BioSci. 2(2014) 44-49 Abstract This study was to compare the bioavailability and pharmacokinetic properties of test product of Metformin hydrochloride extended release formulation of 1000 mg tablet with reference product of Metformin Hydrochloride (Glucophage®) extended release formulation of 1000 mg in Indian healthy male vo...

Bilayer tablets of Metformin hydrochloride and Glipizide were formulated. Glipizide is a poor water soluble (BCS class 2) antidiabetic drug. The present study aims to increase the solubility of Glipizide by solid dispersion technique using sodium starch glycolate and crospovidone as super disintegrants. Metformin hydrochloride was formulated by using Hydroxy Propyl Methyl Cellulose as the matri...

In this work, a combined discrete and continuous wavelet transform analysis was developed for simultaneous spectrophotometric determinations of metformin hydrochloride and glibenclamide, two antidiabetic drugs, in binary mixtures without any chemical pretreatment. Absorption spectra were subjected to the 4-level db4 discrete wavelet transform (DWT) for signal de-noising. Selected continuous wav...

A simple, precise, rapid, selective, and economic high-performance thin layer chromatographic method has been established for simultaneous estimation of Metformin Hydrochloride and Linagliptin in formulation. The chromatographic separation was performed on precoated silica gel 60 GF254 plates with acetone-methanoltoluene-formic acid 4:3:2:1 (v/v/v/v) as mobile phase. The plates were developed t...

Metformin hydrochloride exhibits poor compressibility during compaction, often resulting in weak and unacceptable tablets with a high tendency to cap. The purpose of this study was to develop directly compressible metformin hydrochloride by the spray-drying technique in the presence of polymer. Metformin hydrochloride was dissolved in solutions containing a polymer, namely polyvinylpyrrolidone ...

Objective: To analyse the curative effect of traditional Chinese medicine combined with metformin hydrochloride on diabetes and its effect on TNF-α, MCP-1 and NO. Methods: 80 cases of diabetics who were treated at XX hospital from January of 2014 to January of 2015 were chosen as research subjects, according to random indicator method divided into control group and experimental group with 40 ca...

We describe an analysis for metformin in plasma and urine by use of cation-exchange "high-performance" liquid chromatography. The assay requires only 0.5 mL of sample and involves pretreatment with trichloroacetic acid containing an internal standard (1-propylbiguanide), followed by centrifugation and injection into the chromatograph. The column eluent is monitored at 230 nm. Metformin and 1-pr...

A high performance reverse phase liquid chromatographic procedure is developed for simultaneous estimation of metformin hydrochloride and pioglitazone hydrochloride in combined tablet dosage form. The mobile phase used was a combination of acetonitrile:water:acetic acid (60:40:0.3) and the pH was adjusted to 5.5 by adding triethylamine. The detection of the combined dosage form was carried out ...

CLINICAL PHARMACOLOGY Mechanism of Action Metformin is an antihyperglycemic agent which improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Its pharmacologic mechanisms of action are different from other classes of oral antihyperglycemic agents. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucos...

BACKGROUND The purpose of the study was to investigate effects of ethyl eicosapentaenoic acid on pharmacokinetics of metformin. Pharmacokinetic profiles of metformin and ethyl eicosapentaenoic acid when delivered separately or together in solid dose form were investigated and compared to determine whether the solid dose resulted in an altered metforminpharmacokinetics when given with or without...
