Isosorbide nitrate yog vasodilator uas nws lub chaw muag tshuaj tseem ceeb yog los so vascular du cov leeg. Cov nyhuv tag nrho yog kom txo cov pa oxygen ntawm lub plawv nqaij, nce cov zaub oxygen, thiab daws cov pa roj oxygen Cov chaw kho mob tuaj yeem siv los kho ntau ntau yam kev mob plawv plawv angaka pectoris thiab tiv thaiv kev tawm tsam. Lub plawv tau siv tau rau kev kho mob lub plawv tsis ua haujlwm, ntau hom kev kub siab thaum muaj xwm ceev thiab rau kev tswj hwm ntawm kev kub ntxhov.
25G / Nruas, Duab los ntawm lub nruas; Kaw cia, kom kub kub sov thiab cov khoom siv hluav taws qhuav, tua hluav taws, cais cia ntawm oxidizer.
