Abstract
Disclosed herein are vesicle compositions for controlled sustained release of an encapsulated therapeutic agent after parenteral administration. By adjusting the 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.
