Abarelix onamandla Gonadotropin-Ukukhupha iHormone Antagonist for Prostate Cancer Treatment
Inkcazo eneenkcukacha
I-Abarelix, i-synthetic decapeptide, ibonisa umsebenzi onamandla ochasayo ngokuchasene ne-gonadotropin-releasing hormone (GnRH). Ngokuyintloko isetyenziselwa ukunyanga abaguli abanomhlaza wesifo se-prostate ophezulu abangabaviwa abafanelekileyo kwi-luteinizing hormone-releasing hormone agonists okanye i-castration yotyando. Ngokuthintela ngokuthe ngqo ukukhutshwa kwehomoni ye-luteinizing (LH) kunye ne-follicle-stimulating hormone (FSH), i-abarelix iyanciphisa ngokufanelekileyo ukuveliswa kwe-testosterone kumasende. masiphonononge izalathiso zonyango, iindlela zokwenza, kunye nokusetyenziswa kwe-abarelix.
I-Abarelix iboniswe kunyango lwe-palliative yezigulane ezineempawu ezinomdlavuza we-prostate ogqithiseleyo ohlangabezana neendlela ezithile. Kunconywa kwizigulane ezingabaviwa abafanelekileyo kwi-luteinizing hormone-releasing hormone agonists, ukwenqaba ukuchithwa kokuhlinzwa, kunye neengozi ezongezelelweyo ezifana nomonakalo we-neurological ngenxa ye-metastasis, i-ureter okanye i-bladder orifice obstruction ebangelwa ukuguguleka kwendawo okanye i-metastasis, okanye iintlungu ezibuhlungu zethambo ze-metastatic ezifuna ukukhululeka kweentlungu eziqhubekayo.
Njengomchasi otofwayo we-gonadotropin-ekhupha ihomoni (umchasi we-GnRH), i-abarelix idlala indima ebalulekileyo ekunciphiseni imveliso ye-testosterone kwizigulana ezinomhlaza wedlala lesidoda esineempawu eziphambili xa ezinye iindlela zonyango zilinganiselwe. Ithintela ngokuthe ngqo ukukhutshwa kwe-LH kunye ne-FSH, ethi emva koko inciphise ukukhululwa kwe testosterone kumasende. Ngokuvimba iiseli zomhlaza wedlala lesidoda kwi-testosterone, i-abarelix inceda kulawulo lwesi sifo kunye nokunciphisa iimpawu ezinxulumeneyo.
Ukusetyenziswa kwe-abarelix kunyango lomhlaza wedlala lesidoda kubonelela ngeyona ndlela ibalulekileyo kwizigulana ezingakwaziyo ukutyhubela okanye ukwala ukuthenwa ngotyando okanye olunye unyango lwehomoni. Ukukwazi kwayo ukuchasa i-GnRH kunye nokucinezela imveliso ye testosterone inika isiqabu kwaye inceda ukulawula ukuqhubeka kwesi sifo. Ngokunciphisa amanqanaba e-testosterone, i-abarelix inceda ekuthinteleni ukukhula kunye nokwanda kweeseli zomhlaza wesibeleko, ngaloo ndlela ibonelela ngesiqabu seempawu kunye nokuphucula umgangatho wobomi besigulana.
U-Abarelix, umchasi onamandla we-gonadotropin-ekhulula ihomoni, lukhetho oluxabisekileyo lonyango kwizigulana ezinomhlaza we-prostate oneempawu eziphambili ezingabaviwa abafanelekileyo kwi-luteinizing ihomoni ekhupha i-agonists okanye i-castration yotyando. Ngokuthintela ngokuthe ngqo ukukhutshwa kwe-LH kunye ne-FSH, i-abarelix inciphisa ngokufanelekileyo imveliso ye-testosterone, ebalulekileyo ekukhuleni nasekuqhubeleni phambili komhlaza wedlala lesinyi. Ukusetyenziswa kwayo kubonelela ngesiqabu sokudambisa kwaye inceda ukulawula isifo kwizigulana ezinokhetho olunyiniweyo lonyango. I-Abarelix, ithengiswa njenge-Plenaxis, isebenza njengesixhobo esibalulekileyo ekulweni nomhlaza we-prostate ophezulu, igalelo ekuphuculeni iziphumo zesigulane kunye nokuphucula umgangatho wobomi.
