Definitions

  • the present invention relates to a pharmaceutical composition containing l'-[4-[l-(4- fluorophenyl)-lH-indole-3-yl]-l-butyl]-spiro[isobenzofirran-l(3H),4'-piperidine] as the active ingredient.
  • the present invention relates to a solution of the active ingredient, which is contained in a capsule.
  • the compound of formula I and pharmaceutically acceptable salts thereof have a poor aqueous solubility, although the hydrohalogenides of the compound of formula I have improved aqueous solubility compared to other salts of the compound.
  • bioavailabihty of the compound of formula I shows a high degree of variation when the compound is administered in the form of a conventional tablet prepared by simple compression of the active ingredient and pharmaceutically acceptable excipients.
  • Micronisation of the compound of formula I was expected to improve bioavailabihty, but was found not to markedly improve the bioavailabihty of the compound. In addition, it was found that food intake had a pronounced effect on the bioavailabihty of the compound, which leads to undesirable variations of the blood serum level of the active compound.
  • the present invention relates to a pharmaceutical composition of the compound of formula I comprising a solution of the compound of formula I or a pharmaceutically acceptable salt thereof in a liquid, semi-solid or solid solvent system comprising polyethylene glycol and optionally a solubility enhancer.
  • the pharmaceutical composition of the invention comprises a solution of the compound of formula I in a solvent system comprising polyethylene glycol and up to 20 % w/w of a solubility enhancer.
  • the present invention relates to such solutions, which are contained in a capsule.
  • the molecular weight of the polyethylene glycol used affects the properties of the resulting solution of the invention.
  • polyethylene glycol having an average molecular weight from about 200-800 daltons, preferably from about 400-600 produces a solution, which is liquid.
  • the present invention relates to solutions as above wherein the solvent system is liquid at room temperature.
  • the polyethylene glycol is selected from polyethylene glycols with an average molecular weight of 400-600 (PEG 400 - PEG 600).
  • the present invention also relates to such liquid solutions, which may be contained in a soft capsule, preferably a soft gelatine capsule, or in a modified hard gelatine capsule..
  • Polyethylene glycols do not dissolve the gelatin capsule material and may therefore be used as a vehicle in gelatin capsule formulations. However, it is important that a suitable amount of the active ingredient can be completely dissolved in a volume of solvent small enough to be contained in a capsule of a size, which is acceptable to patients. It may thus be necessary to add a solubility enhancer or co-solvent to the polyethylene glycol phase to obtain complete dissolution of the active ingredient.
  • the solubility enhancers or co-solvents useful according to the invention are suitably more hydrophilic than the polyethylene glycol used and such an enhancer could suitably be a short chain alcohol. Such solubility enhancers will typically be less compatible with the gelatin capsule material than the polyethylene glycol. However, according to the present invention, it has been found that the amount of solubility enhancer to be added to the solution may be kept below the amount, which causes degradation, etc. of the gelatin capsule.
  • Suitable solubility enhancers or co-solvents used according to the invention are propyleneglycol, ethyleneglycol, glycerol, sorbitol, transcutol and low molecular alcohols.
  • the solubility enhancer is propyleneglycol, sorbitol, ethanol and /or glycerol.
  • solubility enhancer which may be added to the polyethylene glycol phase without causing degradation of the gelatine capsule, will depend on the solubility enhancer chosen.
  • the amount of solubility enhancer is kept below 20% w/w.
  • solubility enhancer When propylene glycol is used as the solubility enhancer, the amount of solubility enhancer is suitably up to 10% w/w, preferably about 5% w/w.
  • Peroxidation of the polyethylene glycol may lead to oxidation of the active ingredient, as well as oxidation of the gelatin in the capsule shell causing gelatin cross-linking, and it may be preferred to add an antioxidant to the composition of the invention.
  • the antioxidant used may be any antioxidant, which is pharmaceutically acceptable.
  • the antioxidant is selected from alpha-tocopherol, BHA (2-tert-butyl-4-methylphenol) or BHT (2,6-di-tert-butyl-4-methylphenol), propylgallate, ascorbylpalmitate and other antioxidants well-known in the art.

  • the solutions according to the invention may contain up to 27 mg/ml of compound II.
  • the solutions of the invention are prepared by heating the polyethylene glycol, the solubility enhancer, the antioxidant and other excipients in a vessel fitted with an agitator.
