ropivacaine or levobupivacaine

This term is **non-specific**: it denotes an alternative choice between **ropivacaine** and **levobupivacaine**, two distinct long-acting amino-amide local anesthetic drugs, rather than a single molecular entity or a co-formulated combination. Both reversibly inhibit voltage-gated sodium channels in peripheral nerves, preventing action-potential initiation and propagation to produce regional anesthesia and analgesia. In the provided rotator-cuff-repair study, either agent may be used for loco-regional anesthesia. Ropivacaine injection is indicated for local or regional anesthesia and acute pain management.
