20110223247 | PHARMACEUTICAL COMPOSITIONS FOR RELEASE CONTROL OF METHYLPHENIDATE - Disclosed is a pharmaceutical composition for release control comprising a plurality of particles for release control. The plurality of particles for release control comprise a core material containing methylphenidate and a polymer coating layer for release control formed on the core material. The plurality of particles for release control are divided into two or more groups based on the average thickness of the polymer coating layer for release control. The particle groups are identical in terms of the composition of the polymer in the polymer coating layer, but are different in terms of the average thickness of the coated layer. The pharmaceutical composition for release control according to the present invention may control the release pattern of methylphenidate contained in the core material as desired, and can be used as an oral formulation in a variety of forms such as orally disintegrating tablets, etc. | 09-15-2011 |
20140364513 | HIGHLY ROBUST FAST-DISINTEGRATING TABLET AND PROCESS FOR MANUFACTURING THE SAME - Disclosed are an oral formulation which disintegrates quickly in the oral cavity; a fast-disintegrating tablet having fast disintegrability and high hardness, and a process for manufacturing the same. In addition, slightly wetted granules for manufacturing said fast-disintegrating tablet and a process for manufacturing the same are disclosed. | 12-11-2014 |
20150086623 | CONTROLLED-RELEASE PHARMACEUTICAL COMPOSITION INCLUDING TAMSULOSIN OR PHARMACEUTICALLY ACCEPTABLE SALTS THEREOF, AND ORAL FORMULATION INCLUDING THE SAME - A controlled-release pharmaceutical composition including first and second groups of microparticles, each of the microparticles including a core including tamsulosin or pharmaceutically acceptable salts thereof, a controlled-release polymer coating layer formed on the core, and an enteric polymer outer layer formed on the controlled-release polymer coating layer, wherein the average thickness of the controlled-release polymer coating layer is different in each of the first and second groups of microparticles, and an oral formulation including the same, are provided. This pharmaceutical composition can easily control the extent of release of an active ingredient depending on changes in pH in the intestinal tract and the release pattern of the active ingredient in the small intestine, thus preventing the active ingredient from being rapidly transferred into the blood to thereby minimize side-effects, and maintaining the effective blood concentration of the active ingredient for a predetermined period of time. Furthermore, this composition can shield the bitter taste of the active ingredient even when exposed to the inside of the mouth, thus increasing the therapeutic effects for patients upon oral administration. | 03-26-2015 |
