摘要： A stable pharmaceutical composition consisting of (a) benazepril, in free or pharmaceutically acceptable salt form; and (b) amlodipine, in free or pharmaceutically acceptable salt form. The composition is free of alkali and alkaline earth metal carbonates and phosphates. The composition is also free of excipients which increase the pH of microenvironment above 5. It is therefore not required to physically separate the two drugs from each other.
摘要翻译：由（a）贝那普利，游离或药学上可接受的盐形式组成的稳定的药物组合物; 和（b）氨氯地平，游离或药学上可接受的盐形式。该组合物不含碱金属和碱土金属的碳酸盐和磷酸盐。该组合物也不含增加微环境高于5的pH值的赋形剂。因此不需要将这两种药物彼此物理分离。

摘要： A pharmaceutical composition for controlled drug delivery comprising a β-lactam antibiotic or its pharmaceutically acceptable hydrates, salts or esters, and one or more carbomers. The above β-lactam antibiotics formulation avoids the limitations of known β-lactam controlled release form which are found to be either complex and/or cost-extensive to obtain requiring multiphase and/or selective coatings or fail to achieve the desired controlled release for once daily dosage form. Importantly, in the β-lactam antibiotic form of the above the rate-controlling polymer wherein the Cmax of the formulation is substantially the same as that of a single dose of the immediate release formulation. Also advantageously the formulation achieves a rate controlling polymer wherein the T>MIC for the formulation is more than 17 hours when the MIC is 0.25 mcg/ml and more than 10 hours when the MIC is 2 mcg/ml. The above β-lactam antibiotic form is thus directed to serve as the much desired simple and cost-effective controlled release form suitable for once daily administration.
摘要翻译：用于受控药物递送的药物组合物，其包含β-内酰胺抗生素或其药学上可接受的水合物，盐或酯，以及一种或多种卡波姆。上述β-内酰胺抗生素制剂避免了已知的β-内酰胺控制释放形式的限制，其被认为是复杂的和/或成本广泛的以获得需要多相和/或选择性涂层或不能达到期望的一次控制释放日剂量。重要的是，在上述β-内酰胺抗生素形式中，速率控制聚合物，其中制剂的最大值与单剂量的立即释放制剂基本上相同。还有利地，制剂实现速率控制聚合物，其中当MIC为0.25mcg / ml时，制剂的T> MIC大于17小时，当MIC为2mcg / ml时超过10小时。因此，上述β-内酰胺抗生素形式被用作适合于每日一次给药的理想的简单和成本有效的控制释放形式。

摘要： Stabilized pharmaceutical solid composition of ACE inhibitor comprising an ACE inhibitor and a selective dosage formulation thereof comprising of meglumine. The ACE inhibitor selectively combined with a dosage form including essentially the meglumine is surprisingly found to avoid the degradation of ACE inhibitor by such dosage forms especially the commonly used pharmaceutical excepients. In particular, the presence of the meglumine in the dosage form for the active along with the active ACE inhibitor surprisingly avoid the degradation of the ACE inhibitor due to a) cyclization via internal nucleophilic attack to form substituted diketopiperazines, b) hydrolysis of the side chain ester group, and c) oxidation to form products having often unwanted coloration.
摘要翻译：稳定的ACE抑制剂的药物固体组合物，其包含ACE抑制剂及其选择性剂量制剂，其包含葡甲胺。令人惊奇地发现，选择性地与包含基本上葡甲胺的剂型组合的ACE抑制剂避免了ACE抑制剂通过这样的剂型，特别是常用的药物的降解。特别地，活性剂剂型中的葡甲胺与活性ACE抑制剂的存在令人惊奇地避免了由于通过内部亲核攻击而环化形成取代的二酮哌嗪的ACE抑制剂的降解，b）侧链的水解酯基，和c）氧化形成通常不需要着色的产品。

摘要： A pharmaceutical composition in the form of a tablet for controlled release of an active ingredient comprises cefaclor, cephalexin, or their pharmaceutically acceptable hydrates, salts, or esters as active ingredient, and a mixture of hydrophilic polymers of different viscosity grades selected from the group consisting of at least one hydroxypropyl methylcellulose and at least one hydroxypropylcellulose. The composition optionally also contains one or more of a water soluble or water dispersible diluent. The quantities of the hydrophilic polymers and water soluble or water dispersible diluent are such that the therapeutically effective active ingredient is released at a rate suitable for twice daily administration of the pharmaceutical composition to human subjects. The tablets may also be coated with a rapidly dissolving water soluble polymeric film coat. In a preferred embodiment, the composition comprises about 50% to about 90% by weight of cefaclor, cephalexin, or their pharmaceutically acceptable hydrates, salts, or esters, and about 5% to about 35% of a mixture of hydrophilic polymers of different grades, wherein the hydrophilic polymers comprise about 0.1% to about 20% by weight of hydroxypropyl methylcellulose and about 0.1% to about 20% by weight of hydroxypropyl cellulose.
