PCSK9 Inhibitors (Evolocumab, Inclisiran) vs Semaglutide (Ozempic / Wegovy / Rybelsus)
Both are used for cardiovascular. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| PCSK9 Inhibitors (Evolocumab, Inclisiran) | Semaglutide (Ozempic / Wegovy / Rybelsus) | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★★ |
| Legal status | FDA Approved | Prescription |
| How it works | Block PCSK9, the protein that degrades LDL receptors — so LDL receptors survive longer and clear far more LDL. Inclisiran is an siRNA silencing PCSK9, dosed twice yearly. | Long-acting agonist of the GLP-1 receptor (GLP1R) — a G-protein-coupled receptor in the pancreas, hypothalamic appetite centres, and vagal afferents. Activation is glucose-dependent: stimulates insulin, suppresses glucagon, slows gastric… |
| In plain English | LDL receptors are the vacuum cleaners that remove bad cholesterol; PCSK9 destroys them. Block PCSK9 and the vacuums keep working — dropping LDL dramatically. Inclisiran is a gene-silencing shot given just twice a year. | It copies a gut hormone that tells your brain "I'm full." Hunger and constant food-thoughts fade; you eat less without willpower. STEP trials: ~15% bodyweight lost in 68 weeks. |
| Bottom line | Most powerful LDL-lowering available; the siRNA form is a genuine leap. | The most powerful weight-loss drug in history until tirzepatide/retatrutide. |
| Availability | Available over the counter | Prescription only |
Which is better for cardiovascular?
Both carry a comparable human-evidence rating (★★★★★). Choose on mechanism fit, side-effects, availability and cost rather than evidence strength alone — they work through different mechanisms.
