Interaction Effect
Increased pravastatin plasma concentrations and increased risk of myopathy
Interaction Summary
Coadministration of pibrentasvir and pravastatin may result in increased pravastatin plasma levels and increase the risk of myopathy, including rhabdomyolysis. Reduce pravastatin dose by 50% when coadministering with pibrentasvir. In a pharmacokinetic study (N=12), when pravastatin 10 mg once daily was coadministered with glecaprevir 400 mg/pibrentasvir 120 mg once daily, pravastatin Cmax increased by 123% and AUC increased by 130%.

Pravastatin Overview
-
Pravastatin is used together with diet, weight-loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease. Pravastatin is also used to reduce the amount of fatty substances such as low-density lipoprotein (LDL) cholesterol ('bad cholesterol') and triglycerides in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol ('good cholesterol') in the blood. Pravastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
-
Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats with pravastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.

Severity Categories
Contraindicated
These drugs, generally, should not be used together simultaneously due to the high risk of severe adverse effects. Combining these medications can lead to dangerous health outcomes and should be strictly avoided unless otherwise instructed by your provider.
Major
This interaction could result in very serious and potentially life-threatening consequences. If you are taking this drug combination, it is very important to be under close medical supervision to minimize severe side effects and ensure your safety. It may be necessary to change a medication or dosage to prevent harm.
Moderate
