Another method by which sustained release is achieved is through an osmotic controlled-release oral delivery system , where the active compound is encased in a water-permeable membrane with a laser drilled hole at one end.
The extended-release formulations (sometimes called "sustained release", or "enteric coated") take longer to take effect than the immediate-release formulations and therefore are less useful when immediate pain relief is desired. Extended-release formulations are more useful for the treatment of chronic, or long-lasting, conditions, in which ...
