pt above 75 years old on atorvastatin 40 , when should it be reduced to

In patients over 75 years old taking atorvastatin 40 mg, the general guidance is to consider a moderate-intensity statin dose based on individual factors such as comorbidities, risk of adverse effects, and patient preference rather than age alone.

For people with hypertension and ischaemic heart disease (secondary prevention), atorvastatin 80 mg is recommended as high-intensity treatment, but doses can be lower (e.g., atorvastatin 20 mg) if there are factors such as chronic kidney disease, drug interactions, increased risk of adverse effects, or patient request for a lower dose. This implies that reducing from 40 mg to a moderate dose (e.g., 10-20 mg) should be considered when such risks or preferences exist.

For primary prevention in older adults over 75 years, atorvastatin 20 mg is the recommended starting dose after consideration of QRISK3 and patient preference, with the possibility to start or reduce the dose accordingly.

There is no specific age-driven mandate to reduce atorvastatin from 40 mg to a moderate-intensity dose; the decision should be individualized, taking into account comorbidities, polypharmacy, frailty, and life expectancy.
