Escitalopram is a selective serotonin reuptake inhibitor prescribed mainly for depression. It is used clinically to treat major depressive disorder and generalized anxiety disorder. The medication works by blocking the neuronal reuptake of serotonin, thereby raising its levels in the synaptic space. This increase enhances serotonergic signaling leading to improved mood regulation. Selective inhibition of the serotonin transporter sustains these signals and activates downstream receptors such as 5-ht1a. The resulting receptor activation contributes to the reduction of depressive and anxious symptoms. Overall the drug provides mood stabilization with fewer side effects compared with older agents.

Escitalopram is a selective serotonin reuptake inhibitor used to treat depression and anxiety. Its pharmacological action involves blocking the reabsorption of serotonin in the brain. By increasing the availability of serotonin in the synaptic cleft it enhances serotonergic signaling. This prolonged signaling helps improve mood and reduce excessive worry over time. The medication's effect is mediated through the serotonin transporter protein which normally clears serotonin after release. The resulting neurochemical balance supports emotional regulation without direct stimulation of receptors.

Escitalopram is a selective serotonin reuptake inhibitor used to treat depression and anxiety disorders. It works by increasing the amount of serotonin available in the brain. Common side effects include nausea, headache, and difficulty sleeping. Some people may experience drowsiness, dry mouth, or dizziness. Weight changes such as gain or loss can also occur. Sweating, tremor, and vivid dreams are reported less frequently but still observed. Sexual dysfunction including decreased libido or difficulty achieving orgasm has been noted. Most of these effects are mild and often improve after the body adjusts to the medication.

Escitalopram may cause nausea in some patients. Headache is another frequently reported symptom. Some individuals experience difficulty sleeping or feeling unusually tired. Dizziness and dry mouth also appear in clinical observations. Changes in sexual desire or function have been noted as common reactions. These effects are generally mild and often diminish with continued treatment.
