Abstract: Objective To prepare the acyclovir palmitate ( ACVP) submicron emulsion. Methods The ACVP O/W submicron emulsion was prepared by high-pressure homogenization method.In order to evaluate the stability of the ACVP submicron emulsion，the physical properties such as emulsion droplet size distribution, Zeta potential, pH and content were determined. Results The mean droplet size was (206±26) nm, Zeta potential was –35.8 mV, pH was 7.78, and the content was eligible. Conclusion The ACVP submicron emulsion was stable with good results.
