Big pharma often gets a rather rough ride here on Techdirt, what with its attempts to stop governments granting licenses for life-saving and low-cost generics in emerging countries, engaging in legal action to prevent drug safety information being released, and paying kickbacks to doctors. But sometimes you get the impression that drug companies really go out of their way to be disliked, as this great post by Josh Bloom on the Medical Progress Today site, pointed out to us by John Wilbanks, demonstrates:
[Merck] just received approval for the cholesterol-lowering combination drug Liptruzet -- a functionally similar (identical?) version of their own Vytorin, which is a combination of their statin Zocor and Schering's (now part of Merck) cholesterol absorption blocker Zetia (ezetimibe).Liptruzet, ironically happens to be a combination of Zetia and atorvastatin (generic Lipitor). Yes -- Merck is substituting a former Pfizer drug for their own Zocor with combining it with Zetia to make a "new" medication with additional patent protection.
[Liptruzet] reduced LDL cholesterol more for patients who took Lipitor alone, but it did not reduce patients' chances of developing heart disease. Not surprisingly, this left some doctors to wonder why it was approved at all.
"The modern movement requires that drugs not just be safe and effective in their immediate goal, but to also show efficacy in improving outcomes. Cardiac medications should not just reduce the cholesterol count, but reduce the risk of heart attack and stroke as well." He continues, "There was, I'm sure, pressure by big pharma to get this approved, which by pairing it with another drug, would in effect restore blockbuster Lipitor back to branded status."
Over 14.5 years, the cholesterol-lowering medicine has made over $125 billion in sales, and has provided up to a quarter of Pfizer Inc.'s annual revenue for years.
This episode just plain smells bad on many levels. I get the feeling that just about everything except science is driving this, and this will be a black eye that Merck will be inflicting on itself and the rest of the industry.
