Figure 8.

Forced acid degradation of brand (A) and generic (B) SFG containing 0.18 mM elemental iron diluted in 0.9% NaCl, 0.24 M HCl solution. At t = 0 h, the drug is fully intact. Each point represents the average of three measurements taken at 287 nm on a UV–visible spectrometer. Data were fitted to a one phase exponential decay plot (R² brand = 0.999 and R² generic = 0.997).
