  • Glucose also serves as a building block for larger structural molecules of the body, such as glycoproteins and glycolipids.
  • the human body tightly regulates glucose levels. Abnormally high or low levels result in serious, potentially life-threatening complications such as cardiovascular disease, stroke, chronic kidney disease, foot ulcers, damage to the nerves, damage to the eyes, cognitive impairment.
  • Type 2 diabetes is the most common form of diabetes. It was once called adult-onset diabetes because it typically begins in middle or older age. But more and more teens and young adults are also developing it now a day due to increased obesity.
  • Dipepidyl peptidase-4 (DPP-4) inhibitors represent a class of agents that are being developed for the treatment or improvement in glycemic control in type 2 diabetes.
  • DPP-4 inhibitors include sitagliptin, vildagliptin, saxagliptin, linagliptin, and alogliptin.

  • Cadila also reported a crystalline form and its process in PCT patent application WO2012/147092.
  • Sitagliptin hydrochloride monohydrate is freely soluble in water and thus polymorph and particle size are not expected to be important aspects in the present formulation development.
  • the tablet composition also contains one or more inert materials known as excipients.
  • the primary composition includes diluents, disintegrants and lubricants.
  • Other excipients which give physical characteristics to the finished tablet are coloring agents, and flavors in the case of chewable tablets.
  • excipients are selected to impart good flow and compression characteristics to the material being compressed. Excipients are also selected with the perspective to enhance dissolution, physicochemical characteristics, and stability of the drug substance in the final dosage form.
  • Formulation trials were performed using both direct compression (dry mixing) and wet granulation methods to study the physicochemical properties as well as dissolution properties of the tablets.
  • Direct compression is regarded as a relatively quick process where the powdered materials are compressed directly without changing the physical and chemical properties of the drug.
  • the wet granulation method comprises an additional step of adding the granulating solution to the mixed powders to obtain a granulation.
  • direct compression is usually limited to those situations where the drug or active ingredient has physical characteristics required to form pharmaceutically acceptable tablets.
  • dry granulation process presents very to extremely poor flowability and the compression was not feasible in the tableting machine. Comparably, the flowability of wet granulation process could be considered as acceptable. Therefore, wet granulation process is chosen for the current development.
  • Lubricant is an essential component of the tablet formulation. Some pharmaceutical scientists believe that the manner of which a lubricant is added to a formulation must be carefully controlled. Accordingly, lubricants are usually added to a granulation by gentle mixing. It is also believed that prolonged blending of a lubricant with a granulate can materially affect hardness and disintegration time for the resulting tablets. For these reasons, composition of the tablet core is divided into two phases, an internal and an external phase. Lubricants are to be used in the external phase of the tablet core to avoid prolonged blending with the excipients used in the internal phase.
  • the preferred formulation of this invention comprises Sitagliptin as the active ingredient, a combination of diluents and a disintegrant in the internal phase of the tablet core and lubricants in the external phase of the tablet core.
  • Diluents are added to solid pharmaceutical dosage forms to make the product large enough for swallowing and handling, and more stable.
  • a combination of microcrystalline cellulose and dibasic calcium phosphate anhydrous are used in the present invention as diluents.
  • Microcrystalline cellulose is available from several suppliers. Suitable microcrystalline cellulose includes Avicel PH 101, Avicel PH 102, Avicel PH 103, Avicel PH 105 and Avicel PH 200, manufactured by FMC Corporation. Particularly preferred in the practice of this invention is Avicel PH 102, which has the smallest surface area and pore structure.
  • Anhydrous form of calcium phosphates is often used to overcome the problems related to dihydrate form.
  • Microcrystalline cellulose and dibasic calcium phosphate anhydrous are used in equal amounts. The sum of microcrystalline cellulose and dibasic calcium phosphate anhydrous may be present in an amount preferably from about 40% to about 80% by weight, more preferably from about 50% to about 75% by weight, and most preferably from about 60% to
  • Disintegrants are included to ensure that the tablet has an acceptable rate of disintegration.
