In vitro, ex vivo and in vivo evaluation of taste masked low dose acetylsalicylic acid loaded composite wafers as platforms for buccal administration in geriatric patients with dysphagia

This study reports the development and characterization of taste masked, freeze-dried composite wafers for potential oral and buccal delivery of low dose aspirin (acetylsalicylic acid) to prevent thrombosis in elderly patients with dysphagia. The wafers were formulated by combining metolose (MET) with carrageenan (CAR), MET with chitosan (CS) at low molecular weight or CAR with CS using 45% v/v ethanol as solvent for complete solubilization of...
