Vesicle formulations for the controlled release of therapeutic agents.

摘要

Vesicle compositions provide controlled sustained release of an encapsulated therapeutic agent after parenteral administration, depending upon the difference in osmolarity between the suspending solution and the solution within the vesicles. By adjusting the concentration of the suspending solution, the rate of release of the therapeutic agent after parenteral administration can be varied. The compositions can be effectively administered by intramuscular, subcutaneous injection or other means.
