Abstract

يتم الحصول على عقار ذو إطلاق متأخر الى القولون من تركيبة ذات إطلاق متأخر تشتمل على جزء رئيسي وطبقة تغليف لهذا الجزء الرئيسي. يشتمل الجزء الرئيسي على عقار وتشتمل طبقة التغليف على طبقة خارجية وطبقة واحدة على الأقل ما بين الجزء الرئيسي والطبقة الخارجية التي يتم اختيارها من المجموعة التي تتكون من طبقة عازلة وطبقة داخلية. حيث تشتمل الطبقة الخارجية المذكورة على مزيج من مواد أولى بوليميرية والتي هي عرضة لهجوم البكتيريا الموجودة في القولون ويكون للمواد البوليميرية الثانية ذات درجة حموضة بدرجة تصل إلى حوالي 5 أو أعلى من ذلك، تشتمل الطبقة الداخلية على مواد بوليميرية ثالثة والتي هي قابل للذوبان في السوائل المعوية او سوائل الجهاز الهضمي ويجري إختبار المواد البوليميرية الثالثة من حمض بولي كربوكسيلية محيدة بشكل جزئي على الأقل وبوليمر غير أيونية. وفي التجسيدات التي تكون في المواد البوليميرية الثالثة هي بوليمرات غير أيونية، تشتمل الطبقة الداخلية على أحد العوامل المنظمة على الأقل وقاعدة. تشتمل الطبقة العازلة على بوليمر غير ايوني الذي يكون قابل للذوبان في السوائل المعوية او سوائل الجهاز الهضمي. حيث تطبق الطبقة الخارجية مباشرة على الطبقة الداخلية او الطبقة العازلة باستخدم مستحضر غطاء التغليف الذي يتم تشكله من مزج المواد البوليميرة الأولى في وسط مائي مع مادة بوليمرية ثانية في وسط عضوي. ووتضمن مزايا التركيبات وفقا للاختراع الحالي على مواد تسريع تحلل العقار عندما يتعرض لظروف القولون مما يخفض أو يزيل تأثير الطعام و/أو الكحول على تحرر العقار بعد تناوله.
