How Our Once-Daily Tablet Works

Osmodex® Drug Delivery Technology

RELEXXII (methylphenidate hydrochloride extended-release tablets) utilizes osmotic delivery technology, which allows the medication to be released at a controlled rate throughout the day. With the immediate-release drug layer dissolving within one hour of administration, patients get the medicine they need quickly — and for up to 24 hours — with each daily dose.
