This study is looking at how the drug cimetidine (used to treat heartburn and ulcers) gets into breast milk. Researchers want to understand how certain proteins (OCT1 and BCRP) in the breast gland affect this process. You might be able to join if you are a healthy woman between 18 and 50 years old who has recently given birth and is breastfeeding. The study will measure how much cimetidine is in your breast milk at different times after you take it. This will help us understand how drugs are passed to infants through breast milk. The study plans to enroll 50 participants, but its current status is unclear.
