What this trial studies

This study evaluates the effects of creatine monohydrate on depression and anxiety in male and female individuals who are dependent on methamphetamine. It aims to determine whether creatine can alleviate depressive symptoms and reduce methamphetamine use while also assessing its safety in this population. Participants must have a current diagnosis of methamphetamine dependence, major depressive disorder, and an anxiety disorder, with specific severity scores on standardized scales. The study will monitor the participants' responses to creatine over a defined treatment period.

Who should consider this trial

Good fit: Ideal candidates are adults with a primary diagnosis of methamphetamine dependence, major depressive disorder, and an anxiety disorder.

Not a fit: Patients with primary substance-related diagnoses other than methamphetamine dependence or those with significant medical or neurological illnesses may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel treatment option for individuals struggling with depression and methamphetamine dependence.

How similar studies have performed: While the use of creatine for depression is an emerging area of interest, this specific application in methamphetamine users is relatively novel and has not been extensively tested in prior studies.
