METHOD FOR PRODUCING PHARMACEUTICAL PREPARATION CONTAINING CALCIUM ANTAGONIST/ANGIOTENSIN II RECEPTOR ANTAGONIST

摘要

Provided is a method for producing a pharmaceutical preparation containing a calcium antagonist and an angiotensin II receptor antagonist as active ingredients, said method being characterized by comprising a granulation step of granulating the calcium antagonist and the angiotensin II receptor antagonist together or separately without using water. A pharmaceutical preparation produced by the method can have an elution profile close to the elution profile of a commercially available calcium antagonist preparation and the elution profile of a commercially available angiotensin II receptor antagonist preparation.
