Main Research Findings

Ramelteon has been shown to have several beneficial effects, including improving sleep, reducing inflammation, and protecting against oxidative stress. In a study using a rat model of metabolic syndrome, ramelteon reduced body weight gain, heart damage, and improved insulin signaling in adipose tissue. 10

Ramelteon was also found to protect brain endothelial cells from damage caused by isoflurane, a common anesthetic. It reduced oxidative stress and inflammation in these cells, which could potentially be beneficial for preventing cognitive impairment after surgery. 4

Ramelteon, along with agomelatine, has been shown to improve bone fracture healing in rats. These drugs increased the expression of bone formation markers and accelerated fracture healing. 6

Ramelteon was found to reduce the harmful effects of methotrexate, a chemotherapy drug, on brain cells in rats. It improved oxidative stress and reduced inflammation, apoptosis, and autophagy markers. 2

In a case report, ramelteon was used to treat a patient with circadian rhythm sleep disorder and mood disorder. The patient showed improvement in sleep and mood after taking ramelteon. 15

Ramelteon has also been shown to improve sleep disturbances in patients with Parkinson's disease, particularly rapid eye movement sleep behavior disorder (RBD). 14

One study found that ramelteon was effective at preventing delirium after elective liver resection. 5

Another study found that ramelteon reduced the number of benzodiazepines used by patients with insomnia. 9

Ramelteon was also shown to be effective at preventing delirium in elderly patients admitted to the hospital for acute care. 18

Ramelteon was shown to have beneficial effects on cognitive function in patients with schizophrenia. 16

A study investigating the effects of ramelteon on driving performance, cognitive function, and equilibrium found that ramelteon may have some negative effects on driving and cognitive function in acute doses. 17

Ramelteon was found to be effective at preventing delirium in older patients undergoing orthopedic surgery. 7
