Adverse Reactions
The following serious adverse reactions are described in Precautions: Anaphylaxis and Hypersensitivity [see also Contraindications]; Marked Bradycardia.
Clinical Trials Experience: Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adult Patients: The data described as follows 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 3. (See Table 3.)

Pediatric Patients: The safety of BRIDION has been assessed in a randomized, active-controlled study of pediatric patients 2 to <17 years of age, with 242 receiving treatment with BRIDION. Adverse events occurring in ≥5% of pediatric patients are presented in Table 4. The safety profile was generally consistent with that observed in adults. (See Table 4.)

Anaphylaxis and Hypersensitivity: Hypersensitivity reactions, including anaphylaxis, have occurred in both premarketing clinical trials and in post-marketing spontaneous reports. In a dedicated hypersensitivity study in healthy volunteers, the frequency of anaphylaxis was 0.3% [see Anaphylaxis and Hypersensitivity under Precautions]. These reactions 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.
Symptoms associated with these reactions can include: flushing, urticaria, erythematous rash, (severe) hypotension, tachycardia, swelling of tongue, swelling of pharynx, bronchospasm and pulmonary obstructive events. Severe hypersensitivity reactions can be fatal.
A randomized, double-blind study examined the incidence of drug hypersensitivity reactions in healthy volunteers given up to 3 doses of placebo (N=76), sugammadex 4 mg/kg (N=151), or sugammadex 16 mg/kg (N=148). Reports of suspected hypersensitivity were adjudicated by a blinded committee. The incidence of adjudicated hypersensitivity was 1%, 7% and 9% in the placebo, sugammadex 4 mg/kg and sugammadex 16 mg/kg groups, respectively. There were no reports of anaphylaxis after placebo or sugammadex 4 mg/kg. There was a single case of adjudicated anaphylaxis after the first dose of sugammadex 16 mg/kg. The frequency of anaphylaxis for the 299 healthy volunteers treated with intravenous sugammadex was 0.3%. There was no evidence of increased frequency or severity of hypersensitivity with repeat dosing.
In a previous study of similar design, there were three adjudicated cases of anaphylaxis, all after sugammadex 16 mg/kg (incidence 1% in the 298 healthy volunteers treated with sugammadex).
Recurrence of Neuromuscular Blockade: In clinical studies with subjects treated with rocuronium or vecuronium, where BRIDION was administered using a dose labeled for the depth of neuromuscular blockade (N=2022), an incidence of <1% was observed for recurrence of neuromuscular blockade as based on neuromuscular monitoring or clinical evidence [see Risk of Recurrence of Neuromuscular Blockade with Lower Than Recommended Dosing under Precautions].
Bronchospasm: In one dedicated clinical trial and in post-marketing data, in patients with a history of pulmonary complications [see Pulmonary Patients under Precautions], bronchospasm was reported as a possibly related adverse event.
Post-Marketing Experience: The following adverse reactions have been identified during post-approval use of BRIDION. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Cardiac Disorders: Cases of marked bradycardia and bradycardia with cardiac arrest have been observed within minutes after administration of sugammadex [see Marked Bradycardia under Precautions]. Other cardiac rhythm abnormalities have included atrial fibrillation, atrioventricular block, cardiac/cardiorespiratory arrest, electrocardiographic (ECG) ST segment changes, supraventricular tachycardia/extrasystoles, tachycardia, ventricular fibrillation, and ventricular tachycardia. Anaphylaxis associated with ECG ST segment changes (elevation or depression) consistent with myocardial ischemia or coronary spasm has also been reported.
General Disorders and Administration Site Conditions: Cases of BRIDION not having the intended effect.
Immune System Disorders: Hypersensitivity events including anaphylactic shock, anaphylactic reaction, anaphylactoid reaction, and Type 1 hypersensitivity have been reported [see Anaphylaxis and Hypersensitivity under Precautions].
Respiratory, Thoracic, and Mediastinal Disorders: Events of laryngospasm, dyspnea, wheezing, pulmonary edema, and respiratory arrest have been reported.
