Abstract
Localized drug delivery to the breast tissues is an area of interest as a potential route to ensure site-specific drug delivery. Transpapillary delivery via the mammary papilla has advantages as most breast tumors arise from the milk ducts. The present study explored the plausibility of transpapillary delivery of a phytochemical, resveratrol (RVT), for breast cancer treatment. RVT was encapsulated within the transfersomes (RVT-TRF) to enable a sustained release of the drug using the biomaterial soya phosphatidylcholine (SPC). Iontophoresis was applied to further accelerate the penetration of the RVT-TRF across the mammary papilla to the breast tissue. The RVT-TRF development was optimized by the Design of Experiments (DoE) approach. The in vitro transpapillary iontophoresis study on porcine mammary papilla showed an enhanced penetration of RVT-TRF when compared to passive diffusion. The transpapillary delivery was further confirmed from the in vitro fluorescent microscopy study using FITC conjugated RVT-TRF. The optimized RVT-TRF delivered via transpapillary route showed a higher Cmax and AUC when compared to pure RVT given orally. A significant reduction in the tumor volume and the serum biomarker CA 15-3, when evaluated in a chemically induced breast cancer rat model, provided evidence of the effectiveness of the developed formulation when delivered locally via transpapillary route compared to the oral route. Thus the developed RVT-TRF administered via transpapillary iontophoresis technique is a promising strategy enabling a localized delivery for effective breast cancer therapy.

Abstract
The present study was designed for the development of a stable sustained release liposomal drug delivery system for tamoxifen citrate (TC) using soya phosphatidylcholine (SPC), cholesterol (CH) and span 20 as main ingredients. Liposomes were prepared by formation of thin lipid film followed by hydration. The mean vesicle diameter was found to be 203.5 ± 19.5 nm with 21% of the liposomal population having average diameter below 76.72 ± 6.7 nm. There was a good vesicular distribution with the polydispersity index of 0.442 ± 0.03. The maximum loading of drug was determined to be 53.60% of the initial amount that is 34.58 μg of drug per mg of lipid. Amongst the different storage conditions, liposomes stored at 2–8°C were found to be most stable and only 4% of the drug was lost over the storage period of 5 weeks. In vitro release studies of liposomes showed that 50% of drug was released within 3 hours (h) whereas 95% drug was released in 30 h. This indicates the usefulness of the liposomal delivery system for sustaining the in vitro release of tamoxifen citrate.
