Two new classes of oral antidiabetic agents play an increasing role in the management of type 2 diabetes, dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) and sodiumglucose cotransporters type 2 (SGLT2) inhibitors (gliflozins). After failure of a monotherapy with metformin (first pharmacological choice in type 2 diabetes), both may offer an alternative to the add-on of a sulphonylurea, especially in patients at risk of hypoglycaemia. However, the choice between a DPP-4 inhibitor and a SGLT2 inhibitor is not easy and should be oriented based upon the individual patient characteristics...

Many zinc (Zn) complexes have been developed as promising oral antidiabetic agents. In vitro assays using adipocytes have demonstrated that the coordination structures of Zn complexes affect the uptake of Zn into cells and have insulinomimetic activities, for which moderate stability of Zn complexes is vital. The complexation of Zn plays a major role improving its bioavailability. However, investigation of the speciation changes of Zn complexes after oral administration is lacking. A dual radiolabeling approach was applied in order to investigate the speciation of bis(5-chloro-7-iodo-8-quinolinolato)zinc complex [Zn(Cq)2], which exhibits the antidiabetic activity in diabetic mice...

Metformin is a widely used drug for the treatment of type 2 diabetes (T2D). Its blood glucose-lowering effects are initially due to inhibition of hepatic glucose production and increased peripheral glucose utilization. Metformin has also been shown to have several beneficial effects on cardiovascular risk factors and it is the only oral antihyperglycaemic agent thus far associated with decreased macrovascular complications in patients with diabetes. Adenosine Monophosphate Activated-Protein Kinase (AMPK) is a major cellular regulator of lipid and glucose metabolism...

Liver fibrosis is a common pathological condition that occurs in most conditions associated with chronic liver injury. Silymarin is a herbal product widely used for its hepatoprotective effect. Sitagliptin, a dipeptidyl peptidase-4 inhibitor (DPP4-I), is clinically used as an oral antidiabetic agent. This study was designed to investigate the effects of Sitagliptin, Silymarin, and their combination on established liver fibrosis in carbon tetrachloride (CCl4) rat model. Male albino rats received intraperitoneal injections of CCl4 three times a week for 7 weeks, as well as daily oral treatments of Sitagliptin (100mg/kg) or Silymarin (100mg/kg) or their combination during the 7 weeks of intoxication...

Worsening of glycemic control in type 2 Diabetes mellitus occur on account of declining beta cell function. This calls for up titration of the chosen drug, addition of another agent with complementary action and eventually insulin usually after 2 or three OADs. Introduction of insulin has many issues which include parenteral route of administration, cost and enhancement of hypoglycemic tendency. We propose the addition of another OAD in lieu of insulin in whom glycemic control can be achieved equally well without insulin...
