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. 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.

Stabilized pharmaceutical composition and method for preparing same

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.

Pharmaceutical composition not containing antioxidant and preparation method therefor

Disclosed are a polymeric drug carrier-containing pharmaceutical composition with enhanced stability in its solution state and a method for stabilizing the same. More particularly, disclosed are a pharmaceutical aqueous solution composition for storage under refrigeration containing a polymeric drug carrier comprising an amphiphilic block copolymer comprised of a hydrophilic block and a hydrophobic block, and a polylactic acid derivative fixed with a di- or tri-valent metal ion at its terminal carboxyl group and having preservation stability for at least 6 months, preferably at least 12 months when stored under refrigeration, and a method for stabilizing the same.
