Rancad (Ranolazine 1000mg)

Rancad general information

What is Rancad used for?

Rancad tablets 1000mg are used to treat chronic stable angina in patients who are not adequately controlled by other medications alone or who cannot tolerate other medications due to side effects.  Angina is a symptom of coronary artery disease, also known as ischemic heart disease, in which there is insufficient blood flow to the heart due to blocked arteries, resulting in a lack of oxygen to the heart muscles and this causes chest pains.  Rancad extended release tablets 1000mg increase oxygen supply to the heart and helps the heart work more efficiently, which relieves symptoms of chronic stable angina and reduces the risk of heart attack.  Rancad tablets 1000mg can be used in conjunction with other anti-angina medications including beta blockers or calcium channel blockers, but should not be used to treat acute attack of angina. 

How does Rancad work?

Rancad tablets 1000mg contain ranolazine, a sodium channel inhibitor that is used to treat chronic stable angina.  Ranolazine in Rancad tablets 1000mg works through a novel mechanism to increase oxygen supply to the heart.  Sodium and calcium ions enter heart muscle cells (myocytes) through specific ion channels and cause myocyte contraction.  When heart muscle cells are starved of oxygen due to insufficient oxygen supply, ventricular tension increases (a measure of cardiac oxygen consumption), which increases need for oxygen.  Ranolazine in Rancad tablets 1000mg blocks the late phase of flow of sodium ions into the myocyte after a contraction, which also reduces inflow of calcium ions, which reduces ventricular tension and causes myocardial (heart muscle) relaxation and thereby, a reduction in oxygen consumption.  This action of ranolazine in Rancad tablets 1000mg reduces symptoms of angina like chest pains, without changing heart rate or blood pressure, or vasodilation (relaxation and widening of blood vessels).

What does Rancad contain?

Rancad tablets 1000mg contain the active ingredient ranolazine, a sodium channel inhibitor that is used to treat chronic stable angina in patients who are not adequately controlled by other medications alone or who cannot tolerate other medications due to side effects.
