The short-acting clomethia2ole [533-45-9] (1), sometimes used as therapy for sleep disorders ia older patients, shares with barbiturates a risk of overdose and dependence. Antihistamines, such as hydroxy2iae [68-88-2] (2), are also sometimes used as mild sedatives (see HiSTAMlNES AND HISTAMINE antagonists). Antidepressants and antipsychotics which have sedative effects are used to treat insomnia when the sleep disorder is a symptom of some underlyiag psychiatric disorder.

The older adult is at greater risk for oversedation, dizziness confusion, or ataxia (unsteady gait) when taking a sedative or hypnotic. The nurse checks elderly and debilitated patients for marked excitement, CNSdepression, and confusion. If excitement or confusion occurs the nurse observesthe patient at frequent intervals (as often as every 5-10 minutes may be necessary) for the duration of this occurrence and institutes safety measuresto prevent injury. If oversedation, extreme dizziness or ataxia occurs the nurse notifies the primary health care provider. 

However, lorazepam and oxazepam are relatively safe for older adults when given in normal dosages. Buspirone (BuSpar) also is a safe choice for older adults with anxiety because it does not cause excessive sedation, and the risk of falling is not as great. Before bus-pirone therapy is begun, benzodiazepines and sedatives and hypnotics are gradually withdrawn. Buspirone, unlike most of the benzodiazepines, must be taken regularly and is not effective on an as-needed basis. 

There is an increase in anticholinergic effects when antihistamines are administered with the monamine oxidase inhibitors (MAOIs) and additive sedative effects if administered with central nervous system depressants (eg, narcotic analgesics or alcohol). When cimetidine and loratadine are administered together there is a risk for increased loratadine levels. 

The antidiarrheal drugs cause an additive CNS depression when administered with alcohol, antihistamines, narcotics, and sedatives or hypnotics. There are additive cholinergic effects when administered with other drugp having anticholinergic activity, such as antidepressants or antihistamines. Concurrent use of the antidiarrheals witii a monoamine oxidase inhibitor increases the risk of a hypertensive crisis. 

There is an increased risk for bone marrow suppression when levamisole or hydroxyurea are administered witii other antineoplastic dni. Use of levamisole witii phenytoin increases die risk of phenytoin toxicity. Pegaspargase may alter drug response of the anticoagulants. When procarbazine is administered with other central nervous system (CNS) depressants, such as alcohol, antidepressants, antihistamines, opiates, or the sedatives, an additive CNS effect may be seen. Procarbazine may potentiate hypoglycemia when administered witii insulin or oral antidiabetic dru . ... 

Benzodiazepines and similar agents occupy a position of intermediate abuse potential, compared with most other sedative-hypnotics (Griffiths and Weerts 1997). Animal models of abuse habihty indicate that the reinforcing effects of benzodiazepines are less pronounced than are those of the barbiturates, opioids, and stimulants. Differences in abuse potential within the class have not been consistently demonstrated however, most chnicians agree that benzodiazepines with a rapid onset and short duration of action pose the greatest risk in susceptible individuals. 

There is, however, a unique risk in the bipolar form that antidepressant treatment may trigger a switch into mania. This may occur either as the natural outcome of recovery from depression or as a pharmacological effect of the drug. Particular antidepressants (the selective serotonin reuptake inhibitors) seem less liable to induce the switch into mania than other antidepressants or electroconvulsive therapy. Treatment for mania consists initially of antipsychotic medication, for instance the widely used haloperidol, often combined with other less specific sedative medication such as the benzodiazepines (lorazepam intramuscularly or diazepam orally). The manic state will usually begin to subside within hours and this improvement develops further over the next 2 weeks. If the patient remains disturbed with manic symptoms, additional treatment with a mood stabilizer may help. 

The oldest anti-anxiety agent is undoubtedly alcohol and it is certain that this drug is still routinely self-administered for this purpose. Towards the end of the eighteenth century, bromide salts were used to relieve conditions akin to anxiety despite the risk of a characteristic toxic delirium, known as bromism . Alternative treatments, such as paraldehyde and chloral hydrate, were also widely used but these too had adverse effects the former can cause psychosis but the latter is still used as a sedative and anaesthetic agent. 

A number of medications have been associated with an increased risk of falling, including drugs affecting mental status such as antipsychotics, benzodiazepines, tricyclic antidepressants, sedative-hypnotics, anticholinergics, and corticosteroids. Some cardiovascular and antihypertensive drugs also can contribute to falls, especially those causing orthostatic hypotension.9... 

Anticonvulsant A drug used in the treatment of epilepsy, and to reduce the risk of seizures during detoxification from sedative-hypnotics. More recently these drugs have been used in the clinical management of bipolar disorders. 

The benzodiazepines that have been most commonly marketed as sedative-hypnotics include temazepam (Restoril), estazolam (ProSom), flurazepam (Dalmane), quazepam (Doral), and triazolam (Halcion). Of these five, temazepam is the most easily metabolized and eliminated. Therefore, temazepam is preferred for elderly and medically ill patients to minimize the risk of drug accumulation. 

Antidepressants. Depression after TBl is routinely treated with antidepressant medicines. Although all antidepressants are potentially helpful, antidepressants prone to burdensome side effects, particularly sedative and anticholinergic side effects, should generally be avoided, as they are likely to be tolerated poorly by these patients. In addition, antidepressants that may increase the risk for seizure, such as many of the older tricyclic antidepressants (TCAs) and bupropion (Well-butrin), should be avoided because post-TBl patients as a rule are already more vulnerable to seizures. 

Flumazenil is a benzodiazepine antagonist that is used in anaesthesia for the reversal of central sedative effects of benzodiazepines. It should not be administered rapidly so as to avoid patient wakening too rapidly, which can lead to agitation, anxiety, fear and convulsions, particularly in high-risk patients, e.g. those with a history of epilepsy or head injury.
