Prescribing Information is available at the end of this presentation Summary In patients hospitalised within 10 days of an acute coronary event: –‘Intensive’ lipid-lowering with 80 mg atorvastatin to a median LDL-C of 1.6 mmol/L was associated with a significant reduction in the risk of combined all-cause mortality and major CV events by 16% compared to ‘moderate’ lipid- lowering therapy with 40 mg pravastatin which achieved a median LDL-C of 2.5 mmol/L (P=0.005) –Benefits emerged within 30 days of randomisation with continued divergence of the event curves over time Cannon CP et al.

Prescribing Information is available at the end of this presentation Summary The TNT study is the first randomised trial designed to demonstrate the benefits of lowering LDL-C below 2.6 mmol/L in stable CHD patients Significant (>20%) reductions in CV events including stroke were achieved with atorvastatin 80 mg vs atorvastatin 10 mg Even at high atorvastatin dose, there was a very low incidence of adverse events and no treatment-related rhabdomyolysis The findings add to other data showing the efficacy and safety of high-dose (80 mg) atorvastatin LaRosa JC et al.
