Twenty-one depressed patients with probable Alzheimer's disease (AD) were randomized to receive a 6-week treatment with clomipramine or placebo in a study with a double-blind crossover design. Main outcome measures were Hamilton Depression, Mini-Mental State (MMSE), and Functional Independence Measure (FIM) scores. Mood improved significantly on both clomipramine and placebo, but clomipramine was significantly more effective than placebo during the first 6-week treatment period. Patients started on clomipramine maintained improvement during the washout and placebo periods, whereas patients started on placebo worsened during the washout period. However, patients on clomipramine showed significantly lower MMSE scores overall than patients on placebo. No significant drug effects were found on FIM scores. Clomipramine proved to be a useful treatment of depression in patients with probable AD. The efficacy of the serotonin (5-HT) uptake inhibitor clomipramine in the treatment of self-injurious behavior (SIB) was tested in individuals with severe and profound mental retardation. Six of the 8 subjects who completed a double-blind, placebo-controlled crossover trial exhibited a clinically significant improvement (50% or greater reduction from placebo) in the frequency of SIB. Clomipramine treatment was also associated with improvement in SIB intensity, frequency of stereotypy and compulsions, teacher ratings of stereotypy and social withdrawal, and frequency of staff intervention required for problem behaviors. Adverse effects (seizure and tachycardia/agitation) occurred in 2 of the 8 subjects. These results represent the first controlled trial of a 5-HT uptake inhibitor in the treatment of SIB in mental retardation. It is hypothesized that self-injurious behavior (SIB) and symptoms of autism may be due to overactivity in some opioid systems in the brain. We examined the efficacy and safety of naltrexone hydrochloride, an opioid antagonist, in the treatment of SIB and autism in mentally retarded adults.
                Thirty-three mentally retarded adults with autism and/or SIB participated in double-blind, placebo-controlled crossover studies. Active treatment was first a single 100-mg dose of naltrexone hydrochloride. Subsequently, 19 subjects were treated with 50 mg/d and 14 with 150 mg/d of naltrexone hydrochloride for 4 weeks. The outcome was assessed by means of direct observations (n = 11) and on the basis of scores on a list of target behaviors, the Aberrant Behavior Checklist, and the Clinical Global Impression Scale.
                Thirty-two subjects (seven with autism, 16 with autism and SIB, and nine with SIB) completed the trial. Naltrexone treatment failed to have therapeutic effects on SIB and autism. On the contrary, naltrexone increased the incidence of stereotypic behavior on the Aberrant Behavior Checklist, and the care staff evaluated the effect of the 50-mg/d treatment as being significantly worse than that of the placebo treatment as measured by the Clinical Global Impression Scale.
                Our findings suggest that naltrexone has no clinical value for a broad group of mentally retarded subjects with SIB and/or autism. To determine whether clomipramine hydrochloride, a serotonin reuptake blocker with unique anti-obsessional properties, is differentially effective for obsessive-compulsive and stereotyped motor behaviors in autistic disorder compared with placebo and with the noradrenergic tricyclic antidepressant agent, desipramine hydrochloride.
                Following a 2-week, single-blind placebo washout phase, 12 autistic subjects completed a 10-week, double-blind, crossover comparison of clomipramine and placebo, and 12 different subjects completed a similar comparison of clomipramine and desipramine.
                Outpatient clinic.
                A referral sample of 30 male and female autistic patients were enrolled, and 24 completed the study.
                Key outcome measures were the Autism Relevant Subscale of the Children's Psychiatric Rating Scale, the Modified Comprehensive Psychopathological Rating Scale-Obsessive-Compulsive Disorder Subscale, and the Clinical Global Impressions Scale.
                Clomipramine was superior to both placebo and desipramine on ratings of autistic symptoms (including stereotypies), anger, and compulsive, ritualized behaviors (P < .05), with no differences between desipramine and placebo. Clomipramine was equal to desipramine and both tricyclic agents were superior to placebo for amelioration of hyperactivity.
