Increasing sodium pantoprazole photostability by microencapsulation: Effect of the polymer and the preparation technique

Microencapsulation of Lemongrass (Cymbopogon citratus) Essential Oil Via Spray Drying: Effects of Feed Emulsion Parameters

“…In food applications, microencapsulation is feasible to improve the stability of essential oils. Microcapsule walls commonly consist of polymeric materials, which are prepared by different chemical and physical methods, such as spray drying [9], precipitation [10], coacervation [11], dissolving [12] and solid complexation [13]. Among them, spray drying is the most usually applied encapsulation technique for food products.…”

Production of pH-Responsive Microparticles by Spray Drying: Investigation of Experimental Parameter Effects on Morphological and Release Properties

“…However, despite a large number of experimental investigations4–6 and mathematical modelling,1,7–9 the mechanisms of droplet drying and drug incorporation are not fully understood and remain difficult to predict. In simple terms, as the evaporating droplet shrinks, its receding droplet surface leads to increased solute concentration at the surface with consequent diffusional flux to the centre 10.…”

Microencapsulation of sodium alendronate reduces drug mucosal damage in rats

“…The advantages of the drug release rate manipulation by using polymer blend microparticles have been previously reported (Blanco-Prieto et al, 2004;Lionzo et al, 2007;Poletto et al, 2007), and a successful approach developed in our group showed that gastroresistance and controlled release microparticles containing pantoprazole, an anti-ulcer agent, can be prepared using Eudragit ® S100 and hydroxypropyl methylcellulose (HPMC) (Raffin et al, 2006;2008).…”
