Does alprazolam ODT work faster than alprazolam?

Orally disintegrating tablets (ODT) or fast-melting tablets have gained appeal lately. ODT are tablets which disintegrate in the mouth within seconds without the need for additional liquid. This dosage form was originally developed to improve the compliance of patients who had difficulty in swallowing tablets, such as children, the elderly and bedridden patients. ODTs combine the advantages of solid dosage forms with those of liquid forms and appeal to broader groups of patients than originally expected. ODTs may prove to have higher bioavailability and an earlier pharmacological effect than conventional tablets. Technical challenges are related to taste masking, mechanical strength and stability to humidity.
