Comparison of alogliptin and glipizide for composite endpoint of glycated haemoglobin reduction, no hypoglycaemia and no weight gain in type 2 diabetes mellitus

This was a post-hoc analysis of a 2-year, double-blind study of 2639 patients with type 2 diabetes mellitus (T2DM) inadequately controlled on metformin monotherapy which assessed achievement of a composite endpoint of sustained HbA1c reduction (≤7.0% at Week 104 or ≥0.5% from baseline) with no weight gain and no hypoglycaemic events with alogliptin 12.5 mg and 25 mg daily or glipizide (≤20 mg daily), each added to metformin With an HbA1c target of ≤7.0%, 24.2% and 26.9% of patients treated with alogliptin 12.5 mg and 25 mg, respectively achieved the composite endpoint vs. 10.7% of patients treated with glipizide (both p<0.001). With a criterion of ≥0.5% decrease in HbA1c, the composite endpoint was reached in 22.5%, 25.2% and 10.4% of patients treated with alogliptin 12.5 mg, alogliptin 25 mg and glipizide, respectively. Odds ratios of achieving the composite endpoint favoured alogliptin in the primary analysis set and in all subgroups of patients. Patients with T2DM failing metformin monotherapy are more likely to achieve sustained glycaemic control with no hypoglycaemia or weight gain at 2 years with alogliptin than with glipizide.

Natural sensitizers-mesoporous TiO2 hybrid nanomaterial for future optoelectronic applications

AbstractOptoelectronics deals with the design and development of electronic devices including photodetector (PD), solar cells and LEDs for light detection, generation and application for a variety of purposes. It includes X-rays, Gamma rays, Infrared, Ultraviolet and Visible light. In the current work, we developed a self-powered and efficient UV–Visible PD by sensitizing mesoporous TiO2 powder with a natural sensitizer Ficus Benghalensis (Banyan) and Rubia Cordifolia (Manjishtha). Prominent enhancement of visible light absorption was noted due to sensitizers as compared to pure TiO2 with the decrease in band gap from 3.13 eV to 3.01 eV. TiO2 photoanodes fabricated with and without dye loading were characterized using XRD, FESEM and UV–Visible and FTIR spectroscopy and used to fabricate a PD device with an active area of 0. 25 cm2. At zero bias, the Banyan-loaded TiO2 PD (B-TiO2) demonstrates enhanced photo response by nearly three times than Manjishtha-loaded PD (M-TiO2). At zero bias voltage, the PD (B-TiO2) displayed very high photosensitivity (8665), Dark current density (126 nA), Photocurrent density (158 µA), Photoresponsivity (1.88 mA/W), Rise time (0.31S) and Decay time (0.35S), respectively. Therefore, the use of novel dye for electricity generation in this study opens new routes to design future optoelectronics devices

A Two-Sequence, Four-Period, Crossover, Full-Replicate Study to Demonstrate Bioequivalence of Carbamazepine Extended-Release Tablets in Healthy Subjects under Fasting and Fed Conditions

Carbamazepine is a first-line antiepileptic drug (AED) used for the treatment of partial and tonic-clonic seizures. We conducted an open label, balanced, randomized, two-treatment, two-sequence, four-period, single oral dose, full-replicate crossover study to assess and compare the&nbsp; bioequivalence of&nbsp; test&nbsp; product&nbsp; Carbamazepine extended release tablets USP 400 mg with reference&nbsp; product Tegretol®-XR 400 mg (Carbamazepine extended release tablets), respectively in&nbsp; healthy subjects under fasting and fed conditions. Blood samples were collected pre-dose and at regular intervals post-dose up to 240.00 hours. The plasma concentration was analyzed by a validated LC-MS/MS method and the reference-scaled and the unscaled procedure was used to determine bioequivalence for the pharmacokinetics parameters, Cmax, AUC0–t, AUC0-inf, Tmax, T½, Kel and AUC extrapolated was calculated. The results showed that the geometric mean ratios of Cmax, AUC0–t and AUC0-inf were 113.04%, 108.33% and 108.15% respectively, in the fasting conditions and 113.99%, 110.13% and 111.41%, respectively, in the fed conditions and the 90% confidence intervals were all within the range of 80.00% to 125.00%. It can be concluded from the result that the test product Carbamazepine extended release tablets based on osmotic release system (OROS) are bioequivalent to the reference product Tegretol®-XR tablets.
