Ukuqonda ukusetyenziswa kwe-5-Isosorbide Mononitrate

I-5-Isosorbide mononitrate (ISMN) yonyango esekelwe kakuhle esetyenziselwa unyango lweemeko ezahlukeneyo ze-cardiovascular. Le khompawundi yinxalenye yodidi lwe-nitrate yeziyobisi, ezaziwa ngokukwazi kwabo ukuphucula ukuhamba kwegazi kunye nokunciphisa iimpawu zesifo senhliziyo. Ukuba unikwe eli yeza okanye ucinga ngeenzuzo ezinokubakho, ukuqonda ukusetyenziswa kwalo kunye nendlela elisebenza ngayo kubalulekile. Kweli nqaku, siza kuphonononga ephambiliI-5-isosorbide mononitrate isebenzisakunye nendlela enceda ngayo ukulawula iimeko zentliziyo ngokufanelekileyo.

Yintoni i-5-Isosorbide Mononitrate?

I-5-Isosorbide mononitrateiyeza le-nitrate elisebenza ngokuyintloko njenge-vasodilator, oku kuthetha ukuba inceda ukwandisa imithambo yegazi. Oku kubangela ukuhamba kwegazi okuphuculweyo kunye nokunciphisa uxinzelelo lwentliziyo. Ngokuqhelekileyo kumiselwe izigulane ezine-angina (intlungu yesifuba) okanye ukungaphumeleli kwentliziyo, kunye nalabo abaye batyandwa yintliziyo. I-5-Isosorbide mononitrate ifumaneka kuzo zombini ukukhutshwa ngokukhawuleza kunye nokukhutshwa okwandisiweyo ukukhutshwa, ukunika ukuguquguquka ekulawuleni iintlobo ezahlukeneyo zeemeko zentliziyo.

Ukusetyenziswa okuPhambili kwe-5-Isosorbide Mononitrate

1. Ukunyanga i-Angina

Enye yezona ziqhelekileyoI-5-isosorbide mononitrate isebenzisakulawulo lwe-angina. I-Angina yintlungu yesifuba okanye ukungonwabi okubangelwa kukuncipha kokuhamba kwegazi ukuya kwisihlunu sentliziyo, ngokufuthi ngenxa yesifo se-coronary artery. Ngokuphumla imithambo yegazi kunye nokuphucula ukujikeleza, i-5-isosorbide mononitrate inceda ukwandisa inani legazi eline-oksijini elifikelela entliziyweni, elinokunciphisa kakhulu ukuphindaphinda kunye nobunzima bokuhlaselwa kwe-angina.

Eli liyeza lihlala limiselwe njengenxalenye yesicwangciso sonyango olubanzi, olunokuthi lubandakanye namanye amayeza, utshintsho lwendlela yokuphila, kwaye ngamanye amaxesha ungenelelo lotyando.

2. Ukulawula ukungaphumeleli kweNtliziyo

Olunye usetyenziso olubalulekileyo lwe-5-isosorbide mononitrate kulawulo lokungaphumeleli kwentliziyo. Kwimeko yokusilela kwentliziyo, intliziyo iya ingasebenzi kakuhle ekumpompeni igazi, nto leyo ekhokelela ekwakhiweni kolwelo kunye nokuncipha kokuhanjiswa kweoksijini kumalungu abalulekileyo. Impembelelo ye-vasodilatory ye-5-isosorbide mononitrate inceda ukunciphisa umthwalo womsebenzi entliziyweni ngokunciphisa uxinzelelo kwimithambo yegazi, okwenza kube lula ukuba intliziyo impompe igazi.

Ngokuphucula ukuhamba kwegazi kunye nokunciphisa uxinzelelo entliziyweni, i-5-isosorbide mononitrate inceda ukukhusela ukuqhubela phambili kwentliziyo kunye nokuphucula umgangatho wobomi besigulane. Oku kuluncedo ngakumbi kubantu abanesifo sentliziyo esingapheliyo abafuna ulawulo lwexesha elide ukuthintela ukwanda.

