I-5-Isosorbide mononitrate (ISMN) imithi esungulwe kahle esetshenziselwa ukwelapha izimo ezihlukahlukene zenhliziyo. Le nhlanganisela iyingxenye yeqembu le-nitrate lezidakamizwa, ezaziwa ngamandla azo okuthuthukisa ukugeleza kwegazi nokunciphisa izimpawu zesifo senhliziyo. Uma unikezwe lo muthi noma ucabangela izinzuzo zawo ezingase zibe khona, ukuqonda ukusetshenziswa kwawo nendlela osebenza ngayo kubalulekile. Kulesi sihloko, sizohlola okuyinhlokoI-5-isosorbide mononitrate isebenzisanokuthi isiza kanjani ukuphatha izimo zenhliziyo ngempumelelo.
Iyini i-5-Isosorbide Mononitrate?
5-Isosorbide mononitrateumuthi we-nitrate osebenza ngokuyinhloko njenge-vasodilator, okusho ukuthi usiza ukukhulisa imithambo yegazi. Lokhu kubangela ukugeleza kwegazi okuthuthukisiwe nokuncipha kokucindezeleka enhliziyweni. Ngokuvamile kunqunyelwe iziguli ezine-angina (ubuhlungu besifuba) noma ukuhluleka kwenhliziyo, kanye nalabo abaye bahlinzwa inhliziyo. I-5-Isosorbide mononitrate itholakala kukho kokubili ukukhishwa okusheshayo nokukhishwa okunwetshiwe, okunikeza ukuguquguquka ekulawuleni izinhlobo ezahlukene zezimo zenhliziyo.
Ukusetshenziswa Okubalulekile kwe-5-Isosorbide Mononitrate
1. Ukwelapha i-angina
Enye evame kakhuluI-5-isosorbide mononitrate isebenzisaisekuphathweni kwe-angina. I-Angina ubuhlungu besifuba noma ukungakhululeki okubangelwa ukugeleza kwegazi okuncishisiwe kuya emisipha yenhliziyo, ngokuvamile ngenxa yesifo se-coronary artery. Ngokuphumuza imithambo yegazi nokuthuthukisa ukujikeleza kwegazi, i-5-isosorbide mononitrate isiza ukwandisa inani legazi elinomoya-mpilo elifinyelela enhliziyweni, elinganciphisa kakhulu imvamisa nokuqina kokuhlaselwa kwe-angina.
Lo muthi uvame ukubekwa njengengxenye yohlelo lokwelapha oluphelele, olungase luhlanganise neminye imithi, izinguquko zendlela yokuphila, futhi ngezinye izikhathi ukungenelela kokuhlinzwa.
2. Ukulawula Ukwehluleka Kwenhliziyo
Okunye ukusetshenziswa okuphawulekayo kwe-5-isosorbide mononitrate kukulawula ukuhluleka kwenhliziyo. Ekuhlulekeni kwenhliziyo, inhliziyo iyancipha ukusebenza kahle ekumpompeni igazi, okuholela ekwakhekeni koketshezi kanye nokuncipha kokulethwa komoyampilo ezithweni ezibalulekile. Umphumela we-vasodilatory we-5-isosorbide mononitrate usiza ukunciphisa umthwalo womsebenzi enhliziyweni ngokunciphisa ukucindezela emithanjeni yegazi, okwenza kube lula ngenhliziyo ukupompa igazi.
Ngokuthuthukisa ukugeleza kwegazi nokunciphisa ukucindezela enhliziyweni, i-5-isosorbide mononitrate isiza ukuvimbela ukuqhubeka kokwehluleka kwenhliziyo futhi ithuthukise izinga lokuphila lesiguli. Lokhu kuyasiza ikakhulukazi kubantu abanesifo senhliziyo esingapheli abadinga ukuphathwa isikhathi eside ukuze bavimbele ukwanda.
3. Ukuvimbela Nokwelapha Ischemia
I-Ischemia yenzeka lapho ukunikezwa kwegazi enhliziyweni noma kwezinye izingxenye zomzimba kunganele ukuhlangabezana nezidingo zezicubu. Lesi simo singaholela ekulimaleni kwemisipha yenhliziyo futhi sandise ingozi yokuhlaselwa yinhliziyo. I-5-Isosorbide mononitrate ngezinye izikhathi isetshenziselwa iziguli ezine-ischemic heart disease ukuvimbela ukuvela kwe-ischemia nokunciphisa ingozi yokulimala kwenhliziyo eyengeziwe.
