Nilotinib - Uses, Dosage, Side Effects and More

I-Nilotinib umuthi wokwelapha oqondiwe osetshenziswa kakhulu ekwelapheni izinhlobo ezithile zomdlavuza wegazi, ikakhulukazi i-chronic myeloid leukemia (CML). Iyingxenye yeqembu lemithi eyaziwa ngokuthi i-tyrosine kinase inhibitors (TKIs), esebenza ngokuvimbela izimpawu ezithile kumaseli omdlavuza ezikhuthaza ukukhula nokuhlukana kwawo. Ngokuvimbela lezi zimpawu, i-nilotinib isiza ukulawula ukwanda kwamaseli omdlavuza, okuholela emiphumeleni ethuthukisiwe yeziguli ezine-CML.

Ukusetshenziswa kwe-Nilotinib

I-Nilotinib ivunyelwe kakhulu ekwelapheni i-chronic myeloid leukemia (CML) kubantu abadala nasezinganeni. Isebenza kahle kakhulu ezigulini ezine-chromosome yasePhiladelphia, okuwukungavamile kofuzo okuhlotshaniswa ne-CML. I-Nilotinib ivame ukusetshenziswa ezigulini ezisanda kutholakala zine-CML noma lezo ezingasabelanga ngokwanele kwezinye izindlela zokwelapha, njenge-imatinib. Ingasetshenziswa nasezimweni ze-CML eziye zathuthuka zaya esigabeni esithuthukile.

Indlela Esebenza

I-Nilotinib isebenza ngokuqondisa ngqo nokuvimbela umsebenzi weprotheyini ye-BCR-ABL, ekhiqizwa yi-chromosome yasePhiladelphia. Le protheyini inesibopho sokukhula okungalawuleki kwamaseli omdlavuza ku-CML. Ngokuvimba izimpawu ezithunyelwa yile protheyini, i-nilotinib ivimbela ngempumelelo amaseli omdlavuza ukuthi angaphindaphindeki futhi ingaholela ekunciphiseni inani lamaseli omdlavuza emzimbeni. Ngamagama alula, ungacabanga nge-nilotinib njengesihluthulelo esingena kukhiye (iprotheyini ye-BCR-ABL) futhi siyivimbele ekuvuleni umnyango wokukhula kwamaseli omdlavuza.

Isilinganiso nokuphathwa

Umthamo ojwayelekile we-nilotinib kubantu abadala uvame ukuba ngu-300 mg othathwa ngomlomo kabili ngosuku. Ezinganeni, umthamo ungahluka ngokuya ngesisindo somzimba kanye nohlelo oluthile lokwelashwa oluchazwe ngumhlinzeki wezempilo. I-Nilotinib itholakala ngesimo se-capsule futhi kufanele ithathwe esiswini esingenalutho, okungenani amahora ama-2 ngemva kokudla kanye nehora eli-1 ngaphambi kokudla okulandelayo. Kubalulekile ukulandela umthamo onqunyiwe kanye nokuhlela eduze ukuze wandise ukusebenza kahle komuthi.

Imiphumela Engemihle ye-Nilotinib

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

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

Imiphumela emibi kakhulu ingase ihlanganise:

• Izinkinga zenhliziyo (njenge-arrhythmias)
• Izinkinga zesibindi (ama-enzyme esibindi aphakeme)
• Ukubalwa kwamangqamuzana egazi aphansi (i-anemia, i-neutropenia, i-thrombocytopenia)
• Pancreatitis
• Ukungezwani komzimba okukhulu

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

Ukusebenzisana kwezidakamizwa

I-Nilotinib ingasebenzisana nemithi eminingana kanye nezinto, okungathinta ukusebenza kwayo noma kwandise ingozi yemiphumela emibi. Ukusebenzisana okukhulu kwemithi kuhlanganisa:

• Ama-antacid kanye nama-proton pump inhibitors (anganciphisa ukumuncwa kwe-nilotinib)
• Amanye ama-antibiotic (njenge-rifampin)
• Imithi yokulwa nesikhunta (njenge-ketoconazole)
• Ezinye izindlela zokwelapha umdlavuza (njengezinye i-TKI)

Kubalulekile ukuthi iziguli zazise umhlinzeki wazo wezempilo ngayo yonke imithi, izithasiselo, kanye nemikhiqizo yamakhambi eziyisebenzisayo ukuze zigweme ukusebenzisana okungenzeka.

Izinzuzo ze-Nilotinib

Ukusetshenziswa kwe-nilotinib kunikeza izinzuzo eziningana zezokwelapha, okuhlanganisa:

• Ukwelashwa okuhlosiwe: I-Nilotinib ihlasela ngqo amangqamuzana omdlavuza, inciphisa umonakalo kumaseli anempilo.
• Amanani okuphendula athuthukisiwe: Iziguli eziningi zithola ukwehla okukhulu kwamazinga amangqamuzana omdlavuza, okuholela emiphumeleni engcono iyonke.
• Ukuzijabulisa: I-Nilotinib ithathwa ngomlomo, okuvumela ukuthi kube lula ukuyiphatha uma kuqhathaniswa nokwelashwa ngemithambo yegazi.
• Kungenzeka ukuthi kukhululwe isikhathi eside: Ngokwelashwa okuphumelelayo, ezinye iziguli zingase zithole ukuphulukiswa kwesikhathi eside ngenxa ye-CML.

Ukuphikisana kwe-Nilotinib

Abantu abathile kufanele bagweme ukusebenzisa i-nilotinib, okuhlanganisa:

• Abesifazane abakhulelwe noma abancelisayo, njengoba kungalimaza ingane noma usana.
• Iziguli ezinesifo esibi sesibindi, njengoba i-nilotinib iguqulwa ibe yi-metabolite esibindini.
• Abantu abanokuzwela okukhulu kwe-nilotinib noma kunoma yiziphi izingxenye zayo.

Umhlinzeki wezempilo uzohlola izingozi nezinzuzo ngaphambi kokunikeza i-nilotinib.

Ukuqapha Nezexwayiso

Ngaphambi kokuqala i-nilotinib, iziguli kufanele zenze izivivinyo ezithile zelebhu ukuze kuqashwe ukusebenza kwesibindi kanye nokubalwa kwamaseli egazi. Ukuqokwa njalo kokulandela kubalulekile ukuqinisekisa ukuthi umuthi usebenza kahle futhi ulawule noma yimiphi imiphumela emibi. Iziguli kufanele futhi ziqaphele ukuthi kungenzeka yini izinkinga ezihlobene nenhliziyo futhi zibike noma yiziphi izimpawu ezifana nobuhlungu besifuba noma ukushaya kwenhliziyo kudokotela wazo.

• I-Tasigna

Isiphetho

I-Nilotinib iwumuthi obalulekile ekuphathweni kwe-leukemia engapheli ye-myeloid, enikeza ukwelashwa okuqondiwe okungaholela ekuthuthukisweni okukhulu emiphumeleni yeziguli. Njengoba iyindlela yayo yokusebenza ethile, iziqondiso zomthamo, kanye nemiphumela emibi engaba khona, kubalulekile ukuthi iziguli zisebenzisane eduze nabahlinzeki bazo bezempilo ukuqinisekisa ukwelashwa okuphephile nokuphumelelayo. Ukuqonda indima ye-nilotinib ekwelashweni kwe-CML kunganika iziguli amandla okwenza izinqumo ezinolwazi mayelana nempilo yazo.
