Effervescent tablet principle

Effervescent tablets use effervescent disintegrants produced by the reaction of basic carbonic acid and citric acid.

It is this phenomenon that gives the name effervescent tablets.

Brief introduction of effervescent tablets

Effervescent tablet is a relatively new pharmaceutical dosage form in China, which consists of main drug, diluent, adhesive, disintegrant, lubricant and other auxiliary materials. The diluent, adhesive, lubricant and other auxiliary materials used are the same as ordinary tablets, while the disintegrant is mainly acid source and alkali source. The commonly used acid sources are citric acid, malic acid, boric acid, tartaric acid, fumaric acid, inorganic acid (hydrochloric acid) and so on.
