The spectrum of pure atazanavir is available in the supplementary figure (supplementary figure 1).
(a) Morphological analysis showed unusual fragments, yellowish in color, finely rough, and friable. Cross-section was relatively well organized, with porous structure and radial crystallization locations. (b) Infrared spectrum of atazanavir, C1, and proteins observed after crushing the stone and FTIR spectroscopy analysis (Bruker Optics, Germany). Arrows indicate places where C1 is identifiable in the main spectrum of atazanavir.

FTIR analysis revealed that the calculus was predominantly constituted of atazanavir (>70%), with a low proportion of monohydrated calcium oxalate (C1) and proteins (<30%) (Figures 2(a) and 2(b)).
