I-Ustekinumab - Ukusetshenziswa, Isilinganiso, Imiphumela Engemihle Nokunye Okuningi

Isingeniso: Kuyini i-Ustekinumab?

I-Ustekinumab umuthi we-biologic osetshenziswa kakhulu ekwelapheni izimo zokuzivikela komzimba ezifana ne-psoriasis, i-psoriatic arthritis, isifo sikaCrohn, kanye ne-ulcerative colitis. I-antibody ye-monoclonal ehlasela amaprotheni athile ohlelweni lokuzivikela komzimba, esiza ekunciphiseni ukuvuvukala nokuphatha izimpawu ezihambisana nalezi zimo ezingamahlalakhona. Yavunywa yi-FDA ngo-2009, i-Ustekinumab isibe yindlela ebalulekile yeziguli ezifuna impumuzo emiphumeleni elimazayo yalezi zifo.

Ukusetshenziswa kwe-Ustekinumab

I-Ustekinumab ivunyelwe ukusetshenziswa kwezokwelapha eziningana, okuhlanganisa:

• I-Psoriasis ye-Plaque: I-Ustekinumab isetshenziselwa ukwelapha i-plaque psoriasis ephakathi kuya kwenzima kubantu abadala nezingane ezineminyaka engu-12 nangaphezulu ezifuna ukwelashwa nge-phototherapy noma ukwelashwa ngesistimu. Iyasiza ekuhlanzeni isikhumba futhi inciphise ubukhali besifo.
• I-Psoriatic Arthritis: Lo muthi unikezwa abantu abadala abaneminyaka engu-18 nangaphezulu abane-arthritis esebenzayo ye-psoriatic, kungaba yodwa noma ihlanganiswe nezinye izindlela zokwelapha, ukusiza ekunciphiseni ubuhlungu bamalunga nokuvuvukala.
• Isifo sikaCrohn: I-Ustekinumab ivunyelwe futhi ekwelapheni isifo sikaCrohn esimaphakathi kuya kwesibi kubantu abadala abangasabelanga kahle kwezinye izindlela zokwelapha. Iyasiza ekunciphiseni ukuvuvukala endleleni yokugaya ukudla.
• I-Ulcerative Colitis: I-Ustekinumab ivunyelwe ukwelapha i-ulcerative colitis esebenzayo ngokulingene kuya kakhulu kubantu abadala.

Isebenza kanjani?

I-Ustekinumab isebenza ngokugxila nokuvimbela amaprotheni athile ohlelweni lokuzivikela komzimba olwaziwa ngokuthi "i-interleukin-12 (IL-12) kanye ne-interleukin-23 (IL-23). ​​Lawa maprotheni adlala indima ebalulekile enkambisweni yokuvuvukala eholela ezimpawini zezifo ezizimele. Ngokuvimba la maprotheni, i-Ustekinumab isiza ukunciphisa ukuvuvukala, ukunciphisa impendulo yokuzivikela komzimba, futhi ekugcineni ithuthukise izimpawu ezihambisana nezimo ezifana ne-psoriasis nesifo sikaCrohn.

Isilinganiso nokuphathwa

I-Ustekinumab inikezwa ngomjovo. Umthamo ojwayelekile wabantu abadala uyahlukahluka kuye ngesimo eselashwayo:

• I-Psoriasis ye-Plaque: Umthamo wokuqala usekelwe esisindweni: 45 mg (?100 kg) noma 90 mg (>100 kg), kulandele umthamo wesibili ngemva kwamasonto ama-4. Imithamo yokunakekela inikezwa njalo emavikini ayi-12.
• I-Psoriatic Arthritis: Umthamo wokuqala usekelwe esisindweni: 45 mg (?100 kg) noma 90 mg (>100 kg), kanye nomthamo wesibili ngemva kwamasonto ama-4. Imithamo yokunakekela nayo inikezwa njalo emavikini ayi-12.
• Isifo sikaCrohn: Umthamo wokungeniswa kwe-intravenous (IV) owodwa ongu-260 mg, kulandele i-subcutaneous (SC) engu-90 mg ngesonto lesi-8, bese kuba njalo emavikini ayi-8.

Ezinganeni ezigulayo (i-psoriasis kuphela, iminyaka engu-?6), umthamo usekelwe esisindweni se-SC futhi kufanele unqunywe ngumhlinzeki wezempilo.

