What is an SSRI?

Explanation:
SSRI stands for Selective Serotonin Reuptake Inhibitor. These drugs block the transporter that normally reabsorbs serotonin back into the presynaptic neuron, leaving more serotonin available in the synaptic cleft to stimulate postsynaptic receptors. This increases serotonergic signaling and can help improve mood and anxiety symptoms over time. This mechanism is different from a serotonin receptor antagonist, which would block the receptors themselves; from a dopamine transporter blocker, which affects dopamine reuptake rather than serotonin; and from a GABA receptor modulator, which enhances inhibitory signaling via the GABA system. In veterinary practice, SSRIs like fluoxetine or sertraline are used for behavioral conditions and often take several weeks to show noticeable effects.
