Figure 4. UV spectrum of ibuprofen in different receiver compartments of the skin PAMPA assembly

UV spectrum of ibuprofen in different wells of the receiver compartment of the skin PAMPA plate assembly after 60 min of incubation; top left, top right, bottom left and bottom right graphs correspond to Formulas A, B, C and slurry formulations in donor wells (n ≥ 12 for each form). Note: the same absorbance scale for all forms eases the comparison.
