A novel methodology for delivering variable drug concentration profiles utilizes a combination of liposomes that destabilize at different rates at body temperature (37° C). Liposomes serve as the mobile drug delivery vehicle and release drugs into the body upon destabilization. Liposome destabilization is studied by monitoring the absorbance spectrum of fluorescent dyes. By combining liposomes of various compositions, concentration profiles that are optimized and tailored to specific patients and applications are feasible.
