“We are excited to announce the approval of POSIMIR, a novel, non-opioid, sustained-release local analgesic for the treatment of post-surgical pain following arthroscopic subacromial decompression surgery,” said
“In my experience, POSIMIR was easy to administer into the subacromial space under arthroscopic guidance, where it can directly address the source of postsurgical pain,” said
“The first 72 hours after surgery are typically when patients experience the most severe postsurgical pain,” said T J Gan, MD MHS FRCA MBA, Professor and Distinguished Endowed Chair,
POSIMIR (bupivacaine solution) for infiltration use is a novel and proprietary product that combines the strength of 660 mg of bupivacaine base with the innovative SABER® platform technology, enabling continuous sustained delivery of a non-opioid local analgesic over 3 days in adults. POSIMIR contains more bupivacaine than any other approved single-dose sustained-release bupivacaine product. At the end of surgery, POSIMIR is administered into the subacromial space under direct arthroscopic visualization, where it continuously releases bupivacaine for 72 hours or more.
About Subacromial Decompression Shoulder Surgery
Subacromial decompression is a type of shoulder surgery used to treat impingement syndrome, a common repetitive-use injury that causes pain when the arm is raised over the head. The procedure is typically performed arthroscopically, meaning that several small incisions are made in the skin and muscle of the shoulder through which a camera lens (arthroscope) and surgical instruments are inserted during surgery. Arthroscopic subacromial decompression is generally considered outpatient surgery, and most patients go home within a few hours of surgery. The recovery period may extend from weeks to months, but the most intense pain typically occurs during the first 3 days after surgery and is often managed with oral opioids. There are over 600,000 surgeries involving arthroscopic subacromial decompression performed each year in the
In connection with this approval, the Company or its licensee, will be required to conduct two postmarketing non-clinical studies.
Indications and Usage
POSIMIR (bupivacaine solution) for infiltration use is indicated in adults for administration into the subacromial space under direct arthroscopic visualization to produce post-surgical analgesia for up to 72 hours following arthroscopic subacromial decompression.
Limitations of Use
Safety and effectiveness have not been established in other surgical procedures, including soft tissue surgical procedures, other orthopedic procedures, including for intra-articular administration, and boney procedures, or when used for neuraxial or peripheral nerve blockade.

Important Safety Information
BOXED WARNING: Risk of Potential Adverse Embolic Effects Resulting From Inadvertent Intravascaular Injection. Inadvertent intravascular injection could cause POSIMIR droplets to be deposited in the pulmonary and other capillary beds. Administer POSIMIR into the subacromial space at the end of arthroscopic shoulder surgery. Direct arthroscopic visualization must be used to confirm proper placement of the needle tip before injecting POSIMIR.
In POSIMIR clinical studies, no inadvertent intravascular injections were observed. Do not inject POSIMIR intravascularly.
POSIMIR is contraindicated in patients with a known hypersensitivity to any amide local anesthetic, or other components of POSIMIR, as well as in patients undergoing obstetrical paracervical block anesthesia. There is a risk of joint cartilage necrosis with unapproved intra-articular use of POSIMIR. Unintended intravascular injection of POSIMIR may be associated with systemic toxicities, including CNS or cardiorespiratory depression and coma, progressing ultimately to respiratory arrest. As with other local anesthetics, patients should be monitored for central nervous system, cardiovascular, and allergic reactions. Avoid additional use of local anesthetics within 168 hours following administration of POSIMIR. Cases of methemoglobinemia have been reported in association with use of local anesthetics. There have been reports of chondrolysis (mostly in the shoulder joint) following intra-articular infusion of local anesthetics, which is an unapproved use. POSIMIR should be used cautiously in patients with impaired hepatic and cardiovascular function. Adverse events reported with an incidence greater than or equal to 10% and greater than control following POSIMIR administration in shoulder surgery were dizziness, dysgeusia, dysuria, headache, hypoesthesia, paresthesia, tinnitus, and vomiting. Adverse events reported with an incidence greater than or equal to 10% and greater than control following POSIMIR administration in soft tissue surgical procedures were anemia, bradycardia, constipation, C-reactive protein increased, diarrhea, dizziness, dysgeusia, headache, nausea, oropharyngeal pain, post-procedural contusion (bruising), procedural pain, pruritus, pyrexia, somnolence, surgical site bleeding, visible bruising and vomiting.
