| titleOfInvention | Alkylated cyclodextrin compositions and methods of making and using the same |
| abstract | The present invention relates to alkylated cyclodextrin compositions and methods of making and using the same. Specifically, the present invention relates to a process for preparing an alkylated cyclodextrin composition comprising an alkylated cyclodextrin, comprising: (a) mixing a cyclodextrin with an alkylating agent to form a reaction environment comprising an alkylated cyclodextrin, one or more undesirable components, and one or more drug-degrading impurities; (b) performing one or more separations to remove the one or more undesirable components from the reaction environment, thereby forming a partially purified solution comprising the alkylated cyclodextrin and the one or more drug-degrading impurities, wherein the one or more separations is ultrafiltration, diafiltration, centrifugation, extraction, solvent precipitation, or dialysis; (c) treating the partially purified solution with phosphate-free activated carbon having a residual conductivity of 10 μ S or less and producing the alkylated cyclodextrin; and (d) measuring the chloride level of the alkylated cyclodextrin composition; wherein the chloride level is 0.07% (w/w) or less. |
