Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Leuprolide, a GnRH agonist, suppresses pituitary gonadotropin release via receptor desensitization, reducing testicular and ovarian sex steroid production.
Leuprolide acetate, a GnRH agonist, initially stimulates pituitary gonadotropin release, but chronic administration suppresses LH and FSH secretion by downregulation of GnRH receptors, leading to reduced sex steroid production.
42 mg subcutaneously every 6 months.
Leuprolide acetate 3.75 mg IM monthly or 11.25 mg IM every 3 months; for central precocious puberty, 7.5 mg IM monthly or 22.5 mg IM every 3 months.

The terminal elimination half-life of leuprolide after subcutaneous administration is approximately 3 hours, with a range of 2.6 to 3.8 hours. This short half-life requires continuous delivery for sustained clinical effect.
Terminal elimination half-life is approximately 3 hours following subcutaneous administration; however, due to the depot formulation, the effective half-life is extended to about 1 month, driven by the slow release from the PLGA microspheres.
Leuprolide is primarily metabolized in the liver, and approximately 5% of the dose is excreted unchanged in urine. Less than 5% is excreted unchanged in feces via biliary elimination.
Renal (approximately 50% as unchanged drug and 50% as inactive metabolites); biliary/fecal excretion accounts for <5%
