Identification of Sildenafil Compound in Selected Drugs Using X-ray Study and Thermal Analysis

Abstract: Twelve drugs containing sildenafil compounds (sildenafil citrate and sildenafil base) were examined using X-ray studies and thermal analysis. According to the manufacturer’s information, the presence of sildenafil was confirmed in all investigated drugs. The positions of diffraction lines (value of 2θ angle) agree with the patterns presented in the ICDD database, Release 2018 (ICDD—International Centre of Diffraction Data). The difference expresses the agreement in the position of the diffraction line between … Show more
