Major Research Findings

Roflumilast is a phosphodiesterase 4 (PDE4) inhibitor used to treat chronic obstructive pulmonary disease (COPD). Research indicates that roflumilast can reduce inflammation and improve lung function, but its long-term safety and efficacy are still under investigation.

Roflumilast has been found to have beneficial effects in various conditions like asthma, COPD, Alzheimer's disease, and Huntington's disease. 2 , 7 , 10 , 8 , 18 , 15 , 12 , 6 It has also been shown to reduce neuroinflammation and improve cognitive function. 10 , 18 , 6 Research suggests that roflumilast can improve heart function and reduce diabetes-related cardiac remodeling. 5 Roflumilast has also been reported to modulate immune cell activity and alleviate symptoms of allergic asthma and hypersensitivity pneumonitis. 13 , 3 However, roflumilast may lower testosterone levels, potentially impacting male reproductive function. 1 Roflumilast may also contribute to weight loss and improved insulin sensitivity, but adverse effects like nausea and vomiting have been reported. 16 , 17
