*α value. α is defined as the ratio of the cumulative effect of 2 therapies, PDT and drug, administered independently to the net effect of combining the 2 therapies at a given dose. If α > 1, the result is synergistic (supra-additive). If α < 1, the result is antagonistic, and if α = 1 the result is simply additive.
