Later, in 2020, approved indications were extended also to ankylosing spondylitis, psoriatic arthritis, psoriasis, Crohn’s disease (CD) and ulcerative colitis (UC). The present review provides summary of the key features of SC infliximab, with particular focus on pharmacokinetic profile, clinical development program in comparison with the intravenous (IV) formulation, and the latest evidence in the literature. We conclude that SC infliximab represents a new and promising approach in the treatment of patients with RA, offering an optimized clinical profile and a more practical option in comparison to the IV formulation. Nevertheless, SC formulation can improve the use of national health systems resources (e.g., through the time of healthcare workers not having to supervise infusions) and facilitate social distancing measures during the COVID-19 pandemic, as the patient can self-inject the medicine at home without going to the hospital. The limitations of the SC infliximab are mainly due to the limited experience of use in clinical practice and the absence of long-term drug retention data.Keywords: rheumatoid arthritis, TNF inhibitors, infliximab, subcutaneous, intravenous, SC, IV, RA |
