Wide distribution in rat QWBA; crosses blood-brain and testis barriers; no melanin binding
“As pigmented and non-pigmented skins were comparably labelled, it is concluded that there is no melanin binding. Radioactivity was found to cross the testis, and blood-brain barrier, and exposure was about 2-fold lower than in blood.”
Major human metabolites M2 and M47 (~25% each of circulating drug-related material) not covered in animals
“In humans, two metabolites, M2 (oxy-dehydro-ganaxolone) and M47 (a ganaxolone sulfate conjugate), have been identified as major metabolites, each accounting for approximately 25% of total circulating drug-related material.”
