Adrenergic antagonists yog feem ntau siv rau kab mob plawv. Cov adrenergic antagonists yog dav siv los txo cov ntshav siab thiab txo cov ntshav siab. Cov no yeeb ncuab tau muaj pov thawj los daws qhov mob los ntawm myocardial infarction, thiab tseem qhov infarction loj, uas cuam tshuam nrog lub plawv dhia.
Hais txog qhov no, ua li cas adrenergic blockers ua haujlwm?
Alpha thaiv txo cov ntshav siab los ntawm kev ua kom cov tshuaj norepinephrine los ntawm kev nruj cov leeg hauv cov phab ntsa ntawm cov hlab ntsha me thiab leeg. Vim li ntawd, cov hlab ntsha tseem qhib thiab xis nyob. Qhov no txhim kho cov ntshav ntws thiab txo cov ntshav siab.
Ib tus kuj tseem yuav nug tau, dab tsi yog qhov tshwm sim feem ntau ntawm beta blockers? Cov kev mob tshwm sim ntawm beta blockers suav nrog:
- Kiv taub hau.
- Tsis muaj zog.
- Kev tsaug zog los yog qaug zog.
- Tes txias thiab txhais taw.
- Qhov ncauj qhuav, tawv nqaij, lossis qhov muag.
- Mob taub hau.
- Chim plab.
- Zawv plab los yog cem quav.
Yooj yim li ntawd, adrenergic thaiv cov tshuaj ua dab tsi?
Beta thaiv , tseem hu ua beta- adrenergic thaiv cov neeg sawv cev , yog cov tshuaj uas txo koj cov ntshav siab. Beta thaiv ua haujlwm los ntawm thaiv qhov cuam tshuam ntawm cov tshuaj epinephrine, tseem hu ua adrenaline. Beta thaiv ua rau koj lub plawv dhia qeeb dua thiab tsis muaj zog, uas txo cov ntshav siab.
Yuav ua li cas thaum adrenergic receptors raug thaiv?
Blockade ntawm α1 adrenergic receptors inhibits vasoconstriction, thiab yog li ntawd vasodilation nyob rau hauv ob leeg arteriolar tsis kam tiv thaiv cov hlab ntsha thiab cov leeg tuaj yeem tshwm sim. Kev poob ntshav hauv ntshav siab nyob ntawm qib ntawm lub suab sib khuv xim (siab dua hauv qhov sawv ntsug thiab txoj haujlwm supine).

Yuav muaj dab tsi tshwm sim thaum koj tsis noj beta blockers?
Thaum koj noj beta blocker tsis tu ncua, lub cev siv rau nws. Yog li, kev siv tshuaj sai sai qee zaum tuaj yeem ua rau muaj teeb meem xws li ua tsis taus pa, nce ntshav siab, lossis rov mob angina mob ntxiv. Yog tias koj xav tau kom tsis txhob noj beta blocker ces koj tus kws kho mob yuav qhia kom txo qis ib koob tshuaj
Dab tsi yog qhov muag tee yog beta blockers?
Piv txwv ntawm beta-blockers siv hauv kev kho mob glaucoma yog Timoptic XE (Merck), Istalol (ISTA) thiab Betoptic S (Alcon). Alpha-adrenergic agonists. Cov tshuaj no ua haujlwm los ntawm kev txo tus nqi ntawm cov dej lom zem ntau lawm thiab tuaj yeem siv ib leeg lossis ua ke nrog lwm cov tshuaj tiv thaiv kab mob glaucoma qhov muag
Calcium channel blockers thiab beta blockers puas tuaj yeem noj ua ke?
Nyob rau hauv lub xyoo caum dhau los, txoj kev kho rau ruaj khov angina pectoris tau nthuav dav heev nrog kev qhia txog cov calcium-channel blockers. Cov teebmeem hemodynamic ntawm nifedipine thiab beta-blocker feem ntau ua haujlwm zoo ua ke; Txawm li cas los xij, cov kev mob me me tsis tshua muaj tshwm sim
Dab tsi yog Beta blockers muaj kev ua haujlwm ntawm lub cev sympathomimetic?
Qee cov beta blockers (piv txwv li oxprenolol, pindolol, penbutolol, labetalol thiab acebutolol) muaj cov kev ua sympathomimetic (ISA). Cov neeg ua haujlwm no muaj peev xwm ua rau qis qis agonist kev ua haujlwm ntawm β-adrenergic receptor thaum tib lub sijhawm ua tus receptor site antagonist
Dab tsi yog Nondepolarizing neuromuscular blockers?
Neuromuscular thaiv cov neeg ua haujlwm ua haujlwm ntawm qhov sib txuas neuromuscular. Muaj ob hom, depolarizing thiab nondepolarizing. Depolarizing nqaij relaxants ua raws li ACh receptor agonists. Nondepolarizing nqaij relaxants ua raws li kev sib tw antagonists. Lawv khi rau ACh cov neeg txais tab sis tsis tuaj yeem ua rau qhib cov channel ion
