Antihypertensive drugs are the mainstay of treatment for hypertension. However, the efficacy and safety of these drugs in elderly patients are still uncertain. Therefore, the aim of this systematic review is to evaluate the efficacy and safety of antihypertensive drugs in elderly patients with hypertension.<br ><br >Methods: A comprehensive search of the PubMed, Embase, and Cochrane Library databases was conducted from inception to December 2020. Study selection and data extraction were performed independently by two reviewers. Randomized controlled trials (RCTs) that compared antihypertensive drugs with placebo or other antihypertensive drugs in elderly patients (≥65 years) with hypertension were included. The primary outcome was the mean change in systolic blood pressure (SBP) from baseline to the end of the study. The secondary outcomes were the mean change in diastolic blood pressure (DBP), adverse events, and all-cause mortality.<br ><br >Results: A total of 27 RCTs involving 16,472 elderly patients with hypertension were included in the meta-analysis. The mean age of the patients ranged from 65 to 96 years. The antihypertensive drugs included angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), calcium channel blockers (CCBs), beta-blockers (BBs), and diuretics. The meta-analysis showed that all antihypertensive drugs significantly reduced SBP compared to placebo (mean difference [MD] -15.51 mmHg; 95% confidence interval [CI] -18.11 to -12.91; p<0.00001) and there was no significant difference in efficacy among the different classes of antihypertensive drugs. However, ACEIs and ARBs were associated with a higher incidence of cough and hyperkalemia, and diuretics were associated with a higher incidence of hypokalemia. BBs were associated with a higher incidence of bradycardia and dizziness. The incidence of all-cause mortality was not significantly different between the antihypertensive drug groups and the placebo group.<br ><br >Conclusion: Antihypertensive drugs are effective in reducing SBP in elderly patients with hypertension, regardless of their class. However, different classes of antihypertensive drugs have different safety profiles, and their use should be individualized based on the patient’s comorbidities and risk of adverse effects. Further studies are needed to investigate the optimal antihypertensive drug regimens in elderly patients with hypertension.<br ><br >Keywords: hypertension, elderly, antihypertensive drugs, efficacy, safety, systematic review.<br ><br >以上范文中，文章标题清晰明确，摘要简明扼要地介绍了本文的研究目的、方法、结果和结论。主体部分采用了系统性的文献综述方法，对研究选项、数据提取和数据分析等细节进行了说明。结论部分提出了结论，并强调了研究的不足之处和未来研究的方向。此范文不仅阐述了研究内容，还讲解了常用的文献综述方法和技术语言。降重软件降重靠谱吗<a href=“/” style=“color: blue;”>查论降</a>
