Prasugrel

Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026

Prasugrel is a third-generation thienopyridine P2Y12 inhibitor with faster onset, greater potency, and less inter-patient variability than clopidogrel. The TRITON-TIMI 38 trial demonstrated superior efficacy over clopidogrel in ACS patients undergoing PCI, but with higher bleeding risk. Its single-step hepatic activation avoids the CYP2C19 polymorphism issue seen with clopidogrel.

In short

What the research says.

A quick, data-only summary. The full evidence, dosing, and sources are below.

Prasugrel is a third-generation thienopyridine P2Y12 inhibitor with faster onset, greater potency, and less inter-patient variability than clopidogrel. NutriStack rates the supporting evidence as strong. Common adult dosing is 60 mg loading dose, then 10 mg once daily (5 mg daily if <60 kg) for up to 12 months with aspirin (as prescribed by your physician), though a prescriber sets the actual dose. This profile indexes 10 sources.

What it's good for
  • Superior to clopidogrel in reducing ischemic events in ACS-PCI (TRITON-TIMI 38)6,7
  • Faster onset of platelet inhibition than clopidogrel
  • More consistent antiplatelet effect (not affected by CYP2C19 polymorphism)3,8
  • Greater reduction in stent thrombosis than clopidogrel6,7
What to watch for
  • Bleeding (higher rate than clopidogrel, including life-threatening and fatal bleeding)
  • Bruising
  • Epistaxis
  • Active pathological bleeding3
  • History of prior stroke or TIA (net clinical harm demonstrated)

The bottom line

Evidence rating strong. Most-documented uses: superior to clopidogrel in reducing ischemic events in acs-pci (triton-timi 38), faster onset of platelet inhibition than clopidogrel, more consistent antiplatelet effect (not affected by cyp2c19 polymorphism). 10 sources indexed (2017–2023), with 0 interaction records on file.

The science

How it works, mechanistically.

Core mechanism

Thienopyridine prodrug that requires only a single CYP-mediated hepatic oxidation step (primarily CYP3A4 and CYP2B6) to generate the active metabolite. The active metabolite irreversibly binds to the platelet P2Y12 ADP receptor, blocking ADP-mediated platelet activation and aggregation. Faster and more complete platelet inhibition than clopidogrel, with minimal impact from CYP2C19 polymorphisms.

Quick answers about Prasugrel, drawn from the data on this page.

What is Prasugrel?

Prasugrel is a third-generation thienopyridine P2Y12 inhibitor with faster onset, greater potency, and less inter-patient variability than clopidogrel. The TRITON-TIMI 38 trial demonstrated superior efficacy over clopidogrel in ACS patients undergoing PCI, but with higher bleeding risk. Its single-step hepatic activation avoids the CYP2C19 polymorphism issue seen with clopidogrel.

What is Prasugrel used for?

Commonly cited benefits of Prasugrel include: Superior to clopidogrel in reducing ischemic events in ACS-PCI (TRITON-TIMI 38); Faster onset of platelet inhibition than clopidogrel; More consistent antiplatelet effect (not affected by CYP2C19 polymorphism); Greater reduction in stent thrombosis than clopidogrel. NutriStack rates the overall evidence as strong.

What is a typical dose of Prasugrel?

A typical adult dose of Prasugrel is 60 mg loading dose, then 10 mg once daily (5 mg daily if <60 kg) for up to 12 months with aspirin (as prescribed by your physician). The commonly recommended form is Oral tablet. These are general ranges, not personalized advice; confirm the right dose with a clinician.

What are the side effects of Prasugrel?

Reported side effects include bleeding (higher rate than clopidogrel, including life-threatening and fatal bleeding), bruising, epistaxis, gi bleeding, anemia, rash. This is educational information; check with a healthcare professional before use.

How strong is the evidence for Prasugrel?

NutriStack rates this as Strong, meaning multiple high-quality meta-analyses or systematic reviews converge on the same finding. Full tier criteria are at https://nutristackapp.com/methodology/evidence-tiers.
