Abstract:
Several technologies to control drug release from oral dosage forms have been developed. Drug release can be regulated in several ways: sustained release, whereby the drug is released slowly over a prolonged period of time, postponed release, whereby drug release is delayed until passage from the stomach into the intestine (via enteric coating), and targeted release, whereby the drug is targeted to a specific location of the gastrointestinal tract. This article reviews the various oral controlled release dosage forms on the market.
