Placebo Comparator
Pentoxifylline + Standard Treatment
Placebo + Standard Treatment
Pentoxifylline: Pentoxifylline is phosphodiesterase inhibitor that interferes with proinflammatory cytokine signaling and synthesis. Participants will be instructed to take pentoxifylline 400 mg p.o. t.i.d. for 12 weeks. Standard Treatment: Beating the Blues (BtB) is a widely used, empirically supported, computer-based, CBT program for depression designed for use in primary care clinics. BtB utilizes an interactive, multimedia format to deliver and eight 50-minute, weekly therapy sessions.
Placebos: Placebo pills will match the study drug for color, taste, texture, size, and smell. Participants will receive the same instructions as those randomized to pentoxifylline. Standard Treatment: Beating the Blues (BtB) is a widely used, empirically supported, computer-based, CBT program for depression designed for use in primary care clinics. BtB utilizes an interactive, multimedia format to deliver and eight 50-minute, weekly therapy sessions.
