CSIC stability profiles: (a) at various pHs, (b) in 25 °C/60% RH and 65 °C environmental chambers and 3% H2O2 solutions, and (c) with or without light exposure (2 × 20 watts, fluorescent luminaire) in water (40% ACNH2O, v/v) or pH7 phosphate buffer solution (40% ACNpH7, v/v), respectively. Drug substance was found to be susceptible to oxidation and photolysis. (*p<0.05, n=3)
