Definitions

  • the present invention relates to a process for the preparation of a film coated tablet comprising linagliptin and metformin HCI, so the process provides the desired stability and dissolution profile of the tablet.
  • the present invention also relates to a simple, rapid, cost effective, time-saving and industrially convenient process.
  • Diabetes mellitus is a group of disorders of carbohydrate metabolism in which the action of insulin is diminished or absent through altered secretion, decreased insulin activity or a combination of both factors.
  • Type 1 and Type 2 There are two main types of diabetes; Type 1 and Type 2:
  • Type 1 diabetes occurs because the insulin-producing cells of the pancreas (beta cells) are damaged. In Type 1 diabetes, the pancreas makes little or no insulin, so sugar cannot get into the body's cells for use as energy. People with Type 1 diabetes must use insulin injections to control their blood glucose.
  • Type 2 diabetes the pancreas makes insulin, but it either doesn't produce enough, or the insulin does not work properly. This diabetes occurs most often in people who are over 40 years old and overweight. Type 2 diabetes may sometimes be controlled with a combination of diet, weight management, and exercise. However, treatment also may include oral glucose-lowering medications or insulin injections.
  • Linagliptin is used for type 2 or non-insulin dependent diabetes. It is a selective, orally administered, xanthine based dipeptidyl peptidase-4 (DPP-4) inhibitor used as an adjunct to diet and exercise to improve glycemic control. DPP-4 inhibitors work by blocking the action of DPP-4, an enzyme which destroys the hormone incretin.
  • DPP-4 inhibitors work by blocking the action of DPP-4, an enzyme which destroys the hormone incretin.
  • DPP-4 inhibitors work by blocking the action of DPP-4, an enzyme which destroys the hormone incretin.
  • GLP-1 glucagon-like peptide-1
  • GIP glucose-dependent insulinotropic peptide
  • Linagliptin 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.
  • linagliptin 8-[(3R)-3-aminopiperidin-1-yl]-7-but-2-yn-1-yl)-3-methyl-1- [(4-methylquinazolin-2-yl)methyl]-3,7-dihydro-1 H-purine-2,6-dione and its chemical structure is shown in the Formula I.
  • Metformin is antidiabetics having an orally-administrated biguanide structure.
  • Metformin hydrochloride is a white to off-white crystalline compound and it is freely soluble in water and practically insoluble in acetone, ether and chloroform.
  • Oral doses of metformin are generally recommended in the range of 500 to 2500 mg a day and a single dose may vary from 500 to 850 mg. It is used singly or in combination with sulfonylureas, alpha-glucosidase inhibitors, or insulin.
  • metformin hydrochloride is 1 ,1-dimethylbiguanide hydrochloride, has the following chemical structure of Formula II.
  • a combination therapy of linagliptin with metformin HCI provides an even more effective treatment of type II diabetes.
  • Linagliptin in combination with Metformin is marketed in the United States under the brand name Jentadueto ® by Boehringer Ingelheim.
  • U.S. Patent Application No. US 20130122089 discloses a pharmaceutical composition comprising linagliptin with mannitol, pregelatinized starch, copovidone, cornstarch, and magnesium stearate.
