            Warnings

            Contraindications

            Hypersensitivity to aminobenzoic acid, sulfites, parabens, or any components of preparation

            Spinal anesthesia

            Cautions

            Use preservative-free preparations for spinal or epidural anesthesia

            Some formulations may contain sulfites

            Use caution in decreased levels of plasma esterases, hyperthyroidism, cardiovascular disease (heart block, rhythm disturbances, shock)

            Use caution in the elderly, debilitated patients, obstetrics, or patients with intraabdominal pressure

            DO NOT use solutions with epinephrine in distal areas of body (eg, digit, nose, ear, etc)

            Addition of vasoconstrictor, epinephrine, will promote local hemostasis, decrease systemic absorption, and increase duration of action

            Pregnancy & Lactation

            Pregnancy Category: C

            Lactation: Not known if excreted in breast milk; use caution

            Pregnancy Categories

            A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA:Information not available.

            Pharmacology

            Mechanism of Action

            Local anesthetics prevent generation/conduction of nerve impulses by reducing sodium permeability & increasing action potential threshold

            Pharmacokinetics

            Duration: the greater the degree of vasodilation produced by the local anesthetic, the faster the rate of absorption and shorter the duration of action (bupivacaine has a long duration of action)

            Protein Bound: Highly

            Metabolism: Liver

            Metabolites: Ester- & amide-type local anesthetics

            Excretion: Urine (principally)
