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

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 …

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

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 …

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 …

This study aimed to evaluate the potential of applying pectin and chitosan polysaccharides
in pellet formulation. These biopolymers have advantages such as biocompatibility, low …

Sažetak The aim of this work was to evaluate gellan gum as binder in pellet formulations,
with theophylline as the model drug, in comparison with polyvinylpyrrolidone (PVP). A full 32 …

The aim of this study was to investigate the in vitro drug-release behavior of theophylline
pellets coated with différent films, pectin or calcium pectinate. To obtain the ratio of calcium …

Sažetak Pellets containing theophylline as a model drug and microcrystalline cellulose, in a
ratio of 6: 4, were prepared by extrusion-spheronization method. The pellets were coated …

A conventional method of using drug entrapped in calcium pectinate beads as sustained
release drug delivery systems have long been suffering from too rapid an in-vitro release. An …
