Gonadotropin Releasing Hormone Analogue
Recommended dose of zoladex for prostate cancer 3 6 mg sc every 28 days or 10 8 mg sc every 12 weeks. All the gnrh agonists are very similar chemically but they come in different forms.

Gonadotropin releasing hormone gnrh is a hormone produced in the hypothalamus and transported to the pituitary gland through the blood stream.
Gonadotropin releasing hormone analogue. Gonadotropin releasing hormone gnrh antagonists are synthetic analogs of gonadotropin releasing hormone which is produced by the hypothalamus and controls the secretion of follicle stimulating hormone fsh and luteinizing hormone lh by the anterior pituitary. Gonadotropin releasing hormone gnrh is a releasing hormone responsible for the release of follicle stimulating hormone fsh and luteinizing hormone lh from the anterior pituitary gnrh is a tropic peptide hormone synthesized and released from gnrh neurons within the hypothalamus the peptide belongs to gonadotropin releasing hormone family it constitutes the initial step in the hypothalamic. Leuprorelin a gnrh agonist and gnrh analogue and a prototypical gnrh modulator.
Upon administration gnrh analog mimics endogenous gnrh and strongly binds to and activates pituitary gnrh receptors which stimulates the synthesis and secretion of the gonadotropic hormones follicle stimulating hormone fsh and luteinizing hormone lh. Firmagon degarelix lupaneta pack leuprolide acetate injection norethindrone acetate tablets lupron depot leuprolide acetate lupron depot ped leuprolide acetate supprelin la histrelin acetate trelstar triptorelin pamoate triptodur triptorelin vantas histrelin acetate zoladex goserelin acetate. Secretion of gnrh is controlled by neural input from other parts of the brain and in females particularly through negative feedback by the sex steroids.
A gnrh modulator or gnrh receptor modulator also known as an lhrh modulator or lhrh receptor modulator is a type of medication which modulates the gnrh receptor the biological target of the hypothalamic hormone gonadotropin releasing hormone gnrh. This policy refers to the following gonadotropin releasing hormone analog gnrh analog drug products. Gonadotrophin releasing hormone analogue.
A synthetic analog of the endogenous hormone gonadotropin releasing hormone gnrh with potential antineoplastic activity. Also known as luteinizing releasing hormone or lhrh. Center for drug evaluation and research this guidance describes the food and drug administration s fda s current recommendations regarding the overall development program to establish the.
Gnrh agonists are a group of drugs that have been used to treat women with endometriosis for over 20 years. They are modified versions of a naturally occurring hormone known as gonadotropin releasing hormone which helps to control the menstrual cycle. Gnrh controls the secretion of follicle stimulating hormone fsh and luteinizing hormone lh from the anterior pituitary.
Goserelin is available as zoladex in 3 6 mg sq injection given every 28 days and 10 8 mg sq injection given every 12 weeks. Zoladex is indicated for long term treatment unless clinically inappropriate. The gonadotropin releasing hormone gnrh agonists and antagonists are short peptide analogues of gnrh that cause a profound inhibition of estrogen and androgen synthesis and are used predominantly as androgen deprivation therapy of advanced prostate cancer.
Some of these agents are also used to treat benign conditions responsive to hormonal inhibition such as endometriosis uterine fibroids precocious puberty and infertility.
