Die vorliegende Erfindung betrifft neue Arylsulfonamide der Formel
in der
A, B und R₁ bis R₆ wie im Anspruch 1 definiert sind,
deren Enantiomere, deren cis- und trans-Isomere, sofern R₄ und R₅ zusammen eine Kohlenstoff-Kohlenstoff-Bindung darstellen, sowie deren Additionssalze, insbesondere für die pharmazeutische Anwendung deren physiologisch verträgliche Additionssalze mit anorganischen oder organischen Basen, falls R₆ eine Hydroxygruppe darstellt, welche wertvolle pharmakologische Eigenschaften aufweisen, insbesondere antithrombotische Wirkungen und durch Thromboxan vermittelte Wirkungen. Außerdem stellen die neuen Verbindungen gleichzeitig Thromboxanantagonisten (TRA) und Thromboxansynthesehemmer (TSH) dar. Ferner weisen diese auch eine Wirkung auf die PGE₂-Produktion auf.
The invention relates to an otorhinological delivery device comprising at least one pharmaceutically active agent. According to the invention the device comprises a core comprising said at least one pharmaceutically active agent wherein said core is made of an elastomer composition selected from the group consisting of poly(dimethylsiloxane), a siloxane-based elastomer comprising 3,3,3-trifluoropropyl groups attached to the Si-atoms of the siloxane units, a siloxane-based elastomer comprising poly(alkylene oxide) groups and mixtures thereof.

Compositions of tannate salts of phenylephrine and pyrilamine produced by a method that allows for the in-situ conversion and incorporation of the tannate salts in a single dosage form. The conversion process includes dissolving a salts of phenylephrine and pyrilamine in a solvent and mixing with a dispersing agent and tannic acid to generate tannate salts. The tannate salts may be further processed to single dosage forms, such as tablets and suspensions.
