Meth Use Research Study

Researchers at the Pacific Treatment and Research Center at UC San Diego are trying to evaluate the efficacy of extended-release naltrexone, an injectable medication, plus bupropion (XR-NTX/BUP-XL) pills compared to a placebo, or a sugar pill/inactive medication, to reduce Methamphetamine use in those with moderate to severe Methamphetamine Use Disorder (MUD).

Conducted in La Jolla, CA

Study Background

Both of these medications (extended-release naltrexone, an injectable medication, plus bupropion (XR-NTX/BUP-XL) pills) are FDA approved and have been used to treat other health conditions. 

During this time, participants will attend study appointments twice a week at our clinic in La Jolla, which we can offer transportation to if needed. They will also use a smartphone app to record themselves taking the study pills every day. After the 12-week treatment phase, participants complete a taper week to taper off the medication, and two follow up visits, for a total of ~19 weeks of participation including the screening visits.
