Advantages and disadvantages of liposomes as an oral delivery system.

Advantages	Disadvantages
Biocompatibility	Physical instability in liquid state
Versatility for drug encapsulation	Lysolipid formation by chemical degradation
Flexibility of membrane components	Drug leakage
Capability of surface modification	Disruption in the stomach
Proposed enhanced permeation	Low permeability of intact liposome in the GI tract
Modifiable pharmacokinetic behavior	Difficulty in mass production and quality control
