intranasal delivery
Intranasal delivery is a non-invasive method for administering medication directly into the nasal cavity, allowing for rapid systemic absorption or direct transport to the brain. It bypasses the blood-brain barrier (BBB) and hepatic first-pass metabolism, making it ideal for treating CNS disorders (e.g., Alzheimer’s, migraines), pain management, and emergency situations (e.g., seizures, overdose).