3. Ukuthintela kunye nokuNyanga i-Ischemia

I-Ischemia yenzeka xa unikezelo lwegazi entliziyweni okanye kwamanye amalungu omzimba lungonelanga ukuhlangabezana neemfuno zezicubu. Le meko inokukhokelela kumonakalo kwimisipha yentliziyo kwaye yandise umngcipheko wokuhlaselwa yintliziyo. I-5-Isosorbide mononitrate ngamanye amaxesha isetyenziselwa izigulane ezine-ischemic heart disease ukukhusela ukuvela kwe-ischemia kunye nokunciphisa umngcipheko wokulimala kwentliziyo.

Ngokwandisa imithwalo yegazi kunye nokuphucula ukujikeleza, i-5-isosorbide mononitrate iqinisekisa ukuba i-oksijini eyaneleyo ifikelela kwi-heart muscle, nangona ukuhamba kwegazi kuphazamisekile. Oku kunceda ukukhusela intliziyo kumonakalo ngenxa ye-ischemia, okwenza kube liyeza elixabisekileyo kwizigulane ezisengozini.

4. UBuyiselo emva koCando

Izigulane eziye zafumana utyando lwentliziyo, njenge-coronary artery bypass grafting (CABG), zingaphinda zizuze kwi-5-isosorbide mononitrate. Ukulandela utyando, intliziyo ingaba phantsi koxinzelelo olongezelelweyo njengoko iphilisa, kwaye izigulane zinokufumana intlungu yesifuba okanye ukungahambi kakuhle ngexesha lokubuyisela. I-vasodilation ebonelelwa yi-5-isosorbide mononitrate inokunciphisa umthwalo entliziyweni ngeli xesha elinzima, ukuvumela ukubuyiswa okungcono kunye nokunciphisa umngcipheko weengxaki.

Isebenza njani i-5-Isosorbide Mononitrate?

I-5-Isosorbide mononitrate isebenza ngokuphumla izihlunu ezigudileyo zemithambo yegazi. Oku kubangela i-vasodilation, ekwandiswa kwemithambo yegazi. Eyona nzuzo iphambili yale mpembelelo kukuba yehlisa umyinge womsebenzi ekufuneka wenziwe yintliziyo ukumpompa igazi, ukunciphisa zombini ukusetyenziswa kweoksijini yentliziyo kunye noxinzelelo lwegazi ngaphakathi kwemithambo.

Ngokuphumla kunye nokwandisa imithwalo yegazi, i-5-isosorbide mononitrate iphucula ukuhamba kwegazi, eyona nto inenzuzo kubantu abaneemeko zentliziyo apho ukujikeleza kuphazamiseka. Liyeza elinyanyezelwe kakuhle elichazwa njengenxalenye yesicwangciso sonyango esibanzi sokulawula isifo sentliziyo.

Iimpembelelo ezinokubakho kunye neeNgqwalaselo

Nangona i-5-isosorbide mononitrate ixhatshazwa kakuhle, kubalulekile ukuba uqaphele imiphumo enokubakho. Oku kunokubandakanya intloko ebuhlungu, isiyezi, uxinzelelo lwegazi oluphantsi, kunye nesicaphucaphu. Kwezinye iimeko, ukunyamezela kunokukhula, oku kuthetha ukuba ukusebenza kweyeza kunokuncipha ngokuhamba kwexesha. Kubalulekile ukulandela imiyalelo yomboneleli wakho wezempilo malunga nedosi kunye namaxesha amaninzi ukuthintela naziphi na iingxaki.

Njengalo naliphi na iyeza, kubalulekile ukuxoxa ngembali yakho yonyango kunye nogqirha wakho, ngakumbi ukuba uneemeko ezifana ne-hypotension okanye imbali yokuhlaselwa yintliziyo. Umboneleli wakho wezempilo unokukunceda ukuba ubone ukuba i-5-isosorbide mononitrate yinto efanelekileyo yokukhetha imeko yakho ethile.

Isiphelo: Ukulawula iimeko zeNtliziyo ngokufanelekileyo
