Fluoxetine, a widely used selective 5-HT reuptake inhibitor (SSRI), selectively inhibits 5-HT transporters and blocks pre-synaptic membrane reuptake of 5-HT. Prolongs and increases the effects of 5-HT, resulting in an antidepressant effect. The affinity for adrenergic, histamine, and cholinergic receptors is low, and the effect is weak, resulting in fewer adverse reactions. After oral administration, the absorption is good, the bioavailability is 70%, easy to pass the blood-brain barrier, and a small amount can be secreted into the milk. It is metabolized by CYP2D6 in the liver to produce mefoxetine, which also has antidepressant effects.
