ELECTROSPUN FIBERS HAVING A PHARMACEUTICAL AND METHODS OF MAKING AND USING THE SAME
A fiber may comprise an electrospun polymer and a pharmaceutical. The pharmaceutical may be dispersed within the electrospun polymer, and may have the form of a crystal, an oil, or a combination thereof. A method of making an electrospun fiber may comprise configuring a receiving surface to receive a polymer fiber, applying a charge to one or more of the receiving surface, a polymer injection system, and a polymer solution ejected from the polymer injection system, and depositing a polymer solution ejected from the polymer injection system onto the receiving surface. The polymer solution may comprise a polymer and a pharmaceutical. A method of treating a disorder in a subject may comprise obtaining such a fiber having an effective amount of a pharmaceutical, applying the fiber to an oral region of the subject, and allowing the fiber to disintegrate, thereby delivering the effective amount of the pharmaceutical to the subject.
