The drug release profile from calcium-induced alginate gel beads coated with an alginate hydrolysate.
Calcium-induced alginate gel bead (Alg-Ca) coated with an alginate hydrolysate (Alg), e.g. the guluronic acid block (GB) was prepared and the model drug, hydrocortisone release profiles were investigated under simulated gastrointestinal conditions. Their molecular weights were one sixth or one tenth that of Alg and the diffraction patterns of the hydrolysates resembled that of Alg. The drug rel...
متن کاملPreparation of Uniform Calcium Alginate Gel Beads by Membrane Emulsification Coupled with Internal Gelation
With the objective of making calcium alginate gel beads with small and uniform size, membrane emulsification coupled with internal gelation was proposed. Spherical gel beads with mean size of about 50 m, and even smaller ones in water, and with narrow size distribution were successfully obtained. Experimental studies focusing mainly on the effect of process parameters on bead properties were pe...
متن کاملHydrophilic Natural Polymers for Sustained-controlled Release of Calcium Hydroxide
Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH chan...

متن کاملEvaluation of tetrandrine sustained release calcium alginate gel beads in vitro and in vivo.
An approach for the preparation of tetrandrine sustained release calcium alginate gel beads was described. In vitro the release of tetrandrine from sustained release dosage forms went on a time of 12 hours which fitted non-Fickian diffusion with matrix erosion significantly. In vivo the plasma concentration of tetrandrine extended preparation given in dogs reached Cmax 2.67+/-0.69 microg/ml app...
