Isosorbide nitrate yog ib qho vasodilator uas nws cov tshuaj tseem ceeb yog los so cov leeg nqaij. Tag nrho cov txiaj ntsig yog txo qis cov pa oxygen ntawm cov leeg nqaij, ua kom cov pa oxygen, thiab txo qis angina pectoris. Kev kho mob tuaj yeem siv los kho ntau hom kab mob plawv angina pectoris thiab tiv thaiv kev tawm tsam. Intravenous drip yuav siv tau rau kev kho mob ntawm congestive plawv tsis ua hauj lwm, ntau yam kev kub siab nyob rau hauv thaum muaj xwm ceev thiab kev tswj ntawm pre-operative hypertension.
25g / nruas, cardboard nruas; Kev kaw cia, qhov cua kub qis thiab lub tsev khaws khoom qhuav, hluav taws kub, cais cia los ntawm oxidizer.
