    • PROBLEM TO BE SOLVED: To provide a device and method for delivery of an active pharmaceutical ingredient (API) to an anal sphincter.SOLUTION: A rectally insertable device 20 comprises a shell 22 for containing an active pharmaceutical ingredient (API) 24. The upper end and sides of the shell are preferably smoothly continuous, and are formed from a material which is impermeable to the API, such that the API is unable to pass through the shell into the rectum. The shell may be constructed from at least one layer of any non-irritating material which is impermeable to the API and which is sufficiently strong not to tear during insertion into the rectum. The layer should be thin enough so that the shell is sufficiently flexible to avoid unnecessary patient discomfort. The shell should also be compatible with a lubricant used in conjunction with the device. Examples of materials suitable for use in constructing the shell include rubber, latex, silicon, polyvinylchloride, and polyurethane. Preferably, the shell is provided with a rounded tip 27 to minimize discomfort to the subject during insertion.
    • 要解决的问题:提供用于将活性药物成分(API)递送至肛门括约肌的装置和方法。解决方案:直肠可插入装置20包括用于容纳活性药物成分(API)的壳体22。 壳体的端部和侧部优选是平滑连续的,并且由API不透气的材料形成,使得API不能通过壳体进入直肠。 壳可以由至少一层任何不刺激性材料构成,其对于API是不可渗透的,并且在插入直肠期间足够坚固,不会撕裂。 该层应足够薄,使得壳体具有足够的柔韧性,以避免不必要的患者不适。 外壳也应与与设备结合使用的润滑剂相容。 适用于构造壳体的材料的实例包括橡胶,胶乳,硅,聚氯乙烯和聚氨酯。 优选地,外壳设置有圆形尖端27,以最小化插入期间对象的不适。
