Ranolazine
Summary
Ranolazine is primarily used to treat chronic angina, which is chest pain that occurs due to heart disease. It helps improve blood flow to the heart muscle, reducing the strain on the heart and making it function more efficiently.
Ranolazine works by inhibiting certain sodium and calcium channels in heart cells. This helps reduce stress on the heart cells and improves the usage of oxygen, which in turn reduces symptoms of angina, such as chest pain.
The usual starting dose of Ranolazine for adults is 500 mg taken twice daily. This can be increased to 1000 mg twice daily based on individual response. The tablets should be swallowed whole, with or without food.
Common side effects of Ranolazine include dizziness, headache, constipation, nausea, and fatigue. More serious side effects, although rare, can include an abnormal heart rhythm known as QT prolongation, low blood pressure, or liver enzyme abnormalities.
Ranolazine should be used with caution in patients with liver disease or severe kidney impairment. It is not recommended for patients with preexisting QT prolongation or those taking certain other medications that affect the QT interval. It can interact with other drugs that affect CYP3A enzymes, so it's important to consult a healthcare provider before starting or combining treatments.
