Large surface area presented by pulmonary system offer better target using anti-cancer drug deposition for localized effect in the lungs. Protransfersomes are dry powder formulations, whereas transfersomes are liquid dispersions containing vesicles generated from protransfersomes upon hydration. Protransfersome powder formulations (F1 – F27) (referred as Micro formulations based on transfersomes vesicles size post hydration) were prepared by employing phospholipid (Soya phosphatidylcholine (SPC)), three different carbohydrate carriers (Lactose monohydrate, LMH; Microcrystalline cellulose, MCC; and Starch), three surfactants (i.e. Span 80, Span 20 and Tween 80) in three different lipid phase to carrier ratios (i.e. 1:05, 1:15 and 1:25 w/w), with the incorporation of PTX as a model drug. Hydrophobic chain of SPC may enhance PTX solubility as well as its accommodation to improve entrapment and delivery via transfersome vesicles to the target site. Out of the 27 Micro protransfersome formulations, PTX-loaded LMH powder formulations F3, F6 and F9 (i.e. 1:25 w/w lipid phase to carrier ratio) exhibited an excellent powder flowabil...
