Combined therapy of hypertensive nephropathy with ginkgo leaf extract and dipyridamole injection and antihypertensive drugs

Abstract

Background: In recent years, the incidence rate of hypertensive nephropathy has been increasing quickly, which has been a major threat to people's health. Renin-angiotensin-aldosterone system blockers have certain curative effects. However, there are some patients having serious adverse reactions, and the benefit population is limited, so the treatment of hypertensive renal damage is necessary to have beneficial supplement. More and more clinical studies have shown that ginkgo leaf extract and dipyridamole injection (GDI) combined with antihypertensive drugs has achieved good results in the treatment of hypertensive renal damage. It is supposed to be a supplementary treatment in hypertensive nephropathy. Objectives: To systematically assess the efficacy and safety of GDI combined with antihypertensive drugs on hypertensive renal injury. Methods: Seven databases including PubMed, Cochrane Library, Embase, Wanfang database, China biomedical literature service system (Sino Med), VIP Chinese Sci-tech journal database (VIP), and China national knowledge internet (CNKI) were retrieved to collect randomized controlled trials (RCTs) in the experimental group containing combined therapy of hypertensive nephropathy with GDI and antihypertensive drugs. The retrieval time was from the establishment of database to July 8, 2020. Two researchers independently selected literature, extracted data, and evaluated the risk of bias in the study. The methodological quality was evaluated with Cochrane handbook and meta-analysis was performed with Stata 14.0 software. Results: Eight studies were included in this study which involved 556 patients. The meta-analyses indicated that, compared with using antihypertensive drugs alone, combined treatment of GDI with antihypertensive drugs can decrease 24-hour urinary total protein (weighted mean difference [WMD] –0.61, 95% confidence interval [CI]: –0.82, –0.39; k = 6, P ≤ .001), blood urea nitrogen (WMD –1.27, 95% CI: –2.45, –0.10; k = 6, P = .033, serum creatinine (WMD –29.50, 95% CI: –56.44, –2.56; number of estimates [ k ] = 6, P = .032). Conclusions: Our meta-analyses showed that GDI combined with antihypertensive drugs can improve the renal function of hypertensive patients with renal injury.

Treatment of Hypertension by Using Natural Herbs and their Mechanism of Action

“…In the dementia diagnosis, including vascular, mixed dementia, and Alzheimer's, fruits and leaves from the ginkgo tree. Ginkgo leaf is also utilized for cerebral vascular insufficiency disorders, particularly for the elderly, including headaches, memory loss, dizziness, tinnitus, hearing disorders, and trouble mood (Jialiken et al, 2021). There is also orally consumed for ischemic stroke.…”

“…[ 93 ] A meta‐analysis study illustrated that combination of EGb with antihypertensive drugs might improve blood pressure and renal function in patients with hypertensive nephropathy. [ 94 ] Significantly, EGb protects endothelial cells by inhibiting thromboxane A2 activity and promoting the production and release of prostacyclin I2 and nitric oxide (NO). Likewise, EGb inhibited endothelin 1 (ET‐1) release, thereby controlling tissue blood flow and vascular tension in patients with coronary artery disease.…”
