  • Patent number: 5466682
    Abstract: Compounds of formula (I) ##STR1## in which A is (CH.sub.2).sub.n in which n is 1-10, preferably 3 or 5, and R is the acyl group from a known anti-inflammatory agent, exhibit high anti-inflammatory activity. The mechanism of action is novel because they do not release the anti-inflammatory agent in the body but exhibit an activity superior to the activity of the known anti-inflammatory agent. The compounds are also active in combating bone calcium loss.

  • Patent number: 4786506
    Abstract: A method for the preparation of tablets slowly releasing the active principle, characterized in that (I) during the granulation step a solution in organic solvents of a polymer insoluble in biological juices is sprayed on a mixture containing an active principle, slightly swelling polymers and usual excipients; (II) the granulated obtained in this way is added with a highly hydroswelling colloidal polymer; (III) a solution, in organic solvents, of an entero-soluble polymer, is sprayed on the granulate; (IV) the resulting granulate is submitted to compression; (V) the obtained tablets are hardened by washing with organic solvents; and (VI) they are then optionally coated.
