The predominant research within this focal area is directed towards the enhancement of bioavailability for drugs that exhibit poor water solubility, alongside the formulation development of innovative drug delivery systems utilizing platforms such as liposomes, niosomes, nanoparticles, microbeads, nanocochleates, dendrimers, nanocomposites, and nanotubes employing FDA-approved biopolymers. The routes of administration or delivery sites encompass transdermal, sublingual, ocular, oral, and diabetic wound applications, among others. Additionally, an exhaustive characterization of the formulated dosage forms, which includes drug release assessments, kinetic modeling, and in vivo pharmacokinetic investigations, represents further avenues of inquiry within this research focus.
