Andrographolide (AG), a major active constituent of Andrographis paniculata, is known to hinder proliferation several types cancer cells. However, its poor solubility and cellular permeability restrict use in clinical applications. In this study, AG-loaded phytosomes (AG-PTMs) were formulated optimized with respect particle size using l-α-phosphatidylcholine (PC):AG ratio sonication time (ST) as independent variables. The formula was prepared at 1:2.7 for AG:PC molar 4.9 min ST exhibited...
