CURRENT ADVANCES IN SUSTAINED-RELEASE INJECTABLE PREPARATIONSAbstract
In recent years, there has been a great deal of interests in developing sustained-release systems which can prolong the therapeutic effect, decrease adverse side effects, and reduce administration frequency. Nowadays, the oral sustained-release preparations account for a larger market share comparing to other sustained-release forms, mainly because of its noninvasive pain-free administration. However, the hostile environment of gastrointestinal tract and first-pass effect may lead to low bioavailability of some drugs, such as some proteins, peptides, and hormones. In this paper, the latest research progresses of some new-model sustained-release injectable dosage forms were introduced, including microsphere, microcapsule, liposome, polymeric micelle, and in situ forming system.
