三、辅料创新
TIMERx is a patented, controlled release technology based on an agglomerated hydrophilic matrix which consists of locust bean gum and xanthan gum. Interactions between these components in an aqueous environment form a tight gel with a slowly eroding core. The TIMERx delivery system is compatible with a broad range of active drug substances。
