What is Ranexa?
Ranexa drug is a prescription medication commonly used to treat the symptoms of ongoing chest pain or discomfort (chronic angina, i.e., pressure that is felt when the heart does not get enough oxygen) that keeps coming back. Angina comes on when extremely little oxygen reaches your heart muscle.
It is often brought on by exercise or too much activity. Ranexa can be used alone or with other drugs. You can buy Ranexa online for your chest pain from our reliable pharmacy website.
Ranexa belongs to a class of drugs known as Antianginal, Non-nitrates. Ranexa works by improving blood flow to help your heart work more efficiently.
It is not for use during an acute (or emergency) angina attack. Ranexa reduces the number of times you may experience chest pain. Relieving symptoms of angina will increase your ability to exercise and perform strenuous work. Ranexa (or Ranolazine) works differently than other medications for angina.
Therefore, Ranexa can be used with other medicines for blood pressure control and heart problems. It can be taken with other angina medicines (including nitrates, beta-blockers such as metoprolol, calcium channel blockers such as amlodipine).
Is Ranexa a blood thinner?
Ranexa is not a blood thinner. Ranexa acts by improving how well your heart uses oxygen to do more work with less oxygen. This medication is usually used with ACE inhibitors, calcium channel blockers, angiotensin receptor blockers, beta-blockers, or nitrates.
This drug is usually available only with a doctor’s prescription. Ranexa is available in the following dosage forms: Tablet, Ranexa ER. It is unknown if Ranexa is safe and effective in children younger than 18 years.
How long does it take for Ranexa to work?
Ranolazine (or Ranexa) does not work very fast and usually takes around 4 hours for peak effect. The apparent terminal half-life of Ranexa is about 7 hours. A steady-state is generally achieved within three days of twice-daily dosing with Ranexa.
Mechanism of action of Ranexa
Ranexa inhibits persistent or late inward sodium current in heart muscle in various voltage-gated sodium channels. Inhibiting that sodium current causes reductions in intracellular calcium levels. This, in turn, causes reduced tension in the heart wall, resulting in reduced oxygen requirements for the muscle.
Ranexa may help control your condition. However, it will not cure it. Continue to take Ranexa even if you feel well. Do not stop taking Ranexa abruptly without talking to the doctor. Don’t use Ranexa for a condition for which it wasn’t prescribed. Don’t give Ranexa to others, even if they have the same condition as yours. It can harm them.
