Abstract: 
The Fast Dissolving Drug Delivery Systems was an advancement that came into existence in the early 1970’s and combat over the use of the tablets, syrups, capsules which are the other oral drug delivery systems. Fast Dissolving Drug Delivery Systems serves as a major benefit over the conventional dosage forms since the drug gets rapidly disintegrated & dissolves in the saliva without the use of water. Inspite of the downside i.e.., lack of immediate onset of action; these oral dosage forms have beneficial purposes such as self medication, increased compliance, ease of manufacturing and lack of pain. Hence Fast Disintegrating Tablet (FDT) technology has been gaining significance now-a-days with wide variety of drugs serving many purposes. Fast Disintegrating Tablets (FDT) have ever increased their demand in the last decade since they disintegrate in saliva in less than 60 seconds.
