After suffering from high blood pressure, many patients need to take antihypertensive drugs to stabilize their blood pressure. Moreover, they need to take these drugs for a long time and do not dare to stop them casually.
But we also know that as the saying goes, "medicines are three parts poisonous." Taking medicine regularly can easily damage the liver, because most medicines are metabolized by the liver.
But if you don’t take medicine and your blood pressure is not controlled, it will cause a series of cardiovascular and cerebrovascular diseases, which are even more dangerous. Therefore, no matter how worried you are about the side effects, you still have to take this medicine.
Only by choosing an antihypertensive drug that suits you can reduce the harm caused by side effects. Currently, there are more than 40 commonly used antihypertensive drugs on the market. Each drug has different dosage, side effects, and contraindications. Do you know how to choose?
Nifedipine is a classic old drug among calcium channel blockers. It has also been the first choice antihypertensive drug for many patients with hypertension and is very common in life. Including nifedipine, amlodipine, levamlodipine, etc.
Dipine antihypertensive drugs lower blood pressure by preventing calcium ions from entering myocardial cells and vascular smooth muscle cells, because the contraction of the heart and blood vessels requires the participation of calcium ions. When calcium ions are reduced, blood pressure can be lowered.
Precautions:
Side effects:
Common usage and dosage of dipine drugs are as follows:
Sartan drugs can disguise themselves as blood vessels Tensin binds to receptors on vascular smooth muscle cells, preventing the true angiotensin from functioning, preventing vasoconstriction, and achieving the effect of lowering blood pressure.
Precautions:
Side effects:
The common usage and dosage of Sartan drugs are as follows:
The synthesis of angiotensin II in the body requires An enzyme is involved, and antihypertensive drugs such as pruritanone can directly hinder the function of this enzyme. When angiotensin is reduced, blood vessels will contract less, thereby lowering blood pressure.
Precautions:
Side effects:
Common usage and dosage of sartan drugs are as follows:
Works by blocking beta receptors To lower blood pressure, so they are called beta-blockers.
In situations of tension, high psychological pressure, etc., the sympathetic nerves are excited, the heart rate is fast, and the blood pressure is easy to rise. Sympathetic innervation of the myocardium requires an intermediary beta receptor. Beta blockers can prevent it from functioning, thereby lowering the heart rate, thereby reducing cardiac output and blood pressure.
Precautions:
Side effects:
Common beta blocker usage and dosage are as follows:
Diuretics can reduce blood pressure in the blood system blood volume in. If there is too much water and sodium retention in the body and the blood volume exceeds the reservoir capacity, the blood pressure will naturally rise. Diuretics reduce blood pressure by increasing excretion.
Precautions:
Side effects:
Common diuretic usage and dosage are as follows:
When single drug control is not good, combination is often needed Take a variety of antihypertensive drugs. Combination preparations containing multiple single drugs are available on the market.
Note: Compound preparations each contain different single drugs. Patients who cannot use a certain single drug cannot use compound preparations containing this single drug.
Side effects: Each compound preparation contains a different single drug, and the side effects of a certain single drug will also appear in the compound preparation containing the single drug.
Common compound preparation usage and dosage are as follows:
