At sci.med.psychobiology, "Samson" found a mistake in my original post.
Samson said: "Zolpidem is not only not a benzodiazepine, but
it_is_contraindicated with ritonavir (Abbott's protease inhibitor,
Norvir)."
Samson's comment is correct. I had intended to use this citation to
show the common mechanism, i.e., that drugs increase prolactin and,
therefore, possibly DHEA.
