REDWOOD CITY, Calif., April 13, 2017 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of moderate-to-severe acute pain, announced that Grunenthal, the company's licensee for ZALVISO® in Europe and Australia, has published two analyses of patient-controlled analgesia (PCA) systems in the peer-reviewed journal, Current Medical Research and Opinion. These manuscripts were based on a systematic literature review of efficacy, safety and tolerability results from studies that were published between 2004 and 2015 of three routes of PCA administration: intravenous (IV) PCA with morphine, transdermal PCA with fentanyl and sublingual sufentanil delivered via ZALVISO. Patients enrolled in these studies had moderate-to-severe acute post-operative pain following surgical procedures such as knee or hip replacement, open abdominal, cardiac, brain, lower limb orthopedic and chest surgery.

"We know that severe pain after surgery contributes to the development of chronic pain. It is therefore critical that post-operative acute pain is addressed so that patients may regain mobility, which may in turn facilitate their recovery, reduce length of stay and lessen the risk of complications," commented Dr. Pamela Palmer, co-founder and chief medical officer of AcelRx and a co-author on the Current Medical Research and Opinion papers. "While the analyses in these two papers were conducted via literature review and therefore convey only indirect findings, the conclusions may still be useful to healthcare providers in their assessment of patient-controlled analgesia options."
