Effect of testosterone administration on rates of ethanol elimination in hypogonadal patients

Research output: Contribution to journalArticlepeer-review


Rates of ethanol elimination were determined in four hypogonadal subjects at one week and again at eight weeks after the administration of one dose of 200 mg of testosterone cypionate (Depo-testosterone). Ethanol elimination was unchanged in two patients, slightly decreased in one, and markedly increased in one patient at eight weeks as compared to one week after testosterone administration. In the three patients with little or no change in ethanol elimination, initial high levels of plasma-free testosterone, ranging from 445.0 to 3.8 ng/dl did not decrease to abnormally low levels, but ranged between 1.6 and 7.7 ng/dl (normal, 1.20-2.10 ng/dl). In the fourth patient, an increase in ethanol elimination from 86.6 to 107.4 mg/kg body weight/hr was associated with a decrease in plasma-free testosterone from a high level of 4.7 to 0.8 ng/dl. These results indicate that pharmacological plasma concentration of testosterone do not affect the rate of ethanol elimination. A suppressing effect of testosterone on rate of ethanol elimination may occur at levels of plasma-free testosterone which extend from abnormally low up into the normal physiologic range.
