The present invention relates to a blood pressure regulator containing 1α-hydroxyvitamin D 3 . In recent years, as a result of a series of studies by De Luca et al. and Kodiek et al., vitamin D3
The active substance in the body is 1α,25-dihydroxyvitamin D 3 (hereinafter abbreviated as 1α,25-(OH) 2 -D 3 ), and the presence of a hydroxyl group at the 1α position is essential for the expression of its biological activity. It was revealed that. Hereafter analogs of this active form of 1α,25-(OH) 2 -D 3 ,
For example, 1α-hydroxyvitamin D 3 (hereinafter 1α-
(OH)-D 3 ), 1α,24-dihydroxyvitamin D 3 (hereinafter abbreviated as 1α,24-(OH) 2 -D 3 ), and many other 1α-hydroxyvitamin D 3 types. Along with 1α,25−(OH) 2 −D 3 , its vitamin D-like biological activity has attracted attention, and 1α−
(OH)-D 3 is chronic renal failure, hypoparathyroidism,
It is indicated for improving various symptoms associated with abnormal vitamin D metabolism (hypocalcemia, tetany, bone pain, bone lesions, etc.) in vitamin D-resistant rickets and osteomalacia. As a result of continued intensive research, the inventors found that
The present invention was completed based on the discovery that 1α-hydroxyvitamin D type 3 has a blood pressure regulating effect. That is, the present invention relates to a blood pressure regulating agent of the 1α-hydroxyvitamin D 3 class. What is the 1α - hydroxyvitamin D type 3 used in the present invention? −(OH) 2 −D 3 , 1α, 24S, 25−(OH) 3 −D 3 , 1α, 24R, 25−(OH) 3 −D 3 , 1α, 25S, 26−(OH) 3 −D 3 , 1α, 25R, 26−(OH) 3 −D 3 , 1α, 25−(OH) 2 −23−OXO−D 3 , 1α, 25−(OH) 2 −24−OXO−D 3 , 1α, 25S ,26−(OH) 3 −23−OXO−D 3 , 1α,25R,26−(OH) 3 −23−OXO−D 3 , 1α,25S−(OH) 2 −D 3 −26,23S−lactone , 1α,25R−(OH) 2 −D 3 −26,23S−lactone, 1α−(OH)−24,25,26,27−tetraucr−23−
Includes COOH- C3 , etc. These substances are, for example, US Patent 3697559,

Biophys., 204 , 387 (1981), HFDe Luca, Vitamin D - [The New Trend], Kodansha, Scientific (1982), etc. In the present invention, any of the optical isomers may be used, or two or more types may be used as a mixture. The blood pressure regulating agent of the present invention contains the above substance as an active ingredient and is used in various formulations shown below. The blood pressure regulator of the present invention is administered orally or parenterally. Examples of dosage forms that can be used include compressed tablets, coated tablets, hard or soft elastic gelatin capsules, ethyl alcohol solutions, oily or aqueous solutions or suspensions. As solvents for oily solutions, vegetable oils such as coconut oil, corn oil, cottonseed oil, coconut oil, peanut oil, fish liver oil, oily esters such as polysorbate 80, etc. can be used. For rectal administration, the pharmaceutical composition may include a suppository base, such as cocoa butter or its triglycerides. The substance may be present in unit dosage form between 2 x 10 -5 and 1 x 10
%, preferably 2×10 −4 to 1%. Further, the dosage can be 0.1 to 10 4 μg/day/person, preferably 0.5 to 10 3 μg/day/person. Then, so that the above quantitative relationship is maintained,
The drug is prepared so that it can be administered 1 to 3 times a day. Hereinafter, the present invention will be explained in detail with reference to Examples. Example 1 Blood pressure regulating effect This substance dissolved in triglyceride ester of intermediate fatty acids (hereinafter referred to as MCT) was used in spontaneously hypertensive rats (SHR), which most closely resembles essential hypertension in humans and is an excellent model animal for hypertension. was orally administered at a concentration of 1 μg/Kg. Also,
MCT alone was orally administered to the control group. Before administration,
At 6 and 12 hours after administration, tail artery pressure was measured non-invasively as blood pressure using a blood pressure measuring device (manufactured by Ueda Seisakusho, model USM-105R). The results are shown in Table 1 below. The results are shown as the average value of 5 rats aged 20 to 25 weeks in each group.
