Uses

1 INDICATIONS AND USAGE BRIDION ® is indicated for the reversal of neuromuscular blockade induced by rocuronium bromide and vecuronium bromide in adult and pediatric patients undergoing surgery. BRIDION is indicated for the reversal of neuromuscular blockade induced by rocuronium bromide and vecuronium bromide in adult and pediatric patients undergoing surgery. ( 1 )

Dosage and administration

Dosing is based on actual body weight ( 2.1 ) Monitor for twitch responses to determine the timing and dose for BRIDION administration. ( 2.1 ) Administer as a single bolus injection. ( 2.1 ) For rocuronium and vecuronium: 4 mg/kg is recommended if spontaneous recovery of the twitch response has reached 1 to 2 post-tetanic counts (PTC) and there are no twitch responses to train-of-four (TOF) stimulation. ( 2.2 ) 2 mg/kg is recommended if spontaneous recovery has reached the reappearance of the second twitch in response to TOF stimulation. ( 2.2 ) For rocuronium only: 16 mg/kg is recommended if there is a clinical need to reverse neuromuscular blockade soon (approximately 3 minutes) after administration of a single dose of 1.2 mg/kg of rocuronium. Immediate reversal in pediatric patients has not been studied. ( 2.2 ) 2.1 Important Dosing and Administration Information BRIDION dosing is based on actual body weight. BRIDION (sugammadex) injection, for intravenous use, should be administered by trained healthcare providers familiar with the use, actions, characteristics, and complications of neuromuscular blocking agents (NMBA) and neuromuscular block reversal agents. Doses and timing of BRIDION administration should be based on monitoring for twitch responses and the extent of spontaneous recovery that has occurred. Administer BRIDION intravenously as a single bolus injection. The bolus injection may be given over 10 seconds, into an existing intravenous line. BRIDION has only been administered as a single bolus injection in clinical trials. From the time of BRIDION administration until complete recovery of neuromuscular function, monitor the patient to assure adequate ventilation and maintenance of a patent airway. Satisfactory recovery should be determined through assessment of skeletal muscle tone and respiratory measurements in addition to the response to peripheral nerve stimulation. The recommended dose of BRIDION does not depend on the anesthetic regimen. Preparation of dilution for pediatric use: BRIDION 100 mg/mL may be diluted to a concentration of 10 mg/mL, using 0.9% sodium chloride injection, USP, to increase the accuracy of dosing in the pediatric population. To prepare the required dose, aseptically transfer all the contents of the 2 mL vial of BRIDION 2-mL single-dose vials containing 200 mg sugammadex (100 mg/mL) to a bottle (or intravenous bag) containing 18 mL of 0.9% sodium chloride injection, to achieve a final concentration of 10 mg/mL sugammadex. The diluted solution should be used immediately. BRIDION injection is a single-dose sterile solution without preservatives. Discard any unused portion from the vial. 2.2 Recommended Dosing BRIDION can be used to reverse different levels of rocuronium- or vecuronium-induced neuromuscular blockade. For rocuronium and vecuronium: A dose of 4 mg/kg BRIDION is recommended if spontaneous recovery of the twitch response has reached 1 to 2 post-tetanic counts (PTC) and there are no twitch responses to train-of-four (TOF) stimulation following rocuronium- or vecuronium-induced neuromuscular blockade [see Warnings and Precautions (5.8) ]. A dose of 2 mg/kg BRIDION is recommended if spontaneous recovery has reached the reappearance of the second twitch (T 2 ) in response to TOF stimulation following rocuronium- or vecuronium-induced neuromuscular blockade [see Warnings and Precautions (5.8) ]. For rocuronium only: A dose of 16 mg/kg BRIDION is recommended if there is a clinical need to reverse neuromuscular blockade soon (approximately 3 minutes) after administration of a single dose of 1.2 mg/kg of rocuronium. The efficacy of the 16 mg/kg dose of BRIDION following administration of vecuronium has not been studied. Immediate reversal in pediatric patients has not been studied [see Clinical Studies (14.1) ]. 2.3 Drug Compatibility May inject BRIDION into the intravenous line of a running infusion with the following intravenous solutions: 0.9% sodium chloride 5% dextrose 0.45% sodium chloride and 2.5% dextrose 5% dextrose in 0.9% sodium chloride isolyte P with 5% dextrose Ringer's lactate solution Ringer's solution Ensure the infusion line is adequately flushed (e.g., with 0.9% sodium chloride) between administration of BRIDION and other drugs. Do not mix BRIDION with other products except those listed above. BRIDION is physically incompatible with verapamil, ondansetron, and ranitidine. Visually inspect parenteral drug products for particulate matter and discoloration prior to administration, whenever the solution and container permit.

