Abstract

Abstract Translated from German Es werden neue nichthygroskopische Calcium- bzw. Magnesiumsalze der 4-Hydroxybuttersäure beschrieben, die sich ausgezeichnet als bzw. in pharmazeutischen Mitteln, insbesondere Schlaf- und Beruhigungsmitteln, verwenden lassen. Da diese Salze nicht hygroskopisch sind, sind sie in fester Form verwendbar und genau dosierbar. Auch Verfahren zur Herstellung dieser Salze sind erläutert. There are described new non-hygroscopic calcium or magnesium salts of 4-hydroxybutyric acid, which can be used excellently as or in pharmaceutical agents, especially sleeping pills and sedatives. Since these salts are not hygroscopic, they can be used in solid form and precisely metered. Processes for the preparation of these salts are also explained.
