A Study to Learn How the Study Medicine Called Zavegepant is Taken Up Into Blood and Breast Milk of Healthy Breast-Feeding Women

The purpose of the study is to look at the amount of zavegepant that is present in breast milk after single dose of zavegepant is sprayed through the nose in healthy breast-feeding women. This would allow to see if there are any possible risk to infants from medicines during breast-feeding. The study is seeking for about 12 healthy breast-feeding females who are: * 18 to 55 years of age. * actively breast-feeding or producing breast milk. * at least 2 weeks post-partum and not pregnant at present. Participants will not be allowed to breast-feed their infant from the evening of the day before to the first dose till 48 hours (2 days) after the dose. Eligible participants will check into the clinical research unit (CRU) on Day -1. Participants will receive the zavegepant dose sprayed into the nose at the CRU on Day 1. The participants will stay at the CRU until the morning of Day 2. There will be collections of breast milk and plasma over 24 hours. Participants will be sent from the CRU on Day 2 and may begin to breastfeed their infant 48 hours (2 days) after the dose. A safety follow-up call will be done at about 28 to 35 days from the day the first dose of study medicine was given.
