Fluoxetine is an antidepressant of the selective serum reabsorption inhibitor (SSRI) type.The drug takes the form of Fluoxetine hydrochloride. Its trade name is "Prozac". The drug was developed by the Eli Lilly and Company. It has been launched into market for sale since the 1990s. This drug is used for the treatment of adult depression, obsessive-compulsive disorder, bulimia nervosa and the panic disorder that has or does not have the phobia of the square. It has good antidepressant effect and is widely used in clinical practice as a first-line antidepressant.The main pharmacological effect is to selectively inhibit the reuptake of 5 hydroxytryptamine (HT), which is released before the synapse of the central nervous system.It is also known as a selective 5- serotonin reuptake inhibitor. For other receptors, such as alpha adrenergic, beta adrenergic, 5- serotonin, and dopamine, fluoxetine had almost no binding force. Fluoxetine is well absorbed from the gastrointestinal tract after oral administration.The plasma concentration is about 6~8 hours, and eating does not affect its bioavailability. About 95% are combined with plasma proteins and are widely distributed.After taking the medicine for several weeks, the steady plasma concentration will be reached.By metabolism of the liver, the active metabolite, norfluoxetine is generated by demethylation. The half-life of fluoxetine is 4-6 days, and norfluoxetine is 4-16 days.It was mainly excreted by kidney. Because it can be secreted to breast milk, it is suggested to be cautious to pregnant women and breast-feeding women.
