Outline of stability study for erythromycin-loaded cinnamon oil-based transethosomal emulgel in comparison to freshly prepared formulation at 25 °C (a,c,e) and 4 °C (b,d,f). The effects were determined on pH and viscosity (a,b), extrudability and spreadability (c,d), percentage of drug content and percentage of drug release (e,f).
