    • The disclosed invention is drawn to pharmaceutical tablets that provide delivery of active agents having at least three oxygen-containing groups, a tri-oxy active agent, as well as a second active ingredient. Non-limiting examples of three oxygen-containing group active agents include guaifenesin, codeine, hydrocodone, and their pharmaceutically acceptable salts. In one embodiment, a pharmaceutical tablet for oral administration once every 12 hours is provided. The tablet includes a first active agent that is a tri-oxy active agent, a second active agent, and a release rate controlling non-ionic oxyl-containing hydrophilic polymer. The total oxyl content of the hydrophilic polymer in the tablet is from about 4×10−4 moles to about 2.0×10−3 moles. The tablet is a matrix tablet and a single-dose administration of one or more tablets to a subject under fasted conditions provides a mean Cmax for each of the first active agent and the second active agent that is 70% to 135% of a respective mean Cmax provided by administering an immediate release oral dosage form to a subject under fasted conditions every 4 to 6 hours over a 12 hour time period, wherein cumulative dosage amounts administered over the 12 hour time period of each active agent is equivalent to the respective amount of each active agent in the pharmaceutical tablet.
    • 所公开的发明涉及提供具有至少三个含氧基团的活性剂,三氧基活性剂以及第二活性成分的药物片剂。 三种含氧基活性剂的非限制性实例包括愈创甘油醚,可待因,氢可酮及其药学上可接受的盐。 在一个实施方案中,提供了每12小时一次口服给药的药物片剂。 片剂包括第一活性剂,其为三氧基活性剂,第二活性剂和释放速率控制非离子含氧基的亲水性聚合物。 片剂中亲水性聚合物的总氧基含量为约4×10 -4摩尔至约2.0×10 -3摩尔。 片剂是基质片剂,并且在禁食条件下向受试者单剂量施用一种或多种片剂提供了每种第一活性剂和第二活性剂的平均C max,其为相应平均值的70%至135% Cmax通过在禁食状态下每隔4〜6小时在12小时时间内向受试者施用立即释放的口服剂型,其中在每个活性剂的12小时时间段内施用的累积剂量相当于 药物片剂中的每种活性剂。
