Share this article Share Fathead minnows usually display complex mating behavior, with males building the nests where females comes to lay their eggs. Klaper said that the fluoxetine, the active ingredient in Prozac, was given in very low concentrations - 1 part per billion - which is the same as that found in waste water discharged into waterways. The romance is gone: The usually-elaborate reproductive habits of the fathead minnow are altered by exposure to Prozac, with males becoming aggressive and sometimes killing females The male of the species spent more time hiding alone, hunting and ignoring females.

Pharmacodynamics[ edit ] Fluoxetine is a selective serotonin reuptake inhibitor SSRI and does not appreciably inhibit norepinephrine and dopamine reuptake at therapeutic doses.

It does, however, delay the reuptake of serotonin, resulting in serotonin persisting longer when it is released. Large doses in rats have been shown to induce a significant increase in synaptic norepinephrine and dopamine.

What Events Happened in 1988

However, the significance of this property is not fully clear. CYP2D6 is responsible for converting fluoxetine to its only active metabolite, norfluoxetine. Norfluoxetine concentrations are approximately equal to those of the parent drug during chronic therapy, but may be substantially less following acute overdosage, since it requires at least 1—2 weeks for the metabolite to achieve equilibrium.

It was known at that time that the antihistamine diphenhydramine shows some antidepressant-like properties. Wongproposed to retest the series for the in vitro reuptake of serotonin, norepinephrine and dopamine.

The other permitted antidepressants are sertraline Zoloftcitalopram Celexaand escitalopram Lexapro.

The most popular antidepressants are selective serotonin reuptake inhibitors, or SSRIs. This group includes some of the most popular prescription drugs on the planet such as Zoloft, Prozac, Celexa, Lexapro, and Paxil.

A decade has passed since we first published aquatic toxicology studies of fluoxetine. • Our report of the SSRIs fluoxetine and sertraline in fish was termed “Fish on Prozac”.
