Definitions

• the present invention relates to a pharmaceutical composition
• a pharmaceutical composition comprises a granulate comprising empagliflozin or salts thereof and linagliptin or salts or crystalline polymorph thereof, wherein the granulate is obtained by hot melt extrusion.
• 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 overweighed. 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.
• the chemical name of linagliptin is 8-[(3R)-3-aminopiperidin-1-yl]-7-but-2-yn-1-yl)-3-methyl-1- [(4-methylquinazolin-2-yl)methyl]-3,7-dihydro-1H-purine-2, 6-dione and its chemical structure is shown in the Formula I.
• Empagliflozin is a known SGLT2 inhibitor that is described for the treatment or improvement in glycemic control in patients with type 2 diabetes mellitus.
• the chemical name of empagliflozin is 1 -chloro-4-(3-D-glucopyranos-1 -yl)- 2-[4-((S)-tetrahydrofuran-3-yloxy)- benzylj-benzene and its chemical structure is shown in the Formula II.
• Tablets of empagliflozin in combination with linagliptin for oral administration are currently being marketed in United States under the name Glyxambi® by Boehringer Ingelheim indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus and are available as single layer tablets in two dosage strengths i.e. 10 mg/5 mg and 25 mg/5 mg respectively.
• Patent publication describes pharmaceutical compositions of linagliptin, their preparation and their use in the treatment of type 1 diabetes mellitus and type 2 diabetes mellitus.
• Patent publication discloses single layered pharmaceutical compositions comprising combination of empagliflozin and linagliptin.
• a pharmaceutical composition comprising empagliflozin or salts thereof and linagliptin or salts or crystalline polymorph thereof in oral pharmaceutical dosage forms.
• the main object of the present invention is to provide a pharmaceutical composition comprising empagliflozin or salts thereof and linagliptin or salts or crystalline polymorph thereof having the desired content uniformity and the desired dissolution profile by the help of selection of excipients using an effective process and bringing additional advantages to the relevant prior art.
• the content uniformity of low dose drugs in dosage forms is very important for quality assurance.
• the advantages of the present invention are even more significant, as the problem of homogeneity is even more likely to occur when two active substances are incorporated in one final dosage form, especially when two actives is used very different regarding the amount.
• Improved content uniformity efficiently contributes to a marked increase in bioavailability.
• Improved content uniformity also favors to avoid toxicity in the otherwise possible event that the amount of drug substance would be too high.
• Linagliptin is used small proportion that can lead to important problems during the process of the formulation. This causes the content uniformity problems and this causes dissolution problem.
• using hotmelt extrusion process provides homogeneity and content uniformity which would not lead to losses in the linagliptin or excipients during production.
