Identification
- Summary
Prasugrel is a P2Y12 platelet inhibitor used to reduce risk of thrombotic cardiovascular events in unstable angina or non-ST-elevation myocardial infarction (NSTEMI), and in patients with STEMI when managed with either primary or delayed PCI.
- Brand Names
- Effient, Efient
- Generic Name
- Prasugrel
- DrugBank Accession Number
- DB06209
- Background
Prasugrel, a thienopyridine derivative, is a platelet activation and aggregation inhibitor structurally and pharmacologically related to clopidogrel and ticlopidine. Similar to clopidogrel, prasugrel is a prodrug that requires enzymatic transformation in the liver to its active metabolite, R-138727. R-138727 irreversibly binds to P2Y12 type ADP receptors on platelets thus preventing activation of the GPIIb/IIIa receptor complex. As a result, inhibition of ADP-mediated platelet activation and aggregation occurs. Prasugrel was developed by Daiichi Sankyo Co. and is currently marketed in the United States and Canada in cooperation with Eli Lilly and Company for acute coronary syndromes planned for percutaneous coronary intervention (PCI). FDA approved in 2009.

Pharmacology
- Indication
Indicated in combination with acetylsalicylic acid (ASA) to prevent atherothrombotic events in patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI). May be used in patients with unstable angina (UA), non-ST elevation myocardial infarction (NSTEMI), ST-elevation myocardial infarction (STEMI) who are to be managed with PCI. Prasugrel is not recommended in patients 75 years of age or greater, those that weigh<60kg, and patients with a history of stroke or transient ischemic attack due to increased risk of fatal and intracranial bleeding.

Prasugrel is a thienopyridine ADP receptor inhibitors which inhibits platelet aggregation by irreversibly binding to P2Y12 receptors.
- Mechanism of action
Prasugrel is an thienopyridine and a prodrug which inhibits ADP receptors by irreversibly acting on the P2Y12 receptor on platelets. The active metabolite of prasugrel prevents binding of adenosine diphosphate (ADP) to its platelet receptor, impairing the ADP-mediated activation of the glycoprotein GPIIb/IIIa complex. Prasugrel is proposed to have a similar mechanism of action to clopidogrel.
Target Actions Organism AP2Y purinoceptor 12 antagonistHumans - Absorption
79% or greater of the dose is absorbed after oral administration. Absorption and metabolism occur rapidly and peak plasma concentrations (Cmax) are reached approximately 30 minutes following oral administration. Administration with a high fat, high calorie meal did not affect the AUC of the active metabolite in healthy individuals, but the Cmax was decreased by ~49% and the Tmax was increased to 0.5 to 1.5 hours. Prasugrel may be administered with or without food.
- Volume of distribution
44-68L
- Protein binding
Approximately 98% of the active metabolite was bound to human serum albumin in a 4% buffered solution. The major inactive metabolites are also highly bound to human plasma proteins.
- Metabolism
Prasugrel is not detected in plasma following oral administration. It is rapidly hydrolyzed in the intestine to thiolactone by human carboxylesterase (hCE) 2. This intermediate is further metabolized to its active metabolite, R-138727, in a single step by cytochrome P450 enzymes in the liver (primarily CYP3A4 and CYP2B6 and to a lesser extent by CYP2C9 and CYP2C19). The active metabolite is further metabolized by S-methylation or cysteine conjugation to two inactive metabolites.
Unlike clopidogrel, transformation of prasugrel to its active metabolite does not appear to be affected by cytochrome P450 polymorphisms.

- Route of elimination
Approximately 68% of the orally administered dose is excreted in urine and 27% in the feces, as inactive metabolites. The active metabolite is not expected to be removed by dialysis.
- Half-life
The active metabolite has an elimination half-life of about 7.4 hours (range 2-15 hours).
- Clearance
Apparent clearance = 112 - 166 L/hr

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Abacavir may decrease the excretion rate of Prasugrel which could result in a higher serum level. Abametapir The serum concentration of Prasugrel can be increased when it is combined with Abametapir. Abatacept The metabolism of Prasugrel can be increased when combined with Abatacept. Abciximab The risk or severity of bleeding can be increased when Abciximab is combined with Prasugrel. Abrocitinib The risk or severity of bleeding and thrombocytopenia can be increased when Prasugrel is combined with Abrocitinib. - Food Interactions

Plays a role in the metabolism of androgens, particularly in oxidative deactivation of testosterone (PubMed:15373842, PubMed:15764715, PubMed:22773874, PubMed:2732228). Metabolizes testosterone to less biologically active 2beta- and 6beta-hydroxytestosterones (PubMed:15373842, PubMed:15764715, PubMed:2732228). Contributes to the formation of hydroxycholesterols (oxysterols), particularly A-ring hydroxylated cholesterol at the C-4beta position, and side chain hydroxylated cholesterol at the C-25 position, likely contributing to cholesterol degradation and bile acid biosynthesis (PubMed:21576599). Catalyzes bisallylic hydroxylation of polyunsaturated fatty acids (PUFA) (PubMed:9435160). Catalyzes the epoxidation of double bonds of PUFA with a preference for the last double bond (PubMed:19965576). Metabolizes endocannabinoid arachidonoylethanolamide (anandamide) to 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling (PubMed:20702771). Plays a role in the metabolism of retinoids. Displays high catalytic activity for oxidation of all-trans-retinol to all-trans-retinal, a rate-limiting step for the biosynthesis of all-trans-retinoic acid (atRA) (PubMed:10681376). Further metabolizes atRA toward 4-hydroxyretinoate and may play a role in hepatic atRA clearance (PubMed:11093772). Responsible for oxidative metabolism of xenobiotics. Acts as a 2-exo-monooxygenase for plant lipid 1,8-cineole (eucalyptol) (PubMed:11159812). Metabolizes the majority of the administered drugs. Catalyzes sulfoxidation of the anthelmintics albendazole and fenbendazole (PubMed:10759686). Hydroxylates antimalarial drug quinine (PubMed:8968357). Acts as a 1,4-cineole 2-exo-monooxygenase (PubMed:11695850). Also involved in vitamin D catabolism and calcium homeostasis.

- A cytochrome P450 monooxygenase involved in the metabolism of polyunsaturated fatty acids (PUFA) (PubMed:18577768, PubMed:19965576, PubMed:20972997). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase) (PubMed:18577768, PubMed:19965576, PubMed:20972997). Catalyzes the hydroxylation of carbon-hydrogen bonds. Hydroxylates PUFA specifically at the omega-1 position (PubMed:18577768). Catalyzes the epoxidation of double bonds of PUFA (PubMed:19965576, PubMed:20972997). Also metabolizes plant monoterpenes such as limonene. Oxygenates (R)- and (S)-limonene to produce carveol and perillyl alcohol (PubMed:11950794). Responsible for the metabolism of a number of therapeutic agents such as the anticonvulsant drug S-mephenytoin, omeprazole, proguanil, certain barbiturates, diazepam, propranolol, citalopram and imipramine. Hydroxylates fenbendazole at the 4' position (PubMed:23959307)

- General Function
- Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (PubMed:19021548). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed:6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed:6234017)
