Central sympatholytic tshuaj txo cov ntshav siab feem ntau los ntawm stimulating nruab nrab α2-adrenergic receptors hauv lub hlwb cov chaw, yog li txo qis kev ua haujlwm ntawm lub paj hlwb thiab kev tso tawm ntawm norepinephrine rau lub plawv thiab cov hlab ntsha ncig.
Kuj paub, Sympatholytics ua dab tsi?
A sympatholytic (lossis mob siab rau) tshuaj yog tshuaj uas tawm tsam qhov nqes dej ntawm postganglionic cov hlab ntsha ua haujlwm hauv lub cev ua haujlwm sab hauv los ntawm kev mob siab rau lub paj hlwb (SNS). Lawv yog qhia rau ntau yam haujlwm; piv txwv li, lawv tuaj yeem siv ua antihypertensives.
Kuj Paub, dab tsi yog central alpha agonists? Central alpha agonists tau siv los kho ntshav siab, opioid vam khom, quav dej quav cawv, cov tsos mob menopause, ADHD, spasticity, thiab fibromyalgia. Lawv ua haujlwm los ntawm kev txo cov ntshav siab, txo cov kub kub, thiab txo cov tsos mob ntawm kev tshem tawm, thiab tswj tus cwj pwm impulsive.
Raws li qhov sib txawv ntawm cov tshuaj sympathomimetic thiab Sympatholytic yog dab tsi?
Adrenergic tshuaj , ib yam ntawm ntau yam tshuaj uas ua piv txwv lossis cuam tshuam nrog kev ua haujlwm ntawm kev mob siab rau lub paj hlwb los ntawm kev cuam tshuam rau kev tso tawm lossis kev ua ntawm norepinephrine thiab epinephrine. Adrenergic tshuaj uas tsim los yog inhibit cov teebmeem no hu ua sympathomimetic cov neeg sawv cev thiab sympatholytic cov neeg sawv cev, feem.
Dab tsi yog centrally ua antihypertensives?
Cov classic centrally ua antihypertensives xws li clonidine, guanfacine thiab alpha-methyl-DOPA (dhau los ntawm nws cov metabolite nquag alpha-methyl-noradrenaline) ua rau cov khoom siv sab hauv sympathoinhibition thiab poob hauv ntshav siab vim yog alpha2-adrenoceptor txhawb zog hauv lub paj hlwb.
