The development of artificial surfactants for the treatment
of respiratory distress syndrome (RDS) requires lipid systems that can
spread rapidly from solution to the air-water interface. Because
hydration-repulsion forces stabilize liposomal bilayers and oppose
spreading, liposome systems that undergo geometric rearrangement from
the bilayer (lamellar) phase to the hexagonal II (HII)
phase could hasten lipid transfer to the air-water interface through
unstable transition intermediates. A liposome system containing
dipalmitoylphosphatidylcholine was designed; the system is stable at
23°C but undergoes transformation to the HII phase as the
temperature increases to 37°C. The spreading of lipid from this
system to the air-water interface was rapid at 37°C but slow at
23°C. When tested in vivo in a neonatal rabbit model, such systems
elicited an onset of action equal to that of native human surfactant.
These findings suggest that lipid polymorphic phase behavior may have a
crucial role in the effective functioning of pulmonary surfactant.
