FDA approves first oral PCSK9 inhibitor for high cholesterol

Overview

Updated Jul 16

For a decade, the most powerful cholesterol drugs came only as shots. On July 16, 2026, the FDA approved Merck's Lipfendra, a once-daily pill that cut LDL cholesterol about as much as those injections did.

PCSK9 inhibitors cut 'bad' cholesterol by more than half, but the needle and the price kept many patients away. Lipfendra costs $315 a month, below the $500-to-$600 injections. Whether it also prevents heart attacks and strokes won't be confirmed until a large trial reports in 2029.

Why it matters

The strongest cholesterol medicine now comes as a daily pill, cheaper than the shots. If insurers cover it, far more patients could reach it.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

September 1987

First statin approved (1987)

The FDA approved lovastatin (Mevacor) from Merck, the first statin. It was a daily pill that lowered LDL cholesterol by blocking an enzyme the liver uses to make it. Nothing so effective and convenient had existed before.

Then

Statins spread quickly as safe, easy-to-take pills for a common problem.

Now

They became among the most-prescribed drugs in the world and are now cheap generics that anchor cholesterol care.

Why this matters now

A potent oral pill, again from Merck, is what turned cholesterol lowering into mass-scale medicine. Lipfendra aims to do the same for a class stuck behind needles.

July-August 2015

PCSK9 injections launch (2015)

The FDA approved Amgen's Repatha and Regeneron and Sanofi's Praluent, the first PCSK9 inhibitors. Both cut LDL sharply but had to be injected, and both launched near $14,000 a year. Insurers built strict prior-authorization walls.

Then

Early sales badly missed forecasts as payers blocked access and patients balked at the price.

Now

The makers later cut prices by about 60%, and outcomes trials proved the drugs reduce heart attacks, slowly widening use.

Why this matters now

This class works, but injections and price throttled it for years. Lipfendra's lower price and pill form are a direct answer to that history.

September 2019

First oral GLP-1 approved (2019)

The FDA approved Rybelsus (oral semaglutide), the first pill version of a GLP-1 drug for type 2 diabetes, a class that had been injection-only. It proved a large peptide could be formulated into a daily tablet.

Then

The pill expanded a fast-growing class to patients who resisted shots, though it required careful dosing on an empty stomach.

Now

It set the template for turning injectable biologic mechanisms into oral drugs, now a major industry race.

Why this matters now

Lipfendra is another oral take on an injection-only mechanism. Rybelsus shows both the access upside and the practical tradeoffs of moving a peptide into a pill.
