    • Compositions and methods of manufacture for producing a medicament composition capable of absorption through the mucosal tissues of the mouth, pharynx, and esophagus. The present invention relates to such compositions and methods which are useful in administering lipophilic and nonlipophilic drugs in a dose-to-effect manner such that sufficient drug is administered to produce precisely a desired effect. The invention also relates to manufacturing techniques that enable therapeutic agents (30) to be incorporated into nondissolvable drug containment matrixes (34) which are capable of releasing the drug within a patient's mouth. An appliance or holder (36) is preferably attached to the drug containment matrix (34). Employing the present invention the drug (30) may be introduced into the patient's bloodstream almost as fast as through injection, and much faster than using the oral administration route, while avoiding the negative aspects of both of these methods. The nondissolvable drug containment matrix (34) may include permeation enhancers to increase the drug absorption by the mucosal tissues of the mouth. The matrix composition (34) may also include pH buffering agents to modify the salival pH thereby increasing the absorption of the drug (30) through the mucosal tissues.
    • 用于生产能够通过口,咽和食道的粘膜组织吸收的药物组合物的组合物和制造方法。 本发明涉及这样的组合物和方法,其可用于以剂量 - 效应方式施用亲脂性和非嗜好性药物,使得施用足够的药物以精确地产生所需效果。 本发明还涉及使治疗剂(30)能够并入不可溶解的药物容纳基质(34)中的制造技术,其能够在患者口腔内释放药物。 器具或保持器(36)优选地附接到药物容纳基质(34)。 使用本发明,药物(30)可以几乎与通过注射一样快地引入患者的血液中,并且比使用口服给药途径快得多,同时避免了这两种方法的不利方面。 不可溶解的药物抑制基质(34)可以包括渗透促进剂以增加口腔粘膜组织的药物吸收。 基质组合物(34)还可以包括pH缓冲剂,以改变游离pH,从而增加药物(30)通过粘膜组织的吸收。