Dosage forms and strengths

Contraindications

4 CONTRAINDICATIONS BRIDION is contraindicated in patients with known hypersensitivity to sugammadex or any of its components. Hypersensitivity reactions that occurred varied from isolated skin reactions to serious systemic reactions (i.e., anaphylaxis, anaphylactic shock) and have occurred in patients with no prior exposure to sugammadex [see Warnings and Precautions (5.1) , Adverse Reactions (6) ] . Known hypersensitivity to sugammadex or any of its components. ( 4 )

Warnings and precautions

Anaphylaxis : Be prepared for hypersensitivity reactions (including anaphylactic reactions) and take necessary precautions. ( 5.1 ) Marked Bradycardia : Cases of marked bradycardia, some of which have resulted in cardiac arrest, have been observed within minutes after administration. Monitor for hemodynamic changes and administer anticholinergic agents such as atropine if clinically significant bradycardia is observed. ( 5.2 ) Respiratory Function Monitoring : Ventilatory support is mandatory until adequate spontaneous respiration is restored and the ability to maintain a patent airway is assured. Provide adequate ventilation if neuromuscular blockade persists after BRIDION or recurs following extubation. ( 5.3 , 5.4 ) Waiting Times for Re-Administration of Neuromuscular Blocking Agents : If re-administration of a neuromuscular blocking agent is required after reversal with BRIDION, waiting times should be based on the dose of BRIDION and the renal function of the patient. Consider use of a nonsteroidal neuromuscular blocking agent. ( 5.5 ) 5.1 Anaphylaxis and Hypersensitivity Clinicians should be prepared for the possibility of drug hypersensitivity reactions (including anaphylactic reactions) and take the necessary precautions [see Contraindications (4) , Adverse Reactions (6.1) ] . Potentially serious hypersensitivity reactions, including anaphylaxis, have occurred in patients treated with BRIDION. The nature and frequency of anaphylaxis and hypersensitivity associated with BRIDION administration were evaluated in a randomized, double-blind, placebo-controlled, parallel-group, repeat-dose study in which 375 subjects were randomized to receive 3 doses of BRIDION IV with a 5-week washout period: 151 subjects received 4 mg/kg, 148 received 16 mg/kg and 76 received placebo. The frequency of anaphylaxis for the 299 healthy volunteers treated with intravenous BRIDION was 0.3% (n=1 in the BRIDION 16 mg/kg group on the first dose). Signs and symptoms included conjunctival edema, urticaria, erythema, swelling of the uvula and reduction in peak expiratory flow within 5 minutes of dose administration. The most common hypersensitivity adverse reactions reported were nausea, pruritus and urticaria and showed a dose response relationship, occurring more frequently in the 16 mg/kg group compared to the 4 mg/kg and placebo groups. Anaphylaxis has also been reported in the post-marketing setting, including at doses less than 16 mg/kg. The most commonly described clinical features in reports of anaphylaxis were dermatologic symptoms (including urticaria, rash, erythema, flushing and skin eruption); and clinically important hypotension often requiring the use of vasopressors for circulatory support. In addition, prolonged hospitalization and/or the use of additional respiratory support until full recovery (re-intubation, prolonged intubation, manual or mechanical ventilation) have been noted in a number of the anaphylaxis reports. 5.2 Marked Bradycardia Cases of marked bradycardia, some of which have resulted in cardiac arrest, have been observed within minutes after the administration of BRIDION [see Adverse Reactions (6.2) ] . Patients should be closely monitored for hemodynamic changes during and after reversal of neuromuscular blockade. Treatment with anticholinergic agents, such as atropine, should be administered if clinically significant bradycardia is observed. 5.3 Respiratory Function Monitoring During Recovery Ventilatory support is mandatory for patients until adequate spontaneous respiration is restored and the ability to maintain a patent airway is assured. Even if recovery from neuromuscular blockade is complete, other drugs used in the peri- and post-operative period could depress respiratory function and therefore ventilatory support might still be required. Should neuromuscular blockade persist after BRIDION administration or recur following extubation, take appropriate steps to provide adequate ventilation. 5.4 Risk of Prolonged Neuromuscular Blockade In clinical trials, a small number of patients experienced a delayed or minimal response to the administration of BRIDION [see Clinical Studies (14.1) ] . Thus, it is important to monitor ventilation until recovery occurs. 5.5 Waiting Times for Re-Administration of Neuromuscular Blocking Agents for Intubation Following Reversal with BRIDION A minimum waiting time is necessary before administration of a steroidal neuromuscular blocking agent after administration of BRIDION. Table 1: Re-administration of Rocuronium or Vecuronium after Reversal (up to 4 mg/kg BRIDION) Minimum Waiting Time NMBA and Dose to be Administered 5 minutes 1.2 mg/kg rocuronium 4 hours 0.6 mg/kg rocuronium or 0.1 mg/kg vecuronium When rocuronium 1.2 mg/kg is administered within 30 minutes after reversal with BRIDION, the onset of neuromuscular blockade may be delayed up to approximately 4 minutes and the duration of neuromuscular blockade may be shortened up to approximately 15 minutes. The recommended waiting time in patients with mild or moderate renal impairment for re-use of 0.6 mg/kg rocuronium or 0.1 mg/kg vecuronium after reversal with up to 4 mg/kg BRIDION should be 24 hours. If a shorter waiting time is required, the rocuronium dose for a new neuromuscular blockade should be 1.2 mg/kg. For re-administration of rocuronium or administration of vecuronium after reversal of rocuronium with 16 mg/kg BRIDION, a waiting time of 24 hours is suggested. If neuromuscular blockade is required before the recommended waiting time has elapsed, use a nonsteroidal neuromuscular blocking agent . The onset of a depolarizing neuromuscular blocking agent might be slower than expected, because a substantial fraction of postjunctional nicotinic receptors can still be occupied by the neuromuscular blocking agent.

