Transfersome is a proprietary drug delivery technology, an artificial vesicle designed to exhibit the characteristics of a cell vesicle suitable for controlled and potentially targeted drug delivery. Some evidence has shown efficacy for its use for drug delivery without causing skin irritation, potentially being used to treat skin cancer. Transfersome is made by the German company IDEA AG. Transferosomes have recently been introduced, which are capable of transdermal delivery of low as well as high molecular weight drugs. This offers several potential advantages over conventional routes like avoidance of first pass metabolism, predictable and extended duration of activity, minimizing undesirable side effects, utility of short half-life drugs, improving physiological and pharmacological response and have been applied to increases the efficiency of the material transfer across the intact skin, by the use of penetration enhancers, iontophoresis, sonophoresis and use of colloidal carriers such as lipid vesicles (liposomes & proliposomes) and non-ionic surfactant vesicles (niosomes & proniosomes).
