Testing new weight-loss medications alongside birth control

This trial is testing how two new experimental medications—AZD6234 and AZD9550—work together and separately in your body, and whether they interact with birth control pills. Researchers want to understand how these medications are processed by your body and whether they're safe and well-tolerated. You would take the medication in increasing doses while also taking a standard birth control pill, and researchers would monitor how your body handles both.

These are new medications being developed to help with weight management, but before they can be used widely, researchers need to know whether they interact with common medications like birth control pills—and whether women taking both together are safe.