Side effects

The following serious adverse reactions are described elsewhere in the labeling: Anaphylaxis and Hypersensitivity [see Contraindications (4) , Warnings and Precautions (5.1) ] Marked Bradycardia [see Warnings and Precautions (5.2) ] Most common adverse reactions (reported in ≥10% of adult patients at a 2, 4, or 16 mg/kg BRIDION dose and higher than the placebo rate): vomiting, pain, nausea, hypotension, and headache. ( 6.1 ) Most common adverse reactions (reported in ≥10% of pediatric patients 2 to <17 years of age at BRIDION doses of 2 or 4 mg/kg) were pain, vomiting, and nausea. ( 6.1 ) Most common adverse reaction (reported in ≥10% of pediatric patients from birth to <2 years of age at BRIDION doses of 2 or 4 mg/kg) was procedural pain.

Adult Patients The data described below reflect 2914 subjects exposed to 2, 4, or 16 mg/kg BRIDION and 544 to placebo in pooled Phase 1-3 studies. The population was 18 to 92 years old, 47% male and 53% female, 34% ASA (American Society of Anesthesiologists) Class 1, 51% ASA Class 2, and 14% ASA Class 3, and 82% Caucasian. Most subjects received a single dose of BRIDION 2 mg/kg or 4 mg/kg. Adverse reactions reported in ≥10% of patients at a 2, 4, or 16 mg/kg BRIDION dose with a rate higher than the placebo rate are: vomiting, pain, nausea, hypotension, and headache. All adverse reactions occurring in ≥2% of subjects treated with BRIDION and more often than placebo for adult subjects who received anesthesia and/or neuromuscular blocking agent in pooled Phase 1 to 3 studies are presented in Table 2.

