ABSTRACT:
SAE-CD compositions are provided, along with methods of making and using the same. The SAE-CD composition comprises a sulfoalkyl ether cyclodextrin and less than 100 ppm of a phosphate, wherein the SAE-CD composition has an absorption of less than 0.5 A.U. due to a drug-degrading agent, as determined by UV/vis spectrophotometry at a wavelength of 245 nm to 270 nm for an aqueous solution containing 300 mg of the SAE-CD composition per mL of solution in a cell having a 1 cm path length.
