Antacids yog ib pawg tshuaj uas txo cov acidity ntawm lub plab. Cov nyhuv no yog ua tiav los ntawm adsorption lossis neutralization ntawm hydrochloric acid nyob rau hauv cov kua txiv hmab txiv ntoo. Nws yuav tsum tau muab sau tseg tias antacids rau feem ntau muaj ib tug adsorbing thiab neutralizing nyhuv.
Feem ntau qhov kev txiav txim siab nruab nrab yog qhov raug rau cov tebchaw ntawm qee cov hlau alkali. Cov no suav nrog, tshwj xeeb, precipitated calcium bicarbonate, sodium bicarbonate, yooj yim magnesium carbonate, thiab magnesium oxide. Ion-exchange resins thiab qee cov khoom siv txhuas muaj cov nyhuv adsorbing. Aluminium oxide, phosphate, hydroxide, tshwj xeeb tshaj yog nyob rau hauv daim ntawv colloidal, kuj muaj cov nyhuv enveloping, thaum nce kev tiv thaiv ntawm lub plab mucosa, txo cov secretory kev ua si nyob rau hauv lub txiav.
Antacids, los ntawm kev nce pH ntawm cov ntsiab lus ntawm lub plab mus rau 4.5, txo qis kev ua haujlwm peptic ntawm cov kua txiv hmab txiv ntoo. Cov tshuaj uas muaj txhuas ua rau inhibition ntawm pepsin kev ua si, yog li txo qhov tseem ceeb ntawm peptic yam nyob rau hauv lub tsim ntawm ulcers thiab kev saib xyuas ntawm inflammatory dab nyob rau hauv lub mucosa. GIT. Colloidal aluminium antacid npaj (tshwj xeeb tshaj yog nyob rau hauv daim ntawv ntawm gels - Phosphalugel, Almagel) tsim ib hom kev tiv thaiv txheej ntawm mucosa. Cov txheej no adsorbs ntau yam mucosal puas tshuaj muaj nyob rau hauv txoj hnyuv los yog plab kab noj hniav, nrog rau co toxins, microbial lub cev, bile acids.
Antacids. Classification
Tshuaj sib txawv hauv lawv lub peev xwm los ua kom tsis muaj hydrochloric acid. Yog li, piv txwv li, ib gram ntawm sodium bicarbonate neutralizes txog ib puas thiab nees nkaum milliliters ntawm acid, ib gram ntawm magnesium trisilicate - 155 ml, ib gram ntawm precipitated calcium carbonate - 200 ml, thiab hais txog. Ntawm cov neeg ua haujlwm, sodium bicarbonate muaj qhov ua haujlwm tsawg tshaj plaws, magnesium oxide muaj qhov siab tshaj plaws.
Antacids tuaj yeem ua haujlwm tau ob peb teev. Lub sijhawm ua haujlwm tuaj yeem nce ntxiv nrog cov tshuaj anticholinergic, H-2 histamine blockers thiab lwm yam tshuaj uas txo qis kev ua haujlwm hauv plab.
Ntawm cov kev sib raug zoo ntawm cov pab pawg raws li kev txiav txim siab, ib tus yuav tsum tawm cov tshuaj xws li Maalox, Alamag, Phosphalugel.
Cov tshuaj kawg yog cov tshuaj colloidal. Cov tshuaj yog noj ntawm qhov ncauj. Nws raug sau tseg rau dyspepsia, gastritis - ua ntej noj mov, rau qhov txhab - tom qab noj mov hauv ib teev lossis ob teev, thiab yog tias mob tshwm sim - tam sim ntawd. Nrog reflux esophagitis - ua ntej mus pw tom qab noj mov, thiab nrog kev ua haujlwm tsis zoo hauv cov hnyuv loj - hmo ntuj thiab sawv ntxov ntawm lub plab khoob.
Maalox tshuajMuaj nyob rau hauv daim ntawv ntawm chewable ntsiav tshuaj, hmoov thiab suspension. Cov khoom muaj magnesium hydroxide thiab algeldrate. Feem ntau pom zoo ib mus rau ob ntsiav tshuaj lossis ib tablespoon ntawm kev ncua ib hnub.
txhais tau tias "Alamag" yog tsim nyob rau hauv daim ntawv ntawm kev ncua. Qhov pom zoo ib koob tshuaj rau tus neeg laus yog ib diav (teaspoon).
