直立性低血压是由于植物神经系统功能失调,在直立位时血压下降而导致脑血流量不足的情况,患者主要症状为直立时出现头重脚轻,眩晕、晕厥、视力模糊、全身无力、发音含糊和共济失调,也有的患者,在行走后,由于下肢血管扩张而发生直立性低血压。研究表明,前列腺素具有扩张血管的作用,某些直立性低血压患者可能与体内前列腺素量多有关,消炎痛具有抑制前列腺素合成的作用。所以服用消炎痛不仅使直立性低血压患者的收缩压与舒张压升高,也能使其他症状得到改善。
Orthostatic hypotension is due to autonomic dysfunction, decreased blood pressure in the upright position leading to cerebral blood flow deficiencies, the main symptoms of patients with erectile dysfunction, dizziness, fainting, blurred vision, generalized weakness, vague vocal and total Economic disorders, and some patients, after walking, due to lower extremity vascular dilatation and orthostatic hypotension. Studies have shown that prostaglandins have the role of dilation of blood vessels, some patients with orthostatic hypotension may be related to the body and more prostaglandin, indomethacin inhibition of prostaglandin synthesis. Therefore, taking indomethacin not only to systolic and diastolic blood pressure in patients with orthostatic hypotension, but also make other symptoms can be improved.
