insulin-dependent diabetes or adult-onset diabetes) commonly begins as insulin resistance, with cells using insulin incorrectly. Gradually, the pancreas loses its ability to produce insulin. According to the National Institutes of Health, 18.2 million Americans (6.3% of the US population) have diabetes. Type 2 diabetes accounts for ~90% to 95% of all diabetes. This disease is associated with obesity, a family history of diabetes, older age, and physical inactivity. Type 2 diabetes also is more prevalent among African Americans, Hispanic/Latino Americans, American Indians, and some Pacific Islander and Asian Americans. Type 2 diabetes has been treated with several antihyperglycemic drugs. The marketed compound tablet of metformin hydrochloride (MH) and repaglinide (RG) exhibits perfect multidrug therapeutic effect of type 2 diabetes. However, due to the short half life of the drugs, the tablet has to be administered 2 to 3 times a day, causing inconvenience to patient and fluctuations of plasma concentration. Here, a sandwiched osmotic pump tablet was developed to deliver the two drugs simultaneously at zero-order rate, in which MH and RG were loaded in different layers separated by a push layer. The osmotic pump tablet was prepared by a combination of three tableting procedure and film coating method. The factors including type and amount of propellant, osmotic active agents, amount of porogenic agent, coating weight, orifice diameter were optimized. The pharmacokinetic study was performed in beagle dogs, and the drug concentration in plasma samples was assayed by HPLC-MS/MS method. Simultaneous, controlled release of MH and RG in the first 12 and 8 h was achieved from the optimized formulation. Where can i buy prednisolone 5mg Metoprolol asthma Mar 2, 2016.
