Pharmacology:

Endogenous androgens, including testosterone and dihydrotestosterone, are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics.

Male hypogonadism results from insufficient secretion of testosterone and is characterized by low serum testosterone concentrations. Signs/symptoms associated with male hypogonadism include erectile dysfunction and decreased ­sexual desire, fatigue and loss of energy, mood depression, regression of secondary sexual characteristics and osteoporosis. Male hypogonadism has two main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelter’s Syndrome or Leydig cell aplasia, whereas secondary hypogonadism is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).

Axiron is a clear, colorless, single phase solution containing 30mg of testosterone in 1.5mL of solution for topical administration through the axilla. In general, steady-state serum concentrations are achieved by approximately 14 days of daily dosing.

May increase dose in 30mg increments if serum testosterone <300ng/dL up to 120mg; reduce dose to 30mg if levels >1050ng/dL, discontinue if serum testosterone remains >1050ng/dL.
