There are currently no approved pharmacotherapies that can be delivered as scalable and cost-effective treatment options for methamphetamine dependence. Mirtazapine has recently been identified as a promising medication based on two Phase II clinical trials. Mirtazapine is currently an approved generic antidepressant medication that can be delivered as a prescribed take-home medication, making it a potentially scalable and cost-effective treatment option.

To assess the effectiveness, safety, tolerability of mirtazapine for methamphetamine dependence in routine clinical care.

Design and Method

A Phase III double-blind placebo-controlled randomised trial (N = 340). Participants will be assigned to receive either 12 weeks of mirtazapine or equivalent placebo. Trial sites will include Geelong, Wollongong, Brisbane and Perth. Further trial sites to be confirmed.
