Non-steroidal anti-inflammatory drugs (NSAIDs) and selective cyclooxygenase (COX)-2 inhibitors are commonly used to control pain and inflammation in osteoarthritis. However, these agents have been associated with gastrointestinal, renal and cardiovascular adverse effects. Together, these complications indicate a clear unmet need in the safety of current treatment options for the management of osteoarthritis. ⋯ With the current unmet needs in the treatment of osteoarthritis, the opportunity exists for the development of new therapies. Novel agents include the COX-inhibiting nitric oxide donors and the lipoxygenase (LOX)/COX inhibitor licofelone. Initial results suggest that these therapies may have tolerability advantages over the NSAIDs and selective COX-2 inhibitors.
