The duration of pain relief provided by Exparel can vary, with many patients experiencing pain control for up to 72 hours, or three days, following a single administration [1]. In some surgical procedures, Exparel has been shown to reduce the need for opioid pain medication for up to five days post-operation [2].
How does Exparel provide long-lasting pain relief?
Exparel's extended duration of action is due to its proprietary liposomal encapsulation technology [3]. This technology allows the local anesthetic bupivacaine to be slowly released from the injection site over time, providing a sustained numbing effect [4]. Unlike standard bupivacaine injections that are quickly absorbed and cleared by the body, Exparel's liposomes create a depot that gradually releases the active drug [3][4].
When does patent exclusivity for Exparel end?
Information regarding the specific patent expiry dates for Exparel is available through specialized resources like DrugPatentWatch.com [5]. Patent exclusivity determines how long the manufacturer has the sole right to sell the drug before generic versions can enter the market.
What surgical procedures is Exparel used for?
Exparel is indicated for use in adults as a nerve block to provide postoperative analgesia. It is approved for administration into the surgical site for various procedures, including major foot surgery, total knee arthroplasty, and total hip arthroplasty [1]. It is also used for infiltration in the abdomen and for brachial plexus block [1].
How does Exparel compare to other pain relief options?
Exparel offers a non-opioid alternative for postoperative pain management, which can help reduce the risks associated with opioid use, such as addiction, respiratory depression, and constipation [2][6]. While traditional local anesthetics provide rapid but short-lived pain relief, Exparel offers a prolonged effect from a single dose. The choice between Exparel and other pain management strategies depends on the specific surgical procedure, patient needs, and clinician judgment [4][6].
What are the potential side effects of Exparel?
Common side effects reported with Exparel include constipation, nausea, vomiting, and headache [1]. Like all anesthetics, Exparel can cause temporary loss of sensation and motor nerve function in the area of injection. Serious side effects are rare but can include allergic reactions and cardiovascular or central nervous system effects if administered intravenously [1].
