Vasodilators.

daroogada Vasodilator - daroogada isagoo talaabo myorelaxant on derbiga vascular, taasoo keentay in Lumen vascular kordhiyay. Kooxdaan daroogada waxaa inta badan loo isticmaalaa sida hypotensive iyo xanuunka (saaraysaa dabac) therapy.

Vasodilators loo qaybin karaa beta-blockers, Nitrate, celiyeyaasha ACE iyo receptor.

hab ay of tallaabo of B-blockers hoos u dhigay xiritaanka ee receptors durugsan ee muruqa wadnaha uga timid tallaabada catecholamines ah. Sidoo kale waxay saamayn ku yareeya tirada wadne halkii daqiiqo, taasoo keentay in soo saarka wadnaha hoos. Go'doominta ee receptors durugsan keenaysaa in hoos u dhac in isticmaalka oxygen myocardial iyo cadaadiska dhiigga.

Beta-blockers saamayn antiarrhythmic, iyo sidoo kale joogsada waxqabadka of renin ee plasma dhiigga. Kooxdaan wakiilada sidoo kale waxay leedahay saameyn cardioprotective, i.e., Waxay ka caawisaa celin miokadiotsitov. Beta blockers-qaybsan yihiin aan la xushay oo la xushay (hawlaha sympathomimetic kala go'lahayn iyo waxa aan).

The wakiilada ugu weyn ee:

1. Propranolol iyo nadolol (iyada oo aan waxqabad sympathomimetic jaleelada).
2. Pindolol iyo oxprenolol (la joogitaanka hawlaha kala go'lahayn).
3. Bisoprolol, Betoksolol, atenolol (xulashada).

Waxaa jira tiro ka mid ah cudurada, taas oo muujinaysaa isticmaalka beta-blockers:

- cudurada wadnaha, kog;

- dhibaatada hypertension halbowlaha;

- heerka xadgudub (tachycardia);

- wadnaha,

- MI hore;

- dhanjafka.

Waxaa jira Gudigga qaarkood in magacaabidda beta-blockers inta ay uurka leedahay, sonkorowga iyo nuujinta, laakiin waxa ay macnaheedu ma aha in ay ku hoos jira xaalad kuwani waa waa u. sababo Absolute in ay caga daroogada waa kuwan:

- cudurada sambabada obstructive chronic;

- cudurka dhuumaha ugu sarreeya;

- block wadnaha 2-3 digrii.

Dhibaatooyinka ay keento in blockers ballanta:

- xanuunada wareegga dhiigga ee foomka of kabuubyo ama jirka qabow, misko hawomareenno badan.

- hemogram xadgudub (kordhay heerka sonkorta dhiigga, muuqaalka kore ee HOL ah).

Vasodilators group amooniyam - mid ka mid ah daroogada ee ugu horeysay ee loo isticmaalo daweynta ee hypertension, ischemia myocardial, dhibaatooyinka. Ay hab of tallaabo waa in la yareeyo qaadashada ee oxygen ee myocardium ah, taasoo keentay in la ballaariyo xididdada durugsan iyo hoos u dhiig soo laabtay arooriyaha. diyaarinta Kuwani ka qayb qaatay sii kordhaya socodka dhiigga wadnaha sabab u vasodilation, oo sidaas daraaddeed, caawin dubaaxin ee halbowleyaasha wadnaha.

Tirada Vasodilators nitroglycerin looma isticmaali karo in joogitaanka hemorrhage galay maskaxda iyo kacsantahay cadaadis intracranial, sida in xaaladda this, waxay sii xumayn kaliya darnaanta cudurka.

Vasodilators Waayo, madaxayga waxaa inta badan loo isticmaalaa jaf oo dabac vascular. Xaaladahan oo kale, waxaa fiican in la isticmaalo group beta-blockers, waxay leeyihiin saamayn myorelaxant calaamadeysan on derbiga vascular

Kooxdu waxay dambe ee daroogada - daroogada waa vasodilators, oo ka tirsan fasalka of celiyeyaasha ACE. Waxyaabahani waxaa badanaa loo isticmaalaa in Wadnaxanuun myocardial, hypertension, cillad ah ventricle bidix ee wadnaha. Sababo in ay u socdeenna yihiin uurka, giperkaliyemiya, stenosis halbowlaha kelyaha.

hab ay of tallaabo daroogada waa muujinta saamaynta neurohumoral (kororka hawlaha nidaamka kallikrein-kinin ah, hagaajinta factor endothelium-nasto ah), iyo saamaynta dheefshiidka (action antioxidant, kordheen heerarka potassium, dareenka sii kordhaya ee unugyada durugsan).

Daawo vasodilation waxaa badanaa loo isticmaalaa in ku dhaqanka caafimaad oo casri ah oo uu leeyahay saamayn togan ku-daweynta ee cudurada of xididdada dhiigga ee madaxa iyo wadnaha, iyo sidoo kale ay goobjoog ka ahaayeen nudaha wadnaha ischaemic in geeddi-socodka.
