Containing Discrete Coated Particles Pellets, Granules, Or Beads Patents (Class 424/458)
  • Patent number: 7727553
    Abstract: The present invention provides oral preparations with good disintegration containing a slightly water-soluble active ingredient, which comprise a mixture of a solid formed product (e.g. a granule) and a second disintegrant wherein said solid formed product comprises a slightly water-soluble active ingredient, a first disintegrant and a water-soluble excipient which is formed by using a water-soluble polymer binder; or comprises a solid formed product prepared from a slightly water-soluble active ingredient, a disintegrant and a sugar alcohol by using a water-soluble polymer binder. When orally administered, these oral preparations exhibit excellent dissolution characteristics of the active ingredient in the digestive tract, and further, these preparations can show equivalent dissolution profile even at different amounts of the active ingredient, and thus enable the selection of the most suitable medicament for each patient, which makes these preparations highly useful in the clinical field.

The invention relates to the use, in an oral pharmaceutical form comprising losartan, of a coating or matrix including said losartan and allowing controlled release of said losartan, such that this form orally administered to a sample of individuals leads, irrespective of the fed or fasted state of the individuals, to a reduction of the interindividual standard deviation of the Cmax, which ensures lower variability of the efficacy and of the therapeutic safety of the pharmaceutical form relative to an immediate-release pharmaceutical form of losartan administered to this same sample of individuals, at the same dose. Another aim of the invention is to provide an oral pharmaceutical form of losartan that can be administered once a day and that is just as effective as the “one dose intake per day” forms and the “two dose intakes per day” forms.
