Macitentan - Uses, Dosage, Side Effects and More

Isingeniso: Kuyini iMacitentan?

I-Macitentan umuthi osetshenziswa kakhulu ukwelapha umfutho wegazi ophezulu we-pulmonary arterial hypertension (PAH), isimo esibonakala ngomfutho wegazi ophezulu emithanjeni yegazi ehlinzeka ngamaphaphu. Ngokubhekisisa izindlela eziyisisekelo zalesi sifo, i-Macitentan isiza ekuthuthukiseni amandla okuzivocavoca kanye nekhwalithi yokuphila kweziguli. Iyingxenye yeqembu lemithi eyaziwa ngokuthi ama-endothelin receptor antagonists, asebenza ngokuvimbela imiphumela ye-endothelin, into emzimbeni ebangela ukuba imithambo yegazi inciphe.

Ukusetshenziswa kwe-Macitentan

I-Macitentan ivunyelwe ukwelapha umfutho wegazi ophezulu we-pulmonary arterial (PAH) kubantu abadala. Ikhonjiswa ezigulini ezinezimpawu ze-WHO functional class II kuya ku-III, okusho ukuthi ifanele labo abahlangabezana nokulinganiselwa okuthile emsebenzini womzimba kodwa abasakwazi ukwenza imisebenzi yansuku zonke. Lo muthi uvame ukusetshenziswa kanye nezinye izindlela zokwelapha ukuthuthukisa ukusebenza kwawo nokuthuthukisa imiphumela yeziguli.

Indlela Esebenza

I-Macitentan isebenza ngokuvimbela isenzo se-endothelin1, i-vasoconstrictor enamandla enciphisa imithambo yegazi futhi inyuse umfutho wegazi. Ngokuvimbela lesi sidakamizwa, i-Macitentan isiza ukuphumula nokwandisa imithambo yegazi emaphashini, inciphise umfutho emithanjeni yamaphaphu. Le ndlela ayigcini nje ngokunciphisa izimpawu ezihlobene ne-PAH kodwa futhi ithuthukisa ukugeleza kwegazi kanye nokuhanjiswa komoya-mpilo emzimbeni wonke.

Isilinganiso nokuphathwa

Umthamo ojwayelekile wabantu abadala we-Macitentan uvame ukuba ngu-10 mg othathwa kanye ngosuku, ngokudla noma ngaphandle kokudla. Itholakala ngesimo sethebhulethi, okwenza kube lula ngeziguli ukuyifaka emisebenzini yazo yansuku zonke. Ezinganeni ezigulayo, umthamo ungahluka ngokuya ngezidingo zomuntu ngamunye futhi kufanele unqunywe ngumhlinzeki wezempilo. Kubalulekile ukulandela umthamo onqunyiwe futhi ungadluli inani elinconyiwe ukuze ugweme imiphumela emibi engaba khona.

Imiphumela Engemihle ye-Macitentan

Njengayo yonke imithi, iMacitentan ingabangela imiphumela emibi. Imiphumela emibi evamile ihlanganisa:

• bekhanda
• Ukungqubuzana kwe-nasal
• Flushing
• I-anemia
• Ukuvuvukala emilenzeni noma emaqakaleni

Imiphumela emibi kakhulu ingase ihlanganise:

• Izinkinga zesibindi (eziboniswa ukuphuzi kwesikhumba noma amehlo)
• Umfutho wegazi ophansi
• Ukusabela okukhulu kwe-allergic (ukuqubuka, ukulunywa, ukuvuvukala)
• I-pulmonary edema (uketshezi emaphashini)

Iziguli kufanele zibike noma yiziphi izimpawu ezingajwayelekile noma ezinzima kumhlinzeki wazo wezempilo ngokushesha.

Ukusebenzisana kwezidakamizwa

I-Macitentan ingasebenzisana nemithi eminingana, okungathinta ukusebenza kwayo noma kwandise ingozi yemiphumela emibi. Ukusebenzisana okukhulu kwemithi kufaka phakathi:

• Ezinye izitha ze-endothelin receptor
• Imithi ethile ye-antifungal (isb, i-ketoconazole)
• Imithi yokulwa negciwane lengculazi (isib. i-ritonavir)
• Imithi ethinta ama-enzyme esibindi (isib. i-rifampin)

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

Izinzuzo zeMacitentan

Izinzuzo zezokwelapha zokusebenzisa iMacitentan zifaka:

• Ukuthuthukiswa kwamandla okuzivocavoca kanye nekhwalithi yokuphila kweziguli ezine-PAH.
• Ukunciphisa ingozi yokuqhubeka kwesifo kanye nokulaliswa esibhedlela okuhlobene ne-PAH.
• Umthamo kanye ngosuku, okuthuthukisa ukunamathela ekwelashweni.
• Kungenzeka ukusetshenziswa kanye nezinye izindlela zokwelapha ukuze kube nendlela ebanzi yokuphatha i-PAH.

Izimo ze-Macitentan

Abantu abathile kufanele bagweme ukusebenzisa iMacitentan, okuhlanganisa:

• Abesifazane abakhulelwe, njengoba kungalimaza ingane esanda kuzalwa.
• Iziguli ezinesifo sesibindi esinzima, njengoba umuthi uguqulwa esibindini.
• Abantu abanokuzwela okukhulu ku-Macitentan noma kunoma yiziphi izingxenye zayo.

Umlando wezokwelapha ophelele kanye nokuhlolwa kubalulekile ngaphambi kokuqala ukwelashwa.

Ukuqapha Nezexwayiso

Ngaphambi kokusebenzisa i-Macitentan, iziguli kufanele zenze izivivinyo ezithile zelebhu ukuze kuhlolwe ukusebenza kwesibindi, njengoba umuthi ungathinta ama-enzyme esibindi. Kubalulekile futhi ukuqapha umfutho wegazi njalo, njengoba i-Macitentan ingabangela ukwehla komfutho wegazi. Iziguli kufanele ziqaphele lapho zenza imisebenzi edinga ukuqaphela, njengoba kungase kube nesiyezi.
