I-Palbociclib

Isingeniso: Kuyini iPalbociclib?

I-Palbociclib umuthi wokwelapha oqondiwe osetshenziswa kakhulu ekwelapheni izinhlobo ezithile zomdlavuza webele. Ingowesigaba semithi eyaziwa ngokuthi i-cyclindependent kinase (CDK) inhibitors. Ngokuphazamisa umjikelezo wamaseli omdlavuza, i-Palbociclib isiza ekunciphiseni noma ekumiseni ukukhula kwamaseli omdlavuza, okwenza kube inketho ebalulekile ezigulini ezine-hormone receptor-positive, human epidermal growth factor receptor 2negative (HR+/HER2) umdlavuza webele.

Ukusetshenziswa kwe-Palbociclib

I-Palbociclib ivunyelwe ukusetshenziswa kanye nama-aromatase inhibitors noma i-letrozole njengokwelashwa kokuqala kwabesifazane asebedlulile esikhathini sokuya esikhathini abanomdlavuza webele we-HR+/HER2. Iphinde ikhonjiswe ukuthi isetshenziswe kanye nomuthi we-antiestrogen i-fulvestrant ezigulini ezike zathola ukwelashwa kwe-endocrine ngaphambilini. Lo muthi uzuzisa kakhulu iziguli ezinomdlavuza webele othuthukile noma osakazeke kakhulu, lapho ukwelashwa kwendabuko kungase kungasebenzi kahle.

Indlela Esebenza

I-Palbociclib isebenza ngokuvimbela amaprotheni athile aziwa ngokuthi ama-cyclindependent kinases 4 kanye no-6 (CDK4/6). Lawa maprotheni adlala indima ebalulekile ekulawuleni umjikelezo weseli, okuyinqubo lapho amangqamuzana ekhula futhi ehlukana khona. Ngokuvimba i-CDK4/6, i-Palbociclib ivimbela amangqamuzana omdlavuza ukuthi aqhubekele phambili emjikelezweni weseli, inciphise ukukhula kwawo nokwanda kwawo ngempumelelo. Le ndlela ivumela ezinye izindlela zokwelapha, njengokwelashwa ngama-hormone, ukuthi zisebenze kahle kakhulu ngokumelene nomdlavuza.

Isilinganiso nokuphathwa

I-Palbociclib inikezwa ngomlomo ngesimo sethebhulethi. Umthamo ojwayelekile wabantu abadala uvame ukuba ngu-125 mg othathwa kanye ngosuku izinsuku ezingu-21 zilandelana, kulandelwe ikhefu lezinsuku ezingu-7 (umjikelezo wezinsuku ezingu-28). Lolu hlobo lomuthi lungahluka ngokuya ngezici zesiguli ngasinye, okuhlanganisa ukusebenza kwesibindi kanye nokubekezelela umuthi. Kubalulekile ukuthi iziguli zilandele imiyalelo yomhlinzeki wazo wezempilo mayelana nomthamo kanye nokuphathwa kwawo.

Imiphumela Engemihle yePalbociclib

Imiphumela emibi evamile ye-Palbociclib ihlanganisa:

• I-Neutropenia (inani eliphansi lamaseli amhlophe egazi)
• Ukukhathala
• I-nausea
• Uhudo
• Ukulahlekelwa izinwele
• Izilonda zomlomo

Imiphumela emibi kakhulu ingase ihlanganise:

• Ukutheleleka okukhulu okubangelwa ukubalwa kwamaseli amhlophe egazi aphansi
• Izinkinga zesibindi (ama-enzyme esibindi aphezulu)
• Ama-clots egazi
• I-Pneumonitis (ukuvuvukala kwamaphaphu)

Iziguli kufanele zibike noma yiziphi izimpawu noma imiphumela emibi engavamile kumhlinzeki wazo wezempilo ngokushesha.

Ukusebenzisana kwezidakamizwa

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

• Ama-inhibitors e-CYP3A4 anamandla (isib. i-ketoconazole, i-ritonavir) angakhuphula amazinga e-Palbociclib, okuholela ebuthi.
• Ama-inducer anamandla e-CYP3A4 (isib. i-rifampin, i-St. John's Wort) anganciphisa amazinga e-Palbociclib, anciphise ukusebenza kwayo.
• Eminye imithi ethinta ama-enzyme esibindi ingase ihlanganyele ne-Palbociclib.

Iziguli kufanele zazise umhlinzeki wazo wezempilo ngayo yonke imithi, izithasiselo, kanye nemikhiqizo yamakhambi abayithathayo.

Izinzuzo zePalbociclib

Izinzuzo zezokwelapha zokusebenzisa i-Palbociclib zifaka:

• Ukusinda okungenazo izinkinga zokuqhubekela phambili okuthuthukisiwe ezigulini ezine-HR+/HER2 cancer.
• Ukusebenza kahle okuthuthukisiwe uma kusetshenziswa kanye nokwelashwa ngama-hormone.
• Indlela eqondiwe enciphisa umonakalo kumaseli anempilo uma kuqhathaniswa ne-chemotherapy yendabuko.
• Ukulula kokuphathwa ngomlomo, okuvumela ukuhlanganiswa okulula empilweni yansuku zonke.

Izimo ze-Palbociclib

I-Palbociclib kufanele igwenywe kwezinye imiphakathi, okuhlanganisa:

• Abesifazane abakhulelwe noma abancelisayo, njengoba kungalimaza ingane noma usana.
• Iziguli ezinokukhubazeka okukhulu kwesibindi, njengoba umuthi uguqulwa esibindini.
• Abantu abanokuzwela okukhulu ku-Palbociclib noma kunoma yiziphi izingxenye zayo.

Ukuqapha Nezexwayiso

Ngaphambi kokuqala i-Palbociclib, iziguli kufanele zenze izivivinyo zelebhu ukuze kuhlolwe ukusebenza kwesibindi kanye nokubalwa kwamaseli egazi. Ukuqapha njalo kubalulekile ukuze kutholakale noma yimiphi imiphumela emibi engaba khona kusenesikhathi. Iziguli kufanele futhi ziqaphele ingozi yokutheleleka ngenxa yokubalwa kwamaseli amhlophe egazi aphansi futhi kufanele zithole usizo lwezokwelapha uma zithola umkhuhlane, ukubanda, noma ezinye izimpawu zokutheleleka.
