And, it's safe.
I failed to mention in any way the utter safety of the Anavex drugs. Almost all of the drugs acting in the central nervous system have side effects of varying degrees, "adverse events" (AEs).
In any of the clinical tests of the Anavex sigma-1 receptor drugs, whether in murines (lab rodents) or in real humans, no obviating AEs have ever appeared, An infrequent circumstance among brain-acting drugs. Another Anavex positive.
