Pharmacology

Mechanism of Action: Psilocybin is a prodrug for psilocin, which acts as a partial agonist at serotonin 5-HT2A receptors, similar to other classical psychedelics.

Metabolism: Metabolized in the liver by alkaline phosphatase to form psilocin, which is then further metabolized by CYP2D6 and CYP3A4 enzymes.

Half-life: Approximately 2-3 hours, with effects typically lasting 4-8 hours.

Bioavailability: ~70% when taken orally, with peak plasma concentrations reached within 1-2 hours.
