Intranasal route

The intranasal route is the route of administration of a drug through the nose, including nose drops or other medications. Some drugs have a higher rate of absorption, and are thus more effective in smaller doses, through this route.

The intranasal route may allow certain drugs and other molecules to bypass the blood-brain barrier via diffusion or axonal transport along olfactory and trigeminal nerves.[1]
