β¦ Synopsis
65". However, a t higher temperatures the samples containing 15 mg. dextroamphetamine sulfate should show a faster rate of browning (Fig. 8). At higher temperatures, sufficient energy was obtained to enable additional intact drug molecules to interact with the lactose. Therefore, the rate of the browning reaction in solid-solid mixtures of dextroamphetamine sulfate and spray-dried lactose is dependent on the concentration of drug in the mixture and the temperature a t which the mixture is stored.
