Definitions

• the present invention relates to a pharmaceutical combination comprising sitagliptin or a pharmaceutically acceptable salt thereof in combination with a PPAR dual agonist or a pharmaceutically acceptable salt thereof and at least one pharmaceutically acceptable excipient.
• Sitagliptin is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. It is an oral antihyperglycemic of the dipeptidyl peptidase-4 (DPP-4) inhibitor class.
• DPP-4 inhibitors work by blocking the action of DPP-4, an enzyme which destroys the hormone incretin.
• DPP-4 dipeptidyl peptidase-4
• Sitagliptin works by binding to DPP-4 and preventing it from breaking down the GLP-1 and GIP. This increases the levels of these hormones in the body and so increases their effect on controlling blood sugar.
• Sitagliptin is licensed as its phosphate monohydrate salt in the US and EU under the name of JANUVIA in the strength of 100 mg, 50 mg, and 25 mg. The recommended dose is 100 mg once daily.

• HMG-CoA reductase inhibitor combination indicated in patients for whom treatment of hypercholesterolemia and type 2 diabetes mellitus.
• sitagliptin and PPAR dual agonists in prior art or in the market for the treatment of cardiovascular disease in patients with type-2 diabetes mellitus.
• Sitagliptin increases plasma GLP-1 concentration and elevate cellular cAMP levels in pancreatic beta-cells leading to potentiate insulin secretion, whereas PPAR agonists regulate lipid homeostasis, cellular differentiation, proliferation and the immune response. Therefore, it is anticipated that a combination therapy of sitagliptin and PPAR agonists may synergistically represents a novel approach to modifying metabolic risk factors associated with adverse cardiovascular outcomes in patients with type 2 diabetes.
• PPAR agonists are drugs which act upon the peroxisome proliferator-activated receptor. Over the last decade, the members of the peroxisome proliferator-activated receptor (PPAR) subclass have emerged as valuable pharmacological targets whose activation can normalize metabolic dysfunctions and reduce some cardiovascular risk factors associated with type-2 diabetes mellitus.
• PPAR peroxisome proliferator-activated receptor
• PPARa alpha
• PPARy gamma
• PPAR5 delta
• dual acting PPARa/ ⁇ alpha/gamma
• PPAR pan alpha/delta/gamma
• PPAR alpha agonists are used for dyslipidemia to increase HDL (High Density Lipoprotein), decrease TG (Triglycerides) without effect on LDL (Low Density Lipoprotein).
• PPAR gamma agonists are insulin sensitizers for type 2 diabetes.
• PPAR delta agonists are developed to deal with glucose resulting in insulin resistance and diabetes.
• PPAR dual (alpha and gamma) agonists are for combined treatment of type 2 diabetes and dyslipidemia.
• PPAR pan (alpha/delta/gamma) agonists are for combined treatment of type 2 diabetes and dyslipidemia.
• PPAR alpha agonists are also known as glitazones or thiazolidinediones (TZDs). They comprise pioglitazone, rosiglitazone, ciglitazone, darglitazone, englitazone, lobeglitazone, mitaglitazone, netoglitazone and troglitazone.
• PPAR gamma agonists (also known as fibrates) comprise bezafibrate, ciprofibrate, clofibrate, gemfibrozil, fenofibrate, simfibrate, lifibrate, pirifibrate, theofibrate, tiafibrate, timofibrate, tocofibrate.
• PPAR delta agonists comprise endurobol.

• PPAR dual agonists are the glitazars that combine increased insulin sensitization with lipid control. They bind and activate both the alpha and gamma PPAR isoforms and improvement is achieved both in lipid profiles and insulin sensitization while avoiding dyslipidemia and weight gain.
• Glitazars are ideally suitable drugs in treatment of type 2 diabetic patients who have cardiovascular risk secondary to elevated triglyceride concentration. These molecules do not only target the dyslipidemia but also contribute to improved glycemic control.
• Lipaglyn recommended in strength of 4 mg, developed by the Zydus Cadila. Lipaglyn has been approved for the treatment of Type II diabetes by the Drug Controller General of India in 2013.
