What is Ranolazine?

Ranolazine is a prescription medicine used to treat chronic angina in adults. It is an oral antianginal drug that helps prevent chest pain when activity or stress occurs. Unlike nitrates or beta blockers, ranolazine does not reliably lower heart rate or blood pressure. It is a piperazine derivative with a distinct mechanism in heart muscle cells.

How does it work?

The drug reduces late sodium current in heart muscle. By limiting this flow, it lowers calcium overload during episodes of low oxygen. That helps the heart relax and improves blood flow to the heart tissue. Many patients notice fewer angina episodes and more stable exercise tolerance. The effect is usually independent of resting heart rate or blood pressure.

How and when to take

The usual starting dose is 500 mg taken twice daily. If well tolerated and there are no conflicting medicines, the physician may raise it to 1000 mg twice daily. Do not exceed 1000 mg twice daily. People with liver problems need careful dose adjustments and severe liver disease is a contraindication.

Indications and important limits

Ranolazine is intended for chronic, stable angina as part of a broader treatment plan. It is not a medicine for immediate relief of chest pain or a quick fix during an angina attack. It can be used alongside nitrates, calcium channel blockers, and statins in many regimens, but the exact plan depends on the patient.

Safety and side effects

Common side effects are dizziness, headache, constipation, and nausea. Some people feel fatigue at the start of therapy. A rare but serious risk is QT interval prolongation on an ECG, which may lead to irregular heartbeats. Seek medical help for fainting, chest pain or a nearly abnormal heartbeat. Most side effects appear early and improve with time.

Interactions and precautions

Ranolazine is metabolized by CYP3A enzymes. Do not use it with strong CYP3A inhibitors such as ketoconazole, itraconazole, clarithromycin, ritonavir, or certain HIV protease inhibitors. It may interact with drugs that prolong the QT interval. Tell your doctor about all medicines, including over‑the‑counter products and supplements. If you have a history of rhythm problems, discuss this before starting treatment.

Special considerations

Old age, kidney problems, or liver disease can affect dosing. In hepatic impairment, the medicine is usually avoided or reduced. Pregnant or breastfeeding women should discuss risks with a clinician. Alcohol use and electrolyte problems may increase side effects or heart rhythm changes. Regular monitoring by a clinician is common in longer courses of therapy. Your doctor may adjust the plan based on response and tolerance.

Storage and administration tips

Store ranolazine tablets at room temperature, away from moisture and heat. Keep them out of reach of children. Do not crush or split tablets unless your pharmacist instructs you. You may take the medicine with or without food, but try to keep a consistent schedule. If you miss a dose, resume as directed by your doctor, without doubling up. Consult the pharmacist if you have questions about storage or dose adjustments.
