CAMCEVI ETM vs LUPRON DEPOT-PED KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Leuprolide is a GnRH agonist that inhibits pituitary gonadotropin secretion, leading to suppression of testicular and ovarian steroidogenesis.
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.
21 mg subcutaneously once 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 CAMCEVI after subcutaneous administration is approximately 3 hours. This short half-life reflects rapid clearance; however, the clinical duration of action is prolonged due to the depot formulation providing continuous release over 6 months.
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.
Following subcutaneous injection, CAMCEVI (leuprolide) is primarily eliminated via renal excretion. Approximately 90% of a leuprolide dose is recovered in urine as parent drug and metabolite fractions, with 5% excreted in feces via biliary elimination.
Renal (approximately 50% as unchanged drug and 50% as inactive metabolites); biliary/fecal excretion accounts for <5%
