Erectile dysfunction (ED) is a very common disorder with a deep impact on patients and their partners. Several options are now available for treating ED; oral pharmacotherapy with phosphodiesterase-5 (PDE5) inhibitors currently represents the first-line option for many ED patients. Vitaros©/Virirec© is new topical, non-invasive treatment for ED that offers the combination of an active drug (alprostadil, a synthetic PGE1) with a skin enhancer that improves its local absorption directly at the site of action. Vitaros©/Virirec© has a favorable pharmacodynamic profile and is poorly absorbed in systemic circulation. This makes it suitable in any circumstances and results in a reduced risk of adverse events (AEs), being systemic AEs reported in only 3% of the treated population. Its clinical efficacy has been demonstrated in both phase II and III trials, showing a global efficacy up to 83% with the 300 μg dose in patients with severe ED significantly better than placebo. Its fast onset of action together with its favorable toxicity profile and lack of interactions with other drugs makes Vitaros©/Virirec© a first-line therapeutic option for patients with ED, particularly for individuals who are reluctant to take systemic treatments or with AEs. It may also have an important role in patients not responding to PDE5 inhibitors, particularly those with ED after radical prostatectomy.
勃起功能障碍(ED)是一种非常常见的疾病,对患者及其伴侣有深远影响。目前有多种治疗ED的方法;使用磷酸二酯酶-5(PDE5)抑制剂的口服药物治疗目前是许多ED患者的一线选择。Vitaros©/Virirec©是一种新型的局部非侵入性ED治疗药物,它将活性药物(前列地尔,一种合成的前列腺素E1)与一种皮肤增强剂相结合,可在作用部位直接改善其局部吸收。Vitaros©/Virirec©具有良好的药效学特征,在体循环中吸收较差。这使其适用于任何情况,并降低了不良事件(AE)的风险,仅3%的治疗人群报告有全身性AE。其临床疗效已在II期和III期试验中得到证实,在重度ED患者中,300μg剂量的总体疗效高达83%,显著优于安慰剂。其起效迅速,毒性特征良好,且与其他药物无相互作用,这使得Vitaros©/Virirec©成为ED患者的一线治疗选择,特别是对于那些不愿接受全身治疗或有AE的个体。它在对PDE5抑制剂无反应的患者中,尤其是前列腺癌根治术后发生ED的患者中,可能也具有重要作用。
