Ritanserin, a long-acting specific 5-HT2 receptor antagonist, revealed promising effects on alcohol intake behavior in both animal and preliminary human studies. To test its effectiveness in alcohol dependence this phase III clinical trial was initiated. In a placebo-controlled, randomized, double-blind international multicenter study 493 patients with moderate or severe alcohol dependence (DSM-III-R) were treated with three doses of ritanserin 2.5 mg/day (n = 122), 5 mg/day (n = 123), 10 mg/day (n = 126), or placebo (n = 122) over a period of 6 months. Ritanserin was well tolerated. The most frequent adverse experiences were headache and insomnia. A small increase in weight in the ritanserin-treated patients was observed. There were no significant differences between any dose of ritanserin and placebo in the relapse-rate, the time to relapse, craving for alcohol, or quantity and frequency of drinking after relapse. So far, neither ritanserin nor any other serotonergic medication has shown its specific effectiveness in relapse prevention in alcohol dependence.

Sleep disorders, such as insomnia and nightmares, are common problems in post-traumatic stress disorder (PTSD), exert a strong negative influence on the quality of life and are a great challenge for clinical psychiatry. Several studies have reported on the efficacy of drugs for the treatment of PTSD-related sleep disorders. These studies have not been systematically reviewed. This is the first review on the effectiveness of sleep medication in PTSD. We performed a Medline, EMBASE and Cochrane Library Indexed search, using the keywords: PTSD, pharmacotherapy, therapy, sleep, nightmares, insomnia and review. From this database, English-language, human subject, data driven papers published after 1980 were selected. Forty eight articles are discussed. Open-label and case studies suggest efficacy for some antidepressants, anticonvulsants and atypical antipsychotics. Only a few placebo-controlled studies have been published. They show promising results for the atypical antipsychotic olanzapine, and the alpha1-adrenoceptor antagonist prazosin. In comparison to the incidence and impact of sleep complaints in PTSD, the pharmacotherapeutic armamentarium for PTSD-related sleep complaints remains poorly investigated. Some recent studies show promising results, especially for alpha1-adrenoceptor and 5-HT2 receptor antagonists. However, randomized controlled trials with larger populations need to be conducted.

Objective: Selective serotonin reuptake inhibitors (SSRIs) have been the most widely used psychopharmacological agents prescribed for depression worldwide. Some adverse effects of SSRI drugs on central nervous system are insomnia and bruxism. These drugs also affect sleep. Quetiapine is used as adjunctive therapy to antidepressants for the treatment of major depressive disorder (MDD). It is a low- dose dibenzothiazepine with more potent 5-HT2 than D2 receptor-blocking properties that can be used to manage bruxism because of its antagonist effect on the 5-HT2 receptor. Cases: The cases were 5 patients who have recently been treated with SSRIs and presented with bruxism. Low- dose quetiapine (between 25 and 50 mg daily) was prescribed for the patients, and after a few days, they reported no bruxism and continued taking the medication. Conclusion: We found that quetiapine can improve bruxism and mandibular dystonia, which are side effects of SSRIs.
