The purpose of this study is usually to make rosuvastatin calcium (ROS) and atenolol (AT) bilayer tablets to treat coexisting dyslipidemia and hypertension with a single item. ROS was chosen for the immediate-release layer from the constructed tablets, whereas AT was selected for the sustained-release layer. The solid dispersion of ROS with sorbitol (1:3 w/w) was utilized inside the immediate-release layer even though hydroxypropyl methylcellulose (HPMC), ethylcellulose (EC), and sodium bicarbonate had been incorporated in to the floating sustained-release layer. The concentrations of HPMC and EC had been optimized by employing 32 full factorial styles to sustain AT release. The bilayer tablets have been prepared by the direct compression technique. The immediate-release layer revealed that 92.34 two.27 of ROS was released within 60 min at a pH of 1.two. The second sustained-release layer with the bilayer tablets exhibited delayed release of AT (96.65 3.36 within 12 h) under the identical situations. The release of ROS and AT from the ready tablets was located to obey the non-Fickian diffusion and mixed models (zero-order, Higuchi and Korsmeyer eppas), respectively. Preclinical studies utilizing rabbit models investigated the impact of ROS/AT tablets on lipid profiles and blood stress. A high-fat diet program was used to induce obesity in rabbits. Bilayer ROS/AT tablets had a outstanding impact on decreasing the lipid profiles, slowing weight achieve, and lowering blood stress to normal levels when in comparison with the manage group.

In current years, the use of bilayer or multilayer tablets to combine two or much more drugs into a single dosage type has elevated [4]. Such tablets give different drug release patterns (quick with sustained drug release). In addition they.
