Mechanism of Action
Decongestants txhawb cov alpha -adrenergic receptors los txwv cov hlab ntsha hauv lub qhov ntswg mucosa. Qhov no txo qis qhov o thiab tsim cov hnoos qeev hauv lub qhov ntswg los ntawm qhov mob khaub thuas, mob sinusitis, thiab ua xua ua xua ua xua.
Raws li, cov piv txwv ntawm decongestant yog dab tsi?
Common decongestants muaj xws li:
- Afrin, Dristan, Vicks Sinex (oxymetazoline)
- Sudafed PE, Suphedrin PE (phenylephrine)
- Silfedrine, Sudafed, Suphedrin (pseudoephedrine)
Kuj Paub, yog vim li cas cov tshuaj tua kab mob ua rau vasoconstriction? Qhov ntswg decongestants yog vasoconstrictors uas yog koom nrog chav kawm tshuaj pharmacological sympathomimetic amines. Lawv ua lawv qhov kev txiav txim siab thawj zaug los ntawm kev ua kom alpha-adrenergic receptors ntawm cov hlab ntshav ntawm lub qhov ntswg mucosa. Qhov no tshwm sim hauv vasoconstriction , uas txo cov ntshav ntws los ntawm lub qhov ntswg mucosa thiab ua rau cov nqaij mos.
Ib sab ntawm no, qhov kev txiav txim ntawm phenylephrine yog dab tsi?
Phenylephrine yog ib qho ncaj qha-ua sympathomimetic amine tshuaj muaj feem cuam tshuam nrog adrenaline thiab ephedrine nrog lub zog vasoconstrictor. Phenylephrine yog post-synaptic alpha-adrenergic receptor agonist uas ua rau vasoconstriction, nce systolic/diastolic pressures, reflex bradycardia, thiab mob stroke.
Dab tsi yog qhov cuam tshuam rov qab los ntawm decongestants?
Ib qho tsawg dua ntawm tus mob no yog rhinitis medicamentosa, tseem hu ua thim rov qab kev khov. Nws tuaj yeem tshwm sim thaum koj siv lub qhov ntswg ntau dhau decongestant . Hloov chaw ua rau koj zoo siab, cov tshuaj ntxiv ua rau koj lub qhov ntswg puas tsuaj.

Dab tsi yog 3 lub tswv yim ntawm kev nqus ntawm cov as -ham?
Digestive secretions thiab nqus dej. Kev nqus yog txheej txheem nyuaj, uas cov as -ham los ntawm cov zaub mov zom zom tau sau. Kev nqus tau tuaj yeem tshwm sim los ntawm tsib lub tswv yim: (1) kev thauj mus los, (2) passive diffusion, (3) txhawb kev nthuav dav, (4) kev thauj mus los (lossis kev thauj mus los zaum ob), thiab (5) endocytosis
Lub tswv yim ntawm kev txiav txim siab ntawm glycosides hauv lub plawv yog dab tsi?
Cardiac glycosides yog chav kawm ntawm cov organic sib txuas uas ua rau lub zog tawm ntawm lub plawv thiab nce nws qhov kev cog lus los ntawm kev ua haujlwm ntawm cellular sodium-potassium ATPase twj tso kua mis
Lub tswv yim ntawm kev txiav txim ntawm atenolol yog dab tsi?
Atenolol belongs rau chav kawm ntawm cov tshuaj hu ua beta-blockers. Nws ua haujlwm los ntawm kev thaiv qhov kev txiav txim ntawm qee yam tshuaj hauv koj lub cev, xws li epinephrine, ntawm lub plawv thiab cov hlab ntshav. Cov nyhuv no txo qis lub plawv dhia, ntshav siab, thiab mob plawv
Daim ntawv teev npe twg piav txog plaub qhov chaw uas tus kws kho mob yuav txiav txim siab siv plaub lub ntsiab lus mus rau kev txiav txim siab ncaj ncees?
Nyob rau hauv lub moj khaum no, tag nrho cov teeb meem kev ncaj ncees raug tshuaj xyuas nyob rau hauv cov ntsiab lus ntawm plaub lub ntsiab lus: kev kho mob, kev nyiam ntawm tus neeg mob, lub neej zoo, thiab cov yam ntxwv ntawm cov ntsiab lus (piv txwv li, kev sib raug zoo, kev lag luam, kev cai lij choj, thiab kev tswj hwm)
