AcelRx Pharmaceuticals Announces Publication Concluding that Sublingual Sufentanil Tablets Provide the Opportunity to Non-Invasively and Rapidly Treat Moderate-To-Severe Acute Pain in a Monitored Setting

REDWOOD CITY, Calif., April 18, 2018 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, announced the publication of an analysis of the pharmacokinetic characteristics of sublingually administered tablets containing 15 or 30 mcg of sufentanil in a special "Frontiers in Opioid Pharmacotherapy" edition of the peer-reviewed journal, Anesthesiology.  The manuscript reports on the results of pharmacokinetic analyses using blood sampled from both healthy subjects and surgical patients in AcelRx clinical trials in order to determine the effects of weight, age, sex, and organ impairment on apparent clearance of sufentanil from plasma following tablet administration.

The study concluded that sublingual sufentanil tablets provide the opportunity to non-invasively and rapidly treat moderate-to-severe pain in a monitored setting. Following dosing of the 30 mcg sufentanil sublingual tablet, therapeutic sufentanil plasma concentrations were reached within 30 minutes and remained above this level for approximately 3 hours, consistent with the onset and duration of analgesia observed in the clinical trials. The results also indicated that drug clearance, which increased slightly with weight and decreased slightly with age, was not affected by sex of the patient or by hepatic or renal impairment.

"The current standard of care to treat moderate-to-severe acute pain via IV opioid administration can delay pain relief or require unnecessary IV access for patients," commented Dr. Dennis Fisher, lead author of the study.  "The onset and duration of therapeutic sufentanil plasma concentrations matches nicely with the analgesic needs in short-term medically monitored settings, such as the emergency room or ambulatory surgery centers."
