The cause of CRPS is unknown, but it is generally thought to be the result of the body reacting abnormally to an injury. It is difficult to estimate exactly how common CRPS is, as many cases may go undiagnosed or misdiagnosed. Currently there are no approved treatments for CRPS. Neridronic acid administered by injection is currently being developed to treat CRPS and early results indicate that it has the possibility to control the condition. If approved neridronic acid will be a potential new treatment for CRPS.
Bupivacaine and meloxicam (HTX-011) in a fixed-dose combination is in development for the management of post-operative pain. Post-operative pain is a typical example of acute pain. Acute pain typically lasts for less than 3-6 months (unlike chronic pain which carries on for longer than 12 weeks), and is provoked by identifiable stimuli and disappears as soon as the tissue injury or damage that had caused it is healed. All surgical procedures are associated with a certain level of post-operative pain. Opioids are often used to manage post-operative pain but carry the risk of harmful side effects, abuse and addiction.
