By Peter A. McCullough, MD, MPHIt has been several years since the introduction of a new oral drug to lower cholesterol.  However, the injectable market has become crowded with more choices for those needing cholesterol-lowering.  Merck’s new drug will almost certainly be disruptive in the marketplace.💊 Merck’s Lipfendra: The First Oral PCSK9 Inhibitor Arrives — Mixed News for Statin HatersThe FDA dropped a bombshell on July 17, 2026, approvingLipfendra (enlicitide)— Merck’s once-daily oral PCSK9 inhibitor. This isn’t just another cholesterol drug. It’s the firstpillcapable of doing what previously required a needle, and it slashes LDL-C by56–59%on top of maximally tolerated statins. For millions of Americans who’ve been waged war on generic statins, this changes the calculus entirely.🔬 Side Effects: Lipfendra vs. Statins — No ContestLet’s be blunt about what statins actually do to people. In ~15% of people, there are well-documented muscle pain, weakness—the problem is that 100% of the general public has these complaints as well.Now look at Lipfendra’s side effect profile from the two pivotal trials across 3,207 patients:In the larger ASCVD trial, adverse reactions weresimilar between Lipfendra and placebo— meaning the drug was essentially indistinguishable from a sugar pill in side effect burden. The HeFH trial showed mild upticks in diarrhea and dizziness, but nothing approaching the metabolic and muscular devastation statins routinely inflict.The fasting requirement — eight hours overnight, take it 30 minutes before breakfast — is annoying, but Merck appears to have dosed at 20 mg to build in a compliance buffer. Compared to waking up every morning feeling like you got hit by a truck on atorvastatin, an empty stomach is a trivial inconvenience.Subscribe nowRead more
