1.日常生活中，人们可能会服用各种各样的药物，但是有些药物半衰期很短，容易漏服或错服，长期服用依从性较差，因此药学研发人员绞尽脑汁，通过各种高科技手段将这类药物制成缓控释制剂，以减少每天的服药次数，增加患者的依从性，避免由于漏服或误服导致的不良反应或严重后果。大多数缓控释制剂只需一天服用一次，并且可以控制血药浓度在稳定的范围内，避免血药浓度的波动导致的疗效的改变。缓控释制剂适用于长期服药的慢性病患者。

缓释及控释制剂可以掰开服用吗？

大多数缓释及控释制剂是不可以掰开服用的，因为掰开服用破坏了制剂的工艺结构，导致药物很快释放，不能起缓释或控释的作用，更重要的是由于制剂的含药量大于普通制剂，掰开服用等于把全天的药量一下全吃了，易造成药物中毒，引起不良反应。

但有些特殊注明的缓释及控释制剂是可以掰开服用的，原因是厂家研发的制剂工艺允许掰开或留有刻痕供掰开服用。有的缓控释制剂服用后，其制剂结构(外形)在人体内不被破坏，这些药物会以原形随粪便排出，如果在排泄物中发现整片药，不必感到恐慌。

服用缓释控释制剂注意事项

首先要看说明书。如果说明书中有半片药量的用法，就可以将药片掰开吃。如果说明书中提到“整粒吞服”“不可掰开或碾碎”等，则只能整片服用，以免剂量突释后药效过强或发生严重毒副作用。缓控释制剂的服用间隔除说明书中特殊注明外，一般为12小时或24小时服用1次，应注意不要漏服或随意增加剂量。

其次要看药片。观察药片有无刻痕，一般有刻痕即表示为了能整齐地将药片掰开而设计，则可以沿着刻痕掰开服用，在服用半量时一定要沿刻痕掰开，不要随便掰开。

特殊情况：每天大便3次以上的腹泻患者不适合服用控释片。腹泻期间可换用普通制剂，待腹泻痊愈后再接着服用控释片。
