The objective of this research is to formulate and evaluate Solid Lipid Nanoparticles containing Acyclovir by various phospholipids and surfactants using hot homogenization technique. Totally nine batches of SLN was formulated by hot homogenization technique and evaluates for PS,ZP,PI,Drug content, Entrapment efficiency, Invitro drug release studies and Invitro release kinetics studies. From the data’s, it was concluded that hot homogenization technique method followed by ultrasonication was an optimized technique for the preparation of SLN nanoparticles containing Acyclovir, which lead to better results like high entrapment efficiency, high drug content and SLS was a better choice of surfactant to reduce the particle size and leads to uniform distribution of SLN in its phase. So, SLN will be an alternative drug delivery system for acyclovir to enhance the bioavailability and therapeutic response of drug.
