The photoacoustic spectra of the powder mixture of methaphyllin with lactose and of acrinol and zinc oxide ointment were measured in the visible region. Linear relationships between relative photoacoustic signal and the concentration of drug were observed in the two systems. Each correlation coefficient of the regression line was more than 0.99. It is considered that photoacoustic spectroscopy is a useful method for the quantitative analysis of drug in the powder mixture and of drug in the ointment.
