Lipfendra (enlicitide) is the first once-daily oral PCSK9 inhibitor, FDA-approved in 2026 to lower LDL ("bad") cholesterol in adults with high cholesterol, including familial hypercholesterolemia. Until now, PCSK9 inhibitors only came as injections — Lipfendra brings that same LDL-lowering mechanism to a daily pill.
Lipfendra (enlicitide) is a macrocyclic peptide — a small, ring-shaped molecule — made by Merck. It works the same way as injectable PCSK9 inhibitors like Repatha and Praluent, but is taken as a tablet instead of a shot.
How Does Lipfendra Work?
PCSK9 is a protein made by the liver that normally destroys LDL receptors on liver cells. Fewer LDL receptors means less LDL cholesterol gets cleared from the bloodstream, so LDL levels rise. Enlicitide binds to PCSK9 and blocks it from doing this, so:
- More LDL receptors stay on the liver cell surface instead of being broken down
- The liver clears more LDL cholesterol from the blood with each pass
- LDL levels drop substantially on top of statin therapy
Who Is Lipfendra For?
Lipfendra is FDA-approved as an add-on to diet and exercise to lower LDL cholesterol in adults with hypercholesterolemia, including heterozygous familial hypercholesterolemia (HeFH). It's intended for patients who need additional LDL lowering beyond what diet, exercise, and other cholesterol medications (like statins) have achieved on their own.
💉 Why an oral option matters: Injectable PCSK9 inhibitors are highly effective, but some patients prefer to avoid injections, or have needle anxiety, dexterity limitations, or trouble with the cold-chain storage injectables require. A once-daily pill removes that barrier for eligible patients.
How to Take Lipfendra
| Step | Instruction |
|---|---|
| Dose | One 20 mg tablet by mouth, once daily |
| Timing | On an empty stomach, in the morning, with water, black coffee, or plain tea only |
| Before eating | Wait at least 30 minutes before eating food or drinking anything other than water, black coffee, or plain tea |
| Swallowing | Swallow the tablet whole — do not split, crush, or chew it |
Taking Lipfendra with food, or with beverages other than water/black coffee/plain tea, can reduce how well it's absorbed — so the empty-stomach timing is an important part of making the medication work as intended.
Side Effects and Safety
In clinical trials of patients with familial hypercholesterolemia, the most common side effects were:
- Diarrhea — 7% of patients on Lipfendra vs. 2% on placebo
- Dizziness — 9% of patients on Lipfendra vs. 4% on placebo
⚠️ Pregnancy: Lipfendra may cause fetal harm based on its mechanism of action and should not be used during pregnancy. Tell your provider right away if you become pregnant or are planning pregnancy while taking this medication. Data on use during breastfeeding is limited — discuss with your provider.
Lipfendra vs. Injectable PCSK9 Inhibitors
| Drug | Form | Dosing |
|---|---|---|
| Lipfendra (enlicitide) | Oral tablet | 20 mg once daily, empty stomach |
| Repatha (evolocumab) | Subcutaneous injection | 140 mg every 2 weeks or 420 mg monthly |
| Praluent (alirocumab) | Subcutaneous injection | 75–150 mg every 2 weeks |
All three work through the same PCSK9-blocking mechanism and are used in similar patients. The right choice depends on your preference for a daily pill vs. an every-2-week or monthly injection, insurance coverage, and your provider's assessment of your cholesterol profile.
