Definitions

  • the present invention relates to new rosuvastatin formulations prepared so as to be used in the treatment of hyperlipidemia.
  • the characteristic features of the formulations are that said formulations comprise rosuvastatin on effective amounts; a pharmaceutically acceptable phosphate salt is used as the stabilizer, and the ratio of rosuvastatin to the stabilizer in the formulation is in the range of 0.5-20 by weight.
  • Rosuvastatin which has the chemical name (3i?,5S,6E)-7-[4-(4-fluorophenyl)-6-(l-methylethyl)-2[methyl(methylsulphonyl)amino]-5- pyrimidinyl]-3,5-dihydroxy-6-heptenoic acid is a HMG Co A enzyme inhibitor and it is displayed in formula (I):
  • rosuvastatin which is displayed in formula (I) in the patent numbered US5260440, inhibits the activation of the enzyme named HMG-CoA reductase that is responsible for cholesterol synthesis in the body and prevents cholesterol formation and it is effective in the treatment of hypercholesterolemia, hyperlipoproteinemia and atherosclerosis.
  • Statin derivative cholesterol absorption inhibitors can also be used in combination with cardiovascular active agents; for instance fibric acid derivatives, calcium channel blockers and cholesterol absorption inhibitors.
  • rosuvastatin easily disintegrates as affected by factors such as moisture and light, and this constitutes a serious impediment to development of stable rosuvastatin formulations and combinations.
  • Rosuvastatin calcium is transformed into lactone as a result of "intramolecular esterification" which occurs between carboxylic acid in its structure and hydroxyl groups on ⁇ and ⁇ carbons of this carboxylic acid.
  • the reaction takes place in acidic environment and the basic agents cause the reaction to revert back.
  • the main disintegration products (3R, 5S) that arise as a result of the disintegration of rosuvastatin are lacton and oxidation products.
  • Richter Gedeon NYRT disclosed formulations comprising rosuvastatin calcium as the active agent and calcium acetate, magnesium hydroxide, calcium gluconate, calcium glycerophosphate or aluminum hydroxide as the stabilizing agent in the patent application WO2008035128(Al).
  • the first aspect of the invention relates to an enhanced pharmaceutical formulation comprising rosuvastatin in a therapeutically effective amount and a pharmaceutically acceptable phosphate salt as the stabilizer.
  • the invention discloses stable rosuvastatin formulations which have longer shelf life than known formulations and in which the ratio of rosuvastatin to the stabilizer is in the range of 0.5- 20 by weight.
  • the characteristic feature of the formulations is that said formulations comprise rosuvastatin in an effective amount, a pharmaceutically acceptable phosphate salt and or pharmaceutical derivatives thereof, and the ratio of rosuvastatin to the stabilizer is in the range of 0.5-20 by weight.
  • Another characteristic feature of the formulations of the present invention is that the ratio of rosuvastatin to the stabilizer used in said formulations is preferably in the range of 0.5-15, more preferably in the range of 0.5-8 by weight.
  • phosphate salt used throughout the text comprises phosphate salts and all pharmaceutically acceptable derivatives thereof. 'Derivatives' refers to all pharmaceutically acceptable hydrates and antihydrates of said phosphate salt.
  • Said phosphate salts can be selected from a group comprising monobasic, dibasic or tribasic calcium, magnesium, aluminum, iron phosphate salts and/or hydrates thereof.
  • the preferred phosphate salt is in dihydrate form though it is more preferably dibasic calcium phosphate dihydrate and/or pharmaceutically acceptable derivatives thereof.
