社会心理因素在勃起功能障碍(ED)的发病过程中占到了十分重要的地位。一种理想的治疗药物应能给患者及其伴侣带来满意的社会心理收益。“心理与人际关系量表”(PAIRS量表)既能评价ED对患者及其伴侣的心理及人际关系影响,又能预测ED患者对治疗的满意度。利用PAIRS量表对5型磷酸二酯酶(phosphodies-terasetype5,PDE5)抑制剂治疗ED的疗效进行评估,发现在降低ED患者性活动相关性时间顾虑方面,他达拉非明显优于西地那非和伐地那非。这也正是ED患者及其伴侣在临床治疗条件下偏好使用他达拉非的深层原因。与此相关的药物属性则是他达拉非长达36h的卓越疗效。
Social psychological factors play an important role in the pathogenesis of erectile dysfunction (ED). An ideal medicine should give patients and their partners a satisfying psychosocial benefit. The Psychological and Interpersonal Relationship Scale (PAIRS) can assess the impact of ED on both the psychological and interpersonal relationships of patients and their partners and the satisfaction of ED patients with treatment. The efficacy of phosphodiesterase type 5 (PDE5) inhibitors in the treatment of ED was evaluated using the PAIRS scale and found that tadalafil was significantly superior to sildenafil in reducing the time-related concerns of sexual activity in ED patients Non-and vardenafil. This is exactly why ED patients and their partners prefer to use tadalafil under clinical conditions. The drug attribute associated with this is the excellent efficacy of tadalafil for up to 36 hours.
