Arhente antianginal

arhente Antianginal - abo kwiqela namayeza amiselwe ngexesha unyango angina. Esi sifo luphawulwa ukuhlaselwa intlungu ndawo entliziyweni, ngokunjalo kwi ekhohlo ingalo okanye maliwe. Igama imithi angina, lisuka kwigama le sifo Latin - sifuba angina (angina sifuba).

Ucalulo amachiza antianginal kuquka amaqela ezine eziphambili:

1. nayitrayithi kunye nitrate organic imvelaphi - amayeza afana "nitroglycerin," "Nitrong", "Sustak", "amilnitrit".

2. nemixube ethwele kuvalwe iindlela amajelo calcium - "nifedipine" "Verapamil," "Diltiazem".

3. Beta-blocker - lithetha "Popranolol" "Atenolol", "metoprolol".

4. Amalungiselelo impembelelo myotropic ukuba iipropati dilator coronary - "No-Spa", "papaverine", "Dipyridamole".

Oyena nobangela angina kukunciphisa isixa oxygen ezinikwa nemithambo yenhliziyo kunye ukwanda kwemfuno kuyo iposi. Loo nkqubo kuyokwenzeka ukwandisa rhoqo nobukhali izishunqulelo kwemisipha intliziyo kwiimeko ezibangela okanye ngexesha umthambo. arhente Antianginal Ukukhuthaza engabalulekanga oxygen kufumaneka bantu. Esi senzo kunokwenziwa kwenye kumacala amabini:

1. Igalelo kwinkqubo ukujikeleza ngokusebenzisa imithambo yegazi nemithambo banda, ngaleyo ndlela kwande inani oksijini kusinda.

2. Isiphumo kwi myocardium okanye nempahla peripheral, leyo kunciphisa intliziyo yaye kunciphisa imfuno yayo oksijini.

amachiza Antianginal ezichaphazela flow igazi, kuba iqela amayeza amanyathelo myotropic. Bona ekucetyiswa ukuba angina xa nisaqala ngayo, kwakunye izigulane abancinane, kuba la machiza kuba nesiphumo esincinci umsebenzi iimpahla coronary. Enempembelelo enkulu yeli qela iziyobisi esikwaziyo ukuvelisa medicament "Dipyridamole," kodwa leyo ilawulwa ngexesha ischemia, nto leyo ke ngenxa yegazi.

arhente Antianginal ezisetyenziswa ngokubanzi malunga nokwenziwayo enyangayo mihla, zingachaphazela umzimba ngokusebenzisa iindlela ezahlukeneyo. Bona lwabasunguli inkqubo ukwandiswa kwemithambo yenhliziyo nokunciphisa imisipha intliziyo. La machiza aquka kwiqela nitrate organic, beta-blocker kunye abamelene potassium.

Indlela engundoqo uncedo olungxamisekileyo ahlekise ukuhlaselwa angina ufumana "Nitroglycerin" iziyobisi. Eli chiza iqukiwe iqela nitrites kunye nitrate organic. Unawo amandla ndzulu ngokukhawuleza egazini kunye nesantya kliniki isiphumo therapeutic. Noko ke, umonakalo waso umzimba oluya ngaphezu kwemizuzu eyi-amathathu. Ukuze kubonelelwe nemiphumela ixesha elide Sustac amachiza ' "yaye" Nitrong ", uquka kwi nitroglycerin kwamalungu ayo, abhijelwe microcapsules. Oku kukuvumela ichiza data ebegqwese yakhululwa wokugaya nokuba nempembelelo entle emzimbeni iiyure ezintathu ukuya kwisine. Iziyobisi kweli qela kukho uxinzelelo nganye ezinga malungu abantu ngemithambo kunye emithanjeni ukuba izihlunu intliziyo ukusebenza phantsi kweemeko kakuhle umthwalo. Le nkqubo kunciphisa imfuno oksijini myocardium.

arhente Antianginal uvimba amajelo calcium, ukucutha ubuninzi ucutheko engabalulekanga nemveliso intliziyo. iziphumo zabo umzimba ngenxa yesenzo cardiodepressivny. La machiza bavala amajelo calcium abangena kwisistim kokuqhutywa intliziyo, enceda bawubuyise spasm of izihlunu anencasa lonyuse unikezelo oxygen myocardium.

Antihistamines amaqela Beta adrenoblokatornoy bayakwazi ukuthintela inyathelo adrenaline. Ngenxa yoko, la machiza ukunciphisa ukwanda koxinzelelo lwegazi, tachycardia kunye izishunqulelo kwentliziyo nomsindo kwiimeko uxinezeleko kunye nomthwalo kwezihlunu.
