Methadone benzodiazepines

In the same paper, these authors also observed that MEKC with surfactants in plain aqueous buffers failed to resolve the highly hydrophobic analytes (e.g., amphetamine, methamphetamine, methadone, benzodiazepines). Resolution of these compounds could be obtained by adding low percentages of acetonitrile (5-10%), thus bringing about MEKC conditions resembling those reported by Weinbeiger and Lurie (1991). [Pg.170]

Anxiety disorders are common in the population of opioid-addicted individuals however, treatment studies are lacking. It is uncertain whether the frequency of anxiety disorders contributes to high rates of illicit use of benzodiazepines, which is common in methadone maintenance programs (Ross and Darke 2000). Increased toxicity has been observed when benzodiazepines are co-administered with some opioids (Borron et al. 2002 Caplehorn and Drummer 2002). Although there is an interesting report of clonazepam maintenance treatment for methadone maintenance patients who abuse benzodiazepines, further studies are needed (Bleich et al. 2002). Unfortunately, buspirone, which has low abuse liability, was not effective in an anxiety treatment study in opioid-dependent subjects (McRae et al. 2004). Current clinical practice is to prescribe SSRIs or other antidepressants that have antianxiety actions for these patients. Carefully controlled benzodiazepine prescribing is advocated by some practitioners. [Pg.92]

A dramatically different pattern is found in surveys of drug abuse treatment facilities. Substance abuse treatment centers have reported that more than 20% of patients use benzodiazepines weekly or more frequently, with 30%— 90% of opioid abusers reporting illicit use (Iguchi et al. 1993 Stitzer et al 1981). Methadone clinics reported that high proportions ofurine samples are positive for benzodiazepines (Darke et al. 2003 Dinwiddle et al. 1996 Ross and Darke 2000 Seivewright 2001 Strain et al. 1991 Williams et al. 1996). The reasons for the high rates of benzodiazepine use in opioid addicts include self-medication of insomnia, anxiety, and withdrawal symptoms, as well as attempts to boost the euphoric effects of opioids. [Pg.117]

Sporadic use (e.g., for the induction of sleep after a psychostimulant binge) does not require specific detoxification. Sustained use can be treated as described in the previous sections on detoxification from therapeutic or high dosages but with added caution. In mixed opioid and benzodiazepine abuse, the patient should be stabilized with methadone (some clinicians use other oral preparations of opioids) and a benzodiazepine. Buprenorphine should not be administered with benzodiazepines, because a pharmacodynamic interaction is possible (Ibrahim et al. 2000 Kilicarslan and Sellers 2000) and fatalities have been reported with the combination (Reynaud et al. 1998). Sedative-hypnotic withdrawal is the more medically serious procedure, and we usually... [Pg.133]

Note Tertiary amines and quaternary ammonium compounds yield stronger colors than primary amines [25]. The dipping solution can also be used as spray solution [44]. Other reagent compositions have also been reported in the literature (1, 3, 6, 12, 13, 15, 18, 21, 23, 41] In some cases the reagents have been made up in acetone [38, 39], methanol [14] or ethanol [37] and/or acidified with hydrochloric acid [3, 33, 37-40]. The concentrations of hexachloroplatinic(IV) acid have been in the range of 0.05 -0.4 those of potassium iodide between 0.5 and 24spray solution containing 2% potassium iodide and 0.23170 hexachloroplatinic(IV) acid hexahydrate in N-hydro-chloric acid is reported to yield the best coloration results with respect to detection sensitivity and color differentiation in the detection of morphine, codeine, quinine, methadone and cocaine [46]. Acidic reagent solutions have been recommended for benzodiazepines [10, 11]. Sulfones do not react [39]. [Pg.188]
