Definitions
- composition containing donepezil hydrochloride, tablet therefrom and process for its preparation
- the present invention relates to a pharmaceutical composition containing crystalline Donepezil hydrochloride of the polymorphic form I and which is suitable for direct compression into tablets, as well as tablets obtained from this composition by direct sizing.
- the present invention relates to tablets in which the donepezil hydrochloride is stable even on storage and does not convert to other polymorphic forms or to the amorphous state.
- Donepezil hydrochloride (+/-) - 2,3-dihydro-5,6-dimethoxy-2 - [[1- (phenylmethyl) -4-piperidinyl] -methyl] -1H-inden-1-one hydrochloride, shows activity as reversible Acetylcholinesterasehemmer and is used in the treatment of various senile dementia, especially in the prevention and alleviation of Alzheimer's disease use.
- the structure of Donepezil hydrochloride is as follows:
- EP 0 296 560 discloses a series of cyclic amine compounds which also include, among others, donepezil hydrochloride for the treatment of age-related dementia.
- Donepezil hydrochloride has a number of properties that make its formulation into a drug more difficult.
- a particular difficulty arises in Donepezilhydrochlorid still in that of the compound in addition to an amorphous five crystalline polymorphic forms I to V are known, which are disclosed in the publications WO 97/046526 and WO 97/046527.
- These references also disclose methods of preparation and characterization of the individual polymorphic forms.
- the polymorphic forms should be stable upon heating and storage, in particular more stable than the amorphous form.
- it is also known that in particular the physical stability of the polymorphic form I is problematic, which can pass into the polymorphic form III when heated or stored.
- EP 1 027 887 discloses pharmaceutical compositions containing amorphous donepezil hydrochloride and a method for stabilizing it by adding a crystallization inhibitor.
- EP 1 378 238 and WO 2004/071486 disclose pharmaceutical compositions containing Donepezil hydrochloride in amorphous state as a therapeutically active agent for the treatment of dementia or Alzheimer's disease.
- Medicines containing the active ingredient donepezil may be compressed, e.g. as tablets.
- the classical process for the production of tablets is a granulation process in which a granulate is produced using a granulating liquid, which is then pressed into tablets.
- a newer method of making tablets is direct compression.
- the individual components of the composition to be pressed are mixed without prior granulation and then pressed directly.
- the Direct compression is an elegant and simple process, but it is difficult to obtain commercially useful tablets which, in addition to sufficient strength, also ensure sufficiently rapid disintegration.
- Many active ingredients can not be processed by direct compression because they are not compressible without granulation step.
- WO 2006/045512 published after the priority date of this application, also describes the problem that donepezil hydrochloride must retain its polymorphic form within a drug formulation.
