I-Dexamethasone yisigqirha esaziwayo ixesha elide kumayeza, esoloko imiselwe kwaye i-ophthalmologists ngendlela yamathambo asehlo. Isichengiselwano samachiza kwi-ophthalmology sisetyenziselwa phezulu, oko kukuthi, umphumo wayo wokunyanga ujoliswe ekuphumeleleni kwinqanaba elithile okanye inxalenye yomzimba. Kwaye uthetha nje, amaconsi kufuneka angcwatywe kwiso, kwaye umphumo wonyango kuwo wonke umzimba uya kuhlaselwa.
Isenzo se-Pharmacological yesilwanyana
I-Dexamethasone ibhekiselele kumalungiselelo e-glucocorticosteroid, okuyi-steroids. I-Steroids yinto enezinto eziphezulu zezinto eziphilayo, ukulawula umgangatho wesimo kunye nemisebenzi ethile yomzimba emzimbeni womntu.
Impembelelo eyahlukileyo ye-glucocorticosteroids emzimbeni womntu ilandelayo:
- i-antiallergic effect;
- isenzo sokuchasa;
- ukulwa noxinzelelo;
- ukwanda kweemetabolism;
- isenzo esilawula umzimba;
- impembelelo echasayo.
I-Dexamethasone yinto yokwenza izinto ze-glucocorticosteroid kunye nendlela yokwehla kwamehlo, ngokwemiyalelo, inika umonakalo osheshayo wokuvuvukala, isenzo esichasayo kunye nesenzo esichasayo. Iphulo elilodwa nje leziyobisi, elityelwe kwiso ngalinye, liqinisekisa ukuba liphumelela kwi-iriyure eziyi-8.
Amaconsi angcwatyelwa ngokuthe ngqo kwi-conjunctiva, igobolondo eqaqambileyo efihla amehlo ukusuka ngaphandle. Kububomvu beempahla zesiqhagamshelo esithetha ngazo "ngamehlo obomvu". Ukufikelela kwi-conjunctiva, iliso lehla ukusuka ku-dexamethasone isifo sengqondo esheshayo singena kwi-epithelium kwaye indawo ephilileyo yamehlo igcwele ukuxinwa kweziyobisi eziyimfuneko yokunyanga. Kwaye phambi kwenkqubo yokuvuvukala, isilwanyana singene kwiimeko zasemanzini ngokukhawuleza. Inkunkuma isetyenziselwa esibindi kwaye ikhutshwe emzimbeni ngeemfesi.
Iimpawu zokuqeshwa kweDexamethasone
Iliso lihlahla iDexamethasone 0.1% lichazwe ngezi zilandelayo:
- conjunctivitis;
- i-keratitis (ukuvuvukala kwe-cornea yelihlo);
- i-blepharitis (isifo sokuvuba seentloko zeentloko);
- i-scleritis (ukuvuvukala kwe-sclera);
- i-chorioretinitis (ukuvuvukala kwe-choroid kunye ne-retina);
- uveitis (ukuvuvukala kwe-choroid yamehlo);
- iridocyclitis (ukuvutha kwe-iris kunye nomzimba we-eyeballball);
- neoptic neuritis;
- ukukhathazeka kwamehlo (kuquka ukutshisa);
- ixesha lokuhamba emva (ukuhlinzwa kwamehlo).
Ingaba isichengiselwano kunye nokuchasene ngokuqinileyo malunga nokuqeshwa:
- izilonda zefungal zamehlo;
- umonakalo wegciwane;
- ukusuleleka kwezifo;
- i-glaucoma (i-clouding ye-lens);
- uxinzelelo lwe-intraocular;
- ukutyumba kwe-cornea;
- isifo sofuba ;
- Isikolo sokufunda esikolweni kubantwana (kwiimeko ezinxamisekileyo, iliso lehla iDexamethasone lingcwatyelwa empumlweni yabantwana, kodwa emva kokuqeshwa kogqirha);
- isenzo esichaphazelekayo kwiimpawu zesilwayo;
- ixesha lokuncelisa;
- Ukukhulelwa (iliso lehla iDexamethasone lingasetyenziselwa ukukhulelwa, ngaphandle kokuba iinzuzo ezisuka ekusebenziseni kwazo zidlula umngcipheko kumntwana, ukuba unyango lungadluli iveki enye).
Indlela yokusebenzisa i-dexamethasone?
Amaconsi kunye neDexamethasone imiselwe ngokuphindaphindiweyo ngendlela efanayo - 1-2 ahla ehlweni ngalinye kathathu ngosuku, ngexesha elifanayo. Kwiifom ezinzima zokuqhaqhazela, ngezifo ezithile, ugqirha unokwenza enye ikimu. Xa zisetyenziswe, izigulane zihlala ziqaphela ukuvutha komlilo emehlweni emva kokugxilwa. Oku kuyisenzo esivamile kwixabiso kwaye, ukuba ukutshiswa komlilo kudlulayo ngokukhawuleza, akufuneki ukuba ukhansele isilwanyana.
