Abstract:
A method for producing a drug substance of crystalline pitavastatin calcium excellent in stability, is presented. In the production of a compound (pitavastatin calcium) represented by the formula (1): The water content is adjusted to a level of from 5 to 15%, and the crystal form is controlled to be crystal form A, thereby to obtain a drug substance excellent in stability.

Claim (Index 20):
The method according to  claim 1 , wherein the X-ray powder diffraction pattern of the pitavastatin calcium salt, as measured using CuK\u03b1 radiation, exhibits peaks at diffraction angles (2\u03b8) of 4.96\u00b0, 6.72\u00b0, 9.08\u00b0, 10.40\u00b0, 10.88\u00b0, 13.20\u00b0, 13.60\u00b0, 13.96\u00b0, 18.32\u00b0, 20.68\u00b0, 21.52\u00b0, 23.64\u00b0, 24.12\u00b0, 27.00\u00b0, and 30.16\u00b0.
