Definitions

  • the present invention relates to preparations of stable pharmaceutical compositions comprising nateglinide Form B, and processes for their preparation.
  • Nateglinide is an amino acid derivative that lowers blood glucose levels by stimulating insulin secretion from the pancreas. It is widely indicated as monotherapy to lower blood glucose in patients with Type 2 diabetes. It is also indicated for use in combination with metformin.
  • Presently nateglinide oral tablets are available in 60 mg or 120 mg strengths and are marketed by Novartis under the trade name STARLIX®.
  • Nateglinide is disclosed in Japanese Patent Application Laid Open No. 63-54321 (equivalent to EP-A-196222 and US 4,816,484) and in J. Med. Chem. 32, 1436.

  • the known B-type crystals suffer from problems of instability, especially when subjected to pulverization. The instability results in conversion of the B-type crystals into other forms.
  • US 5,463,116 discloses a method of producing a crystalline form of nateglinide having improved stability (H Type) to pulverization, and is thus said to be more suitable for use in dosage forms than those of the B-type.

  • nateglinide Form B converts to other polymorphic forms.
  • compositions comprising nateglinide Form B, when prepared by granulation with isopropyl alcohol, are stable even after pulverization, i.e., there is no conversion of Form B to any other polymorphic form even when stored at accelerated aging conditions of temperature.
