Intranasal Spray

Meaning

An Intranasal Spray is a specialized pharmaceutical drug delivery system where a liquid formulation of a therapeutic agent, such as a peptide or hormone, is finely atomized and administered directly into the nasal cavity. This route of administration is clinically utilized to achieve rapid systemic effects or highly localized action, providing a convenient, non-invasive alternative to traditional injection methods. The nasal mucosa’s extensive vascularity allows for quick absorption into the systemic circulation, successfully bypassing the metabolic processes of hepatic first-pass metabolism.
