Serotonin is a neurotransmitter that carries messages over the gap (synapse) between nerve cells. SSRIs increase the amount of serotonin that remains in the gaps (synapses).
Normally, serotonin, a neurotransmitter, is released and taken back in by presynaptic cells. SSRIs inhibit the "reuptake" of serotonin which floods the areas between synapses with serotonin. This results in decreased serotonin production, but a higher ratio of serotonin to serotonin receptors in the synapses. The brain, over time, takes time to adapt to this situation which is why antidepressants take a few weeks to take effect and why at first they often cause increased anxiety.
Tablets:10mg, 20 mg, 40 mg.
