Intranasal Delivery Of Insulin By Nanoemulsion System, Darshana Mahendrakumar Shah

Theses and Dissertations

The main objective of this research was to develop an o/w nanoemulsion dosage form of insulin for intranasal delivery where insulin is loaded into the oil phase of the nanoemulsion for enhanced absorption. When loaded into the lipid droplets (oil phase), insulin can be protected from enzymatic degradation, can permeate through the mucus gel barrier in a comparatively efficient manner and can be absorbed through transcellular permeation along with paracellular route. To incorporate lipophilicity to insulin molecule, several complexes of insulin with various amphiphiles were developed to load it into the oil phase. The cytotoxicity of these amphiphiles and the …
