Summary: This project will evaluate the ability of Mirtazapine (MZP), a pharmacologically unique medication with a growing body of evidence to support its efficacy and safety for the treatment of methamphetamine (MA) use among medication for opioid use disorder (MOUD) patients, to significantly decrease MA use and related health-impairing behaviors. MZP has already successfully been used in the treatment o...

Summary: The purpose of this research is to study the added benefit of treating IBS symptoms with a medication called mirtazapine in treating IBS symptoms when paired with a low-FODMAP diet compared to a low-FODMAP diet alone. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are short-chain carbohydrates that can cause digestive distress in some people. You...
