Review of Fast-dissolving Tablets - A New Era in Brand-new Drug Delivery Systems

Fast disintegrating tablets (FDTs) have received ever-increasing demand during the last decade, and the field has become a rapidly growing area in the pharmaceutical industry. Oral drug delivery remains the preferred route for administration of various drugs. Recent developments in the technology have prompted scientists to develop FDTs with improved patient compliance and convenience. Upon introduction into the mouth, these tablets dissolve or disintegrate in the mouth in the absence of additional water for easy administration of active pharmaceutical ingredients. The popularity and usefulness of the formulation resulted in development of several FDT technologies. FDTs are solid unit dosage forms, which disintegrate or dissolve rapidly in the mouth without chewing and water. FDTs, or orally disintegrating tablets, are highly helpful for children and old people who have trouble swallowing standard pills and capsules .This review focuses on lyophilization, moulding, sublimation, and compaction FDT methods, as well as efforts to enhancing FDT qualities, such as spray drying and the usage of disintegrants. Taste-masking technology, experimental disintegration time measurements, and dissolution are also addressed.
