產(chǎn)品簡(jiǎn)介:
Flecainide acetate是非選擇性Na (+)通道阻滯劑,是1C類(lèi)抗心律失常藥,尤其用于治療室上性心律失常。Flecainide acetate已被廣泛用于提供長(zhǎng)期竇性心律(SR)恢復(fù)以及減少房顫癥狀。 Flecainide acetate抑制心臟Nav1.5鈉通道,導(dǎo)致心臟動(dòng)作電位延長(zhǎng)。Flecainide acetate可降低完整大鼠心肌細(xì)胞的鈣火花、鈣波頻率和鈣波速度。此外,氟卡胺還顯示出在I(Na)活躍時(shí)減少Ca(2+)波。已經(jīng)證明氟卡胺可以顯著增加Na(+)/Ca(2+)-交換劑(NCX)介導(dǎo)的Ca(2+)外排[1]。
據(jù)報(bào)道,氟卡胺可延長(zhǎng)心室復(fù)極,對(duì)左心室心外膜的作用強(qiáng)于右心室心外膜。發(fā)現(xiàn)氟卡胺在心內(nèi)膜比心外膜產(chǎn)生更大的有效不應(yīng)期(ERP)延長(zhǎng),導(dǎo)致跨室壁的ERP離散度顯著增加[2]。 氟卡胺已顯示出劑量依賴性地降低全身壓力(0.8 μg/mL時(shí)為32%)和外周血管阻力(0.8 μg/mL時(shí)為15%)。此外,在大鼠后肢灌注模型中,在治療血漿濃度下,0.8 μg/mL的氟卡胺顯著降低心率(55次/分鐘)并增加QRS間期(9.9毫秒)[3]。
