Clozapine is a unique compound belonging to a relatively new group of antipsychotic agents, the dibenzazepines. To our knowledge, the present study represents the first double-blind, controlled comparison recorded in the United States. The data suggest that clozapine in the present population of newly admitted, acutely psychotic schizophrenic individuals, and in the doses employed, was more effective in overall improvement response, discharge rate, and ameliorating discrete symptoms across the different objective rating scales used than was chlorpromazine (Thorazine) hydrochloride. Placebo was ineffective. Unlike chlorpromazine, no extrapyramidal reactions occurred in those patients ingesting clozapine. Clozapine was also beneficial in reversing abnormal involuntary motor movements. It is an excellent anxiolytic and hypnotic agent. Sedation, hypotension, and hypersalivation are among the more common side effects observed.

We evaluated the functional sensitivity of the gamma-aminobutyric acid-benzodiazepine supramolecular complex in 9 patients with panic disorder and 10 psychiatrically healthy control subjects by comparing the effects of four logarithmically increasing doses of intravenous diazepam on saccadic eye movement velocity, memory, and self-rated sedation. Patients with panic disorder were less sensitive than controls to diazepam using eye velocity as the dependent measure. Sedation and memory effects did not distinguish the two groups. These findings suggest that panic disorder is associated with functional subsensitivity of the gamma-aminobutyric acid-benzodiazepine supramolecular complex in brain-stem areas controlling saccadic eye movements.

Healthy adult volunteers (n = 52) received single oral doses of flurazepam hydrochloride (15 mg), temazepam (15 mg), triazolam (0.25 mg), or placebo in a parallel, double-blind study. Sedative effects were greatest with triazolam, followed next by temazepam; peak effects closely coincided with peak plasma concentrations. Differential recovery from sedation corresponded in part to differences in mean elimination halflife, although sedative effects returned to baseline before plasma drug concentrations became undetectable. Sedation following flurazepam administration was less intense than with triazolam and temazepam. When tested at three hours after dosing, none of the active treatments impaired learning of a 16-item word list. However, at 24 hours, triazolam recipients could not recall a significant fraction of what was learned. Thus, dynamic differences among three benzodiazepine hypnotics may be partly explained by kinetic differences, as well as, we should caution, by possible "clinical inequivalence" in dosage.

In a multicenter placebo-controlled study, the safety, side effects, and patient acceptance of alprazolam for the treatment of panic disorder and agoraphobia were examined. A total of 525 patients meeting DSM-III criteria for agoraphobia with panic attacks or panic disorder were randomly assigned to receive alprazolam or placebo, which they took for eight weeks. The mean daily dose at the end of the study was 5.7 mg of alprazolam or 7.5 capsules of placebo daily. Potentially serious reactions to alprazolam occurred in ten of 263 subjects who received the drug. These included acute intoxication (three), hepatitis (two), mania (two), amnesia (one), aggressive behavior (one), and depression (one). Treatment-related side effects that were worse in patients taking alprazolam than in those taking placebo included sedation, fatigue, ataxia, slurred speech, and amnesia. Sedation was the most frequent but tended to subside with dose reduction or continued administration of the drug. Patient acceptance of alprazolam, as measured by the rate of completion for study participants, was high. Eighty-four percent of patients receiving active drug completed the study compared with 50% receiving placebo.

Oxazepam and diazepam were compared in healthy elderly volunteers. Absorption of diazepam was faster than oxazepam and onset of clinical effects were more profound. Diazepam accumulation was extensive, washout was slow and active compounds were present two weeks after the last dose. Oxazepam accumulation was significantly less and elimination significantly faster than diazepam. There was no difference between oxazepam and diazepam in sedation or fatigue during the drug treatment, but sedative effects persisted for two weeks after diazepam therapy was discontinued. Sedation rapidly returned to baseline in the oxazepam group. Thus, the differing pharmacokinetic profiles of diazepam and oxazepam have clinical consequences during multiple dosage in the elderly.

The relation between the stimulating and the sedating effects of acute alcohol consumption on human physical aggression was examined. Sixty male social drinkers were assigned to either an alcohol or a sober group. Aggression was measured using a modified version of S. Taylor's (1967) aggression paradigm, in which electric shocks are received from and administered to a fictitious opponent during a competitive task. Aggression was operationalized as the intensity and the duration of the shocks selected. Stimulation and sedation were measured using a self-report inventory. Results demonstrated that stimulation was positively related to aggression, but only in the intoxicated state. Sedation was not related to aggression in either the intoxicated or the sober state.

Fear of dentistry is a pervasive and persistent phenomenon that contributes to avoidance of dental care and results in a substantial public health problem. While the use of incremental enteral sedation has increased, there is a paucity of published evidence to evaluate its safety. This study sought to assess the safety of individualized dosing of enteral sedation for adults in the dental outpatient setting. The authors sent a mail survey to members of the Dental Organization for Conscious Sedation (DOCS) concerning their practice and practitioner characteristics. Anonymous treatment forms with monitoring records were collected from respondents and analyzed for pre-specified adverse event criteria. The majority of respondents reported practicing incremental enteral sedation for two to five years, accounting for less than 10% of their practice. Incremental enteral sedation, either alone or in combination with nitrous oxide and oxygen, was used most frequently. Monitoring with both pulse oximetry and automated blood pressure (BP) were prevalent. Triazolam was the drug used most commonly for enteral sedation. Of the 7740 cases submitted, 1686 (21.8%) met event criteria; the most frequent event was a decrease of more than 25% in diastolic BP from pre-drug baseline. Neither provider training nor the percentage of practices engaged in incremental enteral sedation were associated with any event; however, practicing incremental enteral sedation for less than 12 months was a significant predictor of any event (p = 0.001). Risk of having an event was not related to practice factors (that is, the time spent practicing incremental enteral sedation, the percentage of the practice devoted to practicing incremental enteral sedation, the number of cases performed, or the type of monitoring) or training factors. This survey represents the largest number of subjects reported in the literature concerning enteral sedation. These observations provide evidence for the safety of enteral sedation when these drugs and combinations are administered by properly-trained dentists who monitor patients with pulse oximetry, BP measurement, and direct observation.

Conscious sedation has become an integral part of dentistry; it is often used to reduce anxiety or fear in some patients during oral surgery, periodontal surgery, implant placement, and general dentistry procedures. The purpose of this study was to evaluate the frequency of adverse events during IV conscious sedation provided by credentialed general dentists and periodontists in the United States Air Force (USAF). Sedation clinical records (Air Force Form 1417) from calendar year 2009 were requested from all USAF bases. A total of 1,468 records were reviewed and 19 adverse events were noted in 17 patients. IV complication (infiltration) was the most common adverse event. The overall adverse event rate was 1.3 per 100 patients treated. The results of this study show that moderate sedation provided by general dentists and periodontists in the USAF has a low incidence of adverse events, and conscious sedation remains a viable option for providers for the reduction of anxiety in select patients.
