非诺洛芬钙缓释片的研制及释药性质研究

Studies on Preparation and Release Properties on Slow Released Fenoprofen Calcium Tablets

  • 摘要: 为减少非诺洛芬钙(fenoprofencalcium)的胃肠道刺激性和副作用,根据水凝胶骨架释放机理,研制了非诺洛芬钙缓释片。通过测定制剂的体外溶出度评价了该缓释片的处方。结果表明该制剂的体外溶出行为符合Higuchi方程,释药常数(K)主要受原辅料比例的影响。不同处方的释药常数,50%释药时间(T50)和63.2%释药时间(Td)有显著差异(P<0.01)。处方5具有良好的缓释效果,其T50和Td分别为288min和438min。此外,溶出介质pH、转速及溶出试验方法对该制剂的释药速度常数也有影响。
