I-Voxeletor - Ukusetshenziswa, Isilinganiso, Imiphumela Engemihle Nokunye

I-Voxeletor umuthi osetshenziswa kakhulu ukwelapha isifo se-sickle cell, isifo segazi esibangelwa ukukhiqizwa kwe-hemoglobin engajwayelekile, okuholela kumaseli abomvu egazi asontekile. Lo muthi omusha usebenza ngokwandisa ukusondelana kwe-hemoglobin nomoya-mpilo, ngaleyo ndlela unciphise ukugoba kwamaseli abomvu egazi futhi uthuthukise ukugeleza kwegazi jikelele. Ivunyiwe yi-FDA ngo-2019, i-Voxeletor imele intuthuko ebalulekile ekuphathweni kwesifo se-sickle cell, inikeza iziguli inketho entsha yokunciphisa izimpawu nokuthuthukisa ikhwalithi yempilo yazo.

Ukusetshenziswa kwe-Voxeletor

I-Voxeletor ihloselwe ngqo ukwelapha isifo se-sickle cell kubantu abadala kanye neziguli zezingane ezineminyaka engu-12 nangaphezulu. Isetshenziselwa ukunciphisa imvamisa yezinkinga ze-sickle cell, okuyizigameko ezibuhlungu ezibangelwa ukuvaleka kokugeleza kwegazi ngenxa yamaseli abomvu egazi abanjwe yi-sickle. Ngokubhekana nezinkinga eziyisisekelo ezihambisana nesifo se-sickle cell, i-Voxeletor isiza ukuphatha izimpawu futhi ithuthukise impilo kanye nenhlalakahle yeziguli iyonke.

Isebenza kanjani?

Indlela esebenza ngayo i-Voxeletor ilula kakhulu. Isebenza ngokubopha i-hemoglobin, iphrotheni esemaselini abomvu egazi ephethe ukuthwala umoya-mpilo emzimbeni wonke. Ngokubopha i-hemoglobin, i-Voxeletor yandisa ukusondela kwayo komoya-mpilo, okusiza ukugcina amaseli abomvu egazi esesimweni sawo esijwayelekile nesiyindilinga. Lokhu kunciphisa amathuba okuba amaseli aguqe futhi ahlangane ndawonye, ​​okungaholela ekuvinjweni okubuhlungu emithanjeni yegazi. Kalula nje, i-Voxeletor isiza ukugcina amaseli abomvu egazi ephilile futhi esebenza kahle, inciphisa izinkinga ezihambisana nesifo se-sickle cell.

Isilinganiso nokuphathwa

I-Voxeletor itholakala ngesimo sethebhulethi futhi ivame ukunikezwa ngomlomo. Umthamo ojwayelekile wabantu abadala kanye neziguli zezingane ezineminyaka engu-12 nangaphezulu u-1,500 mg (cishe u-30 mg/kg wezingane, noma amaphilisi ayisithupha angu-300 mg) athathwa kanye ngosuku. Kubalulekile ukuthatha i-Voxeletor kanye nokudla ukuze kuthuthukiswe ukumuncwa. Iziguli kufanele zilandele imiyalelo yomhlinzeki wazo wezempilo mayelana nomthamo kanye nokuphathwa ukuqinisekisa ukusebenza kahle kanye nokuphepha.

Imiphumela Engemihle ye-Voxeletor

Njengayo yonke imithi, i-Voxeletor ingabangela imiphumela emibi. Imiphumela emibi evamile ihlanganisa:

• bekhanda
• I-nausea
• Uhudo
• Ukukhathala
• Ubuhlungu besisu

Imiphumela emibi kakhulu, nakuba ingajwayelekile kakhulu, ingase ihlanganise:

• Ukusabela okukhulu kwe-allergic (ukuqubuka, ukulunywa, ukuvuvukala)
• Izinkinga zesibindi (eziboniswa ukuphuzi kwesikhumba noma amehlo)
• Ukusabela kwe-Hematologic (isb., i-priapism)

Iziguli kufanele zibike noma yimiphi imiphumela emibi engavamile noma enzima kumhlinzeki wazo wezempilo ngokushesha.

Ukusebenzisana kwezidakamizwa

I-Voxeletor ingasebenzisana nemithi ethile, okungathinta ukusebenza kwayo noma kwandise ingozi yemiphumela emibi. Ukusebenzisana okukhulu kwemithi kuhlanganisa:

• Ama-inducer aqinile e-CYP3A4 (isb., i-rifampin) anciphisa ukusebenza kahle, kanti ama-inhibitor anamandla/ama-inducer aphakathi nendawo (isb., i-ritonavir, i-fluconazole) adinga ukulungiswa komthamo.
• Izidambisigciwane (isb, ritonavir)
• Ama-antifungal (isb., i-fluconazole)
• Ama-antibiotic athile

Iziguli kufanele zazise umhlinzeki wazo wezempilo ngayo yonke imithi, izithasiselo, kanye nemikhiqizo yamakhambi abayisebenzisayo ukuze bagweme ukusebenzisana okungenzeka.

Izinzuzo ze-Voxeletor

Izinzuzo zezokwelapha ze-Voxeletor zifaka:

• Ukuncipha kokuvama kwezinkinga ze-sickle cell
• Ukuthuthukiswa kwamazinga e-hemoglobin
• Ikhwalithi yokuphila ethuthukisiwe yeziguli ezinesifo se-sickle cell
• Ukuphathwa ngomlomo, okwenza kube lula ngeziguli ukuthatha uma kuqhathaniswa nokwelashwa okujovwayo

Lezi zinzuzo zenza i-Voxeletor ibe yindlela ebalulekile ekuphathweni kwesifo se-sickle cell.

Ukuphikisana kwe-Voxeletor

I-Voxeletor ayivunyelwe kubantu abathile. Abantu abanolwazi lokuzwela i-Voxeletor noma ezinye izingxenye zayo kufanele bagweme lo muthi. Qaphela ezigulini ezinokukhubazeka kwesibindi okumaphakathi noma okukhulu (nciphisa umthamo); akukhuthazwa ezimweni ezinzima ngaphandle kokuqapha.

Ukuqapha Nezexwayiso

Ngaphambi kokuqala i-Voxeletor, iziguli kufanele zihlolwe ngokuphelele, okuhlanganisa nokuhlolwa kokusebenza kwesibindi, zigweme ama-inducer aqinile e-CYP3A, futhi ziqaphe ukuqubuka (ukuzwela okukhulu). Ukuyekisa kungaholela ekuweni kwe-hemoglobin, ukuqinisekisa ukuphepha. Kubalulekile ukuqapha amazinga e-hemoglobin njalo ngesikhathi sokwelashwa ukuze kugwenywe izinkinga. Abesifazane abakhulelwe noma abancelisayo kufanele baxoxe ngezingozi nezinzuzo ze-Voxeletor nomhlinzeki wabo wezempilo, njengoba imiphumela ekukhuleni kwengane kanye nezinsana ezincelisayo ingaqondwa ngokugcwele.
