Dr Heiner Berthold and colleagues tested commercial garlic oil preparations and found no evidence of lowered cholesterol levels.
Most doctors agreed that the difference was probably because the Lipitor lowered cholesterol a lot more than Pravachol.
In clinical trials, adding Zetia to Lipitor lowered cholesterol more than Vytorin does.
But 301012 should work--in early stage trials it lowered cholesterol 50%.
Vytorin critics said the problem was that a new component in the drug, the chemical ezetimibe, lowered cholesterol but hadn't been proven to prevent heart attacks or deaths.
We saw that most vividly with torceptrapib, the Pfizer drug that raised the good cholesterol, lowered the bad cholesterol and increased the risk of death.
FORBES: AstraZeneca Study is Good News for the Public, Bad News for AstraZeneca
But when Zetia was combined with a statin like Lipitor or Zocor, it lowered bad cholesterol, or low-density lipoprotein (LDL), more than anything else out there.
He will continue to prescribe the drug to his patients, who all suffer from the genetic illness familial hypercholesterolemia and desperately need their cholesterol lowered, but he wants more evidence about how Zetia works before a big study of the drugs benefits concludes in 2012, at least a year later than originally expected.
Mice from all three groups lost weight when they exercised, and their cholesterol levels lowered.
So long as a patient's bad cholesterol was lowered to the level recommended by national guidelines, what was the difference?
But even when cholesterol was lowered by the same amount, on a percentage basis, Lipitor seemed to do better at preventing plaque accumulation than Pravachol.
But now an experimental medicine has lowered Nottingham's bad cholesterol to below 100 milligrams, the lowest level ever for a patient with the severe form of hypercholesterolemia.
He added there were still debates to be had, such as working out more about who benefited the most from the drugs and how far cholesterol should be lowered.
Moreover, if TAK-475 is no more powerful than Zetia but has additional liver toxicity, its market will be limited to patients whose cholesterol is not lowered by the combination of a statin like Crestor and Zetia.
Pfizer had aimed to develop its own ACAT inhibitor, but the drug failed to show a benefit. (See: Pfizer's Cardiovascular Failure) But some of the problems with that drug may have come from the fact that it interacted with Lipitor, preventing cholesterol from being lowered enough.
So long as they lowered their LDL, or bad cholesterol, by the same amount, their arteries did equally well, Howard says.
More important, Crestor cut bad cholesterol 60% and lowered CRP.
But the two-year Crestor results actually rival the cleaning done by the so-called "artery Drano" ETC-216, a "good cholesterol" drug that lowered the plaque volume by 4% in 47 patients in only five weeks.
It also lowered the so-called good cholesterol, or high-density lipoprotein (HDL), and it did not enter the cell, a characteristic Medford wanted hisdrug to have, because some of the oxidation process takes place within cellular membranes.
The combo also lowered the low-density, or "bad, " cholesterol 17% more than Lipitor alone.
