摘要:
A process and equipment assembly for reacting a substituent precursor with a cyclodextrin starting material to provide a raw product comprising a cyclodextrin derivative and 1% or less of an initial amount of the substituent precursor is provided. The process of the present invention provides cyclodextrin derivatives in substantially shorter time and with fewer side products than previous processes that utilize substantially the same starting materials.
摘要:
The invention relates to a method of improving the stability of clopidogrel in a composition comprising clopidogrel, the method comprising adding a sulfoalkyl ether cyclodextrin (SAE-CD) of Formula 1:
wherein: n is 4, 5, or 6; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , and R 9 are each, independently, -O- or a -O-(C 2 -C 6 alkylene)-SO 3 - group, wherein at least one of R 1 to R 9 is independently a -O-(C 2 -C 6 alkylene)-SO 3 - group; and S 1 , S 2 , S 3 , S 4 , S 5 , S 6 , S 7 , S 8 , and S 9 are each, independently, a pharmaceutically acceptable cation, to the composition, wherein the molar ratio of the SAE-CD to the clopidogrel is at least 6:1, when the pH of the formulation is 3.5 or greater.
