硝酸甘油口颊片是由硝酸甘油与一种惰性高聚化合物基质组成,片剂放入口腔的上唇与牙龈间后,其表面四周很快就出现一层胶状的外膜,使其粘附在粘膜表面,药物不断从药片中散发而被吸收。口颊片放入口腔后很快发生作用,几乎与舌下含硝酸甘油片相同,高聚化合物的外膜使药片保持完整,从而硝酸甘油可不断向口腔散发。该药溶化时间平均 Nitroglycerin buccal tablets is composed of nitroglycerin and an inert high-polymer matrix composition, the tablet into the oral cavity between the upper lip and gingiva, the surface quickly around a gel-like adventitia, make it adhere On the mucosal surface, the medicine is constantly absorbed from the tablets. Buccal tablets into the oral cavity soon after the role, almost the same with the sublingual nitroglycerin tablets, high polymer compounds of the outer membrane so that tablets remain intact, nitroglycerin can continue to the oral distribution.
