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...

The first dipeptidyl-peptidase-IV (DPP-4) inhibitor for the treatment of type 2 diabetes became available in 2006. Since then, the number of DPP-4 inhibitors has increased and DPP-4 inhibitors have developed into an important drug class. DPP-4 inhibitors act by increasing endogenous GLP-1 and GIP concentrations. Via this mechanism, insulin secretion is glucose-dependently stimulated and glucago...

Type 2 diabetes mellitus (T2DM) has a high prevalence and incidence around the world. The complex pathophysiology mechanism is among the barriers for diabetes treatment. Type 2 diabetes patients have dysfunction in incretin hormones (as glucagon-like peptide-1 or GLP-1, and glucose-dependent insulinotropic polypeptide or GIP). By inhibiting the dipeptidyl peptidase-4 (DPP-4) enzyme, it is possi...

For patients with type 2 diabetes mellitus, management of hyperglycemia is typically complex, and few patients successfully achieve and maintain recommended targets for glycated hemoglobin (HbA1c). Increasingly, combination therapy is recommended early in the disease course, or even directly at diagnosis in patients with relatively high HbA1c levels. A recent randomized, placebo-controlled, Pha...

INTRODUCTION The first-choice drug therapy in the management of type 2 diabetes is metformin . However, most patients require a combined therapy to reach and/or maintain targets of glucose control. Dipeptidyl peptidase-4 (DPP-4) inhibitors, commonly referred to as gliptins, offer new options for combined therapy with metformin. Linagliptin is the most recently launched gliptin, with a unique ph...

The rate of occurring of Type 2 diabetes mellitus have been proportionally increased with respect to time in the last 50 years. Multiple therapies are required by the type 2 diabetes patients r proper treatment of hyperglycaemic condition Linagliptin is the latest approved oral hypoglycaemic agent which act by inhibition of DPP-4 (Dipeptidyl peptidase-4) enzyme. On 2 May 2011, USFDA approved Li...

BACKGROUND Addition of a sulphonylurea to metformin improves glycaemic control in type 2 diabetes, but is associated with hypoglycaemia and weight gain. We aimed to compare a dipeptidyl peptidase-4 inhibitor (linagliptin) against a commonly used sulphonylurea (glimepiride). METHODS In this 2-year, parallel-group, non-inferiority double-blind trial, outpatients with type 2 diabetes and glycate...

BACKGROUND Type 2 diabetes mellitus is associated with cognitive dysfunction and an increased risk of dementia. Linagliptin is a glucose-lowering agent of the dipeptidyl peptidase-IV (DPP-IV) inhibitor class that is of particular interest for the prevention of accelerated cognitive decline, because it may potentially benefit the brain through pleiotropic effects, beyond glucose lowering. This p...

BACKGROUND This study aimed to evaluate the efficacy and safety of linagliptin (a novel dipeptidyl peptidase (DPP)-4 inhibitor) on glucose metabolism and β-cell function in Chinese patients with newly-diagnosed, drug-naïve type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS Newly-diagnosed and drug-naïve T2DM patients were enrolled. After 4-week lifestyle modulation and 2-week placebo run-in,...

BACKGROUND Advanced glycation end products (AGEs) and receptor RAGE interaction play a role in diabetic vascular complications. Inhibition of dipeptidyl peptidase-4 (DPP-4) is a potential therapeutic target for type 2 diabetes. However, the role of DPP-4 in AGE-induced endothelial cell (EC) damage remains unclear. METHODS In this study, we investigated the effects of DPP-4 on reactive oxygen ...
