物化性质 | 人工合成的加压素类物质,即将加压素的2位酪氨酸换成苯丙氨酸,8号位的精氨酸换成赖氨酸。具有选择性升压作用和止血作用。在升压和止血剂量范围内不产生子宫收缩、催乳及抗利尿等作用。冠状血管收缩作用较轻微,其血管收缩作用约为赖氨酸加压素的5倍,而抗利尿作用极小,仅为加压素的1/10-1/40。升压作用缓和,维持作用时间较长。宜与卤烷麻醉剂配伍。与肾上腺素合用,不致引起心室颤动等心律失常。 |
体外研究 | Felypressin is a synthetic hormone of the posterior pituitary lobe characterized by vasoconstrictor properties that is widely used in dental procedures. The vasoconstrictor action of Felypressin seems to be mediated by V1 receptors of the blood vessel smooth muscle cells. |
体内研究 | Felypressin can reduce toxicity during dental procedures. Felypressin increases the diastolic blood pressure of hypertensive patients with controlled blood pressure. Cardiovascular effects of Felypressin (240 ng/kg; intravenous injection) are studied in Wistar rats. Felypressin induces a pressor effect. Felypressin depends on V1 receptors to induce pressor and bradycardic effects, and that it produces a high relationship between bradycardia and mean arterial pressure variation depending on area postrema and central V1 receptors. |
