Modified release formulations films

Hydroxypropyl cellulose (HPC) is a non-ionic water-soluble and pH insensitive cellulose ether. It can be used as thickening agent, tablet binder and modified release and film coating polymer. Buccal delivery formulations containing HPC and polyacrylic acid are used for many years and is used for mucoadhesive delivery systems for several drugs. [Pg.54]

It is a rare circumstance when a coating formulation contains only the primary filmforming polymer. Most often, film coating formulations contain one or more functional additives included to facilitate the spraying process, improve film coal appearance, improve post-process handling, and/or to modify drug release characteristics. In this section, the various classes of functional additives for film coating will be reviewed with respect to the different excipients and their particular functionality. [Pg.402]
