Dosage and Administration
Initiate Ranolazine dosing at 500mg twice daily and increase to 1 g twice daily, as needed, based on clinical symptoms. Take Ranolazine with or without meals. Swallow Ranolazine tablets whole; do not crush, break, or chew. The maximum recommended daily dose of Ranozaline is 1 g twice daily. If a dose of Ranozaline is missed, take the prescribed dose at the next scheduled time; do not double the next dose.
Dose adjustments may be needed when Ranolazine is taken in combination with certain other drugs. Limit the maximum dose of Ranolazine to 500 mg twice daily in patients on diltiazem, verapamil, and other moderate CYP3A inhibitors. Down-titrate Ranolazine based on clinical response in patients concomitantly treated with P-gp inhibitors, such as ciclosporin.
