Abstract
Abstract AN ANTIFOAMING PRODUCT, WHICH RETAINS ITS ANTIFOAMING ACTIVITY IN THE PRESENCE OF ANTI-ACIDS AND OTHER DRUGS, IS PREPARED BY SUSPENDING UP TO 20% BY WEIGHT OF AN ANTIFOAMING ORGANO-POLYSILOXANE, SUCH AS SIMETHICONE, IN MOLTEN SORBITOL, COOLING THE SUSPENSION TO HARDEN IT AND THEREAFTER REDUCING IT TO A POWDER OF A PARTICLE SIZE LARGER THAN ABOUT 115 MESH. THE NEW ANTIFOAMING COMPOSITIONS MAY BE USED IN THERAPEUTICALLY ACTIVE AMOUNTS IN THE PREPARATION OF COMPOSITIONS FOR THE RELIEF OF GASTROINTESTINAL DISTRESS CAUSED BY FLATLENCY.
