Sustained release technologies is characterised because of the gradual releasing of a here specific substance at a programmed amount to provide the drug to get a prolonged time frame.
Prolonged-release tablets are just like sustained-release tablets, but These are meant to release the drug extra slowly over a far more extended period of time. This ends in a far more gradual increase in the drug focus from the bloodstream, with the utmost concentration being reduce than that obtained by instant-release or sustained-release tablets.
