Ropivacaine, Epinephrine, Clonidine, and Ketorolac (R.E.C.K) versus Exparel to Improve Pain after Robotic Nephrectomy, RECK EX Trial

Trial Status: active

This phase III trial compares the effect of ropivacaine, epinephrine, clonidine, and ketorolac (R.E.C.K) to Exparel on pain after undergoing surgery to remove part of one kidney or a kidney tumor (partial nephrectomy) or an entire kidney, nearby adrenal gland and lymph nodes and other surrounding tissue (radical nephrectomy). Pain control for patients undergoing surgery can begin in the operating room using regional pain medications. Ropivacaine, a type of local anesthetic, is a drug used to control pain and to cause a temporary loss of feeling in one part of the body, during and after surgery. Epinephrine is in a class of medications called alpha- and beta-adrenergic agonists (sympathomimetic agents). It works by relaxing the muscles in the airways and tightening the blood vessels. Clonidine blocks the release of chemicals from nerve endings that make blood vessels constrict (get narrower). Clonidine is a type of antihypertensive agent and a type of alpha-adrenergic agonist. Ketorolac is in a class of medications called non-steroidal anti-inflammatory drugs. It works by stopping the body's production of a substance that causes pain, fever, and inflammation. Bupivacaine is in a class of medications called local anesthetics. It works by blocking nerves from sending pain signals. Exparel is a form of bupivacaine that is contained inside very tiny, fat-like particles. It slows the release of bupivacaine and may increase the duration of pain relief. Both R.E.C.K and Exparel have a similar purpose and are approved for use in post operative pain care, but the cost of Exparel is significantly more. Giving R.E.C.K may be as effective as Exparel on controlling pain and reducing the use of narcotics after a partial or radical nephrectomy.
