[New technological strategies for drug administration in the treatment of joint pathologies]

Despite the availability of drugs and pharmaceutical forms for the treatment of rheumatoid arthritis and osteoarthritis symptoms, their adverse effects and lack of response to therapy reinforces the need to search for new technological formulation strategies capable of delaying the progress of the disease, with better therapeutic results and prolonged control of arthropathy. The aim of this bibliographic review was to identify new reported therapeutic approaches for these diseases. The treatment of rheumatoid arthritis and osteoarthritis is an unresolved challenge, due to the complexity of these diseases. Thus, the new therapies aim to suppress inflammatory mediators and to reduce the degradation of the extracellular matrix. In addition, the use of nano and microtechnology takes advantage of the properties of polymers, lipids, peptides, and nucleic acids to develop controlled drug release systems, aiming to obtain highly effective precision therapies, whose usefulness should be evaluated in future clinical trials.
