  • Calcium channel antagonist possessing an inhibitory action against secretion of parathyroid hormones and a use thereof
    Patent number: 6475532
    Abstract: Disclosed is a calcium channel antagonist effective as a single substance for attaining dual purposes of inhibiting secretion of parathyroid hormones and of promoting absorption and utilization of calcium in human body as well as a process for preparing the calcium channel antagonist. According to the present invention the calcium channel antagonist is prepared by baking a calciferous material of plant origin at a temperature of 500-1000° C. under reduce pressure or vacuum and extracting the baked material with and acidic substance. The calcium channel antagonist may be incorporated with a conventional calcium preparations to enhance bioavailability of calcium. Further, the calcium channel antagonist of the present invention may be processed to calcium preparations in the form of porous granules.
