Abstract
Temperature sensitive liposomes containing active agents are described. The liposomes comprise phospholipids and a surface active agent, such as a lysolipid, that increases the amount of active agent released by the liposome at the phase transition temperature of the liposome. Such liposomes are useful in methods of administering active agents using mild hyperthermic conditions.
