Case sharing: Xiao Li is 30 years old, usually work pressure, often work late into the night, so that “waste sleep and forget sex”, the frequency and quality of sex life is significantly reduced. Some time ago, Xiao Li found some problems with sexual function, the morning erection is obviously reduced, the penis erection is not firm and not lasting, Xiao Li thought it might be because of the work is more tired, so did not take it seriously, went to the pharmacy to buy some kidney Chinese medicine to take, thinking that after a period of time should be improved. However, after a period of time, the erectile abnormalities did not improve, but on the contrary, there is a trend of aggravation, and even a complete inability to erect the situation. This is the first time I’ve ever been to a hospital. The doctor, after a detailed examination and questioning the medical history, judged that Xiao Li’s situation belongs to erectile dysfunction, which is often referred to as “impotence”. According to Xiao Li’s condition, once heard to take Western medicine, Xiao Li hurriedly said: I do not eat “Viagra”, everyone said Viagra is “aphrodisiac”, is “aphrodisiac”, not good for the body. Hearing this, the doctor hurriedly explained the mechanism of action of Viagra-type drugs to Xiao Li in detail, and under the doctor’s patient explanation Xiao Li finally dispelled his doubts and agreed to accept the doctor’s treatment plan. Half a month later, Xiao Li came to the follow-up, he told the doctor that the treatment effect is very obvious, said to continue to consolidate treatment. The doctor advised Xiao Li to adhere to the treatment for 3-6 months, and then slowly reduce the medication, and eventually stop it completely to achieve clinical cure. Even if you can’t stop the medication completely, you can still achieve the best condition with the minimum drug dose. To treat erectile dysfunction or not to take “Viagra” type drugs? “Viagra” at first refers to the United States Pfizer production of Viagra (sildenafil), later with the German company Bayer production of Elidel (vardenafil hydrochloride) and the United States Eli Lilly and Company production of cialis (tadalafil) joined, “Viagra” has become Viagra” has become a generic term for drugs used to treat erectile dysfunction. The chemical composition of these drugs is phosphodiesterase inhibitor type 5 (PDE5), which is very effective in the treatment of erectile dysfunction in men. However, in recent years, due to the lack of clinician guidance in the use of these drugs, resulting in excessive abuse; at the same time, under the propaganda of bad business, its side effects are over-exaggerated, making the “Viagra” is demonized, and even appear to talk about “Viagra” and change the situation. The situation. Patients should have a systematic and in-depth understanding of Viagra, neither indiscriminately abuse it, nor completely discard it because of choking. A, “Viagra” is not “aphrodisiac”, do not use it to “aphrodisiac” “Viagra” can treat male erectile It has been confirmed that Viagra can treat male erectile dysfunction and is clinically applicable to male patients who do have erectile dysfunction. However, although not all men have erectile dysfunction, but the fact that every man is interested in Viagra, this interest leads to many normal men in the process of sexual life often Viagra as an aphrodisiac, aphrodisiac to use. In fact, for normal men, Viagra plays a role in the process of action, and does not stimulate sexual desire, and can not extend the erection time, making erections more firm. The actual fact is that if a normal male abuses Viagra for a long time, without the guidance of a regular doctor, not only will he not improve his sexual function, but he will become psychologically dependent on Viagra, leading to interruptions or abnormal erection during the course of taking the drug. The phenomenon of abnormal function. The “addictiveness” of the drug is also known as drug dependence. The “addiction” of the drug, also known as drug dependence, refers to a state of dependence resulting from habitual intake of a certain drug, which can cause some special symptoms after withdrawal of the drug. There are two main types of dependence: psychiatric dependence and somatic dependence. Mental dependence refers to the patient’s special craving for a certain drug and the special psychological satisfaction after taking it; somatic dependence refers to the repeated administration of the same drug for many times, which causes some physiological or biochemical changes in the central nervous system and requires the continuous presence of a certain drug in the body, otherwise the drug addiction will produce withdrawal symptoms. On the one hand, by consulting the most authoritative medical database, there are no reports of Viagra addiction; on the other hand, through years of clinical observation and research, no patients have been found to be addicted after taking Viagra. Therefore, patients with erectile dysfunction need to be clear that taking Viagra will not produce addiction. Third, “Viagra” is not “poison”, the correct view of side effects At present, the side effects of “Viagra” drugs in some bad business malicious propaganda and people The “blackmail” spread, making many patients who are ready to receive “Viagra” drug treatment timid and discouraged. Any drug has side effects, and so does Viagra. “The most common adverse reactions to Viagra are headache, facial flushing, indigestion and muscle pain, nasal congestion, diarrhea, dizziness and rash, with a few patients experiencing temporary visual color changes (e.g., inability to distinguish between blue and green objects) and increased sensitivity of the eyes to light. Most of these symptoms are temporary and can be tolerated by the majority of patients after taking the drug for a period of time. The side effects of this drug can be considered acceptable when the patient’s condition needs to be treated with a particular drug, as long as the drug is chosen reasonably according to the patient’s condition. Many patients use Viagra as a one-time, temporary drug, believing that Viagra can only play the role of a temporary erection aid and cannot fundamentally change erectile function. Can not fundamentally change the erectile dysfunction, that is, the so-called “cure the symptoms not the root”. In fact, in recent years, a large number of studies have shown that adhering to long-term use of “Viagra” drugs can not only significantly improve the erectile condition of patients, improve the resulting anxiety, depression, eliminating the impact of psychological factors; and, long-term use of “Viagra” drugs can make the cavernous body long-term filling. The drugs can make the cavernous body congested for a long time, improve the blood supply and oxygen supply to the smooth muscle cells of the cavernous body, inhibit the atrophy of smooth muscle cells, maintain the ratio of muscle to fiber in the cavernous body, and inhibit the fibrosis of the cavernous body.
