Patent number: 6462093Abstract: A process for producing a solid dispersion of a sparingly water-soluble medical substance which comprises subjecting the sparingly water-soluble medical substance, an amorphous state-inducing agent and an amorphous state-stabilizing agent to heat treatment or mechanochemical treatment; and a process for producing a solid dispersion of a sparingly water-soluble medical substance which comprises high-frequency heating the sparingly water-soluble medical substance and an amorphous state-stabilizing agent. These processes make it possible to make sparingly water-soluble medical substance amorphous at a temperature lower than those employed in the conventional methods. The solid dispersions of the armorphous sparingly water-soluble medical substances thus obtained have an improved mucosal or rectal absorption rate, which makes it possible to elevate their bioavailability.Type: GrantFiled: February 6, 1998Date of Patent: October 8, 2002Assignee: Nissan Chemical Industries, Ltd.Inventors: Misao Miyamoto, Toshihisa Oda

Patent number: 6171599Abstract: An amorphous solid dispersion of efonidipine hydrochloride having a high intestinal absorbability can be formed by subjecting a mixture containing efonidipine hydrochloride of the formula (I), hydroxypropylmethylcellulose acetate succinate and optionally a thermostabilizer to a step A of heat treatment at from 85 to 140° C. or mechanochemical treatment at from 0 to 140° C., and then to a step B of dipping treatment into a water-containing solution, impregnation treatment with a water-containing solution or contacting treatment with a water vapor-containing gas; or treating the above-mentioned mixture with a hot steam at from 100 to 140° C. and a high pressure. Further, in the above-mentioned step A, the mixture is subjected to high frequency heating, making it possible to give a solid dispersion of efonidipine hydrochloride having a high intestinal absorbability without using the step B. This process is quite advantageous in the production in that the use of an organic solvent is not required.Type: GrantFiled: September 9, 1998Date of Patent: January 9, 2001Assignees: Nissan Chemical Industries, Ltd., Zeria Pharmaceutical Co., Ltd.Inventors: Misao Miyamoto, Toshihisa Oda, Toyohiko Bunrin, Toshio Okabe, Tetsuyuki Nishiyama
