The invention discloses a preparation process of a quetiapine fumarate slow release tablet, belonging to the technical field of preparing medicinal slow/controlled-release preparations. In the process, a soluble slow-release accessory is used as a retarding agent, and slow-release particles are prepared by using a fusion-method solid dispersion technology and are tabletted. The quetiapine fumarate slow release tablet is the slow-release matrix tablet prepared by using a process of externally covering the tablet with a quick-release thin-film coating. The quetiapine fumarate in the invention has the in-vitro release characteristics as follows: after 750ml of 0.1NHCl is added for 2 hours, the release amount of quetiapine fumarate within 0-2 hours is 0-35%, and after 250ml of K3PO4 is added, the release amounts of the quetiapine fumarate within 2-8 hours, 8-12 hours and 12-20 hours are respectively 35-60%, 60-80% and 80-100%. The process has the advantages of simple and safe flow, controllable ...

The invention discloses a preparation process of compound pioglitazone and metformin sustained-release tablets, belonging to the technical field of preparation of pharmaceutical sustained and controlled release formulations. The preparation process adopts metformin sustained-release matrix tablets with microporous film coatings, pioglitazone quick-release film coatings are externally coated, therefore, the quick-release film coatings quickly release the pioglitazone, and the sustained-release matrix tablets with microporous film coatings dually retard and control the metformin to slowly release for as long as 24 hours. The in vitro release characteristics of pioglitazone in the compound pioglitazone and metformin sustained-release tablets is: 50-70% in 5-10 minutes, 60-100% in 10-30 minutes, and 80-100% in 30-45 minutes; and the in vitro release characteristics of metformin is 0-30% in 1-3 hours, 30-60% in 2-8 hours, 60-80% in 8-12 hours and 80-100% in 12-20 hours. The process has a simple ...
