Summary
"This trial aims to study the levels of zavegepant in breast milk after administering a single dose through the nose to healthy breastfeeding women. The goal is to determine if there are any potential risks
Who is the study for?
This trial is for healthy breastfeeding women aged 18 to 55, who are at least two weeks post-partum and not currently pregnant. Participants must be willing to refrain from breastfeeding their infant from the day before receiving the study medication until 48 hours after dosing.
What is being tested?
The study tests how zavegepant, administered as a nasal spray in a single dose of 10mg, transfers into breast milk. Researchers will monitor levels in breast milk and blood over a period of 24 hours to assess any potential risks to infants during breastfeeding.
What are the potential side effects?
While specific side effects are not detailed here, participants may experience reactions typical of nasal sprays such as irritation or discomfort at the site of application. Any other side effects will be monitored during the stay in the clinical research unit.
