  • Coadministration of Intramuscular Olanzapine and Benzodiazepines in Agitated Patients with Mental Illness
    ORIGINAL RESEARCH Open Access Coadministration of intramuscular olanzapine and benzodiazepines in agitated patients with mental illness Andrew M. Williams, PharmD, BCPP, BCGP1 How to cite: Williams AM. Coadministration of intramuscular olanzapine and benzodiazepines in agitated patients with mental illness. Ment Health Clin [Internet].

Abstract Introduction: Intramuscular antipsychotics are commonly used to manage agitated patients. In 2005, Eli Lilly placed a warning on olanzapine’s prescribing information following post-marketing reports of fatal drug reactions when intramuscular olanzapine was used in the setting of benzodiazepines. Data is lacking examining this drug combination. Methods: A medication use evaluation was conducted at a county psychiatric hospital surveying the usage of concomitant intramuscular olanzapine and lorazepam from October 1, 2016, to July 20, 2017. A literature search was conducted to review available evidence. Results: Ninety-one instances of the drug combination were discovered, with no serious adverse events following administration. Of these 91 patients, 41 received both medications within 60 minutes of each other. No instances of hypotension, bradycardia, bradypnea, or oxygen desaturation occurred following administration. The literature review yielded 1 randomized, placebo-controlled clinical trial, 3 retrospective chart reviews, and several case studies. Discussion: Data detailing a causal relationship between olanzapine/benzodiazepine combinations and serious adverse effects is lacking. Available evidence does not consistently support a strong cause and effect relationship. The results of this medication use evaluation are not consistent with the Food and Drug Administration warning.

Monforte, Ph.D., DABFT, ToxTalk Editor 4: Safety Of Buprenorphine: Ceiling For Cardio-Respiratory And Subjective Effects At High IV Doses Marilyn A. Huestis, Annie Umbricht, Kenzie L. Preston, and Edward J. Cone, NIDA Intramural Research Program, 5500 Nathan Shock Dr., Baltimore, MD 21224. Buprenorphine (BUP), a partial 11 agonist and K antagonist, is under development for treatment of opioid dependence. The present study was conducted to test the safety and abuse potential of intravenous (IV) BUP in the range of doses used for maintenance treatment. Concerns have been raised about the potential acute health risk ofbuprenorphine if diverted and used by the IV route at doses equivalent to those used for maintenance. Subjective effects ofBUP SL (12 mg) and IV/SL placebo (in random order) and BUP IV (2, 4, 8, 12, and 16 mg in increasing dose order) were evaluated in separate sessions in this single-blind, double-dummy study. Data were collected from 6 non-dependent male opioid abusers. Safety parameters included continuous monitoring of vital signs and oxygen saturation for 3 h after drug administration and additional collections over the next 72 h. Subjective measures included visual analog scales of global drug effects, ARCI subscales, and adjective rating scales. An increase in Systolic Blood Pressure for the 8 mg IV dose (+ 13.5 mm Hg) as .~\ compared to placebo was the only statistically significant change in blood pressure, heart rate or oxygen saturation among the 7 drug conditions.

  • Computer-Assisted Synthetic Analysis. a Rapid Computer Method for the Semiquantitative Assignment of Conformation of Six-Membered Ring Systems
    J. Org. Chem. 1980,45, 765-780 765 Computer-Assisted Synthetic Analysis. A Rapid Computer Method for the Semiquantitative Assignment of Conformation of Six-Membered Ring Systems. 2. Assessment of Conformational Energies E. J. Corey* and N. Frank Feiner Department of Chemistry, Harvard University, Cambridge, Massachusetts 02138 Received May 23, 1979 The description of a new semiquantitative computer-based method to be used in synthetic planning for the prediction of the conformation of six-membered ring systems is carried on in this paper through the final stages of assignment. Starting with specific geometries from preliminary assignment (i.e., chair, half-chair, boat) which are deduced from the first stage of analysis, simple empirical procedures are applied to calculate approximate conformational destablization energies of each of the preliminary (i.e.,tentative) geometries. These procedures are based upon consideration of the disposition of axial and equatorial appendages and do not rely on three- dimensional atomic coordinates. The quantification of interatomic interactions depends on seta of appendage interaction values, the derivation of which is described. Rules for identifying destabilizing interactions between appendages within the same ring and on adjoining rings are given. The destabilization energies so obtained lead to the final conformational decision. Comparisons are made between the results of the present method and those obtained both by more complex molecular mechanics calculations and by X-ray crystallographic analysis. The importance of stereochemical factors in the analysis of complex synthetic problems cannot be exaggerated. In the accompanying paper’ we have outlined the plan of development of such an aspect of the Harvard LHASA computer program for synthetic analysis and have dis- 9 cussed the initial steps for predicting conformations of 8 10 six-membered ring systems.

  • Neurological Disease
    Neurological Disease A range of neurological disorders, including epilepsy and dystonia, may involve dysfunctional intracortical inhibition, and may respond to treatments that modify it. Parkinson’s is a neurodegenerative disease characterized by increased activity of GABA in basal ganglia and the loss of dopamine in nigrostriatum, associated with rigidity, resting tremor, gait with accelerating steps, and fixed inexpressive face. Neurological deficits, along with neuromuscular involvement, are characteristic of mitochondrial disease, and these symptoms can have a dramatic impact on patient quality of life. Neurological features may be manifold, ranging from neural deafness, ataxia, peripheral neuropathy, migraine, seizures, strokelike episodes and dementia and depend on the part of the nervous system affected. www.MedChemExpress.com 1 Neurological Disease Inhibitors & Modulators (+)-Cevimeline hydrochloride hemihydrate (+)-Dihydrexidine hydrochloride Cat.
