Calcium alginate gel-coated pellets were developed by forming an insoluble gel coat on
extruded–spheronized pellets by interfacial complexation. Experiments were designed to …

Spherical pellets containing theophylline, calcium acetate and microcrystalline cellulose
were extruded and spheronized, before being coated with six different pectins or alginates …

Small calcium alginate matrices were prepared by ionotropic gelation of droplets of an
alginate solution containing dispersed theophylline, followed by air-drying of the gel beads …

The aim of this study was examine the rehydration, swelling and drug release behavior of
spherical pellets containing theophylline and coated with two different calcium pectinates …

The natural polymers alginate and chitosan were used for the preparation of controlled
release nicardipine HCl gel microparticles. The e ect of the mannuronic/guluronic acid …

Hydrophilic gels, formed by the interaction of calcium ions with either sodium alginate or
potassium pectinate, can be deposited as a wet coating on to the surface of drug loaded …

release nicardipine HCl gel microparticles. The effect of the mannuronic/guluronic acid …

抄録 Sodium alginate (ALNa) of a natural polysaccharide is known to form a water-insoluble
gel when combined with a bivalent metal. In this study, we prepared tablets containing ALNa …

The aim of this study was to investigate the effect of drug solubility on the release behavior
from calcium polysaccharide gel (CaPG)-coated pellets. Three different drugs with similar …

A novel slow release solid oral dosage system based on sodium alginate (NaAlg) and
sodium calcium alginate (NaCaAlg) has been described (European Patent No. 0188040) …