                Biological links between compulsions and stereotyped, repetitive behaviors in autistic disorder should be explored. Clomipramine, haloperidol, and placebo were compared with baseline in the treatment of autism, and overall outcome, specific symptoms, and side effects were examined. It was hypothesized that clomipramine would be better tolerated than haloperidol and prove superior on a measure of stereotypy. Individuals with a DSM-IV diagnosis of autistic disorder (mean age, 16.3 years; range, 10-36 years) were randomly assigned, by using a Latin square design, to the following 7-week trials: placebo, clomipramine (mean daily dose, 128.4 mg; range, 100-150 mg), or haloperidol (mean daily dose, 1.3 mg; range, 1-1.5 mg). Data on 36 subjects were analyzed and taken together; the results favored haloperidol. In those patients who were able to complete a full therapeutic trial, clomipramine proved comparable to haloperidol in terms of improvement compared with baseline. However, significantly fewer individuals receiving clomipramine versus haloperidol were able to complete the trial (37.5% vs. 69.7%, respectively) for reasons related to both side effects and efficacy or behavior problems. In the intent-to-treat sample, which is perhaps more clinically relevant, only haloperidol proved superior to baseline on a global measure of autistic symptom severity, as well as specific measures for irritability and hyperactivity. Clomipramine did not seem more effective on a measure of stereotypy, nor was it better tolerated. In a double blind study, out of 31 newly abstinent patients who underwent opioid free detoxification, 15 were started on the opiate antagonist Naltrexone for 2 months, and 16 were put on placebo for the same period. Given Naltrexone's known efficacy in blocking euphorigenic effects of opioid intake, and in decreasing cravings for the drug, the authors have tried to assess eventual drug taking, specifically in the context of suburban housing projects, and evaluate the rate of retention in a rehabilitative program for both the Naltrexone and placebo groups. An Opioid free condition was followed up for a year, also respecting double blind conditions. Naltrexone did not appear to be superior to the placebo with regards to retention rate. In the Naltrexone group (n = 15), 9 finished the two-month treatment, and 8 remained opioid-free for a year. In the placebo group (n = 16), 8 finished the 2 month trial and 6 remained opioid-free for a year. Naltrexone blocked opioid-induced euphoria and decreased the craving for opium, but it did not inhibit drug usage. The retention rate registered during the course of the study, as well as an opioid-free condition in the follow-up year, correlated with a patient profile defined by good social functioning and stable relationships. The inherent methodological limitations of this study did not allow for the discrimination of the role of non-pharmacological factors, such as psychotherapy, supportive family framework, community assistance, and staff motivation, concerning the clinical results. Further investigation of Naltrexone in larger samples is needed. Accumulated evidence shows that biology and the environment can mediate self-injurious behavior (SIB) in persons with mental retardation. Whether pharmacological treatment alters the environmental mediation of self-injury is unclear. Opioid antagonist effects on sequential dependencies for self-injury were studied in the context of experimental single-subject double-blind placebo-controlled designs. Direct observational data were collected for 4 adult subjects in real time on daily rate of SIB and staff interactions. Clinically significant reductions (i.e., > or = 33%) in SIB rate were observed for 3 of the 4 subjects. For all subjects, the magnitude of the sequential dependency between staff behavior and self-injury was significantly greater during treatment with naltrexone than during treatment with a placebo. Results are discussed in relation to behavioral mechanisms of action regulating medication effects for self-injury. 82 patients with chronic pain resulting from mononeuropathy were treated with psychotropic drugs in an open therapeutic study. In this study we found that treatment with a combination of clomipramine (Anafranil) and small doses of neuroleptics was significantly superior to therapy with neuroleptics alone. In a subsequent double-blind study, it was attempted for the first time to determine the efficacy of clomipramine compared to that of acetylsalicylic acid in 48 patients with painful mono- and polyneuropathies. The test was carried out in a cross-over trial with two sequence groups. We evaluated assessments of pain by both patients and doctors, and were able to prove statistically that clomipramine possesses a significantly greater efficacy compared to that of acetylsalicylic acid. By taking into account recent anatomical, biochemical and pharmacological studies, it can be concluded that clomipramine probably has-in addition to the action on peripheral receptors-a direct effect upon pain modulation systems. It seems possible that clomipramine activates serotonin-containing neurons of the endorphin-mediated analgesia system that control pain transmission in the CNS. The aim was to assess the effect of a flexible dose of paroxetine, compared with clomipramine and placebo, in obsessive-compulsive disorder (OCD).
                In a multinational randomised study, 406 subjects with OCD of at least six months duration received double-blind medication for up to 12 weeks. Doses were adjusted according to therapeutic effect and side-effects. Primary efficacy measures were the Yale-Brown Obsessive-Compulsive Scale and the National Institute of Mental Health Obsessive-Compulsive Scale. Secondary efficacy measures were the Montgomery-Asberg Depression Rating Scale, Symptom Check-List (90), Clinical Global Impression, and Patients Global Evaluation.
                Paroxetine was significantly more effective than placebo, and of comparable efficacy to clomipramine. Paroxetine had significantly superior tolerability to clomipramine on three measures: CGI efficacy index, anticholinergic adverse events, and adverse events leading to withdrawal.
                Paroxetine is as effective as clomipramine in the treatment of OCD. The comparable efficacy and better tolerability of paroxetine suggest that it would be an appropriate treatment for OCD.
There was weak evidence in included trials that any active drug was more effective than placebo for people with intellectual disability demonstrating SIB. Due to sparse data, an absence of power and statistical significance, and high risk of bias for four of the included trials, we are unable to reach any definite conclusions about the relative benefits of naltrexone or clomipramine compared to placebo.
