FAQs

1. How does EXPAREL compare with traditional local anesthetics?
EXPAREL's liposomal formulation provides extended duration of analgesia (up to 72 hours), reducing the need for additional dosing compared to standard bupivacaine solutions, enhancing postoperative pain control.

2. What are the main regulatory challenges facing EXPAREL?
The primary challenges include maintaining patent protections, expanding indications through clinical trials, and securing approvals in emerging markets with differing regulatory standards.

3. How is reimbursement influencing EXPAREL adoption?
Reimbursement codes (CPT) facilitate adoption in hospitals, but variability in payer policies and pricing strategies continue to influence utilization levels.

4. What is the impact of patent expiry on EXPAREL's revenue?
Patent expiry (~2030) risks generic competition, potentially eroding premium pricing and market share unless new formulations or indications are developed.

5. What steps can Pacira take to sustain growth beyond patent expiration?
Investing in pipeline development, expanding into chronic pain indications, optimizing manufacturing, and entering new international markets are strategic options.
