Sympathomimetics stimulate lub plawv los ntawm activating beta-adrenergic receptors, thiab ua rau vascular du nqaij contraction thiab vasoconstriction los ntawm activating alpha-adrenergic receptors.
tshuaj sympathomimetic ua dab tsi?
Sympathomimetic tshuaj mimic lossis txhawb lub paj hlwb adrenergic, thiab lawv tuaj yeem ua rau ntshav siab nce siab, tshwj xeeb tshaj yog cov neeg mob ntshav siab.
Yuav ua li cas yog cov kev phiv rau sympathomimetics?
- Tremor (feem ntau cov kev mob tshwm sim), ntxhov siab., insomnia., diaphoresis.
- Hypotension. (vim peripheral. vasodilation.) thiab. reflex tachycardia.
- YMetabolic cuam tshuam: hyperglycemia., hypokalemia.
Yuav ua li cas enzyme metabolize cov tshuaj sympathomimetic?
inhibition ntawm norepinephrine metabolism tuaj yeem tsim cov teebmeem sympathomimetic. Norepinephrine feem ntau yog metabolized los ntawm enzyme monoamine oxidase, cov tshuaj monoamine oxidase inhibitor (MAOI) tuaj yeem ua rau muaj kev cuam tshuam zoo li no.
Dab tsi yog qhov txawv ntawm sympathomimetic thiab Sympatholytic tshuaj?
A tshuaj uas txhim kho adrenergic muaj nuj nqi yog lub npe hu ua sympathomimetic tshuaj, whereas tshuaj uas cuam tshuam adrenergic muaj nuj nqi yog ib tug sympatholytic tshuaj.
