selegiline

Selegiline is an artificial chemical that has an anti-depressive effect. It acts as a selective MAO-B (monoamine oxidase B) inhibitor, such that it prevents the enzymatic breakdown of dopamine and phenylethylamine.

Selegiline was invented in 1964. Selegiline is a much more effective antidepressant than the SSRIs, but it is so old that it has no patent on it. Consequently, the major pharmaceutical companies, and the psychiatrists who they pay, make no mention of it, because they can not use it to rake in the huge profit margins that they get from their patented chemicals. The Food and Drug Administration (FDA), which is really little more than a tool for the major pharmaceutical companies, didn't even approve of selegiline for use against major depression until 2006, after the patents on the various SSRIs had expired.
