Oral Disintegrating Tablets - An Updated Patent Perspective.

Current Development in drug delivery system has been employed with an endeavour to enhance the bioavailability of the drug, mask its taste, induce the rapid onset of action and improve patient compliance. An alternative approach to the conventional dosage form is being employed to triumph over all these issues named as Orodispersible system. Over the past three decades, this novel dosage form has gained considerable attention as compared to other conventional solid dosage forms such as tablets and capsules. ODTs dissolve or disintegrate within a few seconds or a minute when put on the tongue, without the need for water. ODT has an advantageous effect on paediatrics and geriatrics patients with dysphagia. Over the last decade, widespread advances in the formulation of ODTs have been executed in academia and industry that resulted in the emergence of a large number of patents. Products developed from ODT mechanics launched in the market in the 1980s have grown bit by bit in demand and their products are rapidly escalating. Expanding in the technology forum based on industrialization, these systems include the use of lyophilization, cotton candy, sublimation, melt extrusion and direct compression in addition to the conventional wet granulation processes and patent techniques. The present study focused on non-patent and patent citations concerning ODT along with active ingredients, techniques used and results of the innovations.
