Description

一种用于治疗早泄和勃起功能障碍的复方制剂
技术领域
本发明涉及泌尿科学技术领域,特别是涉及一种用于治疗早泄和勃起功能障碍的复方制剂。
背景技术
早泄是最常见的射精功能障碍,以性交之始即行排精,甚至性交前即泄精,不能进行正常性生活为主要表现,发病率占成年男子的1/3以上。早泄的定义尚有争议,通常以男性的射精潜伏期或女性在性交中达到性高潮的频度来评价,如以男性在性交时失去控制射精的能力,则阴茎插入阴道之前或刚插入即射精为标准;或以女性在性交中达到性高潮的频度少于50%为标准来定义早泄,但这些都未被普遍接受。因为男性的射精潜伏期受年龄、禁欲时间长短、身体状况、情绪心理等因素影响,女性性高潮的发生频度亦受身体状态、情感变化、周围环境等因素影响。另外,射精潜伏期时间的长短也有个体差异,一般认为,健康男性在阴茎插入阴道2-6分钟后发生射精,即为正常。
勃起功能障碍是最常见的一种男性勃起功能障碍,指阴茎持续不能达到或维持足够的勃起以完成满意满意性生活,病程3个月以上。既往将男子“性无能”泛称为“阳萎”,其科学界定不确切,并且带有歧视性贬义。直到1992年,美国国立卫生院经有关专家讨论,决定用勃起功能障碍(ED)一词代替阳萎,并将阴茎勃起功能障碍定义为:阴茎持续不能达到和(或)维持足够的勃起以获得满意的性生活。
目前治疗勃起功能障碍(ED)与早泄(PE)国内的药物有中成药,包括金匮肾气丸、六味地黄丸等,疗效有待商确。治疗勃起功能障碍的西药有枸橼酸西地那非、酚妥拉明、他达拉非等,治疗早泄的药除中药外仅有盐酸达帕西汀(进口)。目前针对勃起功能障碍和早泄的双效治疗国内没有,国外的复方制剂有阿伐那非+达帕西汀、枸橼酸西地那非+达帕西汀、他达拉非+达帕西汀。
由于ED患者多数伴有紧张、压力、抑郁、焦虑和夫妻感情不和等精神心理因素,有时被临床医生忽视,或者患者拒绝同时服用抗抑郁药,使得治疗勃起功能的药疗效受到影响。
发明内容
本发明的目的就在于为了解决上述问题而提供一种用于治疗早泄和勃起功能障碍的复方制剂。
本发明通过以下技术方案来实现上述目的:
一种用于治疗早泄和勃起功能障碍的复方制剂,由以下重量的药物组成:枸橼酸西地那非40-120mg,盐酸帕罗西汀10-50mg。
进一步的,由以下重量的药物组成:枸橼酸西地那非50mg,盐酸帕罗西汀20mg。
本发明的有益效果在于:枸橼酸西地那非治疗勃起功能障碍,盐酸帕罗西汀解除患者焦虑抑郁的情绪,从而提高对勃起功能障碍的治疗效果;盐酸帕罗西汀治疗早泄,枸橼酸西地那非治疗因盐酸帕罗西汀产生的勃起功能障碍的副作用,从而提高了早泄治疗的有效率。
具体实施方式
下面将结合实施例对本发明的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
一种用于治疗早泄和勃起功能障碍的复方制剂,由以下重量的药物组成:枸橼酸西地那非50mg,盐酸帕罗西汀20mg。
治疗勃起功能障碍时,枸橼酸西地那非为主要作用,枸橼酸西地那非是高度选择性磷酸二酯酶5(PDE5)抑制剂,PDE5在阴茎海绵体中高度表达,而在其它组织中(包括血小板、血管和内脏平滑肌、骨骼肌),表达低下,西地那非通过选择性抑制PDE5,增强一氧化氮(NO)-cGMP途径,升高cGMP水平而导致阴茎海绵体平滑肌松弛,使勃起功能障碍患者对性刺激产生自然的勃起反应,此时盐酸帕罗西汀解除患者焦虑抑郁的情绪,从而与西地那非产生协同作用。
治疗早泄时,所述盐酸帕罗西汀为主要作用,盐酸帕罗西汀是一种选择性5-羟色胺再摄取抑制剂(SSRI),口服后能选择抑制5-HT转运体,促使受体去敏感化,阻断突触前膜再摄取5-HT,提高突触间隙内5-HT浓度,延长5-HT作用时间,发挥着显著的抗焦虑、抗抑郁作用,而盐酸帕罗西汀起到延长射精时间的同时,会引起患者勃起功能障碍,此时枸橼酸西地那非用于治疗该副作用,进而产生协同作用。
使用方法:性生活前1.5—2小时服用;体重较重的人,适当增加半片到1片,最多每天一次。
禁忌:禁止与胆胺氧化酶抑制剂合用;服用任何剂型硝酸酯的患者,无论是规律服用或间断服用,均不可服用。
以上显示和描述了本发明的基本原理、主要特征和优点。本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明范围内。
