Mechanism of Action

Local anesthetics block the generation and the conduction of nerve impulses presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse, and by reducing the rate of rise of the action potential.

Exparel Indications

Indications

For infiltration to produce postsurgical local analgesia in patients aged ≥6yrs. To produce postsurgical regional analgesia in adults via: an interscalene brachial plexus nerve block; a sciatic nerve block in the popliteal fossa; or an adductor canal block.

Limitations of Use

Safety and efficacy have not been established in other nerve blocks.

Exparel Dosage and Administration

Adults and Children

<6yrs for infiltration and <18yrs for regional nerve block: not recommended. For single-dose administration only. Inject slowly (usually 1–2mL per inj); perform frequent aspiration to check for blood. Local infiltration (6–17yrs): 4mg/kg; (≥18yrs; base dose on surgical site and volume required to cover area): up to max 266mg (20mL); bunionectomy: 106mg (8mL); hemorrhoidectomy: 266mg (20mL). Regional nerve block (≥18yrs): max 133mg (10mL). See full labeling for administration, others.

Exparel Interactions

Interactions

Do not dilute with water or hypotonic agents (may result in disruption of liposomal particles). Do not mix with lidocaine or other non-bupivacaine-based local anesthetics. Avoid additional local anesthetics within 96hrs following administration of Exparel. May administer after at least 20mins following local administration of lidocaine. Bupivacaine HCl, when injected immediately before or admixed with Exparel, may impact the pharmacokinetic and/or physicochemical properties of the drugs; may be admixed simultaneously or inject bupivacaine HCl immediately before Exparel as long as the mg dose ratio of bupivacaine HCl to Exparel does not exceed 1:2. Avoid contact with antiseptics (eg, povidone iodine). Increased risk of methemoglobinemia with concomitant other local anesthetics, acetaminophen, sulfonamides, nitrates, phenytoin, phenobarbital; see full labeling.
