Kwiintlobo ezininzi, kuquka intliziyo, kunye nemithambo, izintso, i-airways nezinye izicubu, kukho i-beta-adrenergic receptors. Banoxanduva lobunzima, kwaye ngezinye iingozi, ukuphendulwa komzimba ukugqithisa nokuxinzelela ("hit okanye ugijime"). Ukunciphisa umsebenzi wabo kwiyeza, i-beta-blockers isetyenzisiweyo - uludwe lwezilwanyana ezivela kweli qela le-pharmacological likhulu kakhulu, elivumela ukukhetha iyeza elifanelekileyo kakhulu kwisigulane ngasinye.
I-beta-blockers abangakhethiyo
Kukho iintlobo ezimbini ze-adrenoreceptors-beta-1 kunye ne-beta-2. Xa ukuhlula kokuqala kuvaliwe, iziphumo ezilandelayo zentliziyo ziyafezwa:
- ukunciphisa izinga lentliziyo kunye nexesha;
- ukunciphisa uxinzelelo lwegazi;
- ukucinezelwa kwengqondo yomzimba.
Ukuba uvimba i-beta-2-adrenoreceptors, kukho ukwanda kwindlela yokumelana nomzila wegazi kunye neetoni:
- isisu (kwabasetyhini abakhulelweyo);
- bronchi;
- arterioles.
Ukulungiswa kwinqutyana ye-beta-blockers ye-nonselective ayisenzi ngokukhethayo, ukunciphisa umsebenzi wezo zombini iintlobo zamkeli.
Amachiza alandelayo abhekisela kumayeza achaziweyo:
- Oxprenolol;
- Propranolol;
- Pindolol;

I-beta-blockers ekhethiweyo
Ukuba isilwanyana sisebenza ngokukhetha kwaye sinciphisa ukusebenza kwe-beta-1-adrenergic receptors kuphela, yinto ekhethiweyo. Kubalulekile ukuba uqaphele ukuba ezo ziyobisi zikhethwayo kakhulu kwi -rapy ye-cardiovascular pathologies, ngaphandle koko, zivelisa iziphumo ezincinci.
Uluhlu lwezilwanyana ezivela kwiqela le-cardioselective beta-blockers yesizukulwana esitsha:
- Betacard;
- Atenolol;
- Tenolol;
- Prinorm;
- Bisoprolol;

- ICordanum;
- Acebutolol.
Imiphumo emibi ye-beta-blockers
Iziganeko ezibi zidla ngokubangela iziyobisi ezingakhethi. Ezi ziquka ezi zilandelayo:
- bradycardia ;
- imiqondiso yentliziyo yokuhluleka;
- i-hypotension;
- intlungu esifuba;
- ukuphazamiseka kokulala okanye ukulala;
- ukungcola;
- ukukhubazeka kwememori kunye nokukwazi ukugxininisa;
- ukudandatheka;
- iimbononongo ezibonwayo kunye nokuhlola;
- amandla aphantsi okusebenza;
- ukungakhathaleli;
- intloko;
- isicefe
- umlomo owomileyo;
- udodi okanye ukuzitywa;
- ukuhlanza;
- intlungu kwi-epigastrium namathumbu;
- ukudibanisa kwendoda;
- bronchospasm;
- dyspnea;
- ukuphefumula;
- i-aplastic anemia;
- purpura ye-thrombocytopenic;

- ukuma kwe-mucosa iso;
- ukungabonakali;
- ukunciphisa kwisixa sokukhupha amanzi okulila;
- i-conjunctivitis;
- ukukhanda kwesikhumba;
- urticaria;
- ukujuluka okukhulu;
- uvelwano lwesikhumba kwi-ultraviolet;
- i-hyperemia ye-epidermis;
- kwakhona kwakhona kwe-psoriasis;
- i-alopecia (ebuyiswayo);
- intlungu emva.
Ngokuqhelekileyo, emva kokumisa i-adrenoblocker, kukho "i-withdrawal syndrome" ngendlela yokunyuka okuthe ngqo kunye nokunyanisekileyo kwimixinzelelo yegazi, iziqhelo eziqhelekileyo ze-angina pectoris.
