Hypertension Drug Selection and Antioxidant Protection: Analyzing the Efficacy of Five Classes of Antihypertensive Drugs, Free Radical Harm, and Cardiotonic Foods [i]

If your blood pressure remains high despite lifestyle changes, you will need to take antihypertensive medication. However, it's important to understand that medication cannot cure hypertension or its underlying cause; it only relieves the symptoms and cannot completely restore your health. If a pilot's license is revoked due to high blood pressure, they cannot regain it. Even if their blood pressure returns to normal, but tests prove it was due to medication, they still cannot regain their license. Generally speaking, there are five categories of medications for treating hypertension with different effects. Pharmaceutical companies produce similar or identical drugs and sell them under different brand names, resulting in approximately 60 different medications available for controlling hypertension. What are some medications for treating hypertension? 1. Diuretics: These drugs excrete excess salt and fluid from the body, reducing blood volume and lowering pressure on blood vessels. Diuretics are further divided into thiazide diuretics, thiazide diuretics, and potassium-containing diuretics. Each drug only partially affects the kidneys. Because these drugs absorb minerals from the body, potassium supplements or potassium-containing medications are needed while taking them. 2. Beta-blockers: Act on adrenaline. Reduce the burden on the heart and slow the heartbeat. 3. Alpha-blockers: Inhibit certain receptors in the blood vessel walls, reduce vascular load, and lower blood pressure. 4. Calcium receptor blockers: Reduce pressure on blood vessel walls, lower blood pressure, and reduce the workload on the heart. They can also relieve stress on myocardial cells and reduce the heart's oxygen demand. 5. ACE inhibitors and angiotensin-I receptor agonists: Dilate blood vessels, lower blood pressure, and inhibit a vasoconstrictor hormone, thereby reducing the burden on the heart. Antioxidants-strengthening agents for the heart and blood circulation. It is currently believed that arteriosclerosis, certain cancers, the aging process, rheumatism, and our body's self-recovery mechanisms after injury can all benefit from antioxidants because they are hunters of free radicals. Free radicals are enemies of cells, and antioxidants can protect your organ function. Antioxidants are substances we are constantly exposed to. We absorb them daily through our diet, but the intake is still insufficient. For example, beta-carotene, vitamin C, and vitamin E, trace elements such as selenium, and various secondary plant matter are among the most common and strongest antioxidants. Here are some excellent foods containing antioxidants: Vitamin E: wheat germ, grains, asparagus, spinach, sweet potatoes. Vitamin C: lemons, tomatoes, strawberries, Brussels sprouts, raw bell peppers. Beta-carotene: pumpkin, carrots, broccoli, chard, sweet potatoes. Selenium: whole grains, malt, brewer's yeast, fresh fruits, fresh vegetables. You can take the following test to determine if you should increase your intake of antioxidants: 1. Is my cholesterol too high? 2. Do I smoke or frequently live with someone who smokes? 3. Do I take medication regularly? 4. Do I work under lights for several hours every day? 5. Is there a magnetic field in my work environment? 6. Do I exercise seriously for several hours almost every day? If your answer to any of these questions is "yes," then you should increase your intake of antioxidants. The more "correct" answers you get, the more of these antioxidants your body needs to maintain the normal function of your organs. [i]
