Which class of medications is commonly prescribed for the treatment of depression?

The class of medications commonly prescribed for the treatment of depression is SSRIs, or selective serotonin reuptake inhibitors. SSRIs work by increasing the levels of serotonin in the brain, a neurotransmitter that plays a crucial role in mood regulation. By preventing the reabsorption (reuptake) of serotonin in the synaptic gap between neurons, SSRIs help improve mood and alleviate symptoms of depression. This mechanism makes them particularly effective for many patients suffering from major depressive disorder as well as some anxiety disorders.

In clinical practice, SSRIs are often favored due to their favorable side effect profile compared to older classes of antidepressants, making them a first-line treatment option in many cases.
