Abstract
Described are drug delivery systems incorporating electrospun fibers that comprise and deliver physicochemically diverse drug compounds. Such fibers provide significant advantages in drug agent release, such as adaptability for solid dosage delivery to mucosal tissues. This is in addition to allowing for controlled drug release. Systems and methods for large-scale electrospinning productivity are described, including novel microarchitectures allowing for variable pharmacokinetics in drug release.
