Sustained Release Agent

Modified- or sustained-release matrices are designed to release a drug slowly over an extended period of time. Formulations must be robust to ensure drug release over time and avoid dose-dumping. Lipid-based matrices are water-insoluble and do not swell or erode when in contact with aqueous media.…