Drug interactions

Toremifene : Concomitant use can delay recovery. ( 7.2 ) Hormonal contraceptives : Patients must use an additional, non-hormonal method of contraception for 7 days following BRIDION administration. ( 5.6 , 7.3 ) 7.1 Summary The information reported in sections 7.2 – 7.4 is based on binding affinity between BRIDION and other drugs, preclinical experiments, clinical studies and simulations of a pharmacokinetic-pharmacodynamic (PK-PD) model. Based on these considerations, no clinically significant pharmacodynamic interactions with other drugs are expected, with the exception of toremifene and hormonal contraceptives. 7.2 Interactions Potentially Affecting the Efficacy of BRIDION Toremifene For toremifene, which has a relatively high binding affinity for sugammadex and for which relatively high plasma concentrations might be present, some displacement of vecuronium or rocuronium from the complex with BRIDION could occur. The recovery to TOF ratio to 0.9 could therefore be delayed in patients who have received toremifene on the same day of surgery. 7.3 Interaction Potentially Affecting the Efficacy of Hormonal Contraceptives In vitro binding studies indicate that BRIDION may bind to progestogen, thereby decreasing progestogen exposure. Therefore, the administration of a bolus dose of BRIDION is considered to be equivalent to missing dose(s) of oral contraceptives containing an estrogen or progestogen. If an oral contraceptive is taken on the same day that BRIDION is administered, the patient must use an additional, non-hormonal contraceptive method or back-up method of contraception (such as condoms and spermicides) for the next 7 days. In the case of non-oral hormonal contraceptives, the patient must use an additional, non-hormonal contraceptive method or back-up method of contraception (such as condoms and spermicides) for the next 7 days. 7.4 Interference with Laboratory Tests BRIDION may interfere with the serum progesterone assay. Interference with this test was observed at sugammadex plasma concentrations of 100 mcg/mL, which may be observed for up to 30 minutes after a 16 mg/kg dose.

Use in specific populations

Severe Renal Impairment : Not recommended. ( 8.6 ) 8.1 Pregnancy Risk Summary There are no clinical trial data on BRIDION use in pregnant women to inform any drug-associated risks. The available data from the pharmacovigilance safety database and published literature on BRIDION use in pregnant women are insufficient to identify a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, there was no evidence of malformations following daily intravenous administration of sugammadex to rats and rabbits during organogenesis at exposures of up to 6 and 8 times, respectively, the maximum recommended human dose (MRHD) of 16 mg/kg. However, there was an increase in the incidence of incomplete ossification of the sternebra and reduced fetal body weights in the rabbit study at 8 times the MRHD, which is a dose level in which maternal toxicity was also observed. In a pre- and postnatal development study, sugammadex treatment resulted in an increase in early postnatal loss, which correlated with maternal behavior (increased incidence of pup cannibalism), at exposures equivalent to the MRHD and higher (see Data ) . The background risk of major birth defects and miscarriage for the indicated population are unknown. However, the background risk in the U.S. general population of major birth defects is 2-4% and of miscarriage is 15-20% of clinically recognized pregnancies. Data Animal Data In an embryofetal development study in rats, pregnant animals received daily intravenous administration of sugammadex at 0, 20, 100, and 500 mg/kg (0.2, 1, and 6 times the MRHD of 16 mg/kg/day, respectively, based on AUC comparison) during organogenesis (Gestational Days 6-17). No treatment-related maternal and embryofetal changes were observed. In another embryofetal development study, pregnant New Zealand white rabbits received daily intravenous administration of sugammadex at 0, 20, 65, 200 mg/kg (0.6, 2, and 8 times the MRHD, respectively, based on AUC comparison) during organogenesis (Gestational Days 6-18). Fetal body weight decreases (10 and 14%, respectively) were observed in the offspring at maternal doses of 65 mg/kg and 200 mg/kg. In addition, incomplete ossification of sternebra, and unossified 1st metacarpal were noted at a maternal dose of 200 mg/kg/day. Maternal toxicity was also observed at 200 mg/kg. Considering the observed effects of sugammadex on bone [see Nonclinical Toxicology (13.2) ] , it is possible that these findings may be attributable to drug. There was no evidence of malformations at any dose. In a prenatal and postnatal development study, pregnant rats were administered sugammadex intravenously at 0, 30, 120, and 500 mg/kg (0.3, 1, and 6 times the MRHD, respectively, based on AUC comparison) from Gestational Day (GD) 6 to Postnatal Day (PND) 21 (corresponding to the beginning of organogenesis through parturition and subsequent pup weaning). Postnatal loss during PND 1-4 was noted across control litters and treated litters from dams receiving sugammadex as a result of pup cannibalization by dams. Overall incidence of affected litters was 2, 1, 4, and 3 litters, respectively, at 0, 30, 120, or 500 mg/kg/day. The reason for the increased cannibalization is not known. An effect of sugammadex on steroidal hormones and/or pheromones cannot be ruled out. In addition, there were no drug-related effects on parturition in rats during evaluations for prenatal or postnatal development. 8.2 Lactation Risk Summary No data are available regarding the presence of sugammadex in human milk, the effects of sugammadex on the breast fed infant, or the effects of sugammadex on milk production. However, sugammadex is present in rat milk (see Data ) . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for BRIDION and any potential adverse effects on the breastfed infant from BRIDION or from the underlying maternal condition. Data In a milk excretion study in rat dams following single intravenous dose of 20 mg/kg sugammadex on Postnatal Day 9, the maximum drug level was achieved at about 30 minutes after dosing with a ratio of milk to plasma level approximately 1:1. The oral exposure via milk did not induce effects on survival, body weight and physical or the behavioral developmental parameters monitored in rats in the prenatal and postnatal development studies [see Use in Specific Populations (8.1) ] . 8.3 Females and Males of Reproductive Potential Contraception Upon administration of BRIDION, the efficacy of hormonal contraceptives may be reduced for up to 7 days. Advise female patients of reproductive potential using hormonal contraceptives to use an additional, non-hormonal contraceptive for the next 7 days following BRIDION administration [see Drug Interactions (7.3) ] . 8.4 Pediatric Use The safety and effectiveness of BRIDION for reversal of neuromuscular blockade induced by rocuronium bromide or vecuronium bromide have been established in pediatric patients from birth and older. Use of BRIDION in these age groups is supported by evidence from adequate and well-controlled studies of BRIDION [see Clinical Pharmacology (12.3) and Clinical Studies (14.1) ]. In pediatric patients, the safety profile is generally consistent with that observed in adults [see Adverse Reactions (6.1) ] . Juvenile Animal Studies In a bone deposition study, sugammadex concentrations were significantly higher in juvenile rats compared to adult rats (13% vs. 3% of the administered dose, respectively) following a single intravenous (IV) dose at 30 mg/kg (0.3 times the MRHD based on adult AUC comparison). In a juvenile animal bone toxicity study, 7-day old rats were dosed intravenously once daily for 28 days with 0, 30, 120, and 500 mg/kg sugammadex (approximately 0.1, 0.6, and 3 times the MRHD, respectively, by adult AUC comparison).

