常見(jiàn)問(wèn)題列表
治療期間,如果患者的靜息心率持續(xù)低于50次/分鐘,或出現(xiàn)與心動(dòng)過(guò)緩有關(guān)的癥狀,應(yīng)將7.5mg或5mg一日兩次的劑量下調(diào)至下一個(gè)較低的劑量。如果患者的靜息心率持續(xù)高于60次/分鐘,應(yīng)將2.5mg或5mg一日兩次的劑量上調(diào)至上一個(gè)較高的劑量。
腎功能不全且肌酐清除率大于15ml/min的患者無(wú)需調(diào)整劑量,尚無(wú)肌酐清除率 低于15ml/min的患者使用本品的臨床資料,此類人群用藥時(shí)需謹(jǐn)慎。
輕度肝損害患者無(wú)需調(diào)整劑量,中度肝損害患者使用本品時(shí)需謹(jǐn)慎,重度肝功能不全患者禁用本品。
最常見(jiàn)的不良反應(yīng)為閃光現(xiàn)象(光幻視)和心動(dòng)過(guò)緩,為劑量依賴性,與伊伐布雷定的藥理學(xué)作用有關(guān)。
較為常見(jiàn)的不良反應(yīng)還包括:神經(jīng)系統(tǒng)疾病,如頭暈、頭痛;視力模糊;心臟疾病,如心動(dòng)過(guò)緩、Ⅰ度房室傳導(dǎo)阻滯、室性期外收縮、心房顫動(dòng);血壓控制不佳。
不常見(jiàn)或罕見(jiàn)的不良反應(yīng)包括:嗜酸性粒細(xì)胞增多癥,高尿酸血癥,暈厥,復(fù)視,視覺(jué)障礙,心悸、室上性期外收縮,低血壓,呼吸困難、惡心、嘔吐、腹瀉,血管性水腫、皮疹,肌肉痙攣,血肌酐升高等。
哺乳期婦女:動(dòng)物研究顯示伊伐布雷定可分泌至乳汁,因此,哺乳期婦女禁用。
兒童:尚無(wú)18歲以下兒童使用本品的數(shù)據(jù)。
老人:75歲或以上的老年患者,應(yīng)考慮以較低的起始劑量開(kāi)始給藥(2.5mg),必要時(shí)調(diào)整劑量。

Ivabradine hydrochloride treatment (10 mg/kg/d) induces long-term HRR, and that improves diastolic LV function probably involving attenuated hypoxia, reduced remodeling, and/or preserved nitric oxide bioavailability, resulting from processes triggered early after HRR initiation: angiogenesis and/or preservation of endothelial nitric oxide synthase expression. Ivabradine hydrochloride leads to a sustained 15-20% heart rate reduction, but has no effect on blood pressure. While ivabradine has no effect on endothelial function and vascular reactive oxygen species production in angiotensin II-treated rats, it improves both parameters in ApoE knockout mice. Ivabradine hydrochloride treatment leads to an attenuation of angiotensin II signaling and increased the expression of telomere-stabilizing proteins in ApoE knockout mice, which may explain its beneficial effects on the vasculature. The absence of these protective ivabradine effects in angiotensin II-infused rats may relate to the treatment duration or the presence of arterial hypertension.
