Brevibloc Adverse Reactions

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 clinical practice.
The following adverse reaction rates are based on use of BREVIBLOC (Esmolol Hydrochloride) injection in clinical trials involving 369 patients with supraventricular tachycardia and over 600 intraoperative and postoperative patients enrolled in clinical trials. Most adverse effects observed in controlled clinical trial settings have been mild and transient. The most important and common adverse effect has been hypotension [see Hypotension under Precautions]. Deaths have been reported in post-marketing experience occurring during complex clinical states where BREVIBLOC injection was presumably being used simply to control ventricular rate [see Reactive Airways Disease under Precautions]. (See Table 3.)

Clinical Trial Adverse Reactions (Frequency <3%): Psychiatric Disorders: Confusional state and agitation (~2%); Anxiety, depression and abnormal thinking (<1%).
Nervous System Disorders: Headache (~2%); Paresthesia, syncope, speech disorder, and lightheadedness (<1%); Convulsions (<1%), with one death.
Vascular Disorders: Peripheral ischemia (~1%); Pallor and flushing (<1%).
Gastrointestinal Disorders: Vomiting (~1%); Dyspepsia, constipation, dry mouth, and abdominal discomfort (<1%).
Renal and Urinary Disorders: Urinary retention (<1%).
Post-Marketing Experience: In addition to the adverse reactions reported in clinical trials, the following adverse reactions have been reported in the post-marketing experience. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate reliably their frequency or to establish a causal relationship to drug exposure.
Cardiac Disorders: Cardiac arrest, Coronary arteriospasm.
Skin and Subcutaneous Tissue Disorders: Angioedema, Urticaria, Psoriasis.