  • examples of pharmaceutically acceptable disintegrants include, but are not limited to, starches; clays; celluloses; alginates; gums; cross-linked polymers, e.g., cross-linked polyvinyl pyrrolidone, cross-linked calcium carboxymethylcellulose and cross-linked sodium carboxymethylcellulose (croscarmellose sodium); soy polysaccharides; and guar gum, sodium starch glycolate.
  • Croscarmellose sodium is the preferred disintegrant used in the present invention. It may be present in an amount from about 1% to about 20%, more preferably from about 3% to about 14% by weight of the composition, and most preferably from about 5% to about 8% by weight of the composition.
  • Lubricants are typically added to prevent the tableting materials from sticking to punches, minimize friction during tablet compression and allow for removal of the compressed tablet from the die.
  • pharmaceutically acceptable lubricants include, but are not limited to, colloidal silica, magnesium trisilicate, starches, talc, tribasic calcium phosphate, magnesium stearate, aluminum stearate, calcium stearate, magnesium carbonate, magnesium oxide, polyethylene glycol, powdered cellulose and microcrystalline cellulose.
  • the lubricant component may be hydrophobic or hydrophilic.
  • Sodium stearyl fumarate is a water-soluble lubricant. It is usually preferred for better taste.
  • Magnesium stearate is also selected for the present invention. It aids in the flow of the powder in the hopper and into the die. It is stable and does not polymerize within the tableting mix.
  • Formulation development was mainly carried out on Sitagliptin lOOmg film-coated tablet and final formula was extrapolated linearly to produce the other strengths (25mg and 50mg). All 100 mg film-coated tablets were prepared by using a round (10 mm) slightly biconvex tablet punch.
  • composition of example 1 was prepared with both dry mixing and wet granulation. More specifically, Composition 1 and Composition 2 are identical and differ only to the method of their manufacturing.
  • Composition 1 was prepared by Dry mixing according to the following steps:
  • API microcrystalline cellulose, dibasic calcium phosphate anhydrous and croscarmellose sodium are sieved through a 16 mesh size sieve and they are mixed for 10 min.
  • Magnesium Stearate is sieved through a 30 mesh size sieve and it is mixed with above blend for 3 min.
  • Composition 2 was prepared by wet granulation according to the following steps:
  • API microcrystalline cellulose, dibasic calcium phosphate anhydrous and croscarmellose sodium are sieved through a 16 mesh size sieve and they are mixed for 10 min.
  • Magnesium Stearate is sieved through a 30 mesh size sieve and it is mixed with above blend for 3 min.

  • the dry mixing tablets exhibit acceptable values; however, the values are close to the lower limits of target characteristics.
  • the wet granulation process tablets are characterized by slightly higher disintegration time, which does not comply with target characteristics, but could be further optimized.
  • the main difference between the two processes appears in blend properties. More particularly, the Carr’s Index is high enough for both Trials, but the dry mixing blend presents a very poor - extremely poor flowability and the compression was not feasible in the tableting machine. Such powders with extremely poor flowability cannot be adequately compressed.
  • the flowability of wet granulation process could be considered as acceptable and that conclusion was reinforced by the smooth tablet machine operation during compression step. Therefore, wet granulation process was used for further development.
  • the disintegration time for Composition 2 does not comply with target characteristics. An even higher time is expected for coated tablets.
  • the disintegrant percentages tested were 2.0%wt in Comp 2, 3.5%wt in Comp 2.1, 5.0%wt in Comp 2.2, 6.5%wt in Comp 2.3 and 8.0%wt in Comp2.4.
  • the quantities of the diluents (microcrystalline cellulose & dibasic calcium phosphate anhydrous) were modified equally so that the weight of the final tablets remain the same among all formulation trials. Table 4 below displays the characteristics of the resulting tablets.
  • the dissolution rates indicate that the proportional increase of croscarmellose sodium quantity does affect the dissolution profiles. According to the above, the specification of >85% release at 15 min is fulfilled for disintegrant percentages > 5.0% and a range of 5.0 - 8.0% for disintegrant used is preferably selected.
