Statins (Formulary)

TAM (Treatments and Medicines) NHS Highland
NHS Highland

Statins are the drugs of first choice for lipid lowering. 

  • All currently available statins have long-term evidence of safety. 
  • For acute coronary syndromes atorvastatin 80mg daily is the drug of choice.
  • If side-effects occur consider a lower dose or alternative statin. Review the dose annually.
  • Interactions: Statins can interact with many drugs, eg diltiazem, verapamil, amiodarone, warfarin, macrolides, antivirals, antifungals. It is important to check for interactions before prescribing and advise patients to avoid drinking grapefruit juice. See: BNF.
  • Muscle effects: Rhabdomyolysis associated with lipid-regulating drugs such as the fibrates and statins appears to be rare (approximately 1 case in every 100 000 treatment years) but may be increased in those with renal impairment and possibly in those with hypothyroidism. Concomitant treatment with drugs that increase plasma-statin concentration increases the risk of muscle toxicity; concomitant treatment with a fibrate and a statin may also be associated with an increased risk of serious muscle toxicity. Refer to BNF.
  • Swallowing difficulties and NG administration: Rosuvastatin capsules are licensed to be opened and the contents administered. In NHS Highland rosuvastatin capsules, are non-formulary except for those patients who have swallowing difficulties, where other statin therapy has not been tolerated, or who require NG tube administration.
