๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionAbsorbed orally; food increases absorption significantly (up to 10-fold).
DistributionHighly protein bound; distributes extensively into tissues.
Protein Binding>99% bound to plasma proteins (albumin and alpha-1 acid glycoprotein).
MetabolismMetabolized primarily by CYP3A4 and SULT2A1 to active metabolite abiraterone.
Half-LifeApproximately 12 hours (abiraterone).
ExcretionFecal (88%) and renal (5%) as metabolites.
BioavailabilityUnknown; food increases AUC by 10-fold.
Onset of ActionWithin 2-4 weeks for PSA decline.
Peak Plasma Time2 hours (fasted); 4-6 hours (fed).
Duration of ActionContinuous with daily dosing.

How It Works

Selectively inhibits CYP17A1 (17ฮฑ-hydroxylase/C17,20-lyase) in the adrenal glands and prostate cancer cells, blocking androgen synthesis.

Mechanism Steps

1Abiraterone acetate is hydrolyzed to abiraterone in the body.
2Abiraterone selectively and irreversibly inhibits CYP17A1 (17ฮฑ-hydroxylase/C17,20-lyase).
3Inhibition of 17ฮฑ-hydroxylase blocks conversion of pregnenolone to 17ฮฑ-hydroxypregnenolone.