Ngokwandisa imithambo yegazi nokuthuthukisa ukujikeleza kwegazi, i-5-isosorbide mononitrate iqinisekisa ukuthi i-oksijeni eyanele ifinyelela emisipha yenhliziyo, ngisho nalapho ukugeleza kwegazi kuphazamiseka. Lokhu kusiza ukuvikela inhliziyo emonakalweni ngenxa ye-ischemia, okwenza kube umuthi obalulekile ezigulini ezisengozini.
4. Ukubuyisela Ngemva Kokuhlinzwa
Iziguli eziye zahlinzwa inhliziyo, njenge-coronary artery bypass grafting (CABG), zingase futhi zizuze ku-5-isosorbide mononitrate. Ngemva kokuhlinzwa, inhliziyo ingase ibe ngaphansi kokucindezeleka okwengeziwe njengoba iphulukisa, futhi iziguli zingase zizwe ubuhlungu besifuba noma ukungakhululeki ngesikhathi sokululama. I-vasodilation ehlinzekwa yi-5-isosorbide mononitrate ingadambisa umthwalo enhliziyweni phakathi nalesi sikhathi esibucayi, okuvumela ukutakula okungcono nokunciphisa ingozi yezinkinga.
Isebenza kanjani i-5-Isosorbide Mononitrate?
I-5-Isosorbide mononitrate isebenza ngokuphumula imisipha ebushelelezi yemithambo yegazi. Lokhu kubangela i-vasodilation, okuwukunwebeka kwemithambo yegazi. Inzuzo eyinhloko yalo mphumela ukuthi wehlisa inani lomsebenzi inhliziyo okufanele yenze ukupompa igazi, kunciphisa kokubili ukusetshenziswa komoyampilo wenhliziyo nomfutho wegazi ongaphakathi kwemithambo.
Ngokuphumuza nokwandisa imithambo yegazi, i-5-isosorbide mononitrate ithuthukisa ukugeleza kwegazi, okuzuzisa kakhulu abantu abanezimo zenhliziyo lapho ukujikeleza kuphazamiseka. Kuwumuthi obekezelelwe kahle ovame ukubekwa njengengxenye yohlelo olubanzi lokwelapha lokulawula isifo senhliziyo.
Imithelela Engenzeka Engase Eceleni Nokucatshangelwa
Nakuba i-5-isosorbide mononitrate ngokuvamile ibekezelelwa kahle, kubalulekile ukuqaphela imiphumela emibi engaba khona. Lokhu kungase kuhlanganise ubuhlungu bekhanda, isiyezi, umfutho wegazi ophansi, nesicanucanu. Kwezinye izimo, ukubekezelelana kungakhula, okusho ukuthi ukusebenza kahle komuthi kungase kwehle ngokuhamba kwesikhathi. Kubalulekile ukulandela imiyalelo yomhlinzeki wakho wokunakekelwa kwezempilo mayelana nomthamo kanye nemvamisa ukuze ugweme noma yiziphi izinkinga.
Njenganoma yimuphi umuthi, kubalulekile ukuxoxa ngomlando wakho wezokwelapha nodokotela wakho, ikakhulukazi uma unezimo ezifana ne-hypotension noma umlando wokuhlaselwa yinhliziyo. Umhlinzeki wakho wokunakekelwa kwezempilo angasiza ekunqumeni ukuthi i-5-isosorbide mononitrate iyisinqumo esifanele yini esimweni sakho esithile.
Isiphetho: Ukuphatha Izimo Zenhliziyo Ngokuphumelelayo
II-5-isosorbide mononitrate isebenzisaokuvezwe lapha kubonisa ukuthi lo muthi udlala kanjani indima ebalulekile ekulawuleni izimo zenhliziyo, kusukela ekunciphiseni i-angina nokuvimbela i-ischemia ekusekeleni ukwelashwa kokuhluleka kwenhliziyo nokusiza ukululama ngemva kokuhlinzwa. Ngokuthuthukisa ukugeleza kwegazi nokunciphisa umthwalo wokusebenza enhliziyweni, i-5-isosorbide mononitrate isiza ukuthuthukisa ikhwalithi yokuphila yabantu abaningi abanesifo senhliziyo.
Uma wena noma othile omaziyo ebhekene nezimo zenhliziyo, kubalulekile ukuthintana nomhlinzeki wezempilo ukuze unqume ukuthi i-5-isosorbide mononitrate ingaba yini ingxenye yohlelo lokwelapha olusebenzayo. NgoI-Venture Entsha, sizibophezele ekuhlinzekeni izixazululo zokunakekelwa kwezempilo ezisezingeni eliphezulu ezimbonini ezihlukahlukene. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana neminikelo yethu nokuthi singasekela kanjani izidingo zakho zokunakekelwa kwezempilo.
