Introduction
Opiate partial agonist; phenanthrene derivative.a b d
Uses for Butorphanol Tartrate
Pain
Relief of moderate to severe pain such as that associated with acute and chronic medical disorders including cancer, neuropathic or spastic conditions, orthopedic problems, burns, renal colic, and surgery.d
Preoperative sedation and analgesia and as a supplement to surgical anesthesia.a
Obstetric analgesia during labor.a
Management of pain associated with migraine headache.113 114 116 122
In equianalgesic doses, parenteral butorphanol is as effective as morphine, meperidine, and pentazocine, but relative potential for abuse reportedly is less than that of codeine or propoxyphene.d
Butorphanol Tartrate Dosage and Administration
Administration
Administer IM, by IV injection, or by nasal inhalation.113
Nasal Administration
Assemble the nasal solution spray pump according to the manufacturer’s instructions.113 Prior to initial use, fully prime the spray pump; reprime pump whenever it has not been used for ≥48 hours.113
Consult the manufacturer’s patient instructions regarding use of the nasal solution spray pump.113 124
The nasal solution spray pump is an open delivery system; aim the pump spray away from the patient, other individuals, or animals to minimize environmental exposure.113
IV Administration
For drug compatibility information, see Compatibility under Stability.
Dosage
Available as butorphanol tartrate; dosage expressed in terms of the salt.a b
After initial priming, the nasal solution spray pump delivers about 14–15 metered doses containing 1 mg per spray.a If repriming of the pump is necessary, the spray pump will deliver about 8–10 metered doses, depending on the extent of repriming.113
Adults
Pain
IV
Initially, 1 mg; may repeat dose every 3–4 hours as necessary.a Usual effective dosage, depending on severity of pain, is 0.5–2 mg repeated every 3–4 hours.a
IM
Initially, 2 mg in patients able to remain recumbent; may repeat dose every 3–4 hours as necessary.a Usual effective dosage, depending on severity of pain, is 1–4 mg repeated every 3–4 hours.a
Intranasal
Initially, 1 mg (1 spray in 1 nostril); if adequate analgesia is not achieved, may give an additional 1-mg dose within 60–90 minutes.113 May repeat this initial dose sequence in 3–4 hours, if needed.113
For management of severe pain: Initially, 2 mg (1 spray in each nostril) in patients who can remain recumbent if drowsiness or dizziness occurs.113 Do not administer additional 2-mg doses at intervals <3–4 hours, since the incidence of adverse effects may be increased.113
Preoperative Sedation and Analgesia
IM
Usual dosage is 2 mg administered 60–90 minutes before surgery.a
Supplement to Surgical Anesthesia
IV
2 mg shortly before induction of anesthesia and/or 0.5–1 mg administered during anesthesia in increments up to 0.06 mg/kg (depending on previous administration of sedatives, analgesics, and hypnotic agents).a Usual total dose is 4–12.5 mg (approximately 0.06–0.18 mg/kg).a

Cautions for Butorphanol Tartrate
Contraindications
Warnings/Precautions
Warnings
Abuse Potential
Possible tolerance, psychologic dependence, and physical dependence.a b d Episodes of abuse associated with all routes of administration, especially nasal administration.a b
Patients with a history of drug or alcohol dependence or abuse are at risk of habituation or dependence; use only with careful surveillance in such patients.a b
Patients Dependent on Opiates
Partial opiate antagonist; not recommended for use in patients physically dependent on opiatesa because of the potential to precipitate symptoms of withdrawal (e.g., anxiety, agitation, mood changes, hallucinations, dysphoria, weakness, diarrhea).128 129
Use with caution in patients who recently received repeated doses of opiate analgesics; allow an adequate period of withdrawal from opiates before initiation of butorphanol therapy.128 129
General Precautions
Head Injury and Increased Intracranial Pressure
Adverse effects of opiates may obscure the existence, extent, or course of intracranial pathology.113 Use in patients with head injury only if the potential benefits justify the possible risks.113
Respiratory Effects
Possible respiratory depression, especially in patients with impaired respiration caused by other drugs, uremia, severe infection, severely limited respiratory reserve, bronchial asthma, respiratory obstruction, or cyanosis.a b d Use with caution and in lower dosages in these patients.a b d
Cardiovascular Effects
Possible increased myocardial workload; use in patients with AMI, ventricular dysfunction, or coronary insufficiency only if the potential benefits justify the possible risks.a b
Severe hypertension reported rarely.a b If hypertension occurs, discontinue and administer a hypotensive agent as necessary; butorphanol-induced hypertension reportedly has been managed with naloxone in patients who were not opiate dependent.113
Use cautiously before surgery or anesthesia in hypertensive patients.d
Possible hypotension associated with syncope in patients receiving nasal solution; caution patients against performing activities that may pose risks if hypotension were to occur.113
CNS Depression
Performance of activities requiring mental alertness and physical coordination may be impaired.a b
Concurrent use of other CNS depressants may potentiate CNS depression.a b (See Specific Drugs under Interactions.)
Biliary Tract Surgery
Safe use in patients about to undergo biliary tract surgery has not been established; use with caution.d
Specific Populations
Pregnancy
Category C.a b
Use of intranasal spray not recommended during labor and delivery.

