A review on intranasal drug delivery system

Abstract

In the present era, the nasal drug delivery system is considered as a viable and favorable way of drug delivery

because it provides patient satisfaction, easy administration; bypass first pass metabolism, excellent access, low dose

requirement, rapid absorption and optimal results. Therefore, many times nasal drug delivery is considered as an

alternative to the parenteral route. Many drug delivery systems have been investigated for the delivery of drugs for

the treatment of CNS disease (ie, Parkinson's disease, Alzheimer's disease) for nasal use of liquid, semiconductor,

and solid formulations because it requires immediate and / or specific drug targeting in the brain. DNA vaccines are

suitable for the delivery of biological products suitable for the delivery of proteins, peptides, hormones, DNA

plasmids.
