MedKoo Cat#: 100105 | Name: Buserelin

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Buserelin is a Gonadotropin-releasing hormone agonist (GnRH agonist). The drug's effects are dependent on the frequency and time course of administration. GnRH is released in a pulsatile fashion in the postpubertal adult. Initial interaction of any GnRH agonist, such as buserelin, with the GnRH receptor induces release of FSH and LH by gonadotrophes.

More Info
Buserelin is a synthetic analog of gonadotropin-releasing hormone (GnRH). Buserelin binds to and activates pituitary gonadotropin releasing hormone (GnRH) receptors. Prolonged administration of buserelin results in sustained inhibition of gonadotropin production, suppression of testicular and ovarian steroidogenesis, and reduced levels of circulating gonadotropin and gonadal steroids. Buserelin is more potent that GnRH. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
