Present study deals with the formulation and characterization of testosterone bearing solid lipid nanoparticles for transdermal drug delivery. Solid lipid nanoparticles of testosterone were prepared by ether injection method. Solid lipid nanoparticles were prepared by testosterone, glyceryl mono stearate, brij 35, propylene glycol and double distilled water. Four different formulations i.e. F1 to F4 were prepared in different quantity of brij 35. All the solid lipid nanoparticles formulations were characterized on the basis of electron microscopy, particle size by zeta sizer, polydispersity index, encapsulation efficiency, viscosity and in vitro drug release study. Average size and polydispersity index of developed formulation F3 found to have 298 nm and 0.328 respectively, determined by zeta sizer. Encapsulation efficiency of formulation F3 was found to have 54.16%. Viscosity of formulation was also enough to handle for transdermal application. All the formulations followed zero order release profile. |
