doubling statin dose - approximate increase in cholesterol lowering if double dose of statins

Last reviewed 01/2018

  • if the dose of a statin is doubled then there is an approximate 6% increase in LDL lowering efficacy by doubling the dose - the so-called 6 percent rule

    • for example
      • rosuvastatin statin 5mg produces an approximate LDL reduction of 40% - if the dose of rosuvastin is doubled to 10mg then there is an approximate 46% LDL reduction expected with this dose of rosuvastatin
      • pravastatin 20mg produces an approximate LDL reduction of 24% - if the dose of pravastatin is doubled to 40mg then there is an approximate 30% LDL reduction expected with this dose of pravastatin

    • the "6 percent rule" holds approximately for all statins (1,2)
