Coaxial Electrospray of Curcumin-Loaded Microparticles for Sustained Drug Release

Curcumin exhibits superior anti-inflammatory, antiseptic and analgesic activities without significant side effects. However, clinical dissemination of this natural medicine is limited by its low solubility and poor bio-availability. To overcome this limitation, we propose to encapsulate curcumin in poly(lactic-co-glycolic acid) (PLGA) microparticles (MPs) by an improved coaxial electrospray (CE...

Fabrication of Bovine Serum Albumin-Loaded Coaxial Electrospun Thread with an Aligned Core-Shell Fibrous Structure

Au Nanoparticle Loaded with 6-Thioguanine Anticancer Drug as a New Strategy for Drug Delivery

In this study we suggested a new strategy for drug delivery of 6-thioguanine (6-TG) as a cancer drug by loading of this thiolic drug at a surface of Au nanoparticles. For this goal, we synthesized Au nanoparticle (Au/NPs) by reduction of tetrachloroauric (III) acid solutions by sodium borohydride and characterized Au/NPs by X-ray powder diffraction (XRD), dynamic light scattering (DLS), Ultravi...

An oral malaria therapy: curcumin-loaded lipid-based drug delivery systems combined with β-arteether.

Curcumin (CC), a potential antimalarial drug, has poor water solubility, stability and oral bioavailability. To circumvent these pitfalls, lipid-based drug delivery systems (LBDDSs) with a high CC loading (30 mg/g) were formulated. In a biorelevant gastric medium, CC-LBDDSs formed particle sizes in the range of 30-40 nm. During in vitro lipolysis, 90-95% of the CC remained solubilized, whereas ...

Alginate-Based Composite Sponges as Gastroretentive Carriers for Curcumin-Loaded Self-Microemulsifying Drug Delivery Systems

Alginate-based composite sponges were developed as carriers to prolong the gastric retention time and controlled release of curcumin-loaded self-microemulsifying drug delivery systems (Cur-SMEDDS). Liquid Cur-SMEDDS was incorporated into a solution made up of a mixture of polymers and converted into a solid form by freeze-drying. The ratio of alginate as the main polymer, adsorbent (colloidal s...
