Electrospun fibers as potential carrier systems for enhanced drug release of perphenazine.

Solubility represents an important challenge for formulation of drugs, because the therapeutic efficacy of a drug depends on the bioavailability and ultimately on its solubility. Low aqueous solubility is one of the main issues related with formulation design and development of new molecules. Many drug molecules present bioavailability problems due to their poor solubility.

Fabrication, Physico-Chemical, and Pharmaceutical Characterization of Budesonide-Loaded Electrospun Fibers for Drug Targeting to the Colon.

The objective of this study was to fabricate and characterize electrospun fibers loaded with budesonide with the aim of controlling its release in the gastrointestinal tract. Budesonide is a nonhalogenated glucocorticosteroid drug, highly effective in the treatment of some inflammatory bowel diseases with local action throughout ileum and colon. At this aim, Eudragit® S 100, a polymer soluble at pH > 7, commonly used for enteric release of drugs, has been successfully spun into ultrafine fibers loaded with Budesonide (B) at 9% and 20% (w/w) using the electrospinning process.

Polymorphic solidification of Linezolid confined in electrospun PCL fibers for controlled release in topical applications.

Poly(ϵ-caprolactone) (PCL) membranes loaded with Linezolid, chemically N-[[(5S)-3-[3-fluoro-4-(4-morpholinyl)phenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide (empirical formula C16H20FN3O4) have been prepared by electrospinning technique, at different Linezolid concentrations (0.5, 1, 2.5 and 5%, w/w).
