(SSRIs) A relatively new class of drugs that are used to treat depression. They work by blocking the reabsorption of the neurotransmitter serotonin following its release in the brain. The increased serotonin levels that result are associated with improved mood. Common drugs in this group include fluoxetine and sertraline. SSRIs are usually taken orally once a day; it may take 1–3 weeks for any noticeable improvement in symptoms. SSRIs usually produce fewer side effects than other types of antidepressant drug. However, they may cause diarrhoea, nausea, restlessness, and anxiety.
