Conclusion: calcium channel blockers can relax vascular smooth muscle, reduce myocardial contractility, reduce myocardial oxygen consumption, and improve myocardial blood supply.
The harm of hypertension lies in the fact that hypertension is not a serious complication in the elderly. So most patients with hypertension are actively taking medicine to control blood pressure, but there are still some people worried about taking hypertension drugs, after all, drugs have side effects.
At the age of 50, 71-year-old Uncle Zhang found high blood pressure, which is not a big age. After all, there are too many people of the same age with high blood pressure. Because Uncle Zhang had a strong personality, he was never afraid of these minor diseases, so when the doctor prescribed the medicine, he resolutely refused, and for this reason, he also had a prejudice against the hospital. He thinks that if he goes to the hospital, he will be prescribed medicine, and so many drugs will be prescribed, and people will be treated as medicine boxes, so he thinks this hospital is not good.
They don't know how to reduce their blood pressure by prescribing a lot of drugs in the hospital. Unfortunately, Uncle Zhang came to see a doctor when he had moderate to severe hypertension, how could he not prescribe medicine?
Why did Uncle Zhang become a supporter of taking medicine?
If you don't take medicine, you won't be punished immediately. Uncle Zhang still goes his own way. His life is rich and colorful. But the outbreak of high blood pressure didn't take him long. Three years later, after a party, Uncle Zhang suddenly suffered from a cerebral hemorrhage and fell to the ground. Originally, the ocean of joy suddenly became a tense rescue field. Unfortunately, there were no health care workers for the people at these gatherings, and there was no other way except to fight 120.
Fortunately, after timely treatment, Uncle Zhang saved his life. The doctor said that he would die in this situation! After the great disaster of life and death, Uncle Zhang seems to have completely changed. He was no longer keen on drinking and eating meat, and his mental state became very calm. He doesn't go to friends' parties anymore, and he likes to keep fit at home.
Because of this cerebral hemorrhage! Cerebral hemorrhage is the primary nontraumatic intracerebral hemorrhage, also known as a hemorrhagic stroke. The common causes include hypertension, aneurysm, blood disease, anticoagulant or thrombolytic therapy, moyamoya disease, and so on. The inducements include strenuous exercise, a full meal, drinking, and defecation. Obviously, Uncle Zhang's party was induced by drinking and having a good meal, while high blood pressure was a long-term cause.
After this, Uncle Zhang has always put the control of high blood pressure as the top priority. Just don't take medicine! Compared to the experience of life and death in a hospital, taking medicine is too small. Therefore, Uncle Zhang often advises the patients with high blood pressure to take medicine on time, otherwise, he is a lesson from the past. I just didn't expect that I took the medicine for 18 years, and the time will continue to extend.
What does Zhang Shuyao take?
After Uncle Zhang was discharged from the hospital, the antihypertensive drug prescribed by the doctor was divine, i.e. nifedipine sustained-release tablets. It is a calcium channel blocker, which can inhibit extracellular calcium influx and reduce intracellular calcium concentration. Calcium channel blockers can be divided into selective and nonselective drugs. Selective calcium channel blockers include dihydropyridines and nondihydropyridines. Dihydropyridines are the most widely used drugs, such as nifedipine, amlodipine, felodipine, nicardipine, and Levamlodipine.
High blood pressure does not take medicine consequence
Calcium channel blockers can relax vascular smooth muscle, reduce myocardial contractility, reduce myocardial oxygen consumption, and improve myocardial blood supply. As a first-line antihypertensive drug, this kind of drug is popular with patients. Similarly, in a large number of clinical trials completed in China, based on calcium channel blockers, the results show that these drugs can significantly reduce the risk of stroke in patients with hypertension. According to the intensity of antihypertensive drugs in the prevention of stroke, they were calcium channel blockers, diuretics, renin-angiotensin system inhibitors, and beta-blockers.
Calcium channel blockers can be used as basic drugs for other types of hypertension, especially for elderly patients with hypertension, simple systolic hypertension, coronary or carotid atherosclerosis, and peripheral vascular disease.
Of course, as mentioned at the beginning of the article, drugs do have side effects, and calcium channel blockers are no exception. The main side effects of these drugs are heart failure, hypotension, facial flushing, edema of lower limbs and ankles, gingival hyperplasia, etc.
