Dolasetron - Uses, Dosage, Side Effects and More

Isingeniso: Kuyini i-Dolasetron?

I-Dolasetron umuthi osetshenziswa kakhulu ukuvimbela isicanucanu nokuhlanza okubangelwa yi-chemotherapy noma ukuhlinzwa. Ingowesigaba semithi eyaziwa ngokuthi ama-receptor antagonists angu-5-HT3, asebenza ngokuvimbela isenzo se-serotonin, into yemvelo emzimbeni engabangela isicanucanu nokuhlanza. I-Dolasetron itholakala kokubili ngomlomo nangokwemijovo, okwenza ibe nokuguquguquka kwezidingo ezahlukahlukene zesiguli.

Ukusetshenziswa kwe-Dolasetron

I-Dolasetron ivunyelwe ukusetshenziswa kwezokwelapha eziningana, okuhlanganisa:

• Ukuvimbela isicanucanu nokuhlanza okuhambisana nokwelashwa ngamakhemikhali ezigulini ezinomdlavuza.
• Ukuvimbela isicanucanu nokuhlanza ngemva kokuhlinzwa.

Indlela Esebenza

I-Dolasetron isebenza ngokuvimba ama-serotonin receptors ebuchosheni nasendleleni yokugaya ukudla. Lapho kwenziwa i-chemotherapy noma ukuhlinzwa, amazinga e-serotonin angakhuphuka, okuholela emizweni yokucanuzela. Ngokuvimba la ma-receptor, i-Dolasetron inciphisa ngempumelelo izimpawu ezibangela isicanucanu nokuhlanza, okusiza iziguli zizizwe zikhululekile ngesikhathi sokwelashwa kwazo.

Isilinganiso nokuphathwa

Umthamo we-Dolasetron uyahlukahluka ngokuya ngobudala besiguli, isisindo, kanye nesimo esithile sezokwelapha. Nazi izilinganiso ezijwayelekile:

• Abantu abadala: Umthamo ojwayelekile wabantu abadala u-100 mg uthathwa ngomlomo ihora eli-1 kuya kwamabili ngaphambi kokwelashwa ngamakhemikhali noma u-12.5 mg uphathwa ngemithambo yegazi (IV) ngaphambi kokuhlinzwa.
• Izingane: Ezinganeni ezineminyaka engu-2 kuya kwengu-16 ubudala, umthamo onconywayo womlomo ngu-1.0 mg/kg (kufika ku-100 mg) othathwa ihora eli-1 kuya kwamabili ngaphambi kokwelashwa ngamakhemikhali.

I-Dolasetron inganikezwa njengephilisi noma ngomjovo, kuye ngesimo kanye nokukhetha kwesiguli.

Imiphumela Engemihle ye-Dolasetron

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

• bekhanda
• isiyezi
• Ukukhathala
• ukuqunjelwa

Imiphumela emibi kakhulu ingase ihlanganise:

• Ukushaya kwenhliziyo okungajwayelekile (arrhythmia)
• Ukusabela okukhulu kwe-allergic (ukuqubuka, ukulunywa, ukuvuvukala)

Iziguli kufanele zifune usizo lwezokwelapha uma ziba nemiphumela emibi kakhulu.

Ukusebenzisana kwezidakamizwa

I-Dolasetron ingasebenzisana nemithi eminingana, okungathinta indlela esebenza kahle ngayo noma kwandise ingozi yemiphumela emibi. Ukusebenzisana okukhulu kwemithi kuhlanganisa:

• Eminye imithi ethinta isigqi senhliziyo (isb., imithi yokulwa nokushaya kwenhliziyo)
• Imithi enweba isikhathi se-QT (kufaka phakathi imithi ethile yokulwa nokuphazamiseka kwengqondo kanye nemithi yokucindezeleka).

Ngaso sonke isikhathi wazisa umhlinzeki wakho wezempilo mayelana nayo yonke imithi oyiphuzayo ukuze ugweme ukusebenzisana okungenzeka.

Izinzuzo ze-Dolasetron

I-Dolasetron inikeza izinzuzo eziningana zezokwelapha nezisebenzayo:

• Kusebenza kahle ekuvimbeleni isicanucanu nokuhlanza ezigulini ezithola ukwelashwa ngamakhemikhali nokuhlinzwa.
• Itholakala kokubili ngomlomo kanye namafomu okujova, okunikeza ukuguquguquka kokusetshenziswa.
• Ngokuvamile kubekezelelwa kahle ngephrofayili yemiphumela emibi elawulekayo.

Izimo zokuphikisana ne-Dolasetron

Abantu abathile kufanele bagweme ukusebenzisa i-Dolasetron, okuhlanganisa:

• Iziguli ezinesifo sokungezwani komzimba esaziwayo neDolasetron noma ezinye zezingxenye zayo.
• Abantu abane-congenital long QT syndrome noma i-QT prolongation eyaziwa.
• Abesifazane abakhulelwe noma abancelisayo kufanele baxhumane nodokotela wabo ngaphambi kokusebenzisa.

Ukuqapha Nezexwayiso

Ngaphambi kokusebenzisa i-Dolasetron, iziguli kufanele zixoxe ngomlando wazo wezokwelapha nomhlinzeki wazo wezempilo, ikakhulukazi uma zinalokhu okulandelayo:

• Izinkinga zenhliziyo noma umlando womndeni we-arrhythmias.
• Isifo sesibindi, lapho kunconywa khona ukuthi kusetshenziswe ngokucophelela.
• Umlando wokusabela kokungezwani komzimba nemithi efanayo.

Kungadingeka ukuqapha njalo iziguli ezinezimo zempilo ezikhona.

• I-Anzemet

Isiphetho

I-Dolasetron iyimithi ewusizo yokuvimbela isicanucanu nokuhlanza ezigulini ezithola ukwelashwa ngamakhemikhali, noma ukuhlinzwa. Njengoba isebenza kahle futhi ivumela izindlela zokuphatha eziguquguqukayo, idlala indima ebalulekile ekuthuthukiseni induduzo yesiguli ngesikhathi sokwelashwa. Kodwa-ke, kubalulekile ukusebenzisa i-Dolasetron ngaphansi kwesiqondiso somhlinzeki wezempilo ukuqinisekisa ukuphepha nokusebenza kahle.
