4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

The substance can be absorbed into the body by inhalation and by ingestion.

Following oral admin ... to rabbits, cmpd is excreted in urine in conjugation with sulfuric & glucuronic acids. Similar results were obtained when animals were subjected to repeated inhalation of cmpd.

... Rabbits exposed to lowest concn ... 145 ppm cyclohexanol in air, showed no incr in conjugation of urinary sulfates but excreted 5 times normal amt glucuronic acid.

4.2 Metabolism/Metabolites

Cyclohexane was hydroxylated to cyclohexanol by rat liver microsomes in presence of NADPH & oxygen. Pretreatment with phenobarbital at 80 mg/kg/day ip stimulated activity 6-fold, while benzopyrene pretreatment at 20 mg/kg ip lowered cyclohexane hydroxylation.

PMID:4388853 ULLRICH V; HOPPE-SEYLER'S Z PHYSIOL CHEM 350 (3): 357 (1969)


Cyclohexanol was identified as the urinary metabolite after admin of cyclohexylamine hydrochloride to rats, rabbits, & guinea pigs (50-500 mg/kg, orally or ip) and humans (25 or 200 mg, orally).

Fed to rabbits, /cyclohexanol/ ... Is mostly excreted as the glucuronide conjugate (60% of the dose), but a small amt is oxidized further into trans-cyclohexane-1,2-diol (6%).
