Abstract

Transdermal route is an interesting option in this respect because a transdermal route is convenient and safe, avoid first pass metabolism, predictable and extended duration of activity, minimizing undesirable side effects, utility of short half-life drugs, improving physiological and pharmacological responses, avoiding the fluctuation in drug levels and inter and intra-patient variations. However it has got its own limitations its inability to transport large molecules, inability to overcome the barrier properties of stratum corneum and many more. Formulating the drug in a transfersome is one such approach to solve these problems. Transfersome, is an ultradeformable vesicle, elastic in nature which can squeeze itself through a pore which is many times smaller than its size owing to its elasticity.
