Ivabradineside effects

6. ADVERSE REACTIONS Clinically significant adverse reactions that appear in other sections of the labeling include: Atrial Fibrillation Bradycardia and Conduction Disturbances Most common adverse reactions occurring in ≥ 1% of patients are bradycardia, hypertension, atrial fibrillation and luminous phenomena (phosphenes).

6.1 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 with Heart Failure In SHIFT, safety was evaluated in 3,260 patients treated with Corlanor and 3,278 patients given placebo. The median duration of Corlanor exposure was 21.5 months. The most common adverse drug reactions in the SHIFT trial are shown in Table 2. Table 2. Adverse Drug Reactions with Rates ≥ 1.0% Higher on Ivabradine than Placebo occurring in > 1% on Ivabradine in SHIFT Ivabradine N = 3,260 Placebo N = 3,278 Bradycardia 10% 2.2% Hypertension, blood pressure increased 8.9% 7.8% Atrial fibrillation 8.3% 6.6% Phosphenes, visual brightness 2.8% 0.5% Luminous P henomena (Phosphenes) Phosphenes are phenomena described as a transiently enhanced brightness in a limited area of the visual field, halos, image decomposition (stroboscopic or kaleidoscopic effects), colored bright lights, or multiple images (retinal persistency). Phosphenes are usually triggered by sudden variations in light intensity. Corlanor can cause phosphenes, thought to be mediated through Corlanor’s effects on retinal photoreceptors. Onset is generally within the first 2 months of treatment, after which they may occur repeatedly. Phosphenes were generally reported to be of mild to moderate intensity and led to treatment discontinuation in < 1% of patients; most resolved during or after treatment. Pediatric Patients with Heart Failure The safety of Corlanor in pediatric patients 6 months to less than 18 years of age is based on a clinical trial in symptomatic heart failure patients with dilated cardiomyopathy and elevated heart rate. This trial provides experience in 73 patients treated with Corlanor for a median duration of 397 days, and 42 patients given placebo. Bradycardia (symptomatic and asymptomatic) occurred at rates similar to those in adults. Phosphenes were observed in pediatric patients treated with Corlanor.

6.2 Postmarketing

Experience Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or establish a causal relationship to drug exposure. The following adverse reactions have been identified in adults during post-approval use of Corlanor: syncope, hypotension, torsade de pointes, ventricular fibrillation, ventricular tachycardia, angioedema, erythema, rash, pruritus, urticaria, vertigo, and diplopia, and visual impairment.
