Tác dụng
Description:
Mechanism of Action: Cetrorelix, a synthetic gonadorelin or gonadotropin releasing hormone (GnRH) analogue, is a competitive antagonist of naturally-occurring GnRH for binding on anterior pituitary receptors. This delays premature luteinising hormone (LH) surge, thereby suppressing ovulation, oocytic meiosis, and luteinisation. Onset: 2 hr. Duration: 24 hr. Pharmacokinetics: Absorption: Rapidly absorbed. Bioavailability: Approx 85%. Time to peak plasma concentration: 1-2 hr. Distribution: Volume of distribution: Approx 1 L/kg. Plasma protein binding: 86%. Metabolism: Metabolised by peptidases, predominantly into (1-4) peptide and into (1-9), (1-7), and (1-6) peptides. Excretion: Via faeces (5-10% as unchanged drug and metabolites) and urine (2-4% as unchanged drug). Terminal elimination half-life: 30 hr. |
