Preparation and Characterization of Micelles

Nanoformulations in the past few decades have gained tremendous attention owing to their affirmative applications in increasing the bioavailability of poorly soluble drugs. Micelles in particular are favored due to their varied advantages which include thermodynamic stability, simple formulating steps, Newtonian flow, and enhanced biological barrier penetration. Owing to these advantages micellar nanosystems find extensive applications in oral, transdermal, and parenteral administration, and are now being explored for ocular and other noninvasive novel pathways of drug delivery such as nose to brain. In this chapter, we have discussed the protocol for the preparation of sumatriptan loaded micelles for the therapy of migraine. The inner core of these micelles comprises hydrophobic region of diblock polymer which holds the drug, while the hydrophilic region of the same provides conformational stability in the aqueous environment.
