- Contraindications & Blackbox Warnings
Contraindications & Blackbox WarningsWith our commercial data, access important information on dangerous risks, contraindications, and adverse effects.Our Blackbox Warnings cover Risks, Contraindications, and Adverse Effects- Pharmacodynamics
Resitance to enzalutamide therapy has been observed. This may occurred due to an upregulation of NF-κB2/p52.
- Mechanism of action
Enzalutamide is a competitive androgen receptor inhibitor that effects multiple stages of the signalling pathway. It is able to inhibit androgen binding to its receptor, androgen receptor nuclear translocation, and subsequent interaction with DNA. As a result, proliferation of prostate cancer cells decreases which ultimately leads to apoptosis and decreased tumour volume.
Target Actions Organism AAndrogen receptor inhibitorHumans - Absorption
The pharmacokinetic profile of enzalutamide and N-desmethyl enzalutamide (its major active metabolite) is described by a linear two-compartment model with first-order absorption. Enzalutamide also accumulates. Food does not affect its absorption. Tmax, prostate cancer patients = 1 hour (range of 0.5-3 hours); Cmax, steady state, enzalutamide = 16.6 μg/mL; Cmax, steady state, N-desmethyl enzalutamide = 12.7 μg/mL; Time to steady state, daily dosing = 28 days;
- Volume of distribution
Apparent volume of distribution (Vd/F), single oral dose = 110 L
- Protein binding
Enzalutamide is 97% to 98% bound to plasma proteins, primarily albumin. N-desmethyl enzalutamide is 95% bound to plasma proteins.
- Metabolism
Enzalutamide is hepatically metabolized, primarily by CYP2C8 and CYP3A4. The enzyme that converts enzalutamide to its active metabolite, N-desmethyl enzalutamide, is CYP2C8. The activity of N-desmethyl-enzalutamide is similar to that of the parent compound.
- Route of elimination
Enzalutamide is primarily eliminated by hepatic metabolism. 71% of the dose is recovered in urine (including only trace amounts of enzalutamide and N-desmethyl enzalutamide), and 14% is recovered in feces (0.4% of dose as unchanged enzalutamide and 1% as N-desmethyl enzalutamide).
- Half-life
The mean terminal half-life (t1/2) for enzalutamide in patients after a single oral dose is 5.8 days (range 2.8 to 10.2 days). Following a single 160 mg oral dose of enzalutamide in healthy volunteers, the mean terminal t1/2 for N-desmethyl enzalutamide is approximately 7.8 to 8.6 days.
- Clearance
Apparent clearance (CL/F), single oral dose = 0.56 L/h (range of 0.33 - 1.02 L/h)
