Abstract
To evaluate terahertz time-domain spectroscopy (THz-TDS) as a promising tool for discriminating pharmaceutical tablets, THz-TDS has been applied for discrimination between pharmaceutical tablets with sound-alike names. Two sets of medicine tablets with sound-alike names, that is, Amaryl and Almarl, Zyloric and Zantac, are examined in this study. Based on the difference in THz absorption spectra, we have succeeded in distinguishing between sound-alike medicine tablets clearly for each set. The results in this study suggest that THz-TDS is a useful tool that is indispensable for medical security maintenance, such as a non-destructive way to prevent mix-up of medicine.
