Abstract: Oral drug delivery has been recognized as the most desirable drug administration method among other drug delivery routes due to its ease of administration, long shelf life, and low cost. Orally disintegrating tablets disintegrate within seconds in the mouth without the need of water for swallowing. This unique feature of orally disintegrating tablets is favorable to special populations such as geriatric and pediatric patients. Formulation optimization is significant to obtain the optimal combination of tablet constituents, as the tablet composition is influential on dosage-form characteristics. The objective of this study was to investigate the effect of different types of fillers and percentage on the physical properties of orally disintegrating tablets by using amlodipine as the model drug. Blank orally disintegrating tablets containing different fillers, namely, Sorbolac 400, Granulac 200, and CombiLac with different percentages, were prepared using the wet granulation method and were evaluated based on weight variation, hardness, thickness, friability, and disintegration time. Formulation 5 that consists of 25% Granulac 200 showed the optimal result among all formulations with the fastest disintegration time (96.17 s Å} 18.40) and sufficient tablet hardness (4.59 kg Å} 0.70). Hence, formulation 5 was selected as the optimal formulation and incorporated with amlodipine. From this study, it can be concluded that excipients have an essential role in determining the physical properties of orally disintegrating tablets.
