The active ingredient leuprorelin, like goserelin, is a synthetic peptide that can be used primarily in the treatment of hormone-dependent tumors, particularly prostate cancer. Administration of leuprorelin has indirect effects on testosterone levels in men, the lowering of which stops the growth of malignant cancerous tumors. Leuprorelin is administered in the form of a biodegradable implant that releases the active ingredient over a three-month period (11.25 mg dosage). Leuprorelin is the only implant formulation with a self-retracting needle, which makes administration much more convenient for patients.
