Abstract

Liposome defined as a spherical vesicle, which is formed when phospholipids are being hydrated with an aqueous environment. This study investigated the role of HPMC to inhibit mannitol crystallization in the air-dried liposome formulation. HPMC has been used in solid dispersion to prevent crystallization drugs. The mannitol and HPMC were included in the developed formulations with four different ratios and air-dried at 40ºC for 120 h. Liposome was composed of SPC:DDA: Chol (9:3:1 in molar ratio). XRD data showed crystalline-forming properties as a function of mannitol and HPMC ratio. The formula with the highest mannitol: HPMC ratio (4:1) showed the most apparent crystallinity, while the lowest proportion (2:3) indicated amorphous solid. DTA analysis found that the following formula showed a broad endothermic peak at 150-170ºC, indicating amorphous solid. SEM data supported these results where no crystalline structure was observed in the latter formulation. The rest formula showed partially amorphous and partially crystalline. It can be concluded that the incorporation of HPMC as a dispersion matrix potentially inhibits crystal formation in the developed formulation
