Abstract: Intranasal administration has proven to be a viable alternative for local and systemic
delivery of varied therapeutic agents. This route has been potentially researched for delivering polar
compounds, vaccines, hormones, peptides, proteins, etc. Being non-invasive and painless with
a fast onset of action (both local and systemic), intranasal has become an ideal route for medication
to children. This route is specifically employed for the delivery of drugs that are unstable in
GIT, which gets significantly degraded or metabolized by the first-pass effect. The nasal route's
high absorption and permeability profile has led to its exploration as a substitute for parenteral delivery.
This paper reviews the feasibility and potentials of intranasal administration, discussing its
benefits, drawbacks, market analysis, factors affecting nasal drug delivery system, conventional
and novel strategies (polymeric and nano-carrier-based delivery systems) to improve nasal absorption
and its clinical management of varied systemic and topical disorders viz. neurodegenerative,
pulmonary, microbial, neoplastic, etc.
