Abstract
In this article, we validated the use of electric current as an external stimulus to induce an enhancement of drug release from magnetic nanoparticle (MNP) incorporated organogels (magnetogel) under iontophoretic conditions. For this purpose, we adopted a simple, two-step synthesis route to incorporate magnetic (Fe3O4) nanoparticles (MNP) and ciprofloxacin hydrochloride within the network of a soybean oil-based oleogel using stearic acid as gelator. We fabricated a series of MNP incorporated oleogels by varying the wt% of MNPs while keeping a constant weight ratio of soybean oil:stearic acid. The microstructures of the magnetogels were analyzed in MNP concentration-dependent manner by optical microscopy, powder X-ray diffraction, FTIR, mechanical, and electrical studies. Detailed analysis of the electrical properties revealed that the gel sample with a maximum proportion of MNP (S4) allowed the maximum passage of current through it among all the compositions. Under the iontophoretic environment of the active condition, we observed nearly 2.5 fold increase in cumulative drug release in case of sample S4 compared to the corresponding passive condition. These observations suggested that in future, our magnetogel formulation can be further developed as AC field induced ‘remote controlled’ agent for therapeutic application. © 2017
