Ejenti antianginal

ejenti Antianginal - labo abangabakhe iqembu kwemithi enqunyiwe phakathi ekwelapheni angina. Lesi sifo libhekene ekuhlaseleni ubuhlungu endaweni inhliziyo, kanye kwesokunxele ingalo noma ehlombe blade. Igama izidakamizwa engabelwe angina, livela egameni lesi sifo e-Latin - pectoris Angina (angina pectoris).

Ukwahlukanisa izidakamizwa antianginal kuhlanganisa namaqembu ezine eziyinhloko:

1. nitrite nemikhiqizo kamanyolo Lokudabuka organic - imithi efana "nitroglycerin," "Nitrong", "Sustak", "amilnitrit".

2. ukwakhiwa ethwele ukuvinjelwa iziteshi calcium - "nifedipine" "Verapamil," "Diltiazem".

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

4. Amalungiselelo umthelela myotropic kokuba yenhliziyo dilator izakhiwo - "Cha-spa", "papaverine", "Dipyridamole".

Isizathu esikhulu angina ukunciphisa umoyampilo olunikezwe yi nemithambo yegazi yenhliziyo ne ukukhula kwesidingo ke infarction. inqubo enjalo kungenzeka ukwandisa nobukhali Kufinyeta of imisipha yenhliziyo ezimweni ezicindezelayo noma lapho uvivinya umzimba. ejenti Antianginal ukukhuthaza esivimba amanzi nomoya-mpilo saturation. Lesi senzo kungenziwa kwelinye izinkomba ezimbili:

1. Effect ku inqubo kwegazi ngokusebenzisa anda imithambo yegazi i-coronary, ngaleyo ndlela kwande umoyampilo ilethwa.

2. Ithonya Lako myocardium noma izitsha neuropathy, esehlisa inhliziyo futhi kunciphisa umoya-mpilo yayo funa.

izidakamizwa Antianginal ezithinta ukugeleza kwegazi, uphakathi kwabantu abangenalo leli kwemithi isinyathelo myotropic. Basuke Kunconywa angina kusaqalwa ngakho, kanye neziguli abasebasha, ngoba le mithi nethonya elitheni endleleni umsebenzi izitsha yenhliziyo. Umthelela enkulu yaleli qembu izidakamizwa akwazi nomuthi "Dipyridamole," kodwa hhayi elawulwa phakathi ischemia, okuyinto umphumela isifo sokuqina kwemithambo yegazi.

ejenti Antianginal iziphi kabanzi kunazo lisetshenziswe umkhuba yesimanje zokwelapha, kungawuthinta umzimba ngezindlela ezahlukene. Ziyakwazi initiators of inqubo ukwandiswa we ukuxhumelela imithambo yenhliziyo futhi ukunciphisa imisipha yenhliziyo. Le mithi ihlanganisa eqenjini nitrate organic, beta-blocker kanye potassium abantu abamelene nani.

Indlela eyinhloko ukuze imikhankaso yosizo oluphuthumayo ka-acute ekuhlaseleni angina useyayamukela izidakamizwa "nitroglycerin". Lesi sidakamizwa likhona iqembu nitrites nemikhiqizo kamanyolo organic. Unekhono ngokushesha ukungena egazini nesivinini sokuhlinzeka nomphumela oqabulayo. Nokho, umphumela wawo umzimba ubabonisa akukho imizuzu engaphezu kuka amathathu. Ukuze unikeze ngolunye eside imithelela Sustac izidakamizwa ' "nethi" Nitrong ", kuhlanganisa e isibalo samalungu alo nitroglycerin, ebiyelwe microcapsules. Lokhu kuvumela idatha izidakamizwa kancane kancane eyakhishwa ngo ipheshana wokugaya ukudla futhi abe ithonya elihle emzimbeni amahora amathathu kuya kwamane. Izidakamizwa baleli qembu yilabo ingcindezi kwesejwayelekile e emithanjeni yegazi futhi abangele imisipha yenhliziyo ukusebenza ezimweni umthwalo evumayo. Le nqubo kunciphisa nesidingo-mpilo ka myocardium.

ejenti Antianginal ekuvimbeni iziteshi calcium, kunciphisa inani le-ukusikwa esivimba amanzi kanye okukhipha inhliziyo. Imiphumela yawo emzimbeni ngenxa isenzo cardiodepressivny. Le mithi ukuvimba iziteshi calcium ngokufaka uhlelo nokuqhuba inhliziyo, esiza kususe spasm imisipha bushelelezi futhi ukwandisa umoya-mpilo umncane ukuze myocardium.

Antihistamine amaqembu Beta adrenoblokatornoy bayakwazi ukuvimbela isenzo adrenaline. Ngakho, le mithi ukunciphisa ukwanda wegazi, tachycardia futhi Kufinyeta inhliziyo cuphuluza izimo ukucindezeleka futhi imisipha umthwalo.
