After 24 hours, the eggs were opened and injected with sterile drugs, and then reclosed using plastic tape. After a period of 72 hours, the eggs were opened and assessed using the Hamburger–Hamilton chickembryology classification method. TUNEL staining was used to identify apoptosis, and hematoxylin–eosin staining was used toinvestigate neural tube closure.RESULTS: Treatment with rizatriptan significantly slowed down neural tube development. The supra-therapeutic group showedneural tube closure defects.CONCLUSION: Rizatriptan had a negative effect on neural tube closure. Further research is needed to identify a safe and effectivedrug for treating migraines during pregnancy.engAraştırma Makalesi10.5137/1019-5149.JTN.23431-18.1
