Definitions
- the present invention relates to a composition for parenteral administration comprising Donepezil as an active ingredient and a method for preparing the same, comprising preparing Donepezil, which has been conventionally used for oral or transdermal, as a microparticle including a biodegradable biocompatible polymer and a release regulator.
- a pharmaceutical composition for sustained-release parenteral administration the drug is to be continuously released in vivo for 2 to 12 weeks or more, thereby reducing the frequency of administration to the patient and maintaining an effective concentration in the blood for a long time.
- Donepezil hydrochloride (donepezil hydrochloride) is widely used as a treatment for Alzheimer's disease having an acetylcholine esterase inhibitory effect, most of these anti-dementia drugs are administered orally in tablet form.
- the drug is appropriately selected depending on the disease or the nature of the drug and is administered to the patient in the form of tablets, capsules, syrups, granules, as well as injection, rectal and transdermal administration. Taking it is difficult.
- Pengcheng Zhang et al prepared and evaluated sustained-release microparticles of donepezil (Pengcheng Zhang, Lingli Chen, Wangwen Gu, Zhenghong Xu, Yu Gao, Yaping Li, In in vitro and in vivo evaluation of donepezil-sustained release microparticles for the treatment of Alzheimer's disease, Biomaterials, 28 (2007) 1882-1888). They prepared microspheres containing donepezil using a copolymer of lactide and glycolide, and the content of donepezil in the microspheres was 13.2%, so the drug loading rate was only 66%, and the drug loss was high. In order to do this, there is a problem that the dosage must be very large.
- An object of the present invention is to improve the compliance of the drug done with donepezil, to prepare a donepezil microparticles with a biocompatible polymer and a release control agent, to provide a sustained-release parenteral formulation having a stable drug release for a long time It is done.
- the donepezil microspheres of the present invention may further include a poorly soluble salt of donepezil as a release control agent, and examples of the poorly soluble salt used as the release control agent include xinapoate, nafadisylate and pamoate. .
- the biodegradable biocompatible polymer has an intrinsic viscosity of 0.5 to 1.9 dL / g, for example poly (lactide-co-glycolide), polylactide, polyglycolide, polycapro Lactone, gelatin, hyaluronate, or mixtures thereof, preferably at least one of polyglycolide, polylactide and polyglycolide and polylactide copolymers.
- polyglycolide and polylactide copolymers it is preferred that the molar ratio of lactide to glycolide is 50:50 to 90:10, most preferably 85:15.
- the donepezil microspheres of the present invention may have a size (D50) of 10 to 200 ⁇ m, and the donepezil content of the microspheres is preferably 15 to 50% by weight. If the amount of donepezil in the microspheres is less than 15% by weight, there is a problem of poor drug compliance due to an excessive dose, and when more than 50% by weight, drug release is accelerated, so that a sufficient sustained-release effect is not obtained.
- the donepezil release may last for 2 to 12 weeks or more.
- a step of washing the microspheres with a solvent such as ethanol may be added as necessary, whereby the initial release of donepezil can be suppressed.
- the present invention also provides a pharmaceutical composition for parenteral administration comprising donepezil microspheres comprising donepezil or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier.
- a pharmaceutical composition for parenteral administration is especially an injection.
- Donepezil microspheres according to the present invention has a stable drug release for a long period of time can be maintained in the effective concentration of donepezil in the blood for 2 to 12 weeks or more, when prepared in parenteral administration formulations such as injections and safe Effectiveness can improve patient compliance.
- the prepared microspheres were washed several times with water for injection, followed by wet filtration using a sieve of 25 ⁇ m and 150 ⁇ m size and lyophilized for 64 hours.
- Xinapoic acid as a release regulator was added 1.0 equivalent to the donepezil base, and the remaining production method was carried out in the same manner as in Example 8 to prepare microspheres.
- the prepared microspheres were washed several times with water for injection and subjected to primary wet filtration using a 25 ⁇ m sieve.
- the obtained microspheres were washed with 25% (w / w) ethanol solution for 10 minutes at 20 ° C., and then subjected to secondary wet filtration using sieves of 25 ⁇ m and 150 ⁇ m and lyophilized for 64 hours.
- FIG. 1 is a photograph showing a SEM analysis result of measuring the form of donepezil microspheres according to each embodiment.
- 1A is Example 1
- FIG. 1B is Example 1-1
- FIGS. 1C-1H are Examples 2-7
- FIG. 1I is Example 2-1
- FIGS. 1J and 1K are Examples 8 and 8-, respectively.
- FIG. 1L and 1M are SEM photographs of the microspheres prepared in Example 9 and Example 9-1, respectively.
- microspheres About 100 mg of microspheres were put in a GC vial and dissolved in 10 mL of internal standard solution, and residual solvent was measured in the microspheres using GC.
- the column used was filled with G25 series, the inner diameter was 25m ⁇ 0.32mm, the film thickness 0.5 ⁇ m, 1 ⁇ l injection, the temperature was measured using a flame ionization detector at 250 °C.
- Diluent preparation 500 mg of mannitol, 50 mg of sodium carboxymethylcellulose, and 10 mg of polysorbate 80 were dissolved in purified water for injection to make 10 mL, and sodium hydroxide was added to prepare pH 7.0.
