Blockers tsa beta

Lithethefatsi hore ho matleng a sehlopha sena sa dintho sebelisoa ho tšoara mogodisa lefu la pelo: gogoga lefu la pelo (ho akarelletsa le a hlobaetsang le myocardial infarction, prophylaxis tsa pectoris angina), kgatelelo ya madi, tachyarrhythmias, ho hloleha foleng pelo.

blockers Beta sebetsa ba khahlanong le lōna e le tlhōlisano ea noradrenaline, adrenaline le lintho tse ling hore ba na le thepa ea tsa beta adrenoceptor agonists on.

Bohlokwa ba tsamaiso ya metsoako sehlopheng sena itšetlehile ka boemo ba tsamaiso ea methapo le kutloelo-bohloko. Ka e leng keketseho ea tsamaiso ena, dintho behang nka khato ka 'mele oa motho. Le sekgoeng. Ka ho khetheha, katleho ea bona ho eketsa le pathologies tse sa tšoaneng tsa pelo, tse tsamaea le maemo a sithabetsang, thyrotoxicosis, batho ba tsubang (bokoali eketseha le kutloelo-bohloko molumo).

Moriana dintho fanoeng lihlopha diokobatsi ke tsa mefuta e meraro: a tsoakiloeng, bao e seng khetha le khetha. Beta blockers: atenolol, metoprolol, acebutolol, bisoprolol, esmolol - ho matleng a mofuta oa boraro. lithethefatsi bao e seng khetha emeloang ke propranolol, nadolol, pindolol, penbutalolom, timolol, oxprenolol, sotalol. Ho kopanya blockers: labetalol, carvedilol.

Le ka sehloohong cardiac bolwetse, eo ho eona a sebelisa blockers tsa beta - lefu ischemic pelo. The mochine ea nkang khato ea dintho ke tsa beta adrenergic thibela likepe, e isang ea fokotseha tsa mesebetsi pelo: contractility, conduction, excitability, automatism. Phello ke phokotso ea pelo, e leng ke ea fokotseha ka lebelo leo pelo, setorouku bophahamo ba modumo le khumo cardiac. Myocardial tlhokeho oksijene e fokotsehile haholo, 'me kahoo ho etsa bonnete ba e atlehang ho thibela litlhaselo tse angina. Lithethefatsi tsa sehlopha sena ho fokotsa kotsi ya lefu la tšohanyetso ka bakuli ba a utloa bohloko myocardial infarction.

Bakeng sa cupping tachyarrhythmias ba a boela a sebelisa adrenoblokatorry tsa beta. The fokotseha ka lebelo leo pelo, slowing tsa conduction atrioventricular hlalosa phello phekolo. A e le hantle ho feta phatlalletsoang ea lithethefatsi e hlokomela ka ho ba teng ha arrhythmias atrial.

Moriana dintho tseo na tsa beta emisang ketso e matleng a hae ho e 'ngoe ea litlelase tse hlano tsa mahlahana antihypertensive. Ba li sebelisetsoa ho tšoara sethaleng efe kapa efe ya kgatelelo ya madi, hammoho le bakeng sa kalafo ya mofuta bontshang matshwao ya lefu lena. The mochine ea nkang khato ea blockers tsa beta e entsoe ka metsoako e mene: fokotswa pelo mosebetsi, hatelloang ba tsamaiso renin-angiotensin, ho theola molumo oa setsi vasomotor, fokotsa kakaretso ea ho hanyetsa pheriferale ea mali.

Bakeng sa kalafo ya ho hloleha blockers foleng pelo sebelisitsoeng ho eona. Sehlopha sena sa ho sebelisa lithethefatsi e tlosoa tšusumetso e ka tsela e feteletseng ea tsamaiso le kutloelo-bohloko ke tšohile ka ho teba. Sena se fokotsa liphello tse bohloko tsa epinephrine le norepinephrine ka pelo, decreases mosebetsi oa receptors tsa beta adrenergic, slowing ho otla ha pelo. Leha ho le joalo, ho sebelisa ya tekanyetso ka tsela e feteletseng ea lithethefatsi ka 'na boima ba' mele ho hlōleha ya data pelo.

blockers Beta ba a boela a sebelisa ka tsela e atlehang bakeng sa ho phekoloa bulehileng-angle glaucoma. Ba thusa ho fokotsa mokelikeli secretion ea ciliary mele. Kahoo, fokotseha khatello intraocular le matšoao a lefu le nyamela.

Bakeng sa kalafo la litlhaselo migraine sebediswa metoprolol, atenolol, timolol le nadolol. ketso ea bona e hlalosa ka ho sa spasm ea methapo ea bokong, lithethefatsi mosebetsi agonistic ka receptors serotonin ka tsamaiso ea methapo e bohareng.
