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 is a synthetic gonadotropin-releasing hormone (GnRH) agonist. Upon continuous administration, it suppresses pituitary gonadotropin secretion by downregulating GnRH receptors, leading to decreased luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels, and consequently reducing sex steroid (testosterone and estrogen) production in the gonads.
42 mg subcutaneously every 6 months.
Prostate cancer: 7.5 mg IM once monthly or 22.5 mg IM once every 3 months or 45 mg SC once every 6 months. Central precocious puberty: 50 mcg/kg/day SC or 7.5 mg IM once monthly. Endometriosis: 3.75 mg IM once monthly or 11.25 mg IM once 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 intravenous administration; after subcutaneous depot formulations, the effective half-life is extended due to slow release, with a terminal half-life of about 3-4 weeks for the 1-month depot.
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 5% as unchanged drug; hepatic metabolism accounts for the majority of clearance, with metabolites excreted renally and fecally; biliary excretion is minimal.
