Definitions

  • the present invention relates to a solid oral preparation of febuxostat and process for preparation thereof. More particularly, it relates to a solid oral preparation of febuxostat which is stable and has desired pharmacokinetic properties.
  • Febuxostat is administrated in the form of tablets that are marketed in the USA and the EU under the name ULORIC® for the chronic management of hyperuricemia patients with gout.
  • U.S. Patent No. 6225474 and International publication WO 99/65885 discloses six crystalline forms of febuxostat viz. crystal A, crystal B, crystal C, crystal D, crystal G and amorphous form of Febuxostat. It is described that crystals A, C and G are useful in view of retention of a crystal form in long term storage. Among them, crystal A is preferred in view of industrial superiority.
  • the selection of polymorph or its particle size for its use in preparing any pharmaceutical composition is critical as that decides the processing properties, such as in case of handling, processing, storage stability, purification etc of the material in any formulation.
  • a right choice of polymorph of a pharmaceutically useful compound can also provide an opportunity to improve the performance characteristics of a pharmaceutical product. It may increase the choices in hand for a scientist working on formulation optimization, for example, by providing a product with different properties e.g. better processing or handing characteristics, improved dissolution profile, or improved shelf life etc.
  • U.S. Pat. No. 7361676 discloses a tablet formulation comprising crystal-A which is stated as stable and having little variation in the dissolution profiles.
  • Patent stated that it is not always possible to obtain preparations having no-variation in the dissolution profiles of drugs, even if such a crystal form is used as is thought to be most stable in a physical stability test.
  • Prior art discloses various crystal forms of febuxostat, but, only crystal A has been used in tablet formulation.
  • solubility of form A is limited, as it has a value of 0.22 mg/ml. Therefore, to get the desired pharmacokinetic profile; drug crystals were required to be present in diameter range of 12.9 to 26.2 ⁇ , as only this particular particle size range would give the desired results of consistency in disintegration time, uniformity of content, CV values and friability of the tablet, against a tablet with particle size outside this range.
  • form-A is difficult to make as form A is said to be obtainable in pure form only in a quite narrow window of temperature and methanol / water ratio in the region I as shown in Fig 1 of EP 1020454.
  • the process to obtain pure form A is especially critical, as different polymorphic forms of Febuxostat are obtainable from the same solvent system.
  • Form-G of Febuxostat is such a crystal that has simpler and economic process of manufacturing and can be used in the formulation to give desired pharmacokinetic properties.
  • the principal object of the present invention is to provide a solid preparation of the febuxostat which is stable and has desired pharmacokinetic properties.
  • Another object of the present invention is to provide a solid preparation of the febuxostat, which uses crystal form-G, and still is stable and has desired pharmacokinetic properties.
  • the present invention provides a stable solid oral preparation comprising; micronized febuxostat Form-G along with one or more pharmaceutically acceptable excipients.
  • a process for preparation of stable solid oral preparation comprises the steps of; i) mixing micronized febuxostat form-G with one or more of pharmaceutically acceptable excipients; and ii) formulating the mixture of step (i) into suitable dosage form.
  • FIG 1 is a graph showing dissolution profile comparison of Innovator product 'Reference' (Uloric ® 80mg) and Alembic product 'test' (Febuxostat Tablets 80mg) in media; 0.05 M (pH 6.8) Potassium Phosphate Buffer/ Paddle/ 75 rpm/ 900 ml
  • the present invention relates to a solid oral preparation of febuxostat and to a process for preparation thereof. More specifically, the present invention relates to a solid oral preparation which comprises febuxostat form-G, which may further be micronized.
  • Micronization is the process of reducing the average diameter of a solid material's particles.
  • any of conventional methods including but not limited to, such as milling, grinding, crushing, cutting or modern techniques such as RESS process (Rapid Expansion of Supercritical Solutions), the SAS method (Supercritical Anti- Solvent) and the PGSS method (Particles from Gas Saturated Solutions) can be used.
  • the crystals of the febuxostat can be produced by the method described in, for example, international publications viz. WO 92/09279 and WO 99/065885.
  • present invention provides a stable solid oral preparation comprising; micronized febuxostat form-G along with one or more pharmaceutically acceptable excipients.
  • micronized refers to febuxostat form-G having preferably particle size distribution of; D 90 less than 30 ⁇ , D 50 less than 1-5 ⁇ and D 10 less than 1 ⁇ .
  • the average particle diamter can be 3 ⁇ or greater and 30 ⁇ or less (as determined by an image analysis)
