Abstract
A nifedipine formulation for oral administration is described that provides controlled, constant release of the pharmaceutical for about twenty four hours after a short delay following oral administration. There is also provided a method for preparing a controlled release formulation of nifedipine, which method includes coating pellets with multiple nifedipine-containing layers, along with an outer controlled release coating comprised of a water permeable polymer and lubricant/glidant. The pellets are then cured at an elevated temperature over several days. A method of using the formulations of the present invention for the treatment of patients is also described.
