PHYSICALLY STABLE AND X-RAY AMORPHOUS FORM OF HYDROCHLORIDE RANITIDINE HAVING AN INCREASED ANTI-ULCER ACTIVITY AND METHOD FOR PRODUCING THE SAME

摘要

The present invention relates to a new and formerly known form of hydrochloride ranitidine having H2-blocking properties. This form is X-ray amorphous, substantially differs from the formerly known crystalline modifications due to its characteristics, and also exhibits an enhanced anti-ulcer effect. This X-ray amorphous form is physically stable and can be used in medicine. This invention also relates to a method for producing this X-ray amorphous form from formerly known crystalline modifications.
