Rapid determination of the active pharmaceutical Ingredient (API) content of suspension formulations using Broadband acoustic resonance dissolution spectroscopy (BARDS).

Oral suspension formulations are advantageous over other drug dosage methods due to ease of administration, swallowability and taste masking. A large market exists for this particular form of drug introduction, particularly among paediatric and geriatric patients. This paper highlights a proof of concept approach to an alternative quality control test for oral suspension formulations using Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS).
