Common Brand Names; Zynrelef
NSAIDs Local Anesthetics, Parenteral
Description
Bupivacaine: Local amide anesthetic; blocks generation and conduction of nerve impulses presumably by increasing the electrical excitation threshold in the nerve, by slowing nerve impulse propagation, and by reducing the rate of action potential rise
Meloxicam: Member of oxicam class; inhibits synthesis of prostaglandins in body tissues by inhibiting at least 2 cyclooxygenase (COX) isoenzymes, COX-1 and COX-2
Indications
Postoperative Analgesia
Contraindications
Known hypersensitivity (eg, anaphylactic reactions, serious skin reactions) to any local anesthetic agent of the amide-type, NSAIDs, or to any of the other components
History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs; severe, sometimes fatal, anaphylactic reactions to NSAIDs reported
Patients undergoing obstetrical paracervical block anesthesia; use of bupivacaine in this technique has resulted in fetal bradycardia and death
Patients undergoing coronary artery bypass graft (CABG) surgery

Warnings
Bupivacaine
Prevent dose-related toxicity by assuring proper dose and correct technique
Limit exposure to articular cartilage due to the potential risk of chondrolysis
Chondrolysis reported with intra-articular infusion of local anesthetics; intra-articular infusions of local anesthetics, following arthroscopic and other surgical procedures is an unapproved use
Meloxicam
Anaphylaxis and aspirin-sensitive asthma
Cardiovascular events
Hypertension
GI bleeding, ulceration, and perforation
Pregnancy and Lactation
Pregnancy; Data are unavailable on use of bupivacaine/meloxicam in pregnant females to evaluate drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes; however, data are available on the individual components
Lactation: Data are unavailable on whether drug is present in human milk, or on the effects on breastfed infants, or on milk production
Maximum Dosage
Adults
Foot and ankle surgical procedures (eg, bunionectomy)
Up to 2.3 mL (bupivacaine 60 mg/meloxicam 1.8 mg); apply to proximal and distal ends (ie, beyond the boney repair) of the wound
Small-to-medium open abdominal procedures (open inguinal herniorrhaphy)
Up to 10.5 mL (bupivacaine 300 mg/meloxicam 9 mg); apply above and below the fascial repair
Lower extremity total joint arthroplasty surgical procedures (eg, total knee arthroplasty)
Up to 14 mL (bupivacaine 400 mg/meloxicam 12 mg); apply directly to posterior capsule, the anteromedial tissues and periosteum, and the anterolateral tissues and periosteum after cementation of the components
