Potential role of NSAIDs loaded nano-formulations to treat inflammatory diseases

Inflammation is a necessary immunological response that promotes survival and preserves tissue homeostasis, a common characteristic linked to various diseases. However, in some circumstances, the inflammatory response is deleterious and contributes to disease pathogenesis. Anti-inflammatory substances have poor affinity for inflamed tissues, resulting in low concentrations in the target tissue and a higher incidence of severe adverse effects. To address this issue, several potential approaches have been proposed, such as chemical modification of drug molecules and the development of nanocarriers for drug delivery. Since the development of nanotechnology at the beginning of the twenty-first century, researchers have been using the pathophysiological characteristics of inflammation, primarily leaky vasculature, and biomarker overexpression to develop nanomedicines that can deliver therapeutics via passive and active targeting mechanisms to sites of inflammation and produce therapeutic effects. Drug carriers based on nanoparticles can enhance the safety and efficacy of drugs by increasing their capacity, enhancing their solubility, combining several drugs, protecting them from metabolism, and regulating their release. An approach that shows promise in the treatment of various inflammatory diseases is the application of nanomedicines. Nanomedicine involves nanoparticles that have been loaded with a therapeutically active component. Nanomedicines can target inflammation by recognizing molecules highly expressed on endothelial cells or activated macrophage surfaces, enhancing the permeability of vessels, or even by biomimicry. A review of the research findings shows significant potential for the use of nanotechnology to enhance the quality of life for people using NSAIDs for chronic disorders by minimizing drug side effects or the duration of administration. After a brief introduction to inflammation, its various forms- acute and chronic inflammation, and the pathophysiology of inflammation, this review highlights the main innovative nanocarriers utilized for carrying various nonsteroidal anti-inflammatory drugs that have been utilized in treating various inflammatory disorders.
