Effectiveness of Topiramate Versus Acetazolamide in the Management of Idiopathic Intracranial Hypertension: ASystematic Review and Meta-Analysis
Abstract
Background and Objectives: Primary pseudotumor cerebri syndrome, another name for idiopathic intracranial hypertension (IIH), is a neurological condition marked by elevated intracranial pressure (ICP) that can result in papilledema without a known etiology. The purpose of this study is to compare the efficacy of topiramate and acetazolamide as medical treatments for IIH and to evaluate the long-term outcomes of both medications. Materials and Methods: This systematic review and meta-analysis followed the PRISMA guidelines and was approved by the International Prospective Register for Systematic Reviews (PROSPERO). This study included randomized clinical trials, retrospective and prospective cohort studies, and patients with idiopathic intracranial hypertension (IIH). Data extraction was performed using the Rayyan application, and the risk of bias was assessed using the Critical Appraisal Skills Program (CASP). Results: The findings revealed a statistically significant 67% increase in the likelihood of improvement at 6 months compared to the baseline with the administration of acetazolamide and topiramate. After six months of the drug administration, there was a 3.6 times decrease in visual obscuration compared to the baseline. A significant advantage of topiramate in IIH is the added benefit of weight loss, since obesity is a modifiable risk factor. However, acetazolamide remains the conventional treatment. Conclusions: This study found that acetazolamide and topiramate are…
