Abrégé
The present invention relates to a composition for parenteral administration, containing donepezil as an active ingredient, and a preparation method therefor. Donepezil, which has been conventionally used for oral or transdermal administration, is prepared as microparticles comprising a biodegradable and biocompatible polymer and a release controller so as to be provided as a pharmaceutical composition for sustained release parenteral administration, thereby enabling in vivo sustained release continuously for 2-12 weeks or more. Therefore, it is possible to reduce the frequency of administration to a patient and maintain an effective concentration in the blood for a long time.

Provided is a process for preparing Voriconazole represented by Chemical Formula 1. More particularly, the process for preparing Voriconazole of Chemical Formula 1 includes: carrying out the Reformatsky-type coupling reaction between a ketone derivative of Chemical Formula 4 and a pyrimidine derivative of Chemical Formula 5 to obtain a compound of Chemical Formula 3; reacting the substituents halo and oxysulfonyl with a hydrogen donor to obtain racemic Voriconazole of Chemical Formula 2; and carrying out optical isolation of the racemic Voriconazole by adding an adequate optically active acid thereto to obtain Voriconazole having high optical purity with high cost-efficiency and high yield.

Abrégé
The present invention relates to a method for manufacturing a sustained release microsphere which is able to continuously control the release of a drug. More specifically, the present invention relates to a method for manufacturing a sustained release microsphere through a solvent flow evaporation method using a cosolvent when manufacturing a microsphere in which a drug is sealed in a carrier comprising biodegradable polymers. Thus, early excessive release of a physiologically active substance is suppressed so the physiologically active substance can be continuously and uniformly released in the body.
