Atropin tamasuak ubek antimuskarinik (masih dalam kalompok antikolinergik) nan bakarajo jo maambek saraf parasimpatis.[7] Karajo atropin ko dapek mamunculkan efek sampiang yaitu muluik kariang, pupil maleba, urin tatahan, kabobolan, sarato danyuik jantuang capek. Dek efek sampiangnyo nan ado pado mato, ubek ko indak buliah diagiah pado urang jo glukoma suduik tatutuik. Untuak mandeh nan manganduang alun ado panalitian nan manjalehan bahayonyo, tapi buliah diagiah untuak mandeh nan manyusui.[8]
Indikasi
suntiangAtropin marupokan ubek antimuskarinik sainggo dapek dipakai untuak maambek produksi aia liua katiko pambadahan. Hal iko batujuan supayo pasien pambadahan nan sadang dibius sarato diintubasi (mamakai alaik bantu angok) indak taaspirasi atau tamasuak aia liau ka saluran angoknyo.[9][10]
Atropin baguno juo untuak maatasi karacunan, baiak dek gas saraf ataupun dek pestisida, walau indak sadoalah pestisida bisa. Pado kondisi karacunan, atropin bakarajo jo maambek asetilkolin pado reseptor muskarinik. Atropin diagiah sabagai respon capek maatasi karacunan. Pado kondisi parang, tantara kadang bahadapan jo ko sarangan gas saraf cando tabun, sarin, soman, sainggo digunakan atropin suntiak dalam wujuik autoinjektor (alaik suntik nan lansuang pakai jo dosis nan tasadio). Atropin acok digunokan basamoan jo pralidoksim klorida. Pado karacunan nan maakibatkan gangguan lokal, cando gangguan mato atau saluran angoko, atropin indak diindikasikan.[9]
Atropin dipakai juo pado kondisi danyuik jantuang malambek (bradikardi) sabagai terapi garih partamo. Diindikasikan katiko ado gangguan struktur pado sistem infranodul atau kok danyuik jantuang kurang dari 50 kali/minik jo tando vital indak stabil. Rato-rato 20% urang bradikardia disababkan dek gangguan hantaran listrik dalam jantuang. Atropin buliah dipakai barulang pado pasien ko asalai ado pabaikan. Pado anak-anak, paralu dicari tau panyabab bradikardianyo. Umumnyo jarang disababkan kalainan jantuang, labiah acok disababkan dek hipoksia atau hipoventilasi. Kok pasian anak maalami bradikardia jo angok nan cukuik rancak, atropin dapek diindikasi.[10][11][12]
Atropin dipakai pulo untuak masalah mato. Pasien nan tibo jo kaluahan padiah di mato dek uveitis atau mato taraso buran dek ambliopia, buliah diagiah atropin. Atropin maagiah efek pupil maleba sainggo baguno pulo untuak tindakan diagnostik. Efek pupil maleba ko disabuik jo efek midriatik. Dek efek iko, pasien jo glukoma suduik tatutuik dikontraindikasikan dek efeknyo nan mampaburuak.[13][14][15]
Mekanisme karajo
suntiangAtropin adolah ubek antimuskarinik nan bakarajo untuak maambek reseptor asetilkolin postganglion sarato vagolitik lansuang (direct vagolytic). Hal iko mambuek efek parasimpatis taambek pado otot polos. Efek akhianyo maningkekan ransangan simpatis nan ditandoi jo maningkeknyo kaluaran jantuang (cardiac output) sarato efek sampiang lain takaik antimuskarinik.[3]
Efek sampiang
suntiangEfek sampiang atropin pado umumnyo bahubuangan jo sipaiknyo nan antimuskarinik di antaronyo muluik kariang (xerostomia), pandangan buram, silau dek cahayo (photophobia), danyuk jantuang capek (takikardia), kulik sirah jo angek. Kabobolan, kanciang tatahan, sarato indak bakaringek (anhidrosis) dapek tajadi khususnyo pado populasi barisiko cando urang-urang gaek. Pado kasus nan sarik, delirium (pikun) atau koma dapek tajadi. Reaksi hipersensitivitas dapek tajadi dan biasonyo tabateh pado kulik.[16][17]
Atropin dapek mangurangi absorpsi dari mexiletin nan dapek ditagah jo kombinasi metoklopramid jo atropin sabalun tindakan anestesi.[18]

Putting special eye drops in the stronger eye. A once-a-day drop of the drug atropine can temporarily blur near vision, which forces the brain to use the other eye. For some kids, this treatment works as well as an eye patch, and some parents find it easier to use (for example, because young children may try to pull off eye patches).
