Introduction to Rozerem (Ramelteon)
Rozerem, known generically as ramelteon, is a melatonergic agent used primarily for the treatment of insomnia, particularly for individuals who have difficulty falling asleep. It works by selectively binding to the MT1 and MT2 receptors in the suprachiasmatic nucleus (SCN), mimicking the action of melatonin, the hormone that regulates the sleep-wake cycle[4].
Clinical Trials and Efficacy
Insomnia Treatment
Clinical trials have demonstrated the efficacy of Rozerem in treating insomnia characterized by difficulty with sleep onset. These trials, which lasted up to six months, showed significant improvements in sleep latency and overall sleep quality. The final formal assessments of sleep latency were performed at various intervals, including after two days, five weeks, and at the end of the six-month study[3].
Prevention of Delirium
Ramelteon has also been studied for its preventive effects on delirium, particularly in elderly patients and those in intensive care units (ICUs). A randomized controlled trial found that ramelteon administered nightly to elderly patients admitted for acute care may provide protection against delirium. The study observed a significant reduction in the occurrence of delirium in the ramelteon group compared to the placebo group[1].
Another study conducted in an ICU setting showed that ramelteon tended to decrease the duration of ICU stay and statistically significantly decreased the occurrence rate and duration of delirium in ICU patients[5].
Adverse Events and Safety Profile
Clinical trials have identified several adverse events associated with Rozerem, including somnolence, dizziness, fatigue, nausea, headache, and insomnia. These events were generally mild and led to discontinuation in a small percentage of patients. Serious adverse reactions include severe anaphylactic and anaphylactoid reactions, abnormal thinking, behavior changes, and CNS effects[3].
