💊 Selective serotonin reuptake inhibitors (SSRIs) work by inhibiting 5-HT reuptake by the presynaptic cleft, thus increasing serotonin levels in the synapse.⁠ It is commonly used to treat depression, a condition thought to be linked to low levels of serotonin, dopamine, and norepinephrine. ⁠ ⁠ ⭐ As you can see, this mnemonic is similar to the mnemonic on the side effects of SNRIs. Since they both block serotonin reuptake, they exhibit very similar side effect profiles except SNRIs can also impact blood pressure (increase or decrease) due to the norepinephrine reuptake inhibition. SSRIs do not affect blood pressure. ⁠ ⁠ In addition, SSRIs can cause weight gain in adults on long-term therapy, while SNRIs cause less of this long-term weight gain and are more associated with weight loss. ⁠
