Atorvastatina: ASCOT-LLA

ASCOT este un studiu multicentric, international ce a avut ca scop principal comparatia a doua tratamente (clasic/inovator) intr-un design factorial:

• Design PROBE (Prospective, Randomized, Open, Blinded End point) ce a comparat 2 tratamente antihipertensive

• Studiu dublu-orb, controlat placebo ce a inclus tratamentul cu atorvastatina de 10 mg intr-o cohorta extinsa selectata din populatia antihipertensiva a studiului (lipid-lowering arm [ASCOT-LLA])

ASCOT a inclus aproape 20,000 de pacienti hipertensivi cu multipli factori de risc

• Importante, tinand cont de timpul relativ scurtLarge given the short follow-up time (median 3.3 years) and emerged earlier than in many other statin trials (3,3 ani) si au aparut mai repede decat in cazul altor statine

• Nu au diferit semnificativ in cadrul grupurilor

• Nu s-au corelat cu nivelul initial de colesterol

Beneficiile utilizarii statinelor

• Scaderea semnificativa a mortalitatii si morbiditatii

• Reducerea evenimentelor cardiovasculare a fost

demonstrata atat pentru pacienti cu risc scazut, cat si pentru

cei cu risc inalt

• In plus, reducerea valorilor LDL-c a demonstrat beneficii

chiar si la pacientii cu colesterol normal sau doar usor

crescut

• ALT/AST elevations > 3x ULN:

• 0.5% of patients treated with atorvastatin 10 to 80 mg experienced ALT/AST elevations > 3x ULN.

• Myalgia

• Incidence of myalgia across all the atorvastatin doses was low (1.9%) and directly comparable to the incidence of myalgia observed in patients receiving other statins combined.

Source: Pfizer Inc. Data on file. Review of 44 completed clinical trials.

• A recent analysis of 44 completed clinical trials demonstrated

that atorvastatin is well tolerated and has excellent safety

across the 10 mg to 80 mg atorvastatin dose range.

• The overall incidence of AEs with atorvastatin in clinical trials

does not increase across the dose range, and is similar to

that observed with placebo, and in patients treated with other

statins.

• Specific analysis of musculoskeletal and hepatic AEs showed

that these occurred infrequently and rarely resulted in

treatment discontinuation.
