Benzodiazepines indications

Lorazepam is a short-acting benzodiazepine indicated for use in relieving anxiety and insomnia. Lorazepam may also be administered perioperatively to alleviate pain and in status epilepticus. Imipramine is a tricyclic antidepressant, paroxetine is a selective serotonin re-uptake inhibitor, venlafaxine is a serotonin and adrenaline re-uptake inhibitor and moclobemide is a reversible monoamine oxidase inhibitor. Imipramine, paroxetine, venlafaxine and moclobemide are all classified as antidepressants. [Pg.292]

Benzodiazepines. Figure 3 Dissection of benzodiazepine pharmacology. The functional roles of GABAa receptor subtypes, mediating particular actions of diazepam, are indicated. A sign indicates that the respective response is mediated by the respective receptor subtype, a sign indicates that the respective response is apparently not mediated by the respective receptor subtype. ND = not determined. [Pg.253]

Control of early withdrawal symptoms, which prevents their progression to more serious symptoms, is the indication for which medications are most widely prescribed in the treatment of alcohol dependence. The most commonly used agents to treat alcohol withdrawal are the benzodiazepines, a class of drugs that, by virtue of their agonist activity at the GABA receptor complex, suppress the hyperexcitability associated with alcohol withdrawal. With widespread use of anticonvulsant medications for bipolar disorder and other disorders associated with behavioral disinhibition and CNS hyperexcitability, anticonvulsants have also been examined for use in the treatment of alcohol withdrawal. [Pg.18]

Antipsychotics are not indicated for the treatment of withdrawal, except when hallucinations or severe agitation are present (Naranjo and Sellers 1986), in which case they should be added to a benzodiazepine. In addition to their potential to produce extrapyramidal side effects, antipsychotics lower the threshold for seizures, which is particularly problematic during alcohol withdrawal. [Pg.19]

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. [Pg.127]

Clinical situations in which detoxification is indicated can be grouped into three categories 1) for patients who have been taking a maintenance therapeutic dosage for moderate to long periods of time and for whom a trial without medication is warranted, 2) for patients taking supratherapeutic doses (usually in the context of benzodiazepine dependence), and 3) for patients who use benzodiazepines as part of mixed substance dependence. Detoxification should be approached differently in each category. [Pg.130]

Patients requiring detoxification from high or supratherapeutic dosages of benzodiazepines constitute a smaller number of patients, but they are at greater risk for life-threatening discontinuation symptoms, such as seizures, delirium, and psychoses. There has been more experience with inpatient detoxification in this group, but outpatient detoxification is possible if conducted slowly (5% reduction in dose per week), with frequent contact, and in the context of a therapeutic alliance with the patient. Often, such an alliance proves unworkable because the patient s impoverished control results in supplementation from outside sources or early exhaustion of prescribed supplies meant to be tapered. In these cases, as in the cases of patients with a history of seizures, delirium, or psychoses during previous detoxification attempts, inpatient detoxification is indicated. [Pg.132]

As Shown in table 2, a comparative dose of 10 n units of PCP-like activity inhibited 3H-PCP binding in rat brain membranes, but did not inhibit binding of 3 H - d i hydromorphi ne, 3H - D - a 1 a2 - D -1 eu5-enkephalin, 3H-ethylketocyclazocine, 3H-diazepam, or -neurotensin. These results indicate that the active material is specific and selective from PCP receptors, as binding to the mu, delta, and kappa opioid receptors was unaffected, as was binding to benzodiazepine and neurotensin receptors. [Pg.41]

The answer is e. (Ka.tzu.ng, pp 373-3743 Flumazenil is a competitive benzodiazepine receptor antagonist. The drug reverses the CNS sedative effects of benzodiazepines and is indicated where general anesthesia has... [Pg.156]

Further new competitive AMPA antagonists include the imidazo-fused 23-benzodiazepine derivative 103. This compound showed excellent anticonvulsant activity and other activities indicative of possible therapeutic significance in human stroke and Parkinson k disease <00BMC2127>. An efficient synthesis of fluorine-containing H-1,4-diazepino[6,5-/t]quinolines has been described based on iV,/V-dimethyl-5,7-bis(trifluoroacetyl)-8-quinolylamine and an aromatic nucleophilic displacement with 1,2-ethylenediamine, followed by cyclocondensation <00S1822>. [Pg.360]

Diazepam and its nordiazepam, oxazepam, and temazepam metabolites are well retained by the MIP, while they are much less retained on NIP, also exhibiting large RSD. Other benzodiazepines of similar structures (Figure 1.50) were well retained on the MIP, showing that this template can be used for the general class of benzodiazepines. Two benzodiazepines studied, chlordiazepoxide and flunitrazepam, were poorly retained, indicating poor fit of these structures into the templated MIP. [Pg.60]