Butorphanol Tartrate Pharmacokinetics
Absorption
Bioavailability
Rapidly absorbed following IM injection; peak plasma concentrations usually attained within 30–60 minutes.a d
Following nasal inhalation, peak blood concentrations are achieved in about 30–60 minutes.113 114 Absolute bioavailability of nasally administered butorphanol is 60–70% and appears to be unchanged in patients with allergic rhinitis.a
Completely absorbed from the GI tract following oral administration; however, after first-pass metabolism, bioavilability is only 5–17%.a b
Onset
Onset of analgesic activity occurs in a few minutes after IV administration or within 15 minutes after IM administration;a b peak analgesic effect achieved within 30–60 minutes after IV or IM administration.a
After nasal inhalation in postoperative patients, onset of analgesia occurs within 15 minutes;113 114 125 peak analgesic effect achieved within 1–2 hours.b
Duration
After IV or IM administration, duration of analgesia is 3–4 hours.a b
After nasal inhalation in postoperative patients, duration of analgesia is approximately 2.5–5 hours.113 114 125
Distribution
Extent
Highest concentrations of butorphanol and its metabolites in animals are found in the liver, kidneys, and intestine; drug concentrations are higher in the lungs, spleen, heart, endocrine tissues, blood cells, and fat tissue than in plasma; brain concentrations are lower than plasma concentrations.d
Rapidly crosses the placenta and is distributed into milk.a b
Plasma Protein Binding
About 80%.a b
Elimination
Metabolism
Extensively metabolized in the liver, principally by hydroxylation; N-dealkylation and conjugation of butorphanol and its metabolites also occur.a b d Metabolites have no analgesic activity.d
Elimination Route
Excreted prinicipally in urine (70–80%) mainly as metabolites; also excreted in feces (15%).a b
Half-life
About 4.6–4.7 hours following intranasal or IV administration.113 114
Special Populations
In patients with hepatic impairment, elimination half-life of 16.8 hours reported.b
In patients with renal impairment (Clcr <30 mL/minute), elimination half-life of 10.5 hours reported.113
In geriatric individuals, elimination half-life reported to be about 5.6 hours (range 3.3–8.8 hours) or 6.6 hours (range: 3.8–9.2 hours) following IV or intranasal administration, respectively.113

ActionsActions
Analgesic effect is believed to result from an interaction with an opiate receptor site in the CNS (probably in or associated with the limbic system).a
Opiate antagonistic effect may result from competitive inhibition at the opiate receptor, but other mechanisms probably also are involved.d Butorphanol exerts antagonistic114 115 126 or partially antagonistic113 effects at μ opiate receptor sites; it appears to exerts agonistic effects principally at κ and Σ opiate receptors.101 102 103 104
Produces respiratory depression, sedation, miosis and, in animals, antitussive effect.a
Slightly increases pulmonary artery pressure, pulmonary wedge pressure, left ventricular end-diastolic pressure, systemic arterial pressure, pulmonary vascular resistance, and cardiac index.a
In animals, inhibits GI motility slightly, causes little increase in duodenal smooth muscle activity, and has little or no effect on bile duct flow.d
Advice to Patients
Potential for butorphanol to impair mental alertness or physical coordination; do not drive or operate machinery for ≥1 hour after receiving the drug or until effects on individual are known.a b
Patients receiving the nasal solution should not perform activities that may pose risks if hypotension were to occur.113
Importance of taking only as prescribed; do not increase dosage or duration of therapy unless otherwise instructed by a clinician.a b
Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and alcohol consumption.a b Importance of avoiding alcohol while receiving the drug.a b
Importance of women informing their clinician if they are or plan to become pregnant or to breast-feed.a b
Importance of advising patients of other important precautionary information.a b (See Cautions.)
