Do alcohol treatment medications work differently for men and women?

What is it about?

This study asks whether medications for alcohol use disorder work equally well for men and women. Researchers pooled results from 28 studies covering over 25,000 people to compare how men and women responded to drug treatments for drinking. They found modest overall benefits from these medications, and some hints that naltrexone may work better for men while baclofen may work better for women, though the evidence wasn't strong enough to be certain.

Why is it important?

Most alcohol use disorder trials weren't designed to detect sex differences, and only a quarter of participants across the studies were women. This gap means treatment decisions rest on evidence that may not apply equally to everyone. By pooling data across 25,041 participants, this review shows current trials are underpowered to answer the sex-difference question and calls for adequately powered, sex-stratified trials. That shift could make alcohol treatment more effective and equitable for women and men alike. It's also important to explore what this means for those who are outside the gender binary too, as often they are missed from research.
