Methoxylated Flavones and Pravastatin Sodium

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP)

Why this applies to Pravastatin Sodium

Pravastatin Sodium falls under ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP) — the group Methoxylated Flavones interacts with.

In vitro, methoxylated flavones inhibit organic anion transporting polypeptide (OATP) 1B1, 1B3, and 2B1. This may reduce the bioavailability of oral drugs that are substrates of OATP. However, this interaction has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for pravastatin (Pravachol). To do its cholesterol-lowering job, pravastatin has to be carried into your liver cells by special transporters called OATPs. In lab dish studies, citrus peel compounds known as methoxylated flavones appear to block those same transporters. If that were to happen in people, less pravastatin would reach the liver, which could make it work a little less well at lowering your LDL (the "bad" cholesterol).

The important caveat: this comes only from test-tube research and has never actually been seen in humans. Everyday culinary amounts of citrus are very unlikely to matter; concentrated supplements are the bigger question mark. There's no need to worry, but if you're considering a supplement like this, run it by your pharmacist or doctor first.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

About Methoxylated Flavones

What is Methoxylated Flavones?

  • Antioxidant support
  • Circulation and blood vessel health
  • Anti-inflammatory support
  • Skin and aging support
  • General 'metabolism' or wellness blends

Methoxylated flavones (often called polymethoxyflavones) are a group of plant compounds, found mainly in citrus peel, that include substances like nobiletin and tangeretin. Lab and animal studies suggest possible antioxidant and anti-inflammatory effects, but solid human research is very limited, so their real-world benefits are unproven. Talk with a pharmacist or doctor before using them, especially if you take medicines or are pregnant or breastfeeding.

About Pravastatin
