With the progress in time and advances in science and technology, dosage forms have evolved from traditional systems of simple mixtures, syrups and tablets, to highly sophisticated techniques, which are referred to as novel drug delivery systems. An ideal drug delivery system fulfils the objective of maximizing therapeutic effect while minimizing toxicity. Nanoemulsions are proposed for numerous applications in pharmaceutical sciences as drug delivery systems because of their capacity to solubilize non-polar active compounds. Nanoemulsions have been widely used in development of cosmetic products. One of the versatile applications of nanoemulsions is in the transdermal drug delivery where they act as efficient carriers for bioactives, facilitating ease of administration.
