Disclosed are an anionic drug-containing polymeric micelle particle comprising: an anionic drug as an active ingredient; a cationic lipid; and an amphiphilic block copolymer, wherein the anionic drug forms a complex with the cationic lipid, and the complex is entrapped in the micelle structure of the amphiphilic block copolymer, and a method for preparing the same. The particle may increase stability of the anionic drug in blood or in a body fluid, and it may enable intracellular delivery to improve efficacy of anionic drugs.


Disclosed are microparticles containing physiologically active peptides, a method for preparing the same, and a pharmaceutical composition comprising the same.


Patent
Samyang Biopharmaceuticals Corporation | Date: 2016-11-09

Provided are a composition containing an unstable drug against oxidation like pemetrexed with improved stability and a preparation method thereof, by removing oxygen during the preparation without use of an antioxidant. The method is readily applicable for manufacturing by freezing and degassing in a sealed chamber, and can provide formulations with significantly increased stability for the unstable drug against oxidation.


The present invention relates to a method for preparing an improved intermediate for producing high-purity pemetrexed and a method for producing high-purity pemetrexed using the intermediate, and more specifically, to a novel method for preparing pemetrexed diethyl ester, which is an intermediate for producing pemetrexed, or a salt thereof with high purity, and to a method for producing pemetrexed disodium salt with high purity using the intermediate.
