Lub tsuas caveat kev txhawj xeeb kev sib ntaus nrog recurrent: nws yog assumed tias siv yeeb-tshuaj synonymous nyob rau hauv qhov kev txiav txim tsis tshua.

Lub tswv yim sab ntawm lub qhov teeb meem: txoj kev ntawm daim ntawv thov thiab ntau npaum

Ntsiav tshuaj "Valtrex" (analog, hais saum toj no, yog marketed nyob rau hauv cov ntsiav tshuaj daim ntawv thiab nyob rau hauv txhaj tshuaj / kua daim ntawv no) yuav tsum tau nqos tag nrho tsis muaj cuam tshuam daim nyias nyias kev ntseeg siab. Zaus mus kawm, thaum kawg ntev thiab ntau npaum ntawm cov tshuaj yog tswj los ntawm ib lub mob.

Piv txwv li, nrog herpes zoster hnub tus nqi yuav tsum tau rau cov ntsiav tshuaj 3 lub sij hawm nrog 2 chav nyob. Pom zoo nyob rau hauv cov ntaub ntawv no, qhov ntev ntawm kev kho mob - 7 hnub (lub caij nyoog lub sij hawm lub sij hawm txiav txim los ntawm lub mus kawm tus kws kho mob).

Ntawm no peb yuav tham txog plaub hnub kom tsawg, txhua tus uas yuav siv cov plaub tshuaj. Thiab xws li ib tug timetable yuav tau ua raws li peb lub hlis. Tab sis herpes simplex tus kab mob no amenable mus kho "Valtrex" nyob rau hauv ib tug ob peb hnub: mus txog kaum hnub, ib ntsiav tshuaj nyob rau hauv lub yav sawv ntxov thiab yav tsaus ntuj.

Cov kev txwv thiab ceev faj

Tshwj xeeb tej yam kev mob ntawm kev siv yuav tsum muaj cai nyob rau hauv cov kev kho mob nrog valacyclovir. Lub fact tias cov active tshuaj, ua ke nrog rau cov kev kho nyhuv tej zaum ntxias ib tug aggravation ntawm tus kab mob. Vim li no, tag nrho cov tshuaj, cov muaj pes tsawg leeg uas muaj ib tug kev cai tswjhwm tivthaiv, koj yuav tsum muab cov kev hloov nyob rau hauv ib tug neeg mob ( "Acyclovir" raws li analogous mus rau "Valtrex" raws li tus thawj siab subordinated rau txoj cai no).

Nyob rau hauv kev, lub irregularities nyob rau hauv lub chaw ua hauj lwm ntawm ob lub raum - ib lub teeb liab mus rau lub fact tias cov kev kho yuav tsum tau nrog los ntawm ib tug yuav tsum txoj kev cov kev tswj ntawm lub cev co theem (tshwj xeeb tshaj yog ib qho tseem ceeb rau cov neeg laus cov neeg mob).

Sij hawm raws li "Valtrex" lactation kev txaus cai nyob rau hauv exceptional mob.

Sab los "Valtrex" tshuaj

Txawm tias tus nqi thiab lub zoo tswv yim, "Valtrex", raws li, tseeb, muaj lwm yam yeeb tshuaj, muaj ob peb tsis zoo, manifested nyob rau hauv daim ntawv ntawm cov kev phiv reversible. Feem ntau ntawm lawv:

• mob taub hau, alternating nrog Kiv tauv hau;
• Ntau yam gastrointestinal mob (xeev siab, ntuav, raws plab, thiab lwm yam ...);
• haumxeeb mob thiab lub raum excretory raws;
• txo los yog, conversely, excessively siab laus;
• co, xa mus rau hauv convulsions;

Los ntawm txoj kev, tej analogue ( "Valtrex" feem ntau yog muab piv rau "Acyclovir") yog tseem imperfect: tom qab nws mus kawm, nyob rau hauv tas li ntawd mus rau saum toj phiv tshuaj cai nyob rau hauv cov neeg mob tej zaum causeless weariness tiv thaiv lub keeb kwm ntawm ua kom cov hepatic enzymes. Nyob rau hauv tas li ntawd, nws tau sau cais tus neeg mob thaum lub sij hawm lekarstva- "understudy" coj mus rau ib qho kev nce rau hauv lub concentration ntawm urea thiab creatinine.

Dlej analogue "Valtrex" los yog "Acyclovir"

Lw tus yeeb tshuaj, raws li koj paub, tsis muaj nyob. Txawm li cas los, nrug muaj feem luj qhov zoo thiab qhov tsis zoo ntawm cov tshuaj "Valtrex" (herpes xyuas rau lub siab lub ntsws thiab muab lus qhia load yog txog tib yam li cov lus, rau rau siab "Acyclovir"), nws tseem tau los xaus hais tias tag nrho pharmacological kev txawj ntse.

Yog hais tias tus cwj pwm haumxeeb parallels nrog cov "understudy", tus nqi ntawm uas yog peb mus rau plaub lub sij hawm tsawg dua, thiab lam zog cov suab tib yam, cov kom zoo dua tseem nyob nrog lub patented thawj. Lub hauv paus rau tsab ntawv no yog cov mechanism ntawm haum ntawm reactants.

Valaciclovir - puag tivthaiv "Valtrex" - yog tau kov yeej cov ntshav-hlwb barrier ua ntej transformation mus rau hauv acyclovir thiab li nyob twj ywm active kom txog rau thaum lub rooj sib tham nrog tus kab mob DNA; tib yam kom nquag plias siv yeeb-tshuaj cai tivthaiv pib ua ncaj qha mus rau qhov pib ntawm metabolic dab, uas nws loses ib co tshuaj tej zaum. Thiab tsis tau ua tsaug rau ib tug kuas pharmacological kinetics ntawm cov tshuaj nyob rau hauv cov lag luam tawm npe "Acyclovir" zoo stands cim.

Tab sis tham txog ib tug ua tiav kev zoo sib thooj nrog kim tshuaj ntau pheej yig Generics tsis tau. Teej tug mus rau txawv nqi pawg txiav txim los ntawm lub nram qab no:

• degree ntawm purification reagents thiab kev phiv;
• hauv lub xub ntiag / tsis tuaj kawm ntawv ntawm ancillary Cheebtsam;
