Indication For the management of pain when the use of an opioid analgesic is appropriate. Also indicated as a preoperative or preanesthetic medication, as a supplement to balanced anesthesia, and for the relief of pain during labor.
Pharmacology Butorphanol is a synthetic opioid agonist-antagonist analgesic with a pharmacological and therapeutic profile that has been well established since its launch as a parenteral formulation in 1978. The introduction of a transnasal formulation of butorphanol represents a new and noninvasive presentation of an analgesic for moderate to severe pain. This route of administration bypasses the gastrointestinal tract, and this is an advantage for a drug such as butorphanol that undergoes significant first-pass metabolism after oral administration. The onset of action and systemic bioavailability of butorphanol following transnasal delivery are similar to those after parenteral administration. Butorphanol blocks pain impulses at specific sites in the brain and spinal cord.
Mechanism of Action Butorphanol is a mixed agonist-antagonist with low intrinsic activity at receptors of the µ-opioid type (morphine-like). It is also an agonist at κ-opioid receptors. Its interactions with these receptors in the central nervous system apparently mediate most of its pharmacologic effects, including analgesia.
Absorption Rapidly absorbed after intramuscular injection and peak plasma levels are reached in 20-40 minutes. The absolute bioavailability is 60-70% and is unchanged in patients with allergic rhinitis. In patients using a nasal vasoconstrictor (oxymetazoline) the fraction of the dose absorbed was unchanged, but the rate of absorption was slowed. Oral bioavailability is only 5-17% because of extensive first-pass metabolism.
Toxicity The clinical manifestations of butorphanol overdose are those of opioid drugs in general. The most serious symptoms are hypoventilation, cardiovascular insufficiency, coma, and death.
Protein Binding Serum protein binding is approximately 80%.
Biotransformation Extensively metabolized in the liver. The pharmacological activity of butorphanol metabolites has not been studied in humans; in animal studies, butorphanol metabolites have demonstrated some analgesic activity.
Half Life The elimination half-life of butorphanol is about 18 hours. In renally impaired patients with creatinine clearances <30 mL/min the elimination half-life is approximately doubled. After intravenous administration to patients with hepatic impairment, the elimination half-life of butorphanol was approximately tripled.
