To compare the safety and tolerability of two formulations of brimonidine ophthalmic solution, brimonidine Purite (P) 0.1% and brimonidine P 0.15%, for reducing intraocular pressure in patients with glaucoma or ocular hypertension (OHT).
Meta-analysis of safety and tolerability results from two previously reported prospective, randomized, 12-month, double-masked, multicenter, parallel-group clinical studies with similar entry criteria and protocols. In study 1 (two clinical trials), after washout of previous medications, patients with glaucoma or OHT were randomized to thrice-daily treatment with brimonidine P 0.15% (n = 381), brimonidine P 0.2% (n = 383), or brimonidine 0.2% (n = 383). In study 2 (one clinical trial), the treatment arms were thrice-daily brimonidine P 0.1% (n = 215) and brimonidine 0.2% (n = 218).
Treatment-related adverse events (AEs) and discontinuations due to AEs.
Treatment-related AEs were significantly reduced with brimonidine P 0.15% compared with brimonidine 0.2% in study 1 (p < 0.001). Treatment-related AEs and discontinuations due to AEs were significantly reduced with brimonidine P 0.1% compared with brimonidine 0.2% in study 2 (p < or = 0.014). In the meta-analysis of study 1 and study 2, the overall incidence of treatment-related AEs was lower with brimonidine P 0.1% than with brimonidine P 0.15% (41.4 vs. 49.7%; p = 0.050). Although the incidence of treatment-related ocular AEs was similar with brimonidine P 0.1% and 0.15% (p = 0.461), treatment-related systemic AEs were less frequent with brimonidine P 0.1% than with brimonidine P 0.15% (4.7 vs. 14.2%; p < 0.001), and there were fewer discontinuations due to systemic AEs with brimonidine P 0.1% than with brimonidine P 0.15% (p = 0.025).
Brimonidine P 0.1% has improved systemic safety and tolerability compared with brimonidine P 0.15%. The ocular safety and tolerability of the formulations are similar. The present meta-analysis is based on only two clinical studies, and additional studies further evaluating the safety and tolerability of these medications are warranted.
比较两种布林佐胺滴眼液制剂(0.1%普瑞明(P)布林佐胺和0.15% P布林佐胺)在降低青光眼或高眼压症(OHT)患者眼压方面的安全性和耐受性。
对两项先前报道的前瞻性、随机、为期12个月、双盲、多中心、平行组临床研究的安全性和耐受性结果进行荟萃分析,这两项研究具有相似的纳入标准和方案。在研究1(两项临床试验)中,在停用先前药物后,青光眼或OHT患者被随机分为每日三次接受0.15% P布林佐胺治疗(n = 381)、0.2% P布林佐胺治疗(n = 383)或0.2%布林佐胺治疗(n = 383)。在研究2(一项临床试验)中,治疗组为每日三次接受0.1% P布林佐胺治疗(n = 215)和0.2%布林佐胺治疗(n = 218)。
治疗相关不良事件(AE)以及因AE导致的停药情况。
在研究1中,与0.2%布林佐胺相比,0.15% P布林佐胺显著减少了治疗相关AE(p < 0.001)。在研究2中,与0.2%布林佐胺相比,0.1% P布林佐胺显著减少了治疗相关AE以及因AE导致的停药情况(p ≤ 0.014)。在对研究1和研究2的荟萃分析中,0.1% P布林佐胺治疗相关AE的总体发生率低于0.15% P布林佐胺(41.4%对49.7%;p = 0.050)。尽管0.1%和0.15% P布林佐胺治疗相关眼部AE的发生率相似(p = 0.461),但0.1% P布林佐胺治疗相关全身AE的发生率低于0.15% P布林佐胺(4.7%对14.2%;p < 0.001),并且因全身AE导致停药的情况,0.1% P布林佐胺比0.15% P布林佐胺更少(p = 0.025)。
与0.15% P布林佐胺相比,0.1% P布林佐胺改善了全身安全性和耐受性。两种制剂的眼部安全性和耐受性相似。本荟萃分析仅基于两项临床研究,因此有必要进行更多研究以进一步评估这些药物的安全性和耐受性。
