Extrusion-spheronization and pellet compression are effective means of developing first-order kinetic, controlled-release drug delivery systems of azithromycin (AZI). The authors prepared, evaluated, and optimized AZI formulations and assessed the stability of the selected formulation under accelerated storage conditions.
