A member asked:

I was prescribed amphetamine salts er 20mg cap. two a day together by mouth. how much medication is being released at a time?

A doctor has provided 1 answer

About 2mg/hour: these drugs are designed to release a steady amount of their content over the course of 24 hours. There are some forms that release the drug for 18 hours with decreased release through the night hours, but most continuous release amphetamine preparations don't do this.
