Abstract
Disclosed are devices for delivering a rheumatoid arthritis drug across a dermal barrier. The devices include microneedles for penetrating the stratum corneum and also include structures fabricated on a surface of the microneedles to form a nanotopography. A random or non-random pattern of structures may be fabricated such as a complex pattern including structures of differing sizes and/or shapes. The pattern of structures on the surface of the microneedles may include nano-sized structures.
Claims11
A method for forming a device for delivery of a rheumatoid arthritis drug across a dermal barrier, the method comprising:
- fabricating an array of microneedles;
- fabricating a pattern of first nanostructures on and projecting outward from a surface of at least one of the microneedles, wherein the pattern of first nanostructures comprises a fractal and/or fractal-like geometry,
- associating the rheumatoid arthritis drug with the microneedles such that the rheumatoid arthritis drug is in fluid communication with the microneedles.
