In the recently popular TV series "The Story of Rose", Fu Jiaming, who is elegant and artistic, invited Huang Yimei to eat noodles at home, but Huang Yimei saw him taking sildenafil citrate tablets (commonly known as "Viagra"). , Huang Yimei was so frightened that the "male god" filter instantly shattered. It wasn't until Fu Jiaming found her and explained that the medicine was to treat heart disease that the misunderstanding was resolved, and the relationship between the two further progressed.
Having said that, there is a lot of work pressure nowadays. After a certain age, many men's "those" functions will decline significantly. In addition, they have been facing huge pressure in life and work for a long time, smoking, drinking, staying up late and other bad habits, resulting in The incidence of erectile dysfunction (ed) in men is increasing.
"Viagra" is the drug of choice for many men with this disorder. What is "Viagra"? Is it really that magical?
"Viagra" is the transliteration of English viagra and also the commercial name of sildenafil citrate. Sildenafil citrate tablets were first developed to treat cardiovascular diseases such as angina pectoris. During clinical trials, some elderly male subjects reported that taking the drug had some help with male sexual dysfunction. Therefore, the researchers divided their work into two parts. One part continued to study the application of sildenafil citrate tablets in cardiovascular diseases, and the other part carried out clinical trials for the treatment of male erectile dysfunction.
According to current epidemiological studies, approximately 10% of men aged 40-70 years worldwide suffer from severe or complete erectile dysfunction. At present, "Viagra" drugs generally include Viagra, Levitra, Cialis, etc., which are prescription drugs.
Medicine is a good medicine, but you must follow your doctor's advice.
It is worth noting that many men now naturally think of taking "Viagra" as soon as they discover that they have suspected symptoms of erectile dysfunction (ED). This is incorrect.
Huang Yasheng, director of the Urology Department of Hangzhou Hospital of Traditional Chinese Medicine, reminded that medicine is a good medicine, but you must pay attention to the dosage, take it strictly according to the instructions, and do not take too much. Overdosing will not make you stronger, but may increase or worsen adverse reactions, such as headaches, palpitations, hypotension, etc.
Huang Yasheng reminded that there are many causes of male erectile dysfunction and they are also very complicated. "Viagra" is not a panacea for treating this disease. For example, if there are lesions in the corpus cavernosum itself, and the nerves that control erections are damaged, these situations require oral administration of "Viagra". it is invalid. Therefore, once suspected symptoms appear, you should still go to the men's department of a regular hospital for treatment under the guidance of a doctor, and do not act "rashly".
It has been included in the national centralized procurement many times, and it is not a medical insurance product.
In the play, Fu Jiaming said that sildenafil citrate has been included in the national medical insurance. But in fact, sildenafil citrate is not currently included in the medical insurance catalog, but is included in the national centralized procurement list.
The inclusion of drugs in medical insurance and centralized procurement are two different concepts. In layman’s terms, entering medical insurance means that a drug enters the medical insurance catalog, which affects whether it can enter the scope of reimbursement; entering centralized procurement means that a drug enters the scope of national drug centralized bulk procurement, which affects whether its price will be reduced. There is no necessary connection between the two.
Since its development, sildenafil has suffered from angina pectoris, erectile dysfunction, and pulmonary hypertension. However, some recent studies also suggest that sildenafil does more.
In recent years, some scholars have studied the application of sildenafil in the field of assisted reproduction. The research suggests that sildenafil can improve the thickness, shape and blood flow of the endometrium, thereby increasing the success rate of embryo implantation. However, the clinical application of this drug is still controversial.
Sildenafil has been on the market for 20 years. Research and exploration on it have never stopped in the past 20 years. In recent years, studies have found that as a selective pde5 inhibitor, it can play a role in the cardiovascular system, genitourinary system, respiratory system, vision, nervous system, etc., and can produce anti- tumor effects.
After 6 years of follow-up, researchers from the Cleveland Clinic in the United States found that people who took sildenafil were 69% less likely to develop Alzheimer's disease. These findings also expand the application scope of sildenafil citrate, but more large-sample studies are still needed to confirm.
People in these three categories should pay attention to avoid using
Sildenafil is not an aphrodisiac. When taking this type of drug, you must strictly follow the doctor's instructions. Do not take it blindly, otherwise there will be more serious side effects.
Doctors remind that the following three groups of people may have serious side effects when using sildefin, and it is recommended to avoid taking it.
1. Patients with coronary heart disease
Patients with coronary heart disease need to pay special attention to avoid using "Viagra". The simultaneous use of Viagra and nitrate drugs (such as nitroglycerin, isosorbide dinitrate, etc.) may cause a sudden drop in blood pressure, so patients with coronary heart disease must consult a doctor before using Viagra.
2. People who drink alcohol for a long time
Alcohol will dilate blood vessels to a certain extent, and the blood vessel dilation effect caused by sildenafil will lead to excessive intravascular blood flow and increase the probability of acute cardiovascular disease. Therefore, people who drink alcohol for a long time or after drinking alcohol cannot take Viagra.
3. Hypertensive people
Hypertensive patients need to be particularly careful when using Viagra. "Viagra" will enhance the effect of most antihypertensive drugs, such as amlodipine, nifedipine, hydrochlorothiazide, valsartan, and candesartan , benazepril, etc.
In addition, some patients with high blood pressure may be taking medications such as alpha-receptor antagonists, and the simultaneous use of these drugs with Viagra may cause blood pressure fluctuations. It is not recommended to take "Viagra" four hours before and after taking antihypertensive drugs.
