Definitions

  • the present invention relates to a solid composition containing at least one pharmaceutically acceptable excipient and, as an active ingredient, rasagiline or a pharmaceutically acceptable salt thereof.
  • the invention further relates to a process for the preparation of this solid composition and to a pharmaceutical composition containing this solid composition.
  • Rasagiline the R (+) - enantiomer of N-propargyl-1-aminoindan
  • US Pat. No. 5,532,415 discloses the manufacture of rasagiline and various salts of this compound as well as the use of the drug for the treatment of a variety of diseases such as Parkinson's, memory disorders, dementia, depression, schizophrenia, hyperactivity, etc.
  • Another method for the production of Salts of rasagiline is disclosed in WO 2002/068376.
  • rasagiline is disclosed in EP-A-0 436 492 which discloses rasagiline and generally pharmaceutically acceptable acid addition salts thereof, specifically the hydrochloride and tartrate of rasagiline.
  • Further salts of rasagiline are described in WO 95/11016, namely the sulfate, phosphate, mesylate, maleate, esylate, acetate, fumarate, hydrobromide, tosylate and benzoate.
  • Further acid addition salts of rasagiline are described in WO 2008/019871.
  • Active ingredients are often mixed in pharmaceutical formulations in finely ground form as a powder with various adjuvants and optionally compressed after granulation to tablets.
  • the physical form of the active substance ie the polymorphic or amorphous form
  • the active ingredient mix well with the auxiliaries used and can be further processed.
  • a uniform distribution within the amounts of excipients used is necessary to ensure that, for example, tablets produced from the mixture each contain the same amount of active substance.
  • WO 2008/131961 which provides adsorbates which contain, in addition to a pharmaceutically acceptable, water-soluble, organic active ingredient, a pharmaceutically acceptable salt of rasagiline in amorphous form, deals with the problem of the stability of the physical form of the active substance rasagiline.
  • the adsorbates are prepared by spray-drying a solution of active ingredient and excipient. As a result, the active ingredient is adsorbed on the excipient particles, so that separate active and auxiliary phases are present.
  • WO 2006/091657 deals with the second problem of the homogeneous distribution of active ingredient particles in excipient mixtures.
  • a particularly uniform distribution of the active ingredient particles in an adjuvant mixture is achieved by milling the pharmaceutically acceptable salt of rasagiline such that more than 90% of the volume of the active ingredient particles has a size of less than 250 ⁇ m.
  • micronized drug particles have the disadvantage that it may come during grinding and further processing to electrostatic charging and agglomeration.
  • micronized active ingredients have a reduced flowability, so that this can lead to problems during further processing.
  • the form should optionally be able to process with other excipients easily to drugs and thereby ensure a uniform distribution of the drug and thus the uniformity of the active substance content in the drug.
  • the active ingredient form in the finished drug during the storage time in particular be physically stable.
  • the present invention thus relates to a solid composition containing at least one pharmaceutically acceptable excipient and, as an active ingredient, rasagiline or a pharmaceutically acceptable salt thereof, characterized in that the excipient and the active ingredient are present in a homogeneous, molecularly disperse mixture.
  • a homogeneous mixture is understood as meaning a solid solution of the active ingredient in the excipient.
  • the solid composition thus has only one phase, wherein the dissolved active ingredient is uniformly distributed in the excipient.
  • the homogeneous mixture thus contains at least substantially no phases of pure excipient or pure active ingredient.
  • the excipient and active ingredient are rather mixed together at the molecular level, so that neither visually nor with other physical methods phase boundaries between auxiliary and active substance can be observed. Accordingly, the active ingredient in the solid composition according to the invention is also present in neither crystalline nor amorphous form. The active ingredient is rather distributed at the molecular level between the molecules of the excipient.
  • the active substance can therefore no longer be detected by, for example, X-ray powder diffractograms but by spectroscopic methods such as, for example, confocal Raman spectroscopy.
  • pellets are produced from the samples, on the smooth surface of which a confocal mapping can be carried out.
  • the mappings are carried out in an area of 10 ⁇ m x 10 ⁇ m.
  • a NT-MDT NTEG RA-Spektra Nanofinder
  • Raman spectrometer with a maximum lateral resolution of ⁇ x, ⁇ y ⁇ 400 nm, height resolution ⁇ z ⁇ 700 nm, laser excitation 488 nm (Ar laser), 632.8 nm (HeNe laser).
  • the detector used is a PMT (photomultiplier tube).
  • the present invention also encompasses those solid compositions which still contain small amounts of undissolved drug particles. Such small amounts of undissolved particles do not disturb the advantageous properties of the composition according to the invention. In the solid composition, however, should less than 15 wt .-%, preferably less than 10 wt .-%, more preferably less than 5 wt .-% and particularly preferably less than 1 wt .-% of the total amount of the active ingredient in the form of particles.
  • composition according to the invention particularly preferably contains no active substance particles, in particular no active substance particles, which can be observed visually, for example under a light microscope, due to the phase boundaries between the active substance and the adjuvant occurring.
  • the solid composition according to the invention should therefore show a completely homogeneous image on visual inspection, in which no phase boundaries can be recognized.
  • the active ingredient is evenly distributed in the adjuvant and thus "prediluted".
  • the composition thus obtained can be processed either directly or, for example, with other excipients easily to drugs.
  • the composition of the invention allows a uniform mixing with other excipients, without a complex micronization would be necessary.
  • prediluting the active ingredient a homogeneous distribution in pharmaceutical formulations prepared therefrom and hence uniformity of the active ingredient content of these formulations are ensured. This facilitates, for example, the production of 200 mg tablets containing only 1 mg of rasagiline.
  • Another advantage of the composition of the invention is that the molecular disperse distribution of the active ingredient in the excipient accelerates the dissolution of the active ingredient. This may be important, for example, if a rasagiline salt which is sparingly soluble in water or at least less soluble, for example rasagiline tartrate, is used.
  • the amount of the active ingredient in the solid composition of the present invention is not particularly limited. Rather, it depends on the one hand on the desired dilution effect and on the other hand on the solubility of the active ingredient in the selected excipient.
  • the composition according to the invention may contain from 0.5% to 25% by weight of active ingredient, calculated as the free base, based on the total weight of auxiliary and active substance.

  • any pharmaceutically acceptable excipient capable of producing a homogeneous, molecularly disperse mixture with rasagiline or the like can be selected selected pharmaceutically acceptable salt thereof.
  • the excipient must thus be able to dissolve the active ingredient in the desired concentration.
