase the level of high-density lipoprotein (HDL) cholesterol, which is beneficial for cardiovascular health.
Choice B, niacin, is a type of nicotinic acid, which can lower LDL cholesterol and triglycerides, and increase HDL cholesterol, but it is less effective than statins and has more side effects, such as flushing, itching, and liver toxicity.
Choice C, gemfibrozil, is a type of fibric acid derivative, which can lower triglycerides and increase HDL cholesterol, but have little effect on LDL cholesterol. They are mainly used for patients with high triglyceride levels or low HDL cholesterol levels.
Choice D, amlodipine, is not an antilipidemic agent at all. It is a type of calcium channel blocker, which is used to treat hypertension and angina by relaxing the blood vessels and reducing the workload of the heart.

Correct Answer is A
Explanation
Lisinopril belongs to the class of drugs calledangiotensin-converting enzyme (ACE) inhibitors.ACE inhibitors work by blocking the enzyme that converts angiotensin I to angiotensin II, a hormone that causes blood vessels to narrow and raise blood pressure.By inhibiting this enzyme, ACE inhibitors relax and widen the blood vessels, lower blood pressure, and improve blood flow to the heart and kidneys.
Choice B.Candesartan is wrong because it belongs to the class of drugs calledangiotensin II receptor blockers (ARBs).ARBs work by blocking the action of angiotensin II on its receptors, preventing it from causing blood vessel constriction and high blood pressure.ARBs are similar to ACE inhibitors in their effects, but they do not affect the enzyme or the level of bradykinin, a peptide that can cause cough and angioedema as side effects of ACE inhibitors.
Choice C.Metoprolol is wrong because it belongs to the class of drugs calledbeta blockers.Beta blockers work by blocking the effects of adrenaline and other hormones that stimulate the heart and blood vessels, causing them to beat slower and with less force.Beta blockers lower blood pressure and reduce the workload on the heart.
Choice D.Amlodipine is wrong because it belongs to the class of drugs calledcalcium channel blockers.Calcium channel blockers work by blocking the entry of calcium into the muscle cells of the heart and blood vessels, causing them to relax and dilate.Calcium channel blockers lower blood pressure and improve blood flow to the heart.
Normal ranges for blood pressure vary depending on age, gender, and other factors, but generally, a systolic blood pressure (the top number) of less than 120 mmHg and a diastolic blood pressure (the bottom number) of less than 80 mmHg are considered normal for adults.A blood pressure of 130/80 mmHg or higher is considered high and may require treatment with medication.
Correct Answer is C
Explanation
Anticoagulants are medicines that increase the time it takes for blood to clot.They do not dissolve existing clots, but they can stop them from getting bigger or prevent new clots from forming.Anticoagulants work by interfering with different steps of the blood coagulation pathway, which is a complex process that involves many clotting factors.
Choice A is wrong because anticoagulants do not dissolve existing clots.To dissolve clots, you need medicines called thrombolytics or fibrinolytics, which break down the fibrin that holds the clots together.
Choice B is wrong because anticoagulants do not transport platelets.
Platelets are blood cells that help with clotting by sticking together and forming a plug at the site of an injury.Anticoagulants may affect the function of platelets, but they do not move them around.
Choice D is wrong because anticoagulants do not increase blood viscosity.
Viscosity is a measure of how thick and sticky a fluid is.
Anticoagulants are sometimes called blood thinners, but they do not actually change the viscosity of blood.They just make it less likely to clot.
Normal ranges for blood clotting tests vary depending on the type of test and the laboratory that performs it.
Some common tests and their normal ranges are:
• Prothrombin time (PT): 11 to 13.5 seconds
• International normalized ratio (INR): 0.8 to 1.2
• Activated partial thromboplastin time (aPTT): 25 to 35 seconds
• Anti-factor Xa: 0.3 to 0.7 units/mL
• D-dimer: less than 0.5 mcg/mL
