Intranasal administration is a method used to deliver medications and vaccines through the nasal passageway. This method of administration is becoming increasingly popular due to its ease of use and enhanced bioavailability, as it avoids first-pass metabolism that occurs with oral delivery. Intranasal administration has the potential to reduce the amount of drug needed, thus improving safety and efficacy of the medication. Furthermore, this administration route could be useful in improving the treatment of neurological and mental illnesses, as drugs can be directly delivered to the brain. In general, intranasal administration has the potential to reduce side effects, improve drug efficacy, and offer an alternative to oral delivery.
