In recent years worldwide interest has grown towards the development of mucoadhesive drug delivery systems. These systems are capable of adhering to body's mucosal surfaces for an extended period of time, releasing their drug content in a retarded manner. The use of biopolymers, and in particular phytopolymers, could provide a natural basis for the development of such systems. The aim of this s...

this paper is the first multi-scale characterization of the fluidize-dried gum extracted from the fresh fruits of the plant abelmoschus esculentus. it describes the physical, thermal, sorptional and functional properties of this natural gum. elemental analysis, scanning electron microscopy (sem), particle size analysis, x-ray powder diffraction (xprd), thermo-gravimetric analysis (tga), differe...

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...

The aim of this study was to compare chemical composition, relative feed values, and in vitro true digestibility the giant fennel (Ferula communicus L. -F), helis (Prangos ferulacea -H), gum- tragacanth (Astragalus microcephalus WILD. -G) leaves oak tree (Quercus robur -O), a naturally growing plant on high- altitude plateaus Eastern Anatolia, with those alfalfa. In digestibilities (IVTD) rough...

Buccal matrices represent a widely accepted dosage form permitting convenient, easy, reliable drug administration and reducing errors. The aim of this study was the development mucoadhesive buccal for propranolol in children. Matrices were obtained by freeze-drying loaded polymeric solutions based on gum tragacanth (GT), pectin (PEC), hydroxypropylmethylcellulose (HPMC), sodium hyaluronate (HA)...
