Cov Ntawv Thov
Diprophylline (CAS 479-18-5) yog qhov chaw saib xyuas Xanthine feem ntau yog siv nyob rau hauv kev kho mob ua pa xws li cov mob ntsws ua pa xws li mob ntsws ua paug. Nws ua raws li tus bronchodilator, pab los so cov leeg du ntawm cov hlab pa thiab txhim kho airflow. Hauv cov chaw kuaj mob, diprophylline yog muab cov lus qhuab qhia lossis kev txhawb nqa rau nws cov kev cuam tshuam rau kev tswj hwm bronchospasm thiab txhim kho kev ua haujlwm ua pa. Dhau ntawm kev kho ncaj qha, nws tseem siv hauv cov kws tshawb fawb ntawm kws tshuaj tshawb fawb raws li kev siv Xanthine derivatives, lawv cov tshuab kev ua hauv cov pa ua pa thiab cov pa plawv.
Cov txiaj ntsig
Cov txiaj ntsig ntawm diprophylline yog ntaus nqi rau nws qhov kev txiav txim siab dua li tus mob siab tawv thiab cov leeg ua kom qis dua nrog rau lwm yam xanthines zoo li theophline. Qhov no ua rau nws muaj kev nyab xeeb thiab zoo dua rau cov neeg mob, tshwj xeeb cov kev nkag siab rau kev phiv xws li Tachycardia lossis kev poob siab. Nws ua tau zoo reliymasm, txhim kho cov oxygenation, thiab txo cov tsos mob ntawm ua pa thiab ua pa luv. Nws qhov tseeb ntawm cov tshuaj papacokas profile thiab kuj muaj kev lom zem tsis pub siv rau kev siv hluav taws xob thiab ntev}}}}} kev tswj ntawm kev ua pa nyuaj. Tsis tas li ntawd, nws siv hauv kev tshawb fawb txhawb txoj kev nyab xeeb ntawm kev nyab xeeb thiab siv Xanthine tau zoo dua tshiab}.
