Kulo mhlahlandlela obanzi, sizohlola ukusetshenziswa kwamaphilisi e-finasteride kanye nemiphumela yawo emzimbeni. Sizohlola ukuthi i-oral finasteride isebenza kanjani, ukusebenzisana kwayo neminye imithi, kanye nolwazi olufanele lomthamo. 

Iyini i-Finasteride?

I-Finasteride umuthi onamandla okuyingxenye yezidakamizwa ezaziwa ngokuthi ama-5-alpha reductase inhibitors. Ithole ukuduma ngenxa yokuguquguquka kwayo ekwelapheni izimo zezokwelapha ezimbili ezihlukene: i-benign prostatic hyperplasia (BPH) kanye nokulahleka kwezinwele zephethini yabesilisa.

Kubalulekile ukuqaphela ukuthi nakuba i-finasteride izuzisa abaningi, ayifanele wonke umuntu. Ngakho-ke, amadoda kufanele axoxe ngezinzuzo ezingaba khona kanye nezingozi nodokotela wabo ngaphambi kokuqala ukwelashwa nge-finasteride.

Ukusetshenziswa kwethebhulethi ye-Finasteride

Amaphilisi e-Finasteride anokusetshenziswa okubili okuyinhloko ekwelashweni kwezokwelapha. Umuthi usebenza njengesixazululo esisebenzayo se-benign prostatic hyperplasia kanye ne-alopecia ye-androgenetic yabesilisa (i-MAA, ukulahleka kwezinwele zephethini yesilisa).

Kwabesilisa ababhekene ne-BPH, i-finasteride inikeza isisombululo sokuphatha izimpawu ze-prostate ekhulisiwe kanye nezinkinga ezivamile zomchamo. Lezi zinzuzo zihlanganisa ukuncipha kwesifiso sokuchama, ukugeleza komchamo okuthuthukisiwe, nomuzwa onciphile wokungapheleli kwesinye.

I-Finasteride isebenza njenge-inhibitor yokuncintisana yohlobo lwe-II kanye ne-III 5-alpha reductase enzymes. Ngokuvimbela lawa ma-enzyme, i-finasteride inciphisa ukuguqulwa kwe-testosterone ku-DHT. Lesi senzo siholela ekwehleni okukhulu kwamazinga e-DHT kuwo wonke umzimba.

Kwabesilisa abane-BPH, ukwehla kwamazinga e-hormone ye-DHT kubangela ukushwabana kwendlala yesinye. Lokhu kuncipha kosayizi, okungaba cishe ku-20-30% ngemva kwezinyanga ezingu-6-24 zokwelashwa okuqhubekayo, kusiza ekwehliseni izimpawu ezikhathazayo zomchamo ze-prostate ekhulisiwe.

Esimeni sokuba nempandla kwephethini yowesilisa, indlela yokusebenza ye-finasteride ifaka ukuncipha kokugxilisa kwe-DHT yekhanda lekhanda ukuya kumaleveli atholakala ezindaweni zekhanda ezisenezinwele. Lokhu kwehliswa kwe-DHT kunganciphisa ukulahleka kwezinwele futhi kukhulise nokukhula kabusha kwezinwele kwezinye izimo. 

Imiphumela ye-Finasteride iyabuyiseleka emuva. Uma umuthi usuyekiwe, amazinga e-DHT ngokuvamile abuyela kokujwayelekile phakathi namasonto amabili, futhi noma yiziphi izinzuzo ezitholwayo zizoncipha kancane kancane.
