Sildenafil acts directly on blood vessels and cannot induce or increase desire, let alone improve "combat effectiveness", so it cannot aphrodisiac and will only work under sexual stimulation. In addition, although sildenafil is not addictive pharmacologically, it may cause psychological dependence. In 2014, the patent protection of Pfizer's blue pill, "Viagra", expired, and many generic drugs quickly appeared in China. The price kept falling. In the third batch of national centralized drug procurement, the price of some domestic generic sildenafil was as low as 2.08 yuan per tablet. In addition to male Viagra, people have also invented Addiy, a female Viagra. Similar to the fate of sildenafil, its main ingredient, flibanserin, was originally used as an antidepressant, but the effect was not good. Researchers found that it seemed to increase the user's sexual desire by affecting the receptors of neurotransmitters. It can be used to treat female frigidity. However, its efficacy is not satisfactory, almost the lowest value that can be proven to be effective in the medical field. Therefore, it is not well received. |
