How it works

From the US prescribing label for the same active substance (Ranolazine). It describes the substance, not this exact product.

The mechanism of action of ranolazine’s antianginal effects has not been determined.

Ranolazine has anti-ischemic and antianginal effects that do not depend upon reductions in heart rate or blood pressure.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

Ranolazine is extensively metabolized in the gut and liver and its absorption is highly variable.

How it leaves the body

Following a single oral dose of ranolazine solution, approximately 75% of the dose is excreted in urine and 25% in feces.

With food

The pharmacokinetics of ranolazine is unaffected by age, gender, or food.
