To reduce mucosal damage in the gastrointestinal tract caused by aspirin. we developed a dissolvable polymeric microneedle (MN) patch loaded with aspirin. Biodegradable polymers provide mechanical strength to the MNs. The MN tips punctured the cuticle of the skin and dissolved when in contact with the subcutaneous tissue. https://northwerstknivers.shop/product-category/automatic-knife/
