Disintegrants are substances which promote disintegration of the solid dosage form in the dissolution medium or body fluids. Efficient disintegration is an important prerequisite for ensuring release of the active substance and its good bioavailability. Several mechanisms of disintegrants´ action are currently recognized, but disintegration is a complex process, and the majority of substances act by combining multiple mechanisms. Superdisintegrants as an innovative materials allow more efficient disintegration of the dosage form in lower concentrations, without any negative impact on processability and mechanical properties of the final dosage form. Currently are in pharmaceutical technology used synthetic, modified (semi-synthetic), and also natural superdisintegrants, whose main representatives discribes this article. Key words: disintegrants • superdisintegrants • solid dosage forms • tablets • disintegration time • excipients.
