Orally disintegrating tablets (ODTs) are solid dosage forms containing medicinal substances which disintegrate rapidly, usually in a matter of seconds, when placed on the tongue. Super-disintegrants plays the major role in oro-dispersible tablet. Bambuterol Hcl oral disintegrating tablet was prepared by direct compression method with fifteen various formulations (F1 to F15).then the tablets were evaluated for pre- compression studies include bulk density, tapped density, Carr’s index (or) % compressibility, Hausner ratio and Angle of repose. Evaluation studies include hardness, thickness, friability test, weight variation test wetting time, water absorption ratio, drug content estimation, disintegration test, In-vitro dissolution study and stability Studies. The formulation (F5) containing 4% crospovidone gave the least disintegration time of about 10 sec among all formulations. It also released a maximum of 101% of drug within 30mins and hence the formulation (F5) was selected as the best formulation.
