You got me curious and I did a little reading.
"Cocaine is a strong and effective pain killer and widely used for anesthetizing mucous membranes of the nose, eyes and throat." The page was about thyroid and didn't say anything else relevant that I could find.
"it is a serotoninnorepinephrinedopamine reuptake inhibitor"
From a page about norepinephrine (NE): "The effects of several street drugs, including cocaine and illegal amphetamines, stem from increased NE levels and the resulting physical arousal and feelings of elation, which is part of what makes these drugs addictive."
About methylphenidate mentioned above: "Ritalin has been called "kiddy cocaine," as its effects are similar"
"chronic cocaine use is believed to cause catecholamine depletion"
"Provigil does the opposite. Provigil does several things, but is mostly an NMDA-activator it's a stimulant similar to cocaineit will actually stimulate nitric oxide production. It may also stimulate ATP generation, which is the benefit perhaps that one sees. With more nitric oxide, you can think better, your memory improves, you can focus better, and you have more energy. But what you're doing is generating more peroxynitrite and this may not be felt for a while, but ultimately it's probably feltin the brain at leastas Alzheimer's or Parkinson's Disease or worse, ten years from now."
"1884 - Sigmund Freud advocated cocaine use to alleviate chronic fatigue"
