QUILLIVANT XR® – SMOOTH RELEASE THROUGHOUT
THE DAY

Quillivant XR® (methylphenidate hydrochloride): After an initial rapid rise in blood levels, a gradual tapering off throughout the day with no additional peaks

Pharmacokinetics (PK) describes the way in which a person’s body absorbs, distributes, metabolizes, and excretes a medication. The PK properties of Quillivant XR were studied in healthy adults who were given 60 mg of Quillivant XR compared to an immediate-release (IR) liquid methylphenidate solution, in two equal doses of 30 mg each, 6 hours apart. Blood samples were collected before and then at several time points after taking the drug. The amount of methylphenidate in each sample was then measured in a laboratory.

As shown in the chart below, blood levels of methylphenidate increased rapidly after taking Quillivant XR, reaching a peak around 5 hours. Levels then gradually decreased from 5 hours through 24 hours.

Blood levels of methylphenidate in people who took the IR solution increased and decreased quickly. After a second dose of the IR solution, the blood levels again showed a quick rise and a quick drop off.

Unlike IR methylphenidate solutions, Quillivant XR provides steady levels throughout the day in a once-daily dose with no additional peaks.

  • The use of LiquiXR ® technology gives Quillivant XR (methylphenidate HCl) approximately 20% immediate-release and 80% extended-release methylphenidate

LiquiXR ® technology is an ion exchange polymer chemistry that enables continuous release of the medication throughout the day.
