Sponsor

Christopher Gale

Enrollment

10 participants

Start Date

Oct 5, 2020

Study Type

Interventional

Conditions

Methamphetamine Use Disorder

Summary

This is an open label, pragmatic, dose finding study looking primarily at the safety of Methylphenidate OROS at doses used above those for treating ADHD. We would expect participants to abstain from using methamphetamine or methylphenidate for 24 hours prior to testing. Patients who have a DSM 5 diagnosis of Methamphetamine Use Disorder, if consented, will have serial doses of 56, 108, 164, and 216 mg of Methylphenidate sustained release (OROS methylphenidate) with an increase in the dose used every day followed by five hours of post dose monitoring each day. For the purposes of this pilot study, we will, pragmatically, recruit 10 participants.

Interventions

Patients who have a DSM 5 diagnosis of Methamphetamine Use Disorder, if consented, will have serial doses of 56, 108, 164, and 216 mg of Methylphenidate sustained release (OROS methylphenidate) tablet with an increase in the dose used every day followed by five hours of post dose monitoring each day. The dose will be administered as one dose daily after review of side effects, Blood Pressure had Heart rate, and a rapid urine drug screen. The dose will increase daily for four consecutive days.
