EFFIENT (prasugrel hydrochloride)
Effient (prasugrel) is a P2Y12 platelet inhibitor indicated to reduce the rate of thrombotic cardiovascular events, including stent thrombosis, in patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI). It is indicated for patients with unstable angina (UA), non-ST-elevation myocardial infarction (NSTEMI), or ST-elevation myocardial infarction (STEMI) undergoing primary or delayed PCI. Clinical data demonstrates a reduction in the combined endpoint of cardiovascular death, nonfatal MI, or nonfatal stroke compared to clopidogrel, a benefit driven primarily by a reduction in MI.
How EFFIENT Works
Prasugrel is an inhibitor of platelet activation and aggregation. It is a prodrug that requires metabolic conversion to an active metabolite, which then binds irreversibly to the P2Y12 class of adenosine diphosphate (ADP) receptors on platelets. This permanent binding prevents ADP-mediated activation of the GPIIb/IIIa complex, thereby inhibiting platelet aggregation for the remainder of the platelet's lifespan.

EFFIENT Boxed Warning
BLEEDING RISK Effient can cause significant, sometimes fatal, bleeding [see Warnings and Precautions (5.1 , 5.2) and Adverse Reactions (6.1) ] . Do not use Effient in patients with active pathological bleeding or a history of transient ischemic attack (TIA) or stroke [see Contraindications (4.1 , 4.2) ] . In patients ≥75 years of age, Effient is generally not recommended, because of the increased risk of fatal and intracranial bleeding and uncertain benefit, except in high-risk situations (patie...
WARNING: BLEEDING RISK Effient can cause significant, sometimes fatal, bleeding [see Warnings and Precautions (5.1 , 5.2) and Adverse Reactions (6.1) ] . Do not use Effient in patients with active pathological bleeding or a history of transient ischemic attack (TIA) or stroke [see Contraindications (4.1 , 4.2) ] . In patients ≥75 years of age, Effient is generally not recommended, because of the increased risk of fatal and intracranial bleeding and uncertain benefit, except in high-risk situations (patients with diabetes or a history of prior myocardial infarction [MI]) where its effect appears to be greater and its use may be considered [see Use in Specific Populations (8.5) ] . Do not start Effient in patients likely to undergo urgent coronary artery bypass graft surgery (CABG). When possible, discontinue Effient at least 7 days prior to any surgery [see Warnings and Precautions (5.2) ] . Additional risk factors for bleeding include: body weight <60 kg, propensity to bleed, concomitant use of medications that increase the risk of bleeding (e.g . , warfarin, heparin, fibrinolytic therapy, chronic use of nonsteroidal anti-inflammatory drugs [NSAIDs]) [see Warnings and Precautions (5.1) ] . Suspect bleeding in any patient who is hypotensive and has recently undergone coronary angiography, percutaneous coronary intervention (PCI), CABG, or other surgical procedures in the setting of Effient [see Warnings and Precautions (5.1) ] . If possible, manage bleeding without discontinuing Effient. Discontinuing Effient, particularly in the first few weeks after acute coronary syndrome, increases the risk of subsequent cardiovascular (CV) events [see Warnings and Precautions (5.3) ] . WARNING: BLEEDING RISK See full prescribing information for complete boxed warning. Effient can cause significant, sometimes fatal, bleeding ( 5.1 , 5.2 , 6.1 ). Do not use Effient in patients with active pathological bleeding or a history of transient ischemic attack or stroke ( 4.1 , 4.2 ). In p

How We Calculate These Metrics
Trial Activity Stage
Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.
Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.
- Growth: High proportion of early-phase trials (Phase 1/2), active development
- Expansion: Significant Phase 3 activity, approaching or pursuing approvals
- Mature: Substantial Phase 4 post-marketing studies
- Stable: Mixed phase distribution, steady development
- Declining: Low active trial ratio, reduced R&D investment
