Depression is often currently treated with selective serotonin reuptake inhibitors (SSRIs) ...

Serotonin – a messenger chemical also thought to influence mood – carries its signal from one neuron to the next

SSRIs

SSRIs block reabsorption sites, raising serotonin levels in the synapse and increasing its effect
... a new ketamine infusion therapy nasal spray can help treat patients much faster

Ketamine – an anaesthetic and analgesic – allows serotonin and other chemicals to work normally and does not block reabsorption sites

Instead it is thought to stimulate the development of new receptors of various types and so increase the effectiveness of signalling between neurons
