Rapidly dissolving tablets, also known as orally disintegrating tablets (ODTs) are solid unit dosage forms that disintegrate or dissolve rapidly in the mouth without chewing and water. They offer an advantage particularly for pediatric and geriatric populations who have difficulty in swallowing conventional tablets and capsules. The present study focuses on the formulation and evaluation of Diltiazem HCl rapidly dissolving tablets using both natural and synthetic superdisintegrants, including Sodium Starch Glycolate, Croscarmellose Sodium, Guar Gum, and ground banana flour. Tablets were prepared via dry granulation. The formulations (F1–F8) were developed and subjected to pre-compression (bulk density, tapped density, angle of repose, Hausner’s ratio) and post-compression (hardness, friability, drug content, water absorption ratio, wetting time, dissolution, and disintegration time) evaluations. All parameters met the acceptable limits prescribed by the Indian Pharmacopoeia (IP). Among all formulations, F2 exhibited the shortest disintegration time of 28 seconds and the highest drug release of 98% within 30 minutes. The results demonstrate that natural superdisintegrant like ground banana flour can be effectively used in combination with synthetic agents to formulate efficient ODTs of Diltiazem HCl.