Pregnancy

8.1 Pregnancy Risk Summary There are no clinical trial data on BRIDION use in pregnant women to inform any drug-associated risks. The available data from the pharmacovigilance safety database and published literature on BRIDION use in pregnant women are insufficient to identify a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.

Data Animal Data In an embryofetal development study in rats, pregnant animals received daily intravenous administration of sugammadex at 0, 20, 100, and 500 mg/kg (0.2, 1, and 6 times the MRHD of 16 mg/kg/day, respectively, based on AUC comparison) during organogenesis (Gestational Days 6-17). No treatment-related maternal and embryofetal changes were observed. In another embryofetal development study, pregnant New Zealand white rabbits received daily intravenous administration of sugammadex at 0, 20, 65, 200 mg/kg (0.6, 2, and 8 times the MRHD, respectively, based on AUC comparison) during organogenesis (Gestational Days 6-18).

Postnatal loss during PND 1-4 was noted across control litters and treated litters from dams receiving sugammadex as a result of pup cannibalization by dams. Overall incidence of affected litters was 2, 1, 4, and 3 litters, respectively, at 0, 30, 120, or 500 mg/kg/day. The reason for the increased cannibalization is not known. An effect of sugammadex on steroidal hormones and/or pheromones cannot be ruled out. In addition, there were no drug-related effects on parturition in rats during evaluations for prenatal or postnatal development.

