Dose-response relationship of the β-adrenoceptor antagonist bisoprolol in patients with coronary heart disease and chronic obstructive bronchitis

Summary The effects of single, consecutively increased, oral doses of the -adrenoceptor antagonist bisoprolol (5, 10, 15, 20, 30 and 40 mg) on blood pressure, heart rate and bronchomotor tone were investigated in an open acute trial with 16 patients suffering from angina pectoris due to coronary heart disease and reversible chronic obstructive bronchitis. Even the lowest dose of bisoprolol (5 mg) caused a marked, long-lasting reduction in blood pressure and heart rate. After doses exceeding 20 mg, the incidence of an exaggerated pharmacodynamic effect on heart rate ( ₁-blockade) increased with dose. At doses above 30 mg, bisoprolol showed incipient impairment of bronchomotor function ( ₂-blockade) in individual patients. It is concluded that bisoprolol exhibits high ₁-selectivity, i.e. a wide ₁/ ₂ split, since blockade of bronchial ₂-receptors only occurred at doses well above the therapeutically relevant dose range. The results may not be applicable to chronic treatment.

报道反相高效液相色谱法测定富马酸比索洛尔片的含量。方法采用ＹＷＧ－Ｃ１８柱,以对羟基苯甲酸丙酯为内标物,甲醇－０．１ｍｏｌ．Ｌ＾－１醋酸钠缓冲注为流动相,检测波长２７０ｎｍ。结论方法简便,准确,专属。     

Effects of bisoprolol on blood pressure,serum lipids and HDL-cholesterol in essential hypertension

Summary Fifty patients with essential hypertension WHO Grades I–II have been treated for 3 months with bisoprolol, a new selective betablocker, in doses up to 40 mg once daily. Forty-three patients reached the preset target diastolic blood pressure of 90 mmHg on a mean daily dose of 16.8 mg bisoprolol. There was no effect on serum lipids and HDL-cholesterol during the study. The side-effects were mild and were those usually associated with beta-blocking therapy.     

比索洛尔治疗充血性心力衰竭临床观察

目的:观察比索洛尔治疗充血性心力衰竭疗效。方法:54例充血性心力衰竭患者,在常规治疗病情基本稳定的基础上,随机分为对照组25例和治疗组29例。对照组给予地高辛、利尿剂、血管紧张素转换酶抑制剂(ACEI)或血管紧张素受体拮抗剂(ARB)治疗;治疗组在常规治疗的基础上,给予比索洛尔治疗,比索洛尔从1.25 mg Qd开始,缓慢递增,至10 mg Qd或最大耐受剂量,随访时间为12周。治疗前后分别进行心功能(NYHA)分级、血压、心率测定、超声心动图检查并做统计学处理。结果:与治疗前相比:对照组心功能分级改善(P<0.05),左室射血分数(LVEF)增加(P<0.05);治疗组心功能分级显著改善(P<0.01),LVEF和左室短轴缩短率(FS)明显增加(P<0.01),左室舒张末期内径(LVDd)显著缩短(P<0.01),左室收缩末期内径(LVDs)缩短(P<0.05)。两组治疗后相比,比索洛尔组LVEF、FS较常规组改善更为显著(P<0.01)。结论:比索洛尔在心衰常规治疗基础上治疗充血性心力衰竭有良好的疗效,能显著改善心功能,改善衰竭左室的重构。     

Supraventricular tachyarrhythmias that responded dramatically to bisoprolol transdermal patches in two patients undergoing hemodialysis

We here report two patients with atrial flutter (AFL) and paroxysmal supraventricular tachycardia (PSVT) who were undergoing hemodialysis and returned quickly to normal sinus rhythm without hypotension when treated with bisoprolol transdermal patches (Bisono^® Tape) (TOA EIYO, Tokyo, Japan). Spontaneous rhythm reversion had not occurred prior to these events in either patient. Our findings indicate that Bisono^® Tape may be a new and more effective treatment for AFL and PSVT in patients undergoing hemodialysis.     

氨氯地平对比索洛尔在大鼠体内药动学的影响

目的探讨氨氯地平对比索洛尔在大鼠体内药动学的影响。方法 12只大鼠随机分为两组,一组给予比索洛尔灌胃,另一组给予比索洛尔与氨氯地平灌胃,分别采用液相色谱-串联质谱法测定两组大鼠血浆中比索洛尔的血药浓度。用DAS2.0程序软件拟合药动学参数,比较两者的药动学参数。结果单独给药组和联合给药组的主要药动学参数:Cmax分别为(513.36±56.02)和(585.21±77.52)ng/ml,t1/2:(1.30±0.51)和(1.51±0.65)h,AUC0-t:(433.70±50.98)和(721.16±218.09)ng/(h.ml),CL/F:(38.02±5.63)和(25.9±5.18)L/(h.kg),两组间AUC0-t和CL/F的差异具有统计学意义(P<0.05)。结论建立的液相色谱-串联质谱法专属性、准确性、灵敏度适宜。氨氯地平可延长比索洛尔在大鼠体内的吸收和排泄,对比索洛尔的药代动力学有显著影响。     

比索洛尔对不稳定型心绞痛患者心率震荡的影响

目的观察不稳定型心绞痛（UAP）患者窦性心率震荡（HRT）的变化及比索洛尔对HRT的影响。方法选择有室性早搏的UAP患者60例,及健康对照60例进行24h动态心电图（DCG）检查,分别对震荡初始（TO）、震荡斜率（TS）进行分析,UAP组患者每日服用比索洛尔4周后复查DCG及TO、TS。结果UAP组与对照组比较,TO明显升高,TS明显降低;UAP患者恶性室性心律失常组与非恶性室性心律失常组对比．TO升高、偈下降;UAP患者服用比索洛尔前后对比,TO降低、TS增加,HRT明显改善。结论UAP组HRT明显异常,HRT异常可作为预测UAP恶性室性心律失常发生及判断预后的重要指标,比索洛尔能减少室性心律失常的发生率,改善HRT。
