Crystalline cyclodextrin inclusion complexes of ranitidine hydrochloride and process for their preparation |
| abstract |
The present invention relates to cyclodextrin inclusion complexes of ranitidine hydrochloride which exhibit a novel, to date unknown crystalline structure, being significantly different from those of known "Form 1 and 2" and to the preparation of such inclusion complexes. The inclusion complexes are prepared from aqueous common solution or suspensions of ranitidine hydrochloride and cyclodextrin by removal of water. As complexing agents .alpha., .beta.- and gamma-cyclodextrins, their alkylated, hydroxy alkylated derivates or their suitable mixtures are utilized. Finally, the invention concerns pharmaceutical compositions comprising the new complexes. |
