The development of oral dosage forms for poorly water-soluble active pharmaceutical ingredients (APIs) is a persistent challenge. A range of methods has been explored to address this issue, and amorphous solid dispersions (ASDs) have received increasing attention. ASDs are typically prepared by starting with a liquid precursor (a solution or melt) and applying energy for solidification. Many techniques can be used, with the emergence of electrospinning as a potent option in recent years. This...

Abstract Control of drug action through formulation is a vital and very challenging topic within pharmaceutical sciences. Cellulose nanofibers (CNF) are an excipient candidate in pharmaceutical formulations that could be used to easily optimize drug delivery rates. CNF has interesting physico-chemical properties that, when combined with surfactants, can be used to create very stable air bubbles and dry foams. Utilizing this inherent property, it is possible to modify the release kinetics of the...

Abstract Nanofibers combined with an antimicrobial represent a powerful strategy for treatment of various infections. Local infections usually have a low fluid volume available for drug release, whereas pharmacopoeian dissolution tests include a much larger receptor volume. Therefore, the development of novel drug-release methods that more closely resemble the in-vivo conditions is necessary. We first developed novel biocompatible and biodegradable chitosan/polyethylene oxide nanofibers using...

Nanofibers represent an attractive novel drug delivery system for prolonged and controlled release. However, sustained release of hydrophilic drugs, like ciprofloxacin hydrochloride (CIP), from polymeric nanofibers is not an easy task. More
