the invention belongs to the
drug technical field, disclosing a sulphur butyl
ether-beta-
cyclodextrin(SBE-beta-CD)
clathrate compound of cinnarizine, a preparation thereof and a preparation method thereof. The
water soluble beta-
cyclodextrin derivative SBE-beta-CD is used as a
coating material to prepare the cinnarizine
clathrate compound. The process comprises the following steps that: the BE-beta-CD is dissolved in proper amount of water, the pH value is adjusted by
hydrochloric acid, the cinnarizine is added in the
mixed solution and stirred for ultrasonic
dissolution, the mixed solutionobtained is added with
sodium hydroxide to adjust the pH value, a clathrate solution is obtained, and the clathrate solution is subject to
freeze drying or
spray drying to form
clathrate compound powder; the clathrate compound solution obtained is subject to degerming, pyrogen removal, sterile filling and
freeze drying to obtain freeze-
dry powder needles for injection; the clathrate compound solution is subject to
spray drying, and the obtained
powder is directly subject to sterile subpackaging or mixed with proper amount of auxiliary materials for sterile subpackaging; and the clathrate compound
powder can be mixed with other auxiliary materials to prepare tablets, capsules and particles, etc. according to requirements.
