Fluoxetine

Fluoxetine, commonly known by its brand name Prozac, is a widely prescribed antidepressant medication. It belongs to a class of drugs called selective serotonin reuptake inhibitors (SSRIs). Fluoxetine works by increasing the levels of serotonin in the brain, a neurotransmitter that plays a crucial role in regulating mood, sleep, appetite, and other important functions.

Chemical Structure and Properties

Fluoxetine’s chemical formula is C₁₇H₁₈F₃NO. It is a white to off-white crystalline powder that is practically insoluble in water. Fluoxetine is a chiral molecule, meaning it exists in two mirror-image forms (enantiomers). The S-enantiomer is the active form of the drug, while the R-enantiomer is inactive.

History of Discovery and Development, Prozac generic

Fluoxetine was discovered in 1974 by Eli Lilly and Company. It was initially developed as an anti-obesity drug but was found to have antidepressant properties. Fluoxetine was approved by the U.S. Food and Drug Administration (FDA) in 1987 for the treatment of major depressive disorder.

Mechanism of Action

Fluoxetine works by inhibiting the reuptake of serotonin in the brain. Serotonin is a neurotransmitter that is involved in regulating mood, sleep, appetite, and other important functions. When serotonin is released from a neuron, it binds to receptors on the receiving neuron, transmitting a signal. After the signal is transmitted, serotonin is normally reabsorbed back into the transmitting neuron, a process called reuptake.

Fluoxetine blocks the serotonin transporter protein, which is responsible for reuptake. This prevents serotonin from being reabsorbed, leading to increased levels of serotonin in the synaptic cleft, the space between neurons.

The increased levels of serotonin in the synapse enhance serotonin’s effects on the receiving neurons, which helps to improve mood and reduce symptoms of depression.

Uses and Indications

Prozac, the brand name for fluoxetine, is a selective serotonin reuptake inhibitor (SSRI) antidepressant medication used to treat a variety of mental health conditions. It works by increasing the levels of serotonin, a neurotransmitter that plays a role in mood regulation, in the brain.
