Starch is a commonly used excipient in the pharmaceutical industry. However, information on the effect of the moisture scavenging properties of starch to protect moisture-sensitive drugs is limited. The interaction between starch and moisture is of particular interest as moisture fugacity can impact drug stability. In this study, the moisture behavior of different starches was examined for an understanding of its role in the degradation of acetylsalicylic acid. The starches were characterized for their dimensional- and moisture-related properties. Stability testing was carried out on tablets containing acetylsalicylic acid and different starches. Although moisture sorption processes were visually comparable for the different starches, quantitative differences were found in their moisture interaction and distribution. From the sorption isotherms, moisture monolayer coverage and area of hysteresis were found to correlate well with the percentage of acetylsalicylic acid degradation. The lowest percentage of acetylsalicylic acid degradation was observed in starch that exhibited high monolayer coverage, large area of hysteresis, and good capacity for internally absorbed moisture. Findings from this study highlighted the value of moisture scavenging excipients when formulating moisture-sensitive drug products. Clearly, the assessment of moisture sorption properties of excipients during the preformulation phase can be an invaluable exercise for identifying the best possible ingredients in formulations where moisture sensitivity is an area of concern.

深入了解含湿敏药物片剂中不同类型淀粉的水分清除特性

淀粉是制药工业中常用的赋形剂。然而,关于淀粉的水分清除特性对保护水分敏感药物的影响的信息是有限的。淀粉和水分之间的相互作用特别令人感兴趣,因为水分逸度会影响药物稳定性。在这项研究中,研究了不同淀粉的水分行为,以了解其在乙酰水杨酸降解中的作用。淀粉的特征在于它们的尺寸和水分相关特性。对含有乙酰水杨酸和不同淀粉的片剂进行了稳定性测试。尽管不同淀粉的吸湿过程在视觉上具有可比性,但在它们的水分相互作用和分布上发现了数量上的差异。从吸附等温线,发现水分单层覆盖率和滞后面积与乙酰水杨酸降解的百分比密切相关。在表现出高单层覆盖率、大面积滞后和良好内部吸收水分能力的淀粉中观察到最低百分比的乙酰水杨酸降解。这项研究的结果突出了水分清除赋形剂在配制水分敏感药物产品时的价值。显然,在配方前阶段评估赋形剂的吸湿性能对于确定配方中可能存在的最佳成分是一项非常宝贵的工作,其中水分敏感性是一个关注领域。在表现出高单层覆盖率、大面积滞后和良好内部吸收水分能力的淀粉中观察到最低百分比的乙酰水杨酸降解。这项研究的结果突出了水分清除赋形剂在配制水分敏感药物产品时的价值。显然,在配方前阶段评估赋形剂的吸湿性能对于确定配方中可能存在的最佳成分是一项非常宝贵的工作,其中水分敏感性是一个关注领域。在表现出高单层覆盖率、大面积滞后和良好内部吸收水分能力的淀粉中观察到最低百分比的乙酰水杨酸降解。这项研究的结果突出了水分清除赋形剂在配制水分敏感药物产品时的价值。显然,在配方前阶段评估赋形剂的吸湿性能对于确定配方中可能存在的最佳成分是一项非常宝贵的工作,其中水分敏感性是一个关注领域。这项研究的结果突出了水分清除赋形剂在配制水分敏感药物产品时的价值。显然,在配方前阶段评估赋形剂的吸湿性能对于确定配方中可能存在的最佳成分是一项非常宝贵的工作,其中水分敏感性是一个关注领域。这项研究的结果突出了水分清除赋形剂在配制水分敏感药物产品时的价值。显然,在配方前阶段评估赋形剂的吸湿性能对于确定配方中可能存在的最佳成分是一项非常宝贵的工作,其中水分敏感性是一个关注领域。
