Dosing: Adult
Reversal of nondepolarizing neuromuscular blocking agents

Reversal of nondepolarizing neuromuscular-blocking agents:

Note: Product formulation (Prevduo) contains neostigmine 1 mg and glycopyrrolate 0.2 mg per mL; dosing based on neostigmine component. Avoid use or use with caution in patients with certain neuromuscular diseases (eg, myasthenia gravis, muscular dystrophy); other agents may be preferred (eg, sugammadex); if neostigmine is used, reduced dosing may be required with titration based on train-of-four (TOF) monitoring (Ref). TOF monitoring should be used to determine time of neostigmine initiation and need for additional doses. Dosing may vary depending on patient-specific factors (eg, depth of paralysis, type of neuromuscular-blocking agent [NMBA] used, type of anesthesia, organ dysfunction, age, acid-base status) (Ref). Refer to institutional protocols and policies.

Usual dose: IV: Neostigmine 0.03 to 0.07 mg/kg (and glycopyrrolate 0.006 to 0.014 mg/kg); generally achieves a TOF twitch ratio of 90% within 10 to 20 minutes of administration; maximum total dose: neostigmine 0.07 mg/kg or 5 mg (whichever is less).

Dose selection based on neuromuscular-blocking agents administered or train-of-four monitoring:

Neostigmine 0.03 mg/kg: IV: Neostigmine 0.03 mg/kg dose is recommended for reversal of NMBAs with shorter half-lives (eg, rocuronium); or when the first twitch response to the TOF stimulus is substantially >10% of baseline or when a second twitch is present.

Neostigmine 0.07 mg/kg: IV: Neostigmine 0.07 mg/kg dose is recommended for reversal of NMBAs with longer half-lives (eg, vecuronium, pancuronium), when the first twitch response is relatively weak (ie, not substantially >10% of baseline), or when rapid recovery is needed.

Dosing: Kidney Impairment: Adult

There are no dosage adjustments provided in manufacturer's labeling; elimination of glycopyrrolate is severely impaired in kidney failure and neostigmine half-life is prolonged in anephric patients; use with caution and closely monitor.

Dosing: Liver Impairment: Adult

There are no dosage adjustments provided in manufacturer's labeling; however, neostigmine and some neuromuscular-blocking agents are metabolized by the liver; use with caution and monitor closely.

Dosing: Older Adult

Refer to adult dosing; use with caution.

Dosing: Pediatric

(For additional information see "Neostigmine and glycopyrrolate: Pediatric drug information")

Note: Product formulation (Prevduo) contains neostigmine 1 mg and glycopyrrolate 0.2 mg per mL; dosing based on neostigmine component.

Reversal of nondepolarizing neuromuscular blockade after surgery

Reversal of nondepolarizing neuromuscular blockade after surgery:

Note: Peripheral nerve stimulation delivering train-of-four (TOF) stimulus must be used to determine time of neostigmine initiation, monitoring of recovery of neuromuscular function, and possible need for additional doses. Dose necessary varies with neuromuscular blockade being reversed.

Children ≥2 years and Adolescents:

Usual dose: IV: Neostigmine: 0.03 to 0.07 mg/kg and glycopyrrolate 0.006 to 0.014 mg/kg generally achieves a TOF twitch ratio of 90% within 10 to 20 minutes of administration; maximum total dose: Neostigmine: 0.07 mg/kg or 5 mg (whichever is less).

Dose selection guide: IV:

Neostigmine 0.03 mg/kg dose is recommended for reversal of neuromuscular blocking agents (NMBAs) with shorter half-lives (eg, rocuronium), when the first twitch response to the TOF stimulus is substantially >10% of baseline, or when a second twitch is present.

Neostigmine 0.07 mg/kg dose is recommended for reversal of NMBAs with longer half-lives (eg, vecuronium, pancuronium), when the first twitch response is relatively weak (ie, not substantially >10% of baseline), or rapid recovery is needed.

