citalopram + pentoxifylline

Citalopram + pentoxifylline is a combination therapy used for treating major depressive disorder (MDD). Citalopram is a selective serotonin reuptake inhibitor (SSRI) that works by increasing serotonin levels in the brain to improve mood and reduce anxiety. Pentoxifylline is a phosphodiesterase inhibitor with anti-inflammatory properties. When used together, this combination has shown improved efficacy in reducing depressive symptoms compared to citalopram alone, likely due to pentoxifylline's ability to reduce pro-inflammatory activities. Clinical studies have demonstrated that patients receiving this combination had better response and remission rates, along with significant reductions in pro-inflammatory markers and increases in serotonin and brain-derived neurotrophic factor (BDNF) levels.
