paroxetine + trazodone

Paroxetine + trazodone is a combination of two antidepressant medications, each with distinct but complementary mechanisms of action. Paroxetine is a selective serotonin reuptake inhibitor (SSRI) that increases serotonin levels in the brain by inhibiting its reuptake into presynaptic neurons, primarily used for major depressive disorder, anxiety disorders, and related conditions[4][8]. Trazodone is classified as a serotonin antagonist and reuptake inhibitor (SARI); it acts by both inhibiting the reuptake of serotonin and antagonizing certain serotonin receptors (notably 5-HT2A), as well as providing antihistaminic effects that contribute to its sedative properties[5][2]. The combination may be considered in treatment-resistant depression or when targeting residual symptoms such as insomnia. However, this combination carries an increased risk for additive central nervous system depression and potential for serotonin syndrome; careful monitoring is required[1][2].
