Analysis of a Benzodiazepine-Based Drug Using GC-MS 28
LAAN-E-MS-E028 GCMS Gas Chromatograph Mass Spectrometer Analysis of a Benzodiazepine-Based Drug Using GC-MS 28 Benzodiazepine drugs are commonly used in sleeping aids and tranquilizers, and sometimes in crimes or suicide. Therefore, these chemical substances are often analyzed by forensic laboratories for criminal or academic investigations.

Medications in Long-Term Care: When Less Is More
Medications in Long-Term Care: When Less is More a, b,c Thomas W. Meeks, MD *, John W. Culberson, MD , d,e Monica S. Horton, MD, MSc KEYWORDS Long-term care Inappropriate prescribing Polypharmacy Psychotropics Opiates Sedatives HISTORY OF MEDICATION REDUCTION IN LONG-TERM CARE The Nursing Home Reform Act (OBRA-87) enacted in 1987 called for sweeping changes in the standards of care in nursing homes in accordance with new, more demanding federal regulations. For example, OBRA-87 called for a new approach to the use of antipsychotics in persons with dementia. Because antipsychotics were regarded as frequently inappropriate chemical restraints in long-term care (LTC), OBRA-87 mandated dose reductions in antipsychotics in an effort to discontinue them whenever possible. OBRA-87 proposed that a safer, more supportive environ- ment in LTC settings would facilitate such reductions in antipsychotic doses.1 Overall rates of potentially inappropriate prescribing in older adults have ranged from 12% to 40%, depending on the setting, criteria, and population sampled.2 Devel- oping from burgeoning concerns for polypharmacy and potential iatrogenic toxicity of medication in older adults, expert consensus lists of potentially inappropriate pharma- cotherapy in the elderly (PIPE) began to emerge. In general, drugs with activity in the central nervous system (CNS) were commonly placed on these PIPE lists, and hence our focus on such medications in this review. This work was supported by the following Geriatric Academic Career Awards: (1) K01 HP00047-02 (Dr. Meeks) (2) K01 HP00080-02 (Dr. Culberson) (3) K01 HP00114-02 (Dr. Horton).

Cyclobenzaprine enhance psychoactive effects. Individuals have may enhance the effects of other CNS depressants reported taking cyclobenzadrine both orally and including alcohol, barbiturates, benzodiazepines intra-nasally at doses ranging from 10 mg to 60 mg. and narcotics and anecdotal reports indicate it is Sedation, relaxation and increased heart rate were used non-medically to induce euphoria and the most common effects reported. Euphoria was relaxation. reported by a smaller number of individuals. Licit Uses: Illicit Distribution: Cyclobenzaprine hydrochloride is approved for Several indicators suggest that cyclobenzaprine use in the United States as a muscle relaxant. It is is being intentionally misused or abused. According marketed under the brand names Flexeril® and to the American Association of Poison Control Amrix® and as generic formulations in 5, 7.5, and 10 Centers, 10,615 case mentions and 4,444 single mg tablets intended for short-term (2 to 3 week) oral exposures were associated with cyclobenzaprine in administration. The usual starting dose is 5 mg, 2016, resulting in 75 major medical outcomes and three times per day. The maximum recommended four deaths among single substance exposures.
