Detailed explanation-1: -Escitalopram (Lexapro) Fluoxetine (Prozac) Paroxetine (Paxil, Pexeva) Sertraline (Zoloft)
Detailed explanation-2: -SARIs work by inhibiting serotonin reuptake in the brain. They act as antagonists to inhibit a certain serotonin receptor-known as the 5HT2a receptor-and block the function of the serotonin transporter protein, thereby increasing the amount of active serotonin throughout the central nervous system (CNS).
Detailed explanation-3: -Fluoxetine and all other SSRIs are 5-HT2B Agonists-Importance for their Therapeutic Effects.
Detailed explanation-4: -SSRIs-such as Lexapro, Celexa, Zoloft, Paxil and Prozac-are believed to alleviate symptoms of depression, excessive worry and compulsivity by acting upon the brain’s chemistry-specifically by blocking the breakdown and reabsorption of the neurotransmitter serotonin in the spaces between neurons.
Detailed explanation-5: -Selective serotonin reuptake inhibitors (SSRIs) are a widely used type of antidepressant medication. They’re mainly prescribed to treat depression, particularly persistent or severe cases, and are often used in combination with a talking therapy such as cognitive behavioural therapy (CBT).
