What this means
- 01
Health Canada has approved Triptorelin for at least one labeled indication, so a pharmaceutical-grade product exists in Canada and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Triptorelin is
A decapeptide GnRH agonist approved in the United States in 2000 for advanced prostate cancer and in 2017 for central precocious puberty. In a pooled analysis of 920 men, 91 to 93 percent held testosterone below 20 ng/dL from month 3 onward. It causes a testosterone flare in the first days of treatment, which is the clinical reason the antagonists exist.
Triptorelin is a synthetic ten-amino-acid analogue of gonadotrophin-releasing hormone, the hypothalamic signal that drives the pituitary to release luteinising hormone and follicle-stimulating hormone. It is an agonist, which sounds like it should raise sex hormones and briefly does, before shutting the axis down.
Mechanism: Continuous rather than pulsatile occupancy of the GnRH receptor on pituitary gonadotrophs. Physiological GnRH arrives in pulses, and the receptor requires that rhythm to keep signalling.
Regulatory history: FDA-approved. Trelstar under NDA 020715 on 15 June 2000 for palliative treatment of advanced prostate cancer, with additional formulations approved in 2001 and 2010. Triptodur under NDA 208956 on 29 June 2017 for central precocious puberty in children aged two and older. Not approved in the United States for endometriosis, for fertility protocols, or for any use in healthy adults.
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Triptorelin at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
