Abstract
Liposomes of uniform size are produced by forming liposomes in relatively random sizes, and extruding the liposomes under pressure through a uniform-pore-size membrane to force at least some of the liposomes into smaller sizes. Extrusion may be repeated to increase uniformity of the liposomes. The liposomes may contain an encapsulated drug.
