I-Isosorbide_Dinitrate

Isingeniso: Kuyini i-Isosorbide Dinitrate?

I-Isosorbide Dinitrate umuthi osetshenziswa kakhulu ukwelapha i-angina pectoris, uhlobo lobuhlungu besifuba obubangelwa ukwehla kokugeleza kwegazi enhliziyweni. Ingowesigaba semithi eyaziwa ngokuthi ama-nitrate, esebenza ngokukhulula nokwandisa imithambo yegazi, okuvumela ukugeleza kwegazi okuthuthukisiwe. Lo muthi uvame ukunqunyelwa iziguli ezinezinkinga zenhliziyo ukusiza ukuphatha izimpawu nokuthuthukisa ikhwalithi yokuphila.

Ukusetshenziswa kwe-Isosorbide Dinitrate

I-Isosorbide Dinitrate ivunyelwe ukusetshenziswa kwezokwelapha okuningana, okuhlanganisa:

• I-Angina Pectoris: Isetshenziswa ngokuyinhloko ukuvimbela nokwelapha iziqephu ze-angina, okusiza ekunciphiseni ubuhlungu besifuba.
• Ukwehluleka kwenhliziyo: Ingasetshenziswa kanye neminye imithi yokwelapha izimpawu zokwehluleka kwenhliziyo.
• I-Hypertension: Kwezinye izimo, ingasetshenziswa ukwehlisa umfutho wegazi, ikakhulukazi ezindaweni eziphuthumayo.

Indlela Esebenza

I-Isosorbide Dinitrate isebenza ngokuguqula ibe yi-nitric oxide emzimbeni, ekhulula imisipha ebushelelezi emithanjeni yegazi. Lokhu kuphumula kuholela ekuvulekeni kwemithambo yegazi, noma ukwandiswa kwemithambo yegazi, okunciphisa umthwalo womsebenzi enhliziyweni futhi kuthuthukise ukugeleza kwegazi. Ngokunciphisa inani legazi elibuyela enhliziyweni (preload) kanye nokunciphisa ukumelana inhliziyo okufanele isebenze ngokumelene nakho (afterload), kusiza ekunciphiseni izimpawu ze-angina futhi kuthuthukise ukusebenza kwenhliziyo iyonke.

Isilinganiso nokuphathwa

Umthamo we-Isosorbide Dinitrate ungahluka ngokuya ngesimo eselashwayo kanye nempendulo yesiguli. Nazi iziqondiso ezijwayelekile:

• Abantu abadala: Umthamo ojwayelekile wokuqala we-angina u-5 mg uthathwa ngomlomo, kabili kuya kathathu ngosuku. Umthamo ungalungiswa ngokusekelwe ekusebenzeni kahle kanye nokubekezelela, okungenani u-40 mg ngosuku.
• Ukusetshenziswa Kwezingane: Ukuphepha nokusebenza kahle ezinganeni akukaqinisekiswa, ngakho-ke ngokuvamile akunconywa ezigulini zezingane ngaphandle kwesiqondiso sikadokotela.
• Amafomu: I-Isosorbide Dinitrate itholakala ngezindlela ezahlukene, okuhlanganisa amaphilisi omlomo, ama-capsule akhululwa isikhathi eside, kanye namaphilisi angaphansi kwezilimi.

Imiphumela Engemihle ye-Isosorbide Dinitrate

Imiphumela emibi evamile ingafaka:

• bekhanda

• Ukukhathala

Imiphumela emibi kakhulu, nakuba ingavamile, ingabandakanya:

• Umfutho wegazi ophansi kakhulu (i-hypotension)
• Ukuphelelwa amandla
• Ukungezwani komzimba (ukuqubuka, ukulunywa, ukuvuvukala)
• Ukwandisa izinga lenhliziyo

Iziguli kufanele zifune usizo lwezokwelapha uma zithola imiphumela emibi kakhulu noma izimpawu zokusabela kokungezwani komzimba.

Ukusebenzisana kwezidakamizwa

I-Isosorbide Dinitrate ingasebenzisana nemithi eminingana kanye nezinto, okuhlanganisa:

• Amanye ama-Nitrate: Ukusebenzisa namanye ama-nitrate kungandisa ingozi yokwehla komfutho wegazi.
• Izithibi ze-Phosphodiesterase-5: Imithi efana ne-sildenafil (i-Viagra) ingabangela ukwehla okuyingozi komfutho wegazi uma ithathwa nge-Isosorbide Dinitrate.
• Utshwala: Ukuphuza utshwala kungathuthukisa imiphumela yokwehlisa umfutho wegazi, okuholela ekwandeni kwesiyezi noma ukuquleka.

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

Izinzuzo ze-Isosorbide Dinitrate

Izinzuzo zezokwelapha ze-Isosorbide Dinitrate zifaka:

• Ukwelapha i-Angina Okuphumelelayo: Inikeza impumuzo esheshayo ezimpawini ze-angina futhi isiza ukuvimbela izigameko zesikhathi esizayo.
• Ukubekezelela Ukuzivocavoca Okuthuthukisiwe: Iziguli zivame ukuba nekhono elikhulayo lokwenza imisebenzi yomzimba ngaphandle kobuhlungu besifuba.
• Ukulawula Ukwehluleka Kwenhliziyo: Kungaba usizo ekuphatheni izimpawu zokwehluleka kwenhliziyo, kuthuthukise ukusebenza kwenhliziyo iyonke.

Ukuphikisana kwe-Isosorbide Dinitrate

Abantu abathile kufanele bagweme ukusebenzisa i-Isosorbide Dinitrate, okuhlanganisa:
