Interaction Details
Vericiguat is classified as belonging to the following category: P-Glycoprotein Substrates
Theoretically, concomitant use might alter the effects and adverse effects of P-glycoprotein substrates.
There is preliminary evidence that quercetin inhibits the gastrointestinal P-glycoprotein efflux pump, which might increase the bioavailability and serum levels of drugs transported by the pump. A small study in healthy volunteers reported that pretreatment with quercetin increased bioavailability and plasma levels after a single dose of cyclosporine (Neoral, Sandimmune). Also, two small studies have shown that quercetin might decrease the absorption of talinolol, a substrate transported by the gastrointestinal P-glycoprotein efflux pump. However, in another small study, several days of quercetin treatment did not significantly affect the pharmacokinetics of saquinavir (Invirase). The reason for these discrepancies is not entirely clear. Until more is known, use quercetin cautiously in combination with P-glycoprotein substrates.

Quercetin Overview
Quercetin is a type of flavonoid, which is a class of compounds found in a wide variety of plants and foods. It is purported to have a number of health benefits such as anti-inflammatory, antioxidant, and immune-boosting effects. Studies suggest it may also help to reduce the risk of certain chronic diseases, such as heart disease. In addition, quercetin may have anti-allergic properties and may be helpful in the treatment of allergies and asthma. It is a popular dietary supplement worldwide and is often included in products that contain antioxidants or various vitamins/minerals. Its wide range of potential health benefits mean that it could potentiate the effects of other drugs (e.g., anti-hypertensives), which is why there are an abundant number of potential interactions listed for quercetin.
Vericiguat Overview
-
Vericiguat is used to reduce the risk of death and need for hospitalization in certain adults with heart failure. Vericiguat is in a class of medications called soluble guanylate cyclase (sGC) stimulators. It works by relaxing the blood vessels in the lungs to allow blood to flow easily.
