There is limited information available on the pharmacokinetics of oxymetholone.  It appears to be well-absorbed with oral administration .  Oxymetholone has very low affinity for human serum sex hormone-binding globulin (SHBG), less than 5% of that of testosterone and less than 1% of that of DHT.  The drug is metabolized in the liver by oxidation at the C2 position, reduction at the C3 position, hydroxylation at the C17 position, and conjugation .   The C2 hydroxymethylene group of oxymetholone can be cleaved to form mestanolone (17α-methyl-DHT), which may contribute to the effects of oxymetholone.  The elimination half-life of oxymetholone is unknown.  Oxymetholone and its metabolites are eliminated in the urine .
