Transferosomes are also called as transfersomes, ultra deformable vesicles for transdermal applications, consisting of a lipid bilayer with phospholipids An edge activator. Depending upon the lipophilicity of the activesubstance it canbe encapsulated within thecore or amongst the lipid bilayer.Most transfersomescontains phosphatide choline(C18) as it is the most abundant lipid component of the cell membrane. The most common edge activators are surfactants. Application of quality by design(Quds) specifically design of experiments is crucial to understand the interplay among all these factors not only during the preparation add labs scale but also in the scaleup process. Clinical trials of a licensed topical ketoprofen transfersomal gel have shown promising results in the alleviation of symptoms in ortriorities with non-severe skin and subcutaneous tissue disorders.
