In the case of T the tmax achieved slowly and the drug availability was found for longer period of time. The AUC0–t of R was found 4922.56 ng min/ml whereas an increase in AUC0–t (25013.5 ng min/ml) was observed in the T which indicated the LAMI bioavailability. A decrease in the elimination rate (Kel) from 0.5278 to 0.0719 h−1 for R and T respectively,
indicated the slow release rate of the drug in the body. The elimination half life (t½) of the R was 1.66 h and that of the T was 9.67 h which showed the prolonged availability of LAMI. A significant difference in tmax and Cmax was INCB024360 price observed between individual subjects of R and T which could be due to inter-subject variability. The overall Cmax, Tmax, AUC0–t, Kel and t1/2 were completely different between both test and reference formulation. Therefore the prepared formulation released the drug for a prolonged period of time. Extended release matrix tablets of lamivudine (200 mg) prepared employing HPMC alone and HPMC-PEO combination as matrix former in different proportions gave slow release of the drug over 14 h. Drug release was diffusion controlled depending on polymer concentration and followed zero order Sotrastaurin kinetics. Significant linearity was observed between polymer concentration and drug release rate and stable during short-term accelerated stability testing. The
in vivo bioavailability and drug release kinetics of formulation F-3 were successfully tested after oral administration in rabbits. Based on the pharmacokinetic parameters obtained, the formulation F-3 could be employed for further bioavailability studies in clinical subjects. Therefore the prepared formulations of LAMI containing HPMC-PEO combination as rate retarding polymers could be used for potential industrial application. All authors have none to declare. The authors greatly acknowledge the Alchem Laboratories, Mumbai, India, for the supply of lamivudine as gift sample. The authors are grateful to Indian Institute of Chemical Technology, Hyderabad, India for their help in performing the characterization studies. “
“Diabetes
mellitus (DM) is a chronic disease caused by inherited or acquired deficiency in insulin secretion and by decreased responsiveness of the organs to secreted insulin.1 Diabetes mellitus is a syndrome, initially characterized by a loss of glucose to homeostasis resulting from defects in insulin secretion, insulin action both resulting impaired metabolism of glucose and other energy yielding fuels such as lipids and proteins.2 DM is a leading cause of end stage kidney disease, cardiomyopathy and heart attacks, strokes, retinal degeneration leading to blindness and non-traumatic amputations.3 Dyslipidemia, quite common in diabetic patients, is the main risk Libraries factor for cardiovascular and cerebrovascular diseases. DM is currently one of the most costly and burdensome chronic disease and is a condition that is increasing in epidemic proportions throughout the world.
