The Science Behind Optizorb Technology

Optizorb technology contains three main ingredients which are: alginic acid that draws fluid from the stomach into the tablet causing it to swell and break apart; calcium carbonate that works together with alginic acid to boost the disintegration of the tablet and, crospovidone which acts as a superdisintegrant due to its ability to dissolve well in water.1,2

Paracetamol disintegrating in the stomach

Basics of Optizorb technology

This is a revolutionary technology that helps speed the breakdown of paracetamol tablets in the stomach2 so that the drug is absorbed fast and pain relief can start as early as 15 minutes after paracetamol ingestion with 2 tablets (1000 mg dose).3

The absorption of paracetamol occurs in the small intestine and as such is dependent on the rate of emptying of stomach contents into the small intestine. Optizorb technology increases the gastric emptying time of the drug.2
