Definitions
- the present invention relates to oral dosage film preparations containing the donepezil freebase as an active ingredient and a process for preparing the same.
- Donepezil is a representative Alzheimer's agent among several Alzheimer's agents currently on the market, and is currently available in tablet formulations containing the form of Donepezil hydrochloride.
- film formulations are desirable given the circumstances in which such Alzheimer's therapeutics are used, portability, and the like.
- donepezil hydrochloride has a distinctive irritating and arid taste, making it difficult to prepare into oral dosage film formulations.
- the problem to be solved by the present invention is to provide a film and a method for producing the same, including donepezil, does not have a pungent taste, has a thickness and size suitable for taking, excellent handleability and physical properties.
- the present invention provides a method for producing a film containing a tasteless donepezil free base as an active ingredient and a film produced according to such a method. More specifically, the present invention provides a method for producing a donepezil free base-containing film, and a film prepared according to the method, characterized in that the polymer solution in which the donepezil free base is dispersed (without substantially dissolving). to provide.
- the present invention is not suitable for oral administration film formulations because of the use of commercially available Donepezil hydrochloride in the oral cavity, which is uniquely suited for film formulations. Based on.
- donepezil hydrochloride is dissolved in water is not suitable for preparing the dispersion (suspension) as in the present invention, while the donepezil free base is almost insoluble in water can achieve the purpose of the present invention.
- the film when the film is prepared from a polymer solution suspended (dispersed) without substantially dissolving a donepezil free base, the film contains a desired amount of donepezil, but has a suitable thickness and size for taking as well as the desired physical properties. Based on the finding that a film can be obtained.
- the film may be referred to as a strip, an orally dissolving film, an orally disintegrating film, or the like, and is dissolved in the oral cavity of the tongue, oral mucosa, and sublingual.
- Film formulations according to the invention have the advantage that they can be taken without water.
- "suspended substantially without dissolving" means that 15% by weight or less of the total donepezil free base is dissolved, preferably 10% by weight or less, more preferably 7% by weight or less, Even more preferably 4% by weight or less, most preferably 2% by weight or less.
- the content of donepezil free base relative to the total weight of the dried film may be 5 to 30% by weight.
- the donepezil free base when included in less than 5% by weight, it is uneconomical and likely to cause process problems, and when included in more than 30% by weight, the strength of the film may be weakened.
- the donepezyl free base is substantially insoluble and does not interact with the film-forming polymer. Therefore, even if a high content of donepezil free base is included, it is assumed that the formed film exhibits desirable physical properties.
- the present invention is not limited to this theory.
- a dispersion stabilizer is required to uniformly disperse the donepezil free base in the film without substantially dissolving it.
- a vinyl polymer-based compound may be used as a dispersion stabilizer for dispersing donepezil free base, and the addition of the vinyl polymer-based compound may maximize dispersion stability in the film without dissolving the donepezil free base. It is based on the finding that there is an effective effect and the particle reaggregation phenomenon can be suppressed after the film liquid is produced.
- the vinyl polymer compound used as the dispersion stabilizer includes, for example, polyvinyl alcohol (PVA), polyethylene glycol / polyvinyl alcohol copolymer, polyvinylpyrrolidone, polyvinylacetate, polyvinylpyrrolidone / Physical mixtures of polyvinylacetate, vinylpyrrolidone / vinylacetate copolymers, or polycaprolactam-polyvinylacetate-polyethyleneglycol graft copolymers, and the like.

- the dispersion stabilizer may be included 0.1 to 50% by weight, most preferably 5 to 20% by weight based on the total weight of the dried film.
- the dispersion stabilizer when included in less than 0.1% by weight, re-aggregation of donepezil particles occurs in the produced film, and uniform dispersion of donepezil is difficult.
- the fragrance may appear and cause process problems.
- the vinyl polymer-based compound is included for dispersion stabilization of donepezil, and polymer chains beyond the simple suspension of other additives, especially the donepezil free base, in the polymer solution by using the vinyl polymer-based compound as the dispersion stabilizer. It is possible to more stably disperse the donepezil free base in between, or to reduce the amount of the additive used to reduce the aggregation between the donepezil particles. For example, the total amount of dispersion stabilizer, plasticizer, and surfactant can be reduced. In particular, it is possible to reduce the amount of nonionic surfactants (such as polysorbate 80, etc.) and anionic surfactants (such as sodium lauryl sulfate, etc.). It can solve the problem of peculiar pungent taste.
- nonionic surfactants such as polysorbate 80, etc.
- anionic surfactants such as sodium lauryl sulfate, etc.
- Dispersion stabilizers, plasticizers, and surfactants that may be included in the entire film include, in addition to vinyl polymer-based compounds, such as docuate sodium, sodium lauryl sulfate, polysorbate, polyethylene glycol, propylene glycol, polyoxyethylene alkyl ethers. ), Polyoxyethylene caster oil, polyoxyethylene stearates, triethyl citrate, glycerin or mixtures thereof, but do not impair the object of the present invention. Any compound known in the art may be used and is not limited to the examples described above.
- the content of the vinyl polymer-based compound based on the total weight of the dispersion stabilizer, plasticizer, and surfactant included in the dried whole film may be 0.2 to 100% by weight, most preferably 5 to 50% by weight.
- the amount of solvent used in film production is preferably 0.7 to 4 parts by weight relative to 1 part by weight of the film constituent material remaining after drying. It is more preferable that it is 1.3-3.3 weight part.
- the present invention is prepared by drying a solution in which the polymer is dissolved, the donepezil free base is dispersed in a solution using water of at least 90% by weight of the solvent, the content of the polymer to the total weight of the dried film
