Hard-shell capsules commonly consist of gelatin which is not a universal material considering it extracted from animal parts. Moreover, the mad cow disease triggered scrutinization use in pharmaceutical products. Hence, an alternative to conventional hard-shell needed. Carrageenan- (CRG-) based were successfully prepared by cross-linking CRG with maltodextrin (MD) and plasticizing sorbitol (SOR). These CRG-MD/SOR produced as oral drug delivery system (DDS). The physical properties...

Abstract The release of drugs from solid drug delivery materials has been studied intently in recent years. Quantitative analyses achieved vitro dissolution becomes easier if a zero-order mathematical model is used. Non-gelatin nutraceutical hard-shell capsules zero size (approximately 0.7-0.8 cm) were produced carrageenan-based natural polymers, namely carrageenan-alginate (CA) and carrageenan-starch (CS). Disintegration, kinetics containing 100 mg salicylamide studied. disintegration time...
