Definitions

  • the present invention relates to crystalline salts of flibanserin, 1-[2-(4-(3-trifluoro-methyl-phenyl)piperazin-1-yl)ethyl]-2,3-dihydro-1H-benzimidazol-2-one, to a process for their manufacture, to pharmaceutical formulations containing them and to their use as medicament.
  • the aim of the invention is to provide new forms of flibanserin with advantageous properties for pharmaceutical use.
  • the absorption of moisture reduces the content of pharmaceutically active substance as a result of the increased weight caused by the uptake of water.
  • Pharmaceutical compositions with a tendency to absorb moisture have to be protected from moisture during storage, e.g. by the addition of suitable drying agents or by storing the drug in an environment where it is protected from moisture.
  • the uptake of moisture may reduce the content of pharmaceutically active substance during manufacture if the pharmaceutical substance is exposed to the environment without being protected from moisture in any way.
  • a pharmaceutically active substance should be, if at all, only slightly hygroscopic.
  • the solubility of the active substance Another criterion which may be of exceptional importance under certain circumstances depending on the choice of formulation or the choice of manufacturing process is the solubility of the active substance. If for example pharmaceutical solutions are prepared (e.g. for infusions) it is essential that the active substance should be sufficiently soluble in physiologically acceptable solvents. It is also very important for drugs which are to be taken orally that the active substance should be sufficiently soluble.

They may also contain suspension adjuvants or thickeners such as sodium carboxymethyl cellulose, wetting agents such as, for example, condensation products of fatty alcohols with ethylene oxide, or preservatives such as p-hydroxybenzoates.

  • suspension adjuvants or thickeners such as sodium carboxymethyl cellulose, wetting agents such as, for example, condensation products of fatty alcohols with ethylene oxide, or preservatives such as p-hydroxybenzoates.
  • Solutions for injection are prepared in the usual way, e.g. of with the addition of preservatives such as p-hydroxybenzoates, or stabilisers such as alkali metal salts of ethylenediamine tetraacetic acid, and transferred into injection vials or ampoules.
  • preservatives such as p-hydroxybenzoates, or stabilisers such as alkali metal salts of ethylenediamine tetraacetic acid
  • Capsules containing one or more active substances or combinations of active substances may for example be prepared by mixing the active substances with inert carriers such as lactose or sorbitol and packing them into gelatine capsules.
  • Suitable suppositories may be made for example by mixing with carriers provided for this purpose, such as neutral fats or polyethyleneglycol or the derivatives thereof.
  • the harvested crystals may be characterized by X-ray powder diffraction and thermal analysis (DSC). If suitable single crystals grow, single crystal X-ray structure analysis may be performed. The following equipment was used to characterize the crystalline salts forms.
  • XRPD patterns were obtained using a high throughput XRPD set-up.
  • the plates were mounted on a Bruker GADDS diffractometer equipped with a Hi-Star area detector.
  • the diffractometer was calibrated using Silver Behenate for the long d-spacings and corundum for the short d-spacings.
  • the data collection was carried out at room temperature using monochromatic CuK ⁇ radiation in the region of 2 ⁇ between 1.5 and 41.5°.
  • the diffraction pattern of each well was collected with an exposure time of 3-4 minutes.
  • Suitable single crystals were selected and glued to a glass fibre, which is mounted on a X-ray diffraction goniometer.
  • X-ray diffraction data were collected for the mounted crystals at a temperature of 233K using a KappaCCD system and MoK ⁇ radiation generated by a FR590 X-ray generator (Bruker Nonius Delft, The Netherlands).
  • Unit-cell parameters and crystal structure were determined and refined using the software package maXus (Mackay et al., 1997).
  • IGAsorp water sorption monitor from Hiden Isochema was used for the analysis of the hygroscopical behaviour at room temperature.
  • Solubility of the different crystalline salt forms in water was determined by adding approx. 5 mg of compound into 5 ml of water at room temperature. The mixture was vigorously shaken for 2 hours at room temperature. Afterwards the undissolved solid was removed by filtering through a 0.45 ⁇ m PTFE filter, in the filtrate the dissolved amount of compound was determined by UV-spectroscopy.
  • the process is illustrated by the following example of manufacturing process of the salts and crystalline salt forms, as can be done in parallel in 96 well assay plates (maximum volume of each well is about 200 ⁇ l).
  • the finely ground active substance, some of the corn starch, lactose, microcrystalline cellulose and polyvinylpyrrolidone are mixed together, the mixture is screened and worked with the remaining corn starch and water to form a granulate which is dried and screened.
  • the sodium-carboxymethyl starch and the magnesium stearate are added and mixed in and the mixture is compressed to form tablets of a suitable size.
  • the active substance, corn starch, lactose and polyvinylpyrrolidone are thoroughly mixed and moistened with water.
  • the moist mass is pushed through a screen with a 1 mm mesh size, dried at about 45° C. and the granules are then passed through the same screen.
  • convex tablet cores with a diameter of 6 mm are compressed in a tablet-making machine.
  • the tablet cores thus produced are coated in known manner with a covering consisting essentially of sugar and talc.
  • the finished coated tablets are polished with wax.
  • the substance and corn starch are mixed and moistened with water.
  • the moist mass is screened and dried.
  • the dry granules are screened and mixed with magnesium stearate.
  • the finished mixture is packed into size 1 hard gelatine capsules.
