For Healthcare Professionals
Applies to ranolazine: oral tablet extended release
Other side effects have included peripheral edema (8.3%), fatigue (7%), asthenia (4.4%), vertigo (4.3%), and influenza (4.2%). Other side effects occurring in less than 2% of patients have included tinnitus.
Nervous system side effects have included dizziness (6.2% to 11.8%) and headache (5.5%). Nervous system reactions that were rare (0.5% or less), but potentially medically important, included hypoesthesia, paraesthesia, and tremor. Additional side effects have included confusional state.
Gastrointestinal side effects have included constipation (4.5% to 10.9%), nausea (4.4% to 5.6%), and diarrhea (3.8%). Other, less common reactions (less than 2%) included abdominal pain, dry mouth, and vomiting.
The variable blood levels attained after a given dose of ranolazine (the active ingredient contained in Ranexa) result in a wide range of effects on QTc. At Tmax following repeat dosing at 1000 mg twice a day, the mean change in QTc is about 6 msec. However, in 5% of the population with the highest plasma concentrations, the prolongation of QTc is at least 15 msec. The relationship between ranolazine plasma level and QTc is linear over a concentration range up to 4 fold greater than the concentrations produced by a dosage of 1000 mg twice a day, and this relationship is not significantly affected by age, weight, gender, race, heart rate, congestive heart failure NYHA class, or diabetes. In subjects with hepatic impairment, the relationship between plasma level of ranolazine and QTc is much steeper.
During a long-term safety study (ROLE program) involving patients with chronic angina (n=746), there were no treatment discontinuations due to QTc prolongation and no episodes of Torsades de Pointes were reported.
Cardiovascular side effects occurring in less than 2% of patients have included palpitations, bradycardia, hypotension, orthostatic hypotension, and syncope. ECG abnormalities have included dose- and plasma concentration related increases in the QTc interval, reductions in T wave amplitude, and notched T waves.
In general, a higher incidence of adverse events has been reported in elderly patients 75 years or older than in younger patients.
In general, long-term therapy with ranolazine (the active ingredient contained in Ranexa) is well tolerated in high-risk patients. During a long-term safety study (ROLE program) involving patients with chronic angina (n=746), more than two years after initial dosing, 76.7% of patients remained on therapy and 9.7% discontinued ranolazine due to adverse effects. In this study, age (greater than or equal to 64 years) was associated with increased adverse effects related withdrawals.
Renal side effects have included small, reversible elevations in serum creatinine and BUN levels. These elevations were observed without evidence of renal toxicity. Renal failure has been rarely (less than 0.5%) reported.
Metabolic side effects have been minimal. Ranolazine does not appear to significantly affect triglyceride or blood glucose levels; however, diabetes has been reported as an adverse effect. In contrast, in patients with diabetes, ranolazine (the active ingredient contained in Ranexa) has produced a dose-related reduction in glycosylated hemoglobin (HbA1c).
Respiratory side effects have included cough (6%) and dyspnea (4.3%). Pulmonary fibrosis has been rarely (less than 0.5%) reported.
Musculoskeletal side effects have included back pain (4.8%) and arthralgia (4.4%).
Hematologic side effects have included anemia (4.6%). Additional side effects have included thrombocytopenia, leukopenia, and pancytopenia (less than 0.5%).
Hypersensitivity side effects have included angioedema and eosinophilia (less than 0.5%).
Psychiatric side effects have included post marketing reports of hallucinations.
Dermatologic side effects have included angioedema, pruritus and rash.
