| 一般建议 | 为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异，仅做参考。若实验所需浓度过大至产品溶解极限，请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存，请尽快用完。 |
Labetalol HCl is a selective antagonist for the α1-adrenergic receptor and a non-selective antagonist for the β-adrenergic receptor. Labetalol HCl has been used for the treatment of high blood pressure. Labetalol HCl competitively targets the α1-adrenergic receptors expressed in vascular smooth muscle, thus inhibiting adrenergic stimulation on endothelial cells and vasoconstriction in peripheral blood vessels. Labetalol HCl also blocks the β-adrenergic receptors in bronchial and vascular smooth muscle to counteract adrenergic stimulation. Ultimately, labetalol HCl causes decreases in resting and exercise heart rates, cardiac output, as well as in both systolic and diastolic blood pressure, exherting vasodilation, as well as negative chronotropic and inotropic cardiac effects.

| Animal experiment:[2] | |
Animal models | Anaesthetized dogs |
Dosage form | 0.03 ~ 1 mg/kg Given intravenously and into the vertebral artery |
Applications | Labetalol HCl did not cause any immediate (5 min) change in blood pressure or heart rate when given by either route. When the cumulative dose of labetalol HCl reached 2.86 mg/kg, blood pressure fell significantly. In addition, intravenous administration of 0.03 mg/kg labetalol HCl was enough to increase heart rate at its first dose. |
