liposomal

(LY-poh-SOH-mul)
A drug preparation that contains the active drug inside very tiny, fat-like particles. This form is easier for the body to absorb and allows more drug to get to the target area of the body, such as a tumor. Liposomal drugs may have fewer side effects and work better than other forms of the drug.
