The optimum colonic drug delivery ZPG/tablet system provided the expected delayed-release sigmoidal patterns with a lag-time of 4.125–4.85 h and t 50% (the time for 50% of the drug to be released) at 7.45–8.70 h, depending on pectin/dextran ratio employed. The results also demonstrated that the untableted ZPG microparticles exhibited drug ...Author: Ibrahim El-Gibaly