Pediatric use

8.4 Pediatric Use The safety and effectiveness of BRIDION for reversal of neuromuscular blockade induced by rocuronium bromide or vecuronium bromide have been established in pediatric patients from birth and older. Use of BRIDION in these age groups is supported by evidence from adequate and well-controlled studies of BRIDION [see Clinical Pharmacology (12.3) and Clinical Studies (14.1) ]. In pediatric patients, the safety profile is generally consistent with that observed in adults [see Adverse Reactions (6.1) ] . Juvenile Animal Studies In a bone deposition study, sugammadex concentrations were significantly higher in juvenile rats compared to adult rats (13% vs. 3% of the administered dose, respectively) following a single intravenous (IV) dose at 30 mg/kg (0.3 times the MRHD based on adult AUC comparison). In a juvenile animal bone toxicity study, 7-day old rats were dosed intravenously once daily for 28 days with 0, 30, 120, and 500 mg/kg sugammadex (approximately 0.1, 0.6, and 3 times the MRHD, respectively, by adult AUC comparison). Sugammadex at 120 and 500 mg/kg decreased ulna and femur bone lengths by approximately 3%, which did not recover after an 8-week treatment-free period. Reversible whitish discoloration and disturbance of enamel formation were also observed in the incisors at these dose levels. In molars, this effect was only observed at 500 mg/kg. The no-observed-effect-level (NOEL) was 30 mg/kg. In a second juvenile animal bone toxicity study, 7-day old rats were dosed once weekly for 8 weeks with 0, 7.5, 30, and 120 mg/kg (up to 1.2 times the MRHD of 16 mg/kg based on adult AUC comparison). No adverse effects on bone or teeth were noted.

Geriatric use

8.5 Geriatric Use BRIDION has been administered in a dedicated clinical study to a total 102 geriatric patients that compared the time to recovery from neuromuscular blockade induced by rocuronium (0.6 mg/kg) following administration of 2 mg/kg BRIDION given at the reappearance of T 2 in 65-74 year-olds (N=62) and ≥75 year-olds (N=40) compared with 18-64 year-olds (N=48). The median time to recovery of the TOF (T 4 /T 1 ) ratio to 0.9 in 18-64 year-olds was 2.2 minutes; in 65-74 year-olds it was 2.5 minutes, and in ≥75 year-olds it was 3.6 minutes. For time to recovery from neuromuscular blockade induced by rocuronium following administration of 4 mg/kg BRIDION given at 1-2 PTCs, results across clinical trials revealed a median recovery of 2.5 minutes for geriatric patients (≥65 years, N=63) versus 2.0 minutes, for adults aged 18-64 years (N=359). Hence no dose adjustment is necessary in geriatric patients with normal organ function [see Dosage and Administration (2.2) ] . This drug is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ] .

Overdosage

In premarketing clinical trials, one case of accidental overdose with 40 mg/kg BRIDION was reported without significant effects. BRIDION can be removed using hemodialysis with a high-flux filter, but not with a low-flux filter. Based upon clinical studies, BRIDION concentrations in plasma are reduced with a high-flux filter by about 70% after a 3- to 6-hour dialysis session.

Description

(sugammadex) injection, for intravenous use, contains sugammadex sodium, a modified gamma cyclodextrin chemically designated as 6 A ,6 B ,6 C ,6 D ,6 E ,6 F ,6 G ,6 H -Octakis-S-(2-carboxyethyl)-6 A ,6 B ,6 C ,6 D ,6 E ,6 F ,6 G ,6 H -octathio- γ -cyclodextrin sodium salt (1:8) with a molecular weight of 2178.01. The structural formula is: BRIDION is supplied as a sterile, non-pyrogenic aqueous solution that is clear, colorless to slightly yellow-brown for intravenous injection only. Each mL contains 100 mg sugammadex, which is equivalent to 108.8 mg sugammadex sodium. The aqueous solution is adjusted to a pH of between 7 and 8 with hydrochloric acid and/or sodium hydroxide. The osmolality of the product is between 300 and 500 mOsmol/kg. BRIDION may contain up to 7 mg/mL of the mono OH-derivative of sugammadex [see Clinical Pharmacology (12.2) ] .

Mechanism of action

12.1 Mechanism of Action BRIDION is a modified gamma cyclodextrin. It forms a complex with the neuromuscular blocking agents rocuronium and vecuronium, and it reduces the amount of neuromuscular blocking agent available to bind to nicotinic cholinergic receptors in the neuromuscular junction. This results in the reversal of neuromuscular blockade induced by rocuronium and vecuronium.