Imiphumela Engemihle ye-Ustekinumab

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

• Ukusabela kwendawo yomjovo (ubomvu, ukuvuvukala, ubuhlungu)
• bekhanda
• Ukukhathala
• I-nausea

Imiphumela emibi kakhulu ingase ihlanganise:

• Ingozi eyengeziwe yokutheleleka (ngenxa yokucindezelwa kwamasosha omzimba)
• Ukungezwani komzimba (ukuqubuka, ukulunywa, ukuvuvukala)
• Izinkinga zesibindi (ama-enzyme esibindi aphezulu)
• Imibiko engavamile yezifo ezibangelwa umdlavuza (ukuqapha isikhathi eside)
• I-Reversible posterior leukoencephalopathy syndrome (RPLS)

Iziguli kufanele zibike noma yiziphi izimpawu ezingavamile kumhlinzeki wazo wezempilo ngokushesha.

Ukusebenzisana kwezidakamizwa

I-Ustekinumab ingasebenzisana neminye imithi, okungathinta ukusebenza kwayo noma kwandise ingozi yemiphumela emibi. Ukusebenzisana okukhulu kwemithi kuhlanganisa:

• Ama-Immunosuppressants: Ukuhlanganisa i-Ustekinumab neminye imithi yokucindezela amasosha omzimba kungandisa ingozi yokutheleleka.
• Imithi Yokugoma Ephilayo: Iziguli kufanele zigweme imijovo ephilayo ngenkathi zisebenzisa i-Ustekinumab, njengoba impendulo yomzimba ingase ibe buthaka.

Njalo yazisa umhlinzeki wakho wezempilo ngayo yonke imithi kanye nezithasiselo ozithathayo.

Izinzuzo ze-Ustekinumab

I-Ustekinumab inikeza izinzuzo eziningana zezokwelapha nezisebenzayo:

• Ukwelapha Okuhlosiwe: Ihlose ngqo izimbangela eziyisisekelo zezifo zokuzivikela komzimba, okuholela ekuphathweni kwezimpawu okuphumelelayo kakhudlwana.
• Imiphumela Ehlala Isikhathi Eside: Iziguli eziningi zithola impumuzo ende ezimpawini, okunciphisa ukuvama kokujova.
• Ikhwalithi Yempilo Ethuthukisiwe: Ngokuphatha izimpawu ngempumelelo, i-Ustekinumab ingathuthukisa kakhulu ikhwalithi yokuphila kweziguli ezinezimo ezingamahlalakhona.

Ukuphikisana kwe-Ustekinumab

Abantu abathile kufanele bagweme ukusebenzisa i-Ustekinumab, okuhlanganisa:

• Abesifazane Abakhulelwe noma Abancelisa Ibele: Imiphumela ekukhuleni kombungu ayiqondwa ngokugcwele, ngakho-ke ngokuvamile kuyalulekwa ukugwema lo muthi ngesikhathi sokukhulelwa nokuncelisa.
• Amagciwane Amakhulu: Iziguli ezinezifo ezisebenzayo akufanele zisebenzise i-Ustekinumab kuze kube yilapho ukutheleleka sekuqediwe.
• Ukuzwela okukhulu: Abantu abanolwazi lokuzwela i-ustekinumab noma izinto ezihambisana nayo akufanele bathathe lo muthi.

Ukuqapha Nezexwayiso

Ngaphambi kokuqala i-Ustekinumab, iziguli kufanele zenze izivivinyo ezithile zelebhu ukuze kuhlolwe impilo yazo iyonke, okuhlanganisa:

• Ukuhlolwa kwesifo sofuba (i-TB): Iziguli kufanele zihlolwe i-TB ecashile noma ezinye izifo ngaphambi kokuqala ukwelashwa, njengoba i-Ustekinumab ingandisa ingozi yokuvuselelwa.
• Ukuhlolwa kwegciwane le-Hepatitis B (HBV): Ukuhlolwa kwe-HBV ngenxa yengozi yokuvuselelwa.
• Ukuhlolwa Kokusebenza Kwesibindi: Kunconywa ukuqapha njalo ama-enzyme esibindi ukuze kutholakale noma yiziphi izinkinga zesibindi kusenesikhathi.

Iziguli kufanele futhi ziqaphele izimpawu zokutheleleka futhi zibike noma yiziphi izimpawu ezifana nomkhuhlane, ukubanda, noma ukukhwehlela okuqhubekayo kumhlinzeki wazo wezempilo.
