> According to RxList riperdal has a half life of about 3 hours in fast metabolizers and 20 hours in slow metabolizers (gene polymorphism). It's active metabolite has a half life of about 20 hours. At steady state most people don't notice they are taking it. I didn't. You must be a fast metabolizer.
fascinating.... how can one tell if one is a fast metabolizer or a slow metabolizer? scientifically, i mean..... is there a blood test ?
