What's the difference between the half-life of a drug and its duration of action?
Like klonopin for example. I've read that its half-life is 18-50 hours, but that its duration of action is 8-12 hours.
Is that why you have to take klonopin more than once a day even though it has a half-life of 18-50 hours, because even though it lasts in the body for 18-50 hours it is only working therapeutically for the first 8-12 hours?
