Drugs in this class can also cause retention of nitrogen, sodium, potassium, phosphorus, and decreased urinary excretion of calcium.
Androgens have been reported to increase protein anabolism and decrease protein catabolism.
Nitrogen balance is improved only when there is sufficient intake of calories and protein.