Dosing: Kidney Impairment: Pediatric

There are no dosage adjustments provided in manufacturer's labeling; elimination of glycopyrrolate is severely impaired in kidney failure and neostigmine half-life is prolonged in anephric patients; use with caution and closely monitor.

Dosing: Liver Impairment: Pediatric

There are no dosage adjustments provided in manufacturer's labeling; however, neostigmine is metabolized by the liver, use with caution and monitor closely.

Adverse Reactions

See individual agents.

Contraindications

Hypersensitivity to neostigmine methylsulfate, glycopyrrolate, or any component of the formulation; peritonitis or mechanical obstruction of the intestinal or urinary tract; glaucoma; obstructive uropathy (eg, bladder neck obstruction due to prostatic hypertrophy); obstructive disease of the GI tract (eg, achalasia, pyloroduodenal stenosis); paralytic ileus, intestinal atony of the elderly or debilitated patient; unstable cardiovascular status in acute hemorrhage; severe ulcerative colitis; toxic megacolon complicating ulcerative colitis; myasthenia gravis.

Warnings/Precautions

Concerns related to adverse effects:

• Cardiovascular effects: Bradycardia, hypotension, and dysrhythmias may occur with neostigmine use; risk may be increased in patients with certain cardiovascular conditions (eg, coronary artery disease, cardiac arrhythmias, recent acute coronary syndrome). Risk may also be increased in patients with myasthenia gravis.

• Cholinergic crisis: Overdosage may result in cholinergic crisis, characterized by extreme muscle weakness and potentially fatal respiratory paralysis. Cholinergic crisis should be distinguished from myasthenic crisis, which is also characterized by extreme muscle weakness, but would require radically different treatment.

• CNS effects: Glycopyrrolate may cause drowsiness and/or blurred vision, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery, driving).

• Heat prostration: Glycopyrrolate may cause heat prostration in the presence of fever, increased environmental temperature, and/or during physical exercise, particularly in children and older adults; use caution in hot weather and/or exercise. Avoid exertion and high environmental temperature after administration.

• Hypersensitivity reactions: Symptoms of hypersensitivity have included anaphylaxis, angioedema, bradycardia, bronchospasm, erythema multiforme, facial swelling, flushing, generalized rash, hypotension, peripheral edema, pyrexia, and urticaria. Have epinephrine and atropine ready to treat hypersensitivity reactions.

• Intestinal obstruction (incomplete): Diarrhea may be an early sign of incomplete intestinal obstruction, especially in patients with an ileostomy or colostomy; avoid use in these patients.

• Neuromuscular effects: Large doses of IV neostigmine administered for the reversal of nondepolarizing neuromuscular-blocking agents, when neuromuscular blockade is minimal, can result in neuromuscular dysfunction. Reduce dose if recovery from neuromuscular blockade is nearly complete.

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with bradycardia, cardiac arrhythmias, coronary artery disease, heart failure, hypertension, recent acute coronary syndrome, or tachycardia; evaluate tachycardia before administration.

• Hyperthyroidism: Use with caution in patients with hyperthyroidism.

• Kidney impairment: Use with caution in patients with kidney impairment; elimination of glycopyrrolate is severely impaired in kidney failure and neostigmine half-life is prolonged in anephric patients.

• Neuromuscular diseases: For reversal of nondepolarizing neuromuscular blockade, avoid use or use with caution in patients with certain neuromuscular diseases (eg, myasthenia gravis, muscular dystrophy); other agents may be preferred (eg, sugammadex); if used, reduced dosing may be required with titration based on train-of-four monitoring (Balaka 2011; Briggs 2003; Buzello 1982). Adequate facilities should be available for cardiopulmonary resuscitation when testing and adjusting dose for myasthenia gravis.

• Vagotonia: Use with caution in patients with vagotonia.

Special populations:

• Older adult: Use with caution and monitor for a longer period.
