Tus alpha-1 adrenergic receptor antagonists (tseem hu ua alpha-blockers ) yog tsev neeg ntawm cov neeg ua haujlwm khi rau thiab inhibit hom 1 alpha-adrenergic receptors thiab yog li inhibit cov leeg nqaij. contraction. Lawv cov kev siv loj yog rau kev kub siab thiab rau cov tsos mob benign prostatic hypertrophy benign prostatic hypertrophy Cov txiaj ntsig: Qhov zaus ntawm BPH, los ntawm hnub nyoog, yog raws li nram no: 41 txog 50 xyoo, 13.2%; 51 txog 60 xyoo, 20%; 61 txog 70 xyoo, 50%; 71 txog 80 xyoo, 57.1%; 81-90 xyoo, 83.3%. https://pubmed.ncbi.nlm.nih.gov › …
Kev kawm ua ntej ntawm qhov zaus ntawm benign prostatic hyperplasia thiab …
Cov tshuaj twg yog cais raws li adrenergic antagonist?
Ob qho piv txwv ntawm kev sib tw adrenergic antagonists yog propranolol thiab phentolamamine. Phentolamine yog kev sib tw thiab tsis xaiv α-adrenoreceptor antagonist. Propranolol yog β-adrenoreceptor antagonist.
Cov tshuaj dab tsi txhawb nqa adrenergic receptors?
Adrenergic tshuaj yog cov tshuaj uas txhawb nqa qee cov hlab ntsha hauv koj lub cev. Lawv ua qhov no los ntawm kev ua raws li kev ua ntawm cov neeg xa xov chemical epinephrine thiab norepinephrine lossis los ntawm kev txhawb nqa lawv tso tawm.
Vasopressors
- ephedrine.
- Yepinephrine.
- dopamine.
- phenylephrine.
- pseudoephedrine.
- Yoxymetazoline.
Cov tshuaj adrenergic cais li cas?
Adrenergic receptors, txwv tsis pub hu ua adreno-receptors, raug cais raws li alpha lossis beta receptors. Ob chav kawm ntxiv subdivide rau alpha-1, alpha-2, beta-1, beta-2, thiab beta-3. Alpha-1 thiab alpha-2 receptors ob leeg muaj peb subtypes.
Ob chav ntawm adrenergic agonists yog dab tsi?
Raws li receptor selectivity lawv yog ob hom: Tsis yog xaiv: tshuaj ua rau ib lossis ntau dua receptors; Cov no yog: Adrenaline (yuav luag tag nrho cov adrenergic receptors). Noradrenaline (acts on α1, α2, β1).
