SSRIs also known as meds or happy pills are a drug therapy found to be an effective intervention in clinical depression and anxiety.
SSRIs help the seratonin on your brain to hang around longer through blocking the reuptake of it by the presynaptic neuron, thereby letting it build up to effective levels.
This increases serotonin signaling, which then acts to elevate mood and thus relieve depressive symptoms.
Some examples of SSRIs are:
- Citalopram (Celexa)
- Escitalopram (Lexapro)
- Fluoxetine (Prozac)
- Paroxetine (Paxil, Pexeva)
- Sertraline (Zoloft)
- Vilazodone (Viibryd)
I have can personally vouch for the effectiveness of sertraline.
