Background: Phenylbutazone is a class of non-steroidal anti-inflammatory drugs (NSAIDs) used in the treatment of rheumatoid arthritis. Phenylbutazone is used by the transdermal route to reduce the irritating effect on the gastrointestinal tract. Purpose: This study aims to obtain phenylbutazone suspensions with optimal levels in the ethosome vesicular carrier. Methods: Preparation was carried out by the hot method (40C) and cold method (30C) as well as variations in the concentration of phosphatidylcholine (2% and 3%) and ethanol (30%, 35%, and 40%). Characterization of vesicles, namely the shape and size of vesicles using optical microscopy and entrapment efficiency using the spectrophotometer method with λ maks 266.6 nm. Optimization of phenylbutazone levels was carried out at a concentration of 0.1%; 0.15%; 0.2%; and 0.25%. The optimum formula was obtained at a concentration of phosphatidylcholine 3% and ethanol 35% prepared by the hot method. Results:. The form of a Small Unilamellar Vesicle (SUV), a size of 23.7 nm, and entrapment efficiency is 88.358%. Optimization of phenylbutazone levels was obtained at a concentration of 0.1% with entrapment efficiency of 88.358%. Conclusion: The optimum level of phenylbutazone in the vesicular carrier ethosome was 0.1%.
