The glyceryl distearate is melted. The d-amphetamine sulfate and lactose are mixed together and then added to the melted glyceryl distearate while stirring. After a thorough mixing of the glyceryl distearate, d-amphetamine sulfate and lactose, the mixture is cooled until it congeals to a hard mass, the stirring being continued as long as possible. This mass is ground and sieved through a #35-mesh screen. The sucrose syrup is added to the powder thus obtained and thoroughly mixed with it to mass the powder. The resulting product is granulated through a #10-mesh screen. The granules are dried overnight at 37'C, and sieved through a #14-mesh screen.
