To evaluate in vitro quality of enteric-coated 50 mg diclofenac sodium tablet formulations on Saudi market.
A reference and seven generic (G1-7) formulations were commercially available in December 2019/January 2020 and were assessed within 25-75% of manufacture-expiration period. Weight variation (range as% difference from mean, n = 20), active substance content (ASC, mean (SD) as% difference from label, n = 20), hardness (mean (SD), n = 10), and friability (% weight loss, n = 20) were 97-103%, 102.0% (3.4%), 15.4 (1.1) kg, and 0.24%, respectively, for the reference. For G2-7, they were ≤ ±5%, 98.6% (4.0%) to 109.9% (1.8%), 11.9 (0.9) to 18.3 (0.8) kg, and ≤ 0.00 to 0.75%, respectively. G1 ASC, hardness, and friability were 111.3% (1.7%), 20.1 (1.7) kg, and 1.10%, respectively. Disintegration time (n = 6) and dissolution profile (n = 8) were also determined. No formulation disintegrated or released ˃ 0.1% of label ASC in 0.1 N HCl for 2 h. The reference disintegrated in 15:00 min:seconds and released a mean (range) of 100% (99-103%) of label ASC by 45 min in phosphate buffer (pH = 6.8). G1-7 disintegrated in 8:53 to 20:37 min:seconds and released 81% (69-90%) (G1) to 109%. Except for borderline performance of G1, all formulations passed in vitro quality tests according to United States Pharmacopoeia.
评估沙特市场上50毫克双氯芬酸钠肠溶片制剂的体外质量。
2019年12月/2020年1月有1种参比制剂和7种仿制药(G1 - 7)在售,且在生产日期至有效期的25% - 75%范围内进行了评估。参比制剂的重量差异(范围为与均值的百分比差异,n = 20)、活性物质含量(ASC,均值(标准差)为与标签的百分比差异,n = 20)、硬度(均值(标准差),n = 10)和脆碎度(重量损失百分比,n = 20)分别为97% - 103%、102.0%(3.4%)、15.4(1.1)千克和0.24%。对于G2 - 7,它们分别为≤±5%、98.6%(4.0%)至109.9%(1.8%)、11.9(0.9)至18.3(0.8)千克和≤0.00%至0.75%。G1的ASC、硬度和脆碎度分别为111.3%(1.7%)、20.1(1.7)千克和1.10%。还测定了崩解时间(n = 6)和溶出曲线(n = 8)。在0.1 N盐酸中2小时内,没有制剂崩解或释放超过标签ASC的0.1%。参比制剂在15分00秒崩解,并在45分钟内在磷酸盐缓冲液(pH = 6.8)中释放了标签ASC的均值(范围)为100%(99% - 103%)。G1 - 7在8分53秒至20分37秒崩解,并释放了81%(69% - 90%)(G1)至109%。除G1的性能接近临界外,所有制剂均根据美国药典通过了体外质量测试。
