Abstract In this work, a bottom-up approach based on the study of polyelectrolyte interactions was performed in order to evaluate the effect of Prosopis alba exudate gum as novel excipient for fish oil encapsulation in composed calcium-alginate-chitosan beads. Emulsion and beads properties such as oil distribution, encapsulation efficiency, yield, microstructure and thermo-oxidative protection were evaluated. Alginate and gum exert a synergistic effect on emulsion stability properties, which...

Abstract Objectives: The work objective was to study the possible effects of different pharmaceutical excipients on the release of sodium salicylate from oily vehicles. Methods: Several formulations of Fractionated Coconut Oil (FCO) containing different pharmaceutical additives were prepared. The release rate behaviour of sodium salicylate from these oily formulations was investigated using a dialysis method. The time required for 30% and 50% of the salicylate to appear in solution outside the...

Aim: The aim of this work is development and evaluation of chlorhexidine medicated chewing gums by different methods and to study the influence of different plasticizers and methods on physicochemical parameters and in vitro drug release profile. Materials and Methods: Chlorhexidine is an antibacterial agent used for management of tooth decay. The formulations are prepared with varying concentrations of plasticizers and synthetic gum base by different methods such as direct compression and...

To study the effect of hydrophobic modification of the emulsifier on the relationship between emulsion stability and polymer emulsifier concentration, silicone oil emulsions were prepared using by hydroxypropyl methylcellulose (original HPMC) and HPMC stearoxy ether (hydrophobic HPMC) at concentrations around their overlap concentrations. Both HPMC types completely emulsified the silicone oil. However, the volume fraction of silicone oil in the emulsion prepared using hydrophobic HPMC was less...

Conversion of liquid and semisolid lipids into free flowing powders is an advantageous technique, as the carriers display high surface area, strong adsorption capacity, ease of processing, and ability to generate lipid loaded free flowing powders which can be converted to solid dosage forms like tablets and capsules. A combination of density, adsorption capacity and desorption is found to be of importance in the selection of the right adsorbent. Adsorbents like magnesium aluminium silicates...

The aim of current research was to develop and characterize solid self-emulsified nanostructures (S-SEN) loaded with a BCS class II drug, Lercanidipine hydrochloride (LCH). The liquid self-emulsified nanostructures (L-SEN) were prepared using rice bran oil and glyceryl monooleate (GMO) as oil phase and Tween 80 and propionic acid as surfactant and co-surfactant respectively.

Introduction: Choline bitartrate (CBT) is a vital nutrient for fetal brain development and memory function. It is hygroscopic in nature which is associated with stability related problem during storage such as development of fishy odor and discoloration. Aim: Microencapsulation method was adopted to resolve the stability problem and for this hydrogenated soya bean oil (HSO) was used as encapsulating agent. More

Spray drying is an important method in the food industry for the production of encapsulated oil to improve the handling and flow properties of the powder. In this study, the effect of mixture of polymers on the encapsulation of fish oil by spray drying was investigated. Fish oil powder were produced using different ratios of mixtures of hydroxypropyl methylcellulose (HPMC) 15 cps and HPMC 5 cps. More
