First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how a new drug called KarXT interacts with three common mood stabilizers (lithium, valproic acid, and lamotrigine) in 133 healthy adults. Researchers measured drug levels in the blood and checked for side effects. The goal was to understand if these drugs affect each other's safety and processing in the body.
