titleOfInvention | CONTROLLED MEDICINAL ADMINISTRATION SYSTEM, OF ZERO ORDER. |
abstract | A controlled release dosage form is provided comprising: (i) a tablet core comprising a pharmaceutically active ingredient and one or more pharmaceutically acceptable matrix-forming polymers, (ii) a substantially insoluble shell that extends over the core of tablet covering between 25 and 99% of the surface area of the tablet core, similar, for example, to a coverage of only the main surfaces similar to that shown in Figure 1 or on the main surface and side walls, similar to that shown in Figure 2, the cover results from the electrostatic deposition of a powder comprising fusible particles on the tablet core and fusion of the particles to form a thin film so that the electrostatically coated tablet releases the active ingredient with an active ingredient release profile for zero to at least 50% by weight ingredient release asset defined by the equations y = k * tn which and is the percentage of active ingredient released k is the kinetic constant t is time n is the release exponent and n is in the range of 0.70 to 1.0, ie , an approximately zero order release profile. |
