Background:
Calcium alginate is a biopolymer that can be used for developing oral drug-delivery systems[1]. Calcium alginate is a pH sensitive hydrogel stable in acidic media and soluble in basic media[2].
Calcium alginate is a pH sensitive hydrogel stable in acidic media and soluble in basic media. This enables the hydrogel to absorb and release aqueous solutions at certain ranges of pH values. By absorbing an aqueous solution containing a drug, an active drug release can be triggered at a specified range of pH value[2]. Calcium alginate is a biodegradable gel-transforming agent widely used for nasal packing. It can reduce pain and improve comfort[3].
