Erectile dysfunction (ED) is the most common sexual dysfunction disorder in adult men, and with the aging of the population, the number of ED patients will continue to increase. “The emergence of Viagra has brought about a revolution in the treatment of ED patients. The commonly referred to “Viagra” is generally a type 5 phosphodiesterase (PDE5) inhibitor Viagra (sildenafil), and such drugs are also available in Silya (tadalafil) and Elidel (vardenafil). The second generation of PDE5 inhibitors, the efficacy of the drug can be maintained for 36 hours, can be called “long-acting Viagra”. The current treatment for ED is mostly on-demand PDE5 inhibitors, and the treatment is effective. The company’s main business is to provide a wide range of products and services to its customers. Is it possible to take a PDE5 inhibitor every day, just as you would for hypertension and diabetes? The answer is yes. Currently, there are different treatment options for ED for different groups of people. For older men, they can take Viagra before each sexual intercourse on an as-needed basis to complete their sex life. But for young adult male patients, you can use a long-term small dose of oral “long-acting Viagra” – cialis, which significantly improve the patient’s erectile function, and by improving the vascular endothelium and microcirculation, improve the penile vascular endothelial function, to promote erectile function again, to achieve the purpose of curing ED. The term “long-term” here refers to “off-demand” continuous use, generally greater than 2-3 months, while “low dose” refers to lower than the conventional recommended dose, mostly recommended 5mg daily Cialis. Therefore, a small daily dose of oral “long-acting Viagra” can improve erectile function and cure ED at the same time.
