Definitions
- the present invention relates to a pharmaceutical tablet formulation comprising metformin and sitagliptin and at least one surfactant. Further the present invention provides a method for the preparation of said composition.
- 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.
- 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 250 to 1000 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 I.
- metformin Although metformin is effective at lowering blood glucose levels, its use is associated with gastrointestinal (Gl) adverse effects, particularly diarrhea and nausea. These adverse effects may limit the tolerated dose of metformin and cause patients to discontinue the therapy.
- Gl gastrointestinal
- 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
- GLP-1 glucagon-like peptide-1
- GIP glucose-dependent insulin tropic peptide
- 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 (3R)-3-amino-1-[3-(trifluoromethyl)-6,8-dihydro-5H- [1 ,2,4]triazolo[4,3-a]pyrazin-7-yl]-4-(2,4,5-trifluorophenyl) butan-1-one or (2R)-4-oxo-4- [3- (trifluoromethyl)-5,6-dihydro[1 ,2,4]triazolo[4,3-a]pyrazin-7(8H)-yl]-1-(2,4,5trifluorophenyl) butan-2-amine) and its chemical structure is shown in the Formula II.
- Sitagliptin is disclosed in the patent US 6699871.
- a crystal phosphate monohydrate form of sitagliptin is disclosed in the patent WO 2005003135.
- DPP-4 inhibitors especially sitagliptin have a novel mechanism of action and many studies are available which shows their efficacy and safety in therapies/medication are available.
- the single sitagliptin alone does not provide adequate glycemic control.
- Sitagliptin increases plasma GLP-1 concentration and elevates cellular cAMP levels in pancreatic beta-cells leading to potentiate insulin secretion, whereas metformin improves glucose tolerance in patients with Type 2 diabetes, lowering both basal and postprandial plasma glucose. Its pharmacologic mechanisms of action are different from other classes of oral antihyperglycemic agents in that metformin decreases hepatic glucose production, decreases intestinal absorption of glucose and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. Therefore, they both help to reduce blood glucose levels in different pathways in type 2 diabetes patients.
- a tablet formulation for metformin and sitagliptin combination is commercially available under the trade name Janumet®. It contains either 500 or 1000 mg metformin, and 50 mg sitagliptin.
- Pharmaceutical compositions comprising fixed-dose combinations of immediate- release sitagliptin and metformin are disclosed in WO 2007/078726 patent application which published on July 12, 2007.
- U.S. publication number 2012/0202820 discloses pharmaceutical compositions comprising sitagliptin and metformin in combination with a lubricant wherein the lubricant is polyethylene glycol or mixtures of polyethylene glycol with one or more other lubricants and comprises more than 10% by weight of the total weight of the composition.
- Sitagliptin and metformin combination has incompatibility and stability problems due to interactions between drug substances.
- the tablet in which sitagliptin and metformin are in different compartments is formulated so as to overcome the problems.
- metformin and sitagliptin do not interact with each other, but also this provides easy and cost-effective process.
- the main object of the present invention is to avoid incompatibility problems between metformin and sitagliptin using the tablet having different compartments.
- Another object of the present invention is to provide improved stability and desired dissolution rate in tablet formulation.
- Another object of the present invention is to provide compressible property of metformin.
- metformin includes metformin and pharmaceutically acceptable salts thereof.
- the pharmaceutically acceptable salts include hydrochloride, hydrobromide, fumarate, malonate, malate, succinate, lactate, glycolate, maleate, citrate, and aspartate.
- the pharmaceutically acceptable salts of metformin may be present in hydrous or anhydrous forms. They may also be present in crystalline or amorphous forms. In this invention, preferably metformin hydrochloride is used.
- sitagliptin includes sitagliptin and pharmaceutically acceptable salts thereof.
- the pharmaceutically acceptable salts include hydrochloride, hydrobromide, phosphate, sulphate, mesylate, besylate, fumarate, malonate, malate, succinate, lactate, glycolate, maleate, citrate, and aspartate.
- the pharmaceutically acceptable salts of sitagliptin may be present in hydrous or anhydrous forms.
- the hydrate forms may be monohydrate or dihydrate forms.
- the pharmaceutically acceptable salts of sitagliptin may also be present in crystalline or amorphous forms. In this invention, preferably sitagliptin malate is used.
- the term "compartment” used herein throughout the specification is used to intend a part of the dosage form comprising one or both of metformin and sitagliptin, and optionally together with pharmaceutical excipients.
- the part of the dosage form may be in the form of a layer or core or tablet.
- the forms may be formed by coating or compression.
- core refers to a compact mass having a definite geometric shape such as tablets, granules, pellets, capsules.
- Sitagliptin and metformin combination has incompatibility and stability problems due to interactions between drug substances. Separating metformin and sitagliptin in such a way that their interaction is eliminated is an effective solution so as to overcome these problems.
- the tablet is designed by placing these two drug substances in different compartments that solves the interaction problems. Furthermore, this is an easy and cost-effective process and this provides improvement in dissolution profile with using certain excipients.

- Metformin is known to be very poorly compressible active substance for tableting process. As it is highly crystalline and has poor compaction properties, it is difficult to form tablets by direct compression or dry granulation. Metformin further, is a high dose drug that is hard to compress directly into tablets. On the other hand, it is known that conventional methods of dry granulation fail to provide a satisfactory solution to poor compaction properties of metformin. It has been found that desired stability and improved dissolution may be obtained when metformin and sitagliptin are formulated in wet granulation process.
