Background: In the present investigation, tamoxifen-loaded liposomes transdermal patch was formulated using eudragit-RL, hydroxypropyl methyl cellulose K-50, and ethyl cellulose. Materials and Methods: Liposomes were formulated by solvent evaporation method using poly (sebacic acid-co-ricinoleic acid) in varying ratios and evaluated for particle size, drug loading, entrapment efficiency, transmission electron microscopy, differential scanning calorimetry, and X-ray diffraction. Formulated tamoxifen-loaded liposomes were finally incorporated into transdermal patch and evaluated for thickness drug content, moisture content, moisture uptake, folding endurance, tensile strength diffusion coefficient, permeability coefficient, in vitro permeation, and skin irritation. Optimized transdermal patches were tested for its pharmacokinetic and pharmacodynamics parameters Results: Formulated transdermal patches showed improved bioavailability of tamoxifen when compared to its oral route. Conclusion: Tamoxifen-loaded liposomal transdermal patches could serve as a better alternative to existing marketed formulation in terms of bioavailability.
