伟哥 （药物名： Sildenafil）
西地那非（英语：Sildenafil），又译昔多芬，是一种研发治疗心血管疾病药物时意外发明出的治疗男性勃起功能障碍药物，一般以其商业用名Viagra（中国大陆注册名万艾可，台湾和港澳商品名威而钢）广为人知，但在中国大陆其中文俗名“伟哥”更深入民心。目前辉瑞制药对西地那非的专利权已过期，其他厂商可以合法制造同种药物
Cialis （药物名： Tadalafil）
勃起功能障碍类药物adalafil (INN)[2] is a PDE5 inhibitor marketed in pill form for treating erectile dysfunction (ED) under the name Cialis /siˈælɪs/ see-AL-iss, and under the name Adcirca /ædˈsɜːrkə/ ad-SUR-kə for the treatment of pulmonary arterial hypertension. In October 2011 the U.S. Food and Drug Administration (FDA) approved Cialis for treating the signs and symptoms of benign prostatic hyperplasia (BPH) as well as a combination of BPH and erectile dysfunction when the conditions coincide. It initially was developed by the biotechnology company ICOS, and then again developed and marketed worldwide by Lilly ICOS, LLC, the joint venture of ICOS Corporation and Eli Lilly and Company. Cialis tablets, in 2.5 mg, 5 mg, 10 mg, and 20 mg doses, are yellow, film-coated, and almond-shaped. The approved dose for pulmonary arterial hypertension is 40 mg (two 20 mg tablets) once daily.
Tadalafil is also manufactured and sold under the name of Tadacip by the Indian pharmaceutical company Cipla in doses of 10 mg and 20 mg.
On November 21, 2003 the FDA approved tadalafil (as Cialis) for sale in the United States as the third ED prescription drug pill (after sildenafil citrate (Viagra) and vardenafil (Levitra)). Like sildenafil and vardenafil, tadalafil is recommended as an 'as needed' medication. Cialis is also offered as a once-daily medication.
Tadalafil was approved in May 2009 in the United States for the treatment of pulmonary arterial hypertension[3] and is under regulatory review in other regions for this condition. In late November 2008, Eli Lilly sold the exclusive rights to commercialize tadalafil for pulmonary arterial hypertension in the United States to United Therapeutics for an upfront payment of $150 million.
Avanafil is a PDE5 inhibitor approved for erectile dysfunction by the FDA on April 27, 2012 [1] and by EMA on June 21, 2013.[2] Avanafil is known by the trademark names Stendra and Spedra and was developed by Vivus Inc. In July 2013 Vivus announced partnership with Menarini Group, which will commercialise and promote Spedra in over 40 European countries plus Australia and New Zealand.
[3]Avanafil acts by inhibiting a specific phosphodiesterase type 5 enzyme which is found in various body tissues, but primarily in the corpus cavernosum penis, as well as the retina.[4] Other similar drugs are sildenafil, tadalafil and vardenafil. The advantage of avanafil is that it has very fast onset of action compared with other PDE5 inhibitors. It is absorbed quickly,
reaching a maximum concentration in about 30–45 minutes.[5] About two-thirds of the participants were able to engage in sexual activity within 15 minutes.[5]
Levitra（药物名： Vardenafil）

Priligy and Westoxetin（药物名： Dapoxetine）
达泊西汀（INN, 商品名Priligy），一种新型快速的SSRI，半衰期短，属于选择性5-羟色胺再吸收抑制剂(SSRI，Selective Serotonin Reuptake Inhibitors)，是一款用于治疗16至84周岁男性早泄的药物。达泊西汀最早由美国礼来公司开发，后在2003年被售予美国强生公司，并于2004年作为治疗早发性射精的药物被提交给美国食品药品监督管理局进行批准。在美国，从2003年起达泊西汀就一直处于III期临床试验阶段，但一般认为它将会很快上市。2012年，意大利美纳里尼公司获取了达泊西汀的商业权利，包括在欧洲、大部分的亚洲、非洲、拉丁美洲以及中东进行销售的权利。目前仍未获得美国食品药物管理局批准，但已通过了中国、芬兰、瑞典、葡萄牙、奥地利、意大利、西班牙等国的审批
