Abstract
A coated doughnut-shaped tablet is evaluated as its ability to release model drugs at a zero-order rate for 8 to 12 hours. The doughnut-shape tablets were compressed using special designed punches.Automated technology is thus feasible for this system. The coating material , 10% w /w gelatin in HPMC K15M was directly compressed and adhered to the tablet core .
