摘要: 目的: 观察索他洛尔(sotalol, S) 治疗心律失常的疗效、副作用与血药浓度的关系。方法: 选择门诊快速房性、室性心律失常患者 100例, 男 53例, 女 47例。依次服用索他洛尔 80、160、240 mg°d-1, 各 2周, 在每个剂量递增期的最后 1 d, 分别于清晨服药前及服药后 3 h(即谷、峰浓度时) 抽外周静脉血3 ml, 反相高效液相色谱-荧光法(HPLC) 测定索他洛尔的血药浓度, 同时检查心电图测量 QT、QTc 间期、QTd 以及动态心电图。结果: 索他洛尔对室早的总有效率为 85.7%, 成对室早和短阵室速总有效率为73.3%、房性心律失常总有效率为 70%, 对预防阵发性房颤发作效果较好(P<0.05), 而对持续性房扑、房颤以控制心室率较理想。索他洛尔治疗有效者平均有效药物浓度谷值为 0.67±0.21 mg°L-1, 峰值 1.33 ±0.51 mg°L-1;无效者平均血药浓度谷值0.69±0.22 mg°L-1, 峰值 1.36 ±0.53 mg°L-1结论: 索他洛尔最佳剂量为 160 ~ 240 mg°d-1, 副作用小, 门诊应用较安全, 持续用药可维持疗效, 对房性及室性心律失常均有效。

Abstract: AIM: To observe the relationship among the effects, side-effects and serum concentration of sotalol in treatment of patients with arrhythmia. METHODS: 100 cases (male 53, female 47) of out patient department (OPD) with atrial or ventricular arrhythmia were select-ed. Every different doses of sotalol (80, 160, 240 mg°d-1) were administrated two weeks in order.Samples of 3 ml peripheral venous blood were collected during the last day of the period of every different dose. The time of blood collecting was in the morning before administration and three hours after administration (i. e.peak and bot-tom serum concentration). RP-HPLC method was adopt-ed. ECG (including QT, QTc episodes and QTd) and Holter examination were performed.RESULTS: Total ef-ficiency of sotalol on arrhythmia :ventricular premature beats (VPB) was 85.7%, couple VPB and paroxysmal ventricular tachycardia was 73.3%, and atrial arrhythmia was 70%.The following resultswere still observed:bet-ter effects on the prevention to paroxysmal atrial fiberal-lation, ventricular rates being better controlled in atrial flutter and fiberallation.The average bottom value (ABV) of the effective serum concentration of the effective cases was 0.67±0. 21 mg°L-1 and the peak value was 1.33± 0.51 mg°L-1, but the ABV of the serum concentration was 0.69 ±0.22 mg°L-1 and peak value was 1.36 ± 0.53 mg°L-1 in ineffective cases.CONCLUSION: The most rational doses of sotalol ranges between 160 -240 mg°d-1 with some advantages, such as lower side ef-fects, and effective to both atrial and ventricular arrhyth-mia.
