Abstract
Preparation of effervescent molded triturate tablets which are rapidly disintegratable and soluble or dispersible in hot or cold aqueous media, said tablets comprising a mixture including two separate, originally pulverulent materials, which are capable of reacting in the presence of water to produce a gas, for instance, sodium bicarbonate and citric acid, the tablets being characterized by the presence of a substantial percentage of voids, generally in the range of 15% to 35%, in the interior of said tablet resulting from the limited interaction of a very minor proportion of said separate, originally pulverulent materials during the production of said molded tablet.
