fentanyl + lidocaine + bupivacaine + hyaluronidase

This drug is a multi-component local anesthetic mixture used for peribulbar block in ophthalmic surgeries, specifically anterior segment procedures. It combines two amide-type local anesthetics, **lidocaine** (fast-onset) and **bupivacaine** (long-acting), with **hyaluronidase**, an enzyme that acts as a spreading agent to enhance the dispersion of the anesthetics through the orbital tissues. **Fentanyl**, a potent synthetic opioid, is added as an adjuvant to enhance the quality of the block, provide supplemental analgesia, and potentially prolong the duration of postoperative pain relief. The mixture is typically administered via peribulbar injection to achieve akinesia and anesthesia of the eye.
