Modified-release tablets matrix system

Hydroxypropyl starch is a modified starch and has been used in combination with carrageenan in the production of soft capsules. " Hydroxypropyl starch has been used experimentally in hydrophilic matrices, where it was shown to be an effective matrix for tablets designed for controlled-release drug delivery systems. It has also been used experimentally in the production of hydrophilic matrices by direct compression. ... [Pg.344]

The process of water penetration into hydrophilic matrix tablets was also studied using a modified Enslin apparatus. This apparatus contains a fritter and a system to regulate the water level. When the tablet is placed on the fritter, the water is absorbed from a reservoir which is placed on a precision balance. The amount of water uptake at each time point was read from the balance as weight loss in the reservoir. Figure 46 shows the obtained release profiles. [Pg.1042]
