Process for the production of insertable pharmaceutical compositions and novel products thus obtained. These compositions comprise a mixture of an aqueous solution of carboxyvinyl polymer with a basic water soluble compound and a pharmaceutical ingredient, the mixture being a gel having a pH value of 4 to 10 and a viscosity of 5,000 to 100,000. centipoise at 20 degrees C. The present invention is particularly useful for providing compositions which are applied to tissues of the rectum, vagina or urethra, the pharmaceutical ingredient being absorbed into the blood stream of the human body. |
