问题 治疗心绞痛急性发作时,为什么要舌下含服硝酸甘油?
选项
答案
解析 硝酸甘油片剂口服首过消除明显,生物利用度仅8%,生效慢。舌下含服时,因其脂溶性高,极易通过口腔黏膜吸收,无首过消除,血药浓度很快达峰值,故起效快,1~2min即可迅速缓解心绞痛症状。

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option).
