(*Sedative/hypnotic benzodiazepines are included in Sedative/Hypnotics criteria.) 1 1 Dosage 1.1 Adults Non-sedative/hypnotic benzodiazepines are FDA-approved for use in the outpatient setting to manage anxiety (alprazolam, chlordiazepoxide, clorazepate, oral diazepam, lorazepam, oxazepam), panic disorder (alprazolam, clonazepam), acute musculoskeletal (MS) conditions including spasticity (oral diazepam), seizures [clobazam (Lennox-Gastaut syndrome), clonazepam, clorazepate, nasal, oral and rectal diazepam], and acute alcohol withdrawal (chlordiazepoxide, clorazepate, oral diazepam, oxazepam).[1-10] The FDA has approved a new dosage formulation for clobazam, an oral film (Sympazan®), for adjunctive seizure management in Lennox-Gastaut syndrome.[11] A new diazepam nasal formulation (Valtoco®) has been FDA-approved for use in adult patients to treat intermittent frequent seizure episodes that differ from a patient’s usual seizure pattern.[12] The chlordiazepoxide-amitriptyline combination is indicated for depression with associated anxiety symptoms, while chlordiazepoxide/clidinium is FDA-approved for emotional factor control in gastrointestinal disorders as well as adjunctive use in peptic ulcer disease and irritable bowel syndrome.[13, 14] Tables 1 and 2 summarize the adult maximum recommended dosages for non-sedative/hypnotic benzodiazepines as monotherapy and combination therapy.

  • XANAX® Alprazolam Tablets, USP
    XANAX® alprazolam tablets, USP CIV WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death [see Warnings, Drug Interactions]. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation. DESCRIPTION XANAX Tablets contain alprazolam which is a triazolo analog of the 1,4 benzodiazepine class of central nervous system-active compounds. The chemical name of alprazolam is 8-Chloro-1-methyl-6-phenyl-4H-s-triazolo [4,3-α] [1,4] benzodiazepine. The structural formula is represented to the right: Alprazolam is a white crystalline powder, which is soluble in methanol or ethanol but which has no appreciable solubility in water at physiological pH. Each XANAX Tablet, for oral administration, contains 0.25, 0.5, 1 or 2 mg of alprazolam. XANAX Tablets, 2 mg, are multi-scored and may be divided as shown below: 1 Reference ID: 4029640 Inactive ingredients: Cellulose, corn starch, docusate sodium, lactose, magnesium stearate, silicon dioxide and sodium benzoate. In addition, the 0.5 mg tablet contains FD&C Yellow No. 6 and the 1 mg tablet contains FD&C Blue No. 2. CLINICAL PHARMACOLOGY Pharmacodynamics CNS agents of the 1,4 benzodiazepine class presumably exert their effects by binding at stereo specific receptors at several sites within the central nervous system. Their exact mechanism of action is unknown. Clinically, all benzodiazepines cause a dose-related central nervous system depressant activity varying from mild impairment of task performance to hypnosis.

  • Calculating Equivalent Doses of Oral Benzodiazepines
    Calculating equivalent doses of oral benzodiazepines Background Benzodiazepines are the most commonly used anxiolytics and hypnotics (1). There are major differences in potency between different benzodiazepines and this difference in potency is important when switching from one benzodiazepine to another (2). Benzodiazepines also differ markedly in the speed in which they are metabolised and eliminated. With repeated daily dosing accumulation occurs and high concentrations can build up in the body (mainly in fatty tissues) (2). The degree of sedation that they induce also varies, making it difficult to determine exact equivalents (3). Answer Advice on benzodiazepine conversion NB: Before using Table 1, read the notes below and the Limitations statement at the end of this document. Switching benzodiazepines may be advantageous for a variety of reasons, e.g. to a drug with a different half-life pre-discontinuation (4) or in the event of non-availability of a specific benzodiazepine. With relatively short-acting benzodiazepines such as alprazolam and lorazepam, it is not possible to achieve a smooth decline in blood and tissue concentrations during benzodiazepine withdrawal. These drugs are eliminated fairly rapidly with the result that concentrations fluctuate with peaks and troughs between each dose. It is necessary to take the tablets several times a day and many people experience a "mini-withdrawal", sometimes a craving, between each dose. For people withdrawing from these potent, short-acting drugs it has been advised that they switch to an equivalent dose of a benzodiazepine with a long half life such as diazepam (5). Diazepam is available as 2mg tablets which can be halved to give 1mg doses.

  • Drugs of Abuse: Benzodiazepines
    Drugs of Abuse: Benzodiazepines What are Benzodiazepines? Benzodiazepines are central nervous system depressants that produce sedation, induce sleep, relieve anxiety and muscle spasms, and prevent seizures. What is their origin? Benzodiazepines are only legally available through prescription. Many abusers maintain their drug supply by getting prescriptions from several doctors, forging prescriptions, or buying them illicitly. Alprazolam and diazepam are the two most frequently encountered benzodiazepines on the illicit market. Benzodiazepines are What are common street names? depressants legally available Common street names include Benzos and Downers. through prescription.

  • The Emergence of New Psychoactive Substance (NPS) Benzodiazepines
    Issue: Ir Med J; Vol 112; No. 7; P970 The Emergence of New Psychoactive Substance (NPS) Benzodiazepines. A Survey of their Prevalence in Opioid Substitution Patients using LC-MS S. Mc Namara, S. Stokes, J. Nolan HSE National Drug Treatment Centre Abstract Benzodiazepines have a wide range of clinical uses being among the most commonly prescribed medicines globally. The EU Early Warning System on new psychoactive substances (NPS) has over recent years detected new illicit benzodiazepines in Europe’s drug market1. Additional reference standards were obtained and a multi-residue LC- MS method was developed to test for 31 benzodiazepines or metabolites in urine including some new benzodiazepines which have been classified as New Psychoactive Substances (NPS) which comprise a range of substances, including synthetic cannabinoids, opioids, cathinones and benzodiazepines not covered by international drug controls. 200 urine samples from patients attending the HSE National Drug Treatment Centre (NDTC) who are monitored on a regular basis for drug and alcohol use and which tested positive for benzodiazepine class drugs by immunoassay screening were subjected to confirmatory analysis to determine what Benzodiazepine drugs were present and to see if etizolam or other new benzodiazepines are being used in the addiction population currently. Benzodiazepine prescription and use is common in the addiction population. Of significance we found evidence of consumption of an illicit new psychoactive benzodiazepine, Etizolam. Introduction Benzodiazepines are useful in the short-term treatment of anxiety and insomnia, and in managing alcohol withdrawal. 1 According to the EMCDDA report on the misuse of benzodiazepines among high-risk opioid users in Europe1, benzodiazepines, especially when injected, can prolong the intensity and duration of opioid effects.
