Danshen and Rosuvastatin

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

Moderate

ROSUVASTATIN (Crestor)

Theoretically, danshen might increase the levels and clinical effects of rosuvastatin.
Animal research shows that a single dose of danshen increases levels of rosuvastatin at least 2-fold, possibly by increasing absorption and/or decreasing elimination. So far, 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 explains PharmD, Clinical Pharmacist

Here's the gist with Danshen and rosuvastatin (Crestor). Rosuvastatin works as-is, it isn't a prodrug, so anything that raises its blood levels tends to amplify both its effects and its side effects. In animal studies, a single dose of Danshen roughly doubled rosuvastatin levels, likely by boosting how much gets absorbed or slowing how it leaves the body. More drug hanging around can mean a higher chance of muscle aches, weakness, or, rarely, more serious muscle problems and liver irritation.

I'll be honest though, this hasn't actually been seen in people yet, so it's more of a theoretical, lab-based concern. Still, since Danshen can also affect blood clotting, it's worth running it by your pharmacist or doctor before combining the two.

From our pharmacist’s overview on the Rosuvastatin page

“Rosuvastatin (Crestor, Ezallor) is a statin taken daily for years to lower cholesterol, and its supplement list deserves real scrutiny, not a quick skim. Five of the 63 ingredients on file carry a major rating, headed by grapefruit, which can raise statin blood levels, and by heavy drinking, since beer and wine compound the strain this…”

About Danshen

What is Danshen?

  • Heart and circulation support
  • Angina (chest pain)
  • High blood pressure
  • Anxiety and stress
  • Liver health

Danshen is a root used in traditional Chinese medicine, mainly for heart and circulation problems. Some early research is promising, but the evidence is not strong enough to confirm it works for any condition, and it may affect blood clotting. Talk to a pharmacist or doctor before using it, especially if you take other medicines or have a health condition.

About Rosuvastatin

What Is Rosuvastatin Used For?

Brand names: Crestor, Ezallor

Rosuvastatin tablets are used alongside diet changes to lower LDL-C ("bad" cholesterol), total cholesterol, and triglycerides (blood fats), and to raise HDL-C ("good" cholesterol) in adults with high cholesterol or mixed cholesterol problems. They are also used in adults with very high triglycerides, a condition called primary dysbetalipoproteinemia (Type III, a genetic fat-metabolism disorder), and to slow the buildup of plaque in arteries (atherosclerosis).

In people without established heart disease but with multiple risk factors, rosuvastatin tablets can reduce the risk of heart attack, stroke, and procedures to open blocked arteries. For children and teens aged 8 and older with heterozygous familial hypercholesterolemia (HeFH, an inherited high-cholesterol condition), the tablet form is used to lower LDL-C after diet alone has not worked. Crestor tablets are also approved to treat homozygous familial hypercholesterolemia (HoFH, a more severe inherited form) in adults and in children aged 7 and older.
