Abstract

PURPOSE: To provide the titled clathrate by clathrating sodium valporate useful as an antiepileptic using cyclodextrin, thereby suppressing the deliquescence of the compound while keeping the high rate of elution thereof from the clathrate.
CONSTITUTION: A sodium valproate clathrate is prepared by clathrating sodium valproate (2-n-propylvaleric acid sodium salt) with cyclodextrin. The amount of sodium valproate is usually 0.5W10mol per 1mol of cyclodextrin. The clathrating procedure is, e.g. as follows. Cyclodextrin and sodium valproate are mixed with water, and if necessary heated to obtain a suspension or solution. When the cyclodextrin is present in the form of dispersion, the composition is mixed thoroughly with a mixer, etc., optionally filtered, and dried to obtain the objective sodium valproate clathrate.
