  In this communication we draw attention on serious flaws that plague recently
reported antioxidant properties of atorvastatin (ATV) in methanol. First and
foremost, we emphasize that the O-H bond dissociation energies (BDE) of about
400\,kcal/mol previously reported are completely wrong. Further, we present
results refuting the previous claim that the proton affinity (PA) of ATV is
smaller than that of the ascorbic acid. That unfounded claim relies on
  incorrect data for PA's ascorbic acid (which we correct here) circulated in
the literature. Further, we correct the values of the chemical reactivity
indices (e.g., chemical hardness, electrophilicity index, electroaccepting and
electrodonating powers), which were inadequately estimated previously via
Kohn-Sham HOMO and LUMO energies. Finally, our updated values for \ce{O-H} bond
dissociation enthalpy (BDE = 91.4\,kcal/mol) and electron transfer enthalpy
(ETE = 105.7\,kcal/mol) tentatively suggest that direct H-atom transfer (HAT)
and sequential proton loss electron transfer (SPLET) may coexist.
