Izixhobo ezithengiswa kakhulu kwiRitonavir Anti-Virus
Inkcazo eneenkcukacha
I-Ritonavir, iyeza le-antiretroviral, liqhele ukusetyenziswa ngokudityaniswa namanye amayeza ukunyanga i-HIV/AIDS. Olu nyango ludityanisiweyo, olwaziwa njengonyango olusebenzayo lwe-antiretroviral (HAART), lubonakalise ukusebenza ngempumelelo ekulawuleni imeko. I-Ritonavir ihlelwa njenge-protease inhibitor, kodwa umsebenzi wayo ophambili ngoku kukunyusa amandla ezinye ii-protease inhibitors.
Ukongeza kusetyenziso lwayo kunyango lwe-HIV/AIDS, i-ritonavir ikwasetyenziswe ngokudibeneyo namanye amayeza ukunyanga i-hepatitis C kwaye, kutsha nje, i-COVID-19. Ithathwa ngomlomo ngendlela yeepilisi okanye iipilisi. Kubalulekile ukuqaphela ukuba i-bioavailability ye-ritonavir tablets kunye ne-capsules zinokwahluka, kunye neepilisi ezinokukhokelela kwincopho ephezulu ye-plasma concentrations.I-Ritonavir isebenza njenge-inhibitor ye-HIV protease enzyme, iphazamisa umjikelo wokuzala wentsholongwane. Nangona ekuqaleni yaphuhliswa njenge-agent ye-antiviral ezimeleyo, ibonise iimpawu eziluncedo ngakumbi xa isetyenziswe kwiirejimeni ezidityanisiweyo ezinedosi ephantsi ye-ritonavir kunye nezinye ii-protease inhibitors. Namhlanje, isetyenziswa kakhulu njenge-booster yezinye ii-protease inhibitors. Ifumaneka kuzo zombini ulwelo kunye ne-capsules.
Esona sicelo siphambili se-ritonavir sikunyango lwezigulane ezine-HIV, ingakumbi i-Type 1, elona xinzelelo luyingozi kakhulu kunye noluxhaphakileyo. Idla ngokudityaniswa nelinye iyeza le-antiretroviral elibizwa ngokuba yi-lopinavir ukunyusa ukusebenza konyango. I-Lopinavir kunye ne-ritonavir zisebenza kunye ukuthintela kunye nokunciphisa ukuveliswa kwentsholongwane kaGawulayo emzimbeni. Nangona kunjalo, kubalulekile ukuqonda ukuba i-lopinavir kunye ne-ritonavir ayilonyango lwe-HIV kwaye ayikuthinteli usulelo lwentsholongwane ukusuka komnye umntu ukuya komnye.
Xa isetyenziswe kunye namanye amayeza e-HIV, i-ritonavir inceda ukulawula usulelo lwe-HIV ngokunciphisa umthamo we-HIV emzimbeni. Oku, kwakhona, kuphucula ukusebenza kwe-immune system, ukunciphisa umngcipheko weengxaki kunye nokuphucula umgangatho wobomi bonke. I-Ritonavir yeyodidi lwe-protease inhibitors kwaye isebenza ngokwandisa amanqanaba ezinye ii-protease inhibitors, ngaloo ndlela iphucula ukusebenza kwazo. Kubalulekile ukuba izigulane zazi ukuba i-ritonavir ayilunyangi usulelo lwe-HIV. Ukunciphisa ingozi yokosulela isifo, kubalulekile ukubambelela kwirejimeni emiselweyo yamayeza e-HIV. Ukongeza, ukusebenzisa iindlela ezisebenzayo zesithintelo ezinje nge latex okanye iikhondom zepolyurethane ngexesha lomsebenzi wesondo kunye nokunqanda ukwabelana ngezinto zobuqu ezinokuthi zidibane negazi okanye ulwelo lomzimba ngamanyathelo okhuseleko abalulekileyo ekufuneka uwathathe.
Yayiphuhliswe ekuqaleni njenge-inhibitor ye-HIV protease, i-ritonavir ngoku ayifane isetyenziselwe umsebenzi wayo wokuthomalalisa iintsholongwane. Endaweni yoko, isetyenziswa ngokubanzi njenge-booster yezinye ii-protease inhibitors. I-Ritonavir inqanda i-enzyme eyaziwa ngokuba yi-cytochrome P450-3A4 (CYP3A4), ejongene ne-metabolizing protease inhibitors. Ngokuzibophelela kunye nokuvimbela i-CYP3A4, i-ritonavir yenza ukuba kusetyenziswe iidosi eziphantsi kwezinye ii-protease inhibitors, ukuphucula ukusebenza kwazo kunye nokunciphisa iziphumo ezibi. Nangona kunjalo, kubalulekile ukuqaphela ukuba inhibition ye-CYP3A4 inokuchaphazela ukusebenza kwamanye amayeza, ibeka imingeni xa ichaza iziyobisi ngaxeshanye.
Ngamafutshane, i-ritonavir licandelo elibalulekileyo lonyango lwe-HIV/AIDS, esebenza njenge-protease inhibitor kunye ne-booster yezinye ii-protease inhibitors. Olona setyenziso lwayo luphambili kunyango lwe-HIV, ngakumbi i-Type 1. Ngelixa inceda ekulawuleni usulelo lwe-HIV kwaye iphucula umgangatho wobomi, ayilonyango kwaye ayikuthinteli usulelo lwentsholongwane. Ukuqonda umsebenzi wamayeza kunye nokubambelela kwiirejimeni zonyango ezimiselweyo kubalulekile ekulawuleni ngempumelelo imeko.
