Abstract

SAE-CD compositions are provided, along with methods of making and using the same. The SAE-CD compositions comprise a sulfoalkyl ether cyclodextrin having 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.

Claims (27)

4. The SAE-CD composition of claim 1 , wherein the SAE-CD composition comprises an antipsychotic agent.

5. The SAE-CD composition of claim 4 , wherein the antipsychotic agent is selected from the group consisting of clozapine, prochlorperazine, haloperidol, thioridazine, thiothixene, risperidone, trifluoperazine hydrochloride, chlorpromazine, aripiprazole, loxapine, loxitane, olanzapine, quetiapine fumarate, risperidone, and ziprasidone.

6. The SAE-CD composition of claim 1 , wherein the SAE-CD composition comprises a gastrointestinal agent.
