Effects of Chronic Administration of Sibutramine on Body Weight, Food
Exp. Anim. 49(4), 239–249, 2000 Effects of Chronic Administration of Sibutramine on Body Weight, Food Intake and Motor Activity in Neonatally Monosodium Glutamate-Treated Obese Female Rats: Relationship of Antiobesity Effect with Monoamines Terutake NAKAGAWA1), Kiyoharu UKAI1), Tadashi OHYAMA1), Yutaka GOMITA2), and Hitoshi OKAMURA3) 1)Central Research Institute, Kaken Pharmaceutical Co.

Treatment with sibutramine at 3 and 10 mg/kg p.o. once a day continuously for 14 days improved these parameters, and the degree of improvement was dose related. The plasma lipid values in MSG-OB rats, which were the same as those in normal rats, were decreased by consecutive administration of sibutramine. Levels of hypothalamic monoamines (MAs) such as norepinephrine, 5-HT (serotonin) and dopamine and their metabolites DOPAC, HVA and 5- HIAA were decreased in MSG-OB rats, and further decrease in them, though slight, was observed with consecutive daily administration of sibutramine, probably as a result of the feedback attributable to an increase in MA in synapses caused by inhibition of MA uptake by sibutramine. -
Insights Into the Mechanisms of Action Ofthe MAO Inhibitors Phenelzine and Tranylcypromine
Insights into the Mechanisms of Action of the MAO Inhibitors Phenelzine and Tranylcypromine: A Review Glen B. Baker, Ph.D., Ronald T. Coutts, Ph.D., D.Sc., Kevin F. McKenna, M.D., and Rhonda L. Sherry-McKenna, B.Sc. Neurochemical Research Unit, Department of Psychiatry and Faculty of Pharmacy and Pharmaceutical Sciences, University of Alberta, Edmonton, Alberta Submitted: July 10, 1992 Accepted: October 7, 1992 Although the non-selective monoamine oxidase inhibitors phenelzine and tranylcypromine have been used for many years, much still remains to be understood about their mechanisms of action. Other factors, in addition to the inhibition of monoamine oxidase and the subsequent elevation of brain levels of the catecholamines and 5-hydroxytryptamine, may contribute to the overall pharma- cological profiles ofthese drugs. This review also considers the effects on brain levels of amino acids and trace amines, uptake and release of neurotransmitter amines at nerve terminals, receptors for amino acids and amines, and enzymes other than monoamine oxidase, including enzymes involved in metabolism of other drugs. The possible contributions of metabolism and stereochemistry to the actions of these monoamine oxidase inhibitors are discussed. Key Words: amino acids, monoamine oxidase, neurotransmitter amines, phenelzine, tranylcypromine, uptake Despite the fact that the non-selective monoamine oxidase nerve endings (Baker et al 1977; Raiteri et al 1977) and/or (MAO) inhibitors phenelzine (PLZ) and tranylcypromine may act as neuromodulators through direct actions on recep- (TCP) (see Fig. 1) have been used clinically for many years, tors for the catecholamines and/or 5-HT (Jones 1983; much remains to be learned about theirmechanisms ofaction. -

A Review of Serotonin Toxicity Data: Implications for the Mechanisms of Antidepressant Drug Action P
ARTICLE IN PRESS REVIEW A Review of Serotonin Toxicity Data: Implications for the Mechanisms of Antidepressant Drug Action P. Ken Gillman Data now exist from which an accurate definition for serotonin toxicity (ST), or serotonin syndrome, has been developed; this has also lead to precise, validated decision rules for diagnosis. The spectrum concept formulates ST as a continuum of serotonergic effects, mediated by the degree of elevation of intrasynaptic serotonin. This progresses from side effects through to toxicity; the concept emphasizes that it is a form of poisoning, not an idiosyncratic reaction. Observations of the degree of ST precipitated by overdoses of different classes of drugs can elucidate mechanisms and potency of drug actions. There is now sufficient pharmacological data on some drugs to enable a prediction of which ones will be at risk of precipitating ST, either by themselves or in combinations with other drugs. This indicates that some antidepressant drugs, presently thought to have serotonergic effects in animals, do not exhibit such effects in humans. Mirtazapine is unable to precipitate serotonin toxicity in overdose or to cause serotonin toxicity when mixed with monoamine oxidase inhibitors, and moclobemide is unable to precipitate serotonin toxicity in overdose. Tricyclic antidepressants (other than clomipramine and imipramine) do not precipitate serotonin toxicity and might not elevate serotonin or have a dual action, as has been assumed. Key Words: Serotonin toxicity, monoamine oxidase inhibitors, se- do not, and cannot, cause ST (Gillman 2003c; Isbister and Whyte lective serotonin reuptake inhibitors, tricyclic antidepressants, mir- 2003). Such erroneous reports are still being published in tazapine, moclobemide prominent journals (Haddow et al 2004) and continue to main- tain the confused and inaccurate understanding of this toxidrome (Gillman 2005b; Isbister and Buckley 2005). -

Phenelzine Switching Advice 11 May 2020
Mental Health Special Interest Group Guidance for switching from phenelzine to another antidepressant The supplier of phenelzine sulphate tablets has notified PHARMAC that they can no longer supply this medication in New Zealand. This is reportedly a global issue so the supplier can no longer guarantee supply of any brand of phenelzine. Supplies of phenelzine tablets are likely to run out by mid-late May 2020. People taking phenelzine should be reviewed and, if appropriate, transitioned to another antidepressant as soon as possible. Phenelzine is a non-selective and irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine class. The only remaining non-selective irreversible MAOI available in New Zealand is tranylcypromine. Tranylcypromine is a non-hydrazine MAOI and differs significantly from phenelzine in some aspects, as outlined below. Tranylcypromine may be an appropriate alternative antidepressant for some patients ; however, it is important to consider an individual’s physical health and psychiatric history, and whether an MAOI is still appropriate. General practitioners should consult with a psychiatrist regarding treatment options and transition. Reducing and stopping phenelzine The dose of phenelzine should ideally be tapered down over a minimum of four weeks, starting immediately in light of very limited supplies. We acknowledge that a faster taper may be required in some cases due to rapidly declining stock. Irreversible MAOIs are associated with a high risk of discontinuation symptoms, e.g. nightmares, headache, irritability, feeling cold, disorientation, hypomania, nausea, sweating, palpitations, myoclonic jerks and, rarely, catatonia or psychosis. Significant discontinuation symptoms should be closely monitored and managed in consultation with a psychiatrist. It is important to maintain MAOI dietary and co-prescribed medication precautions for at least 14 days after stopping phenelzine. -
Emsam (Selegiline Transdermal System) Continuous Delivery for Once-Daily Application
® EMSAM (SELEGILINE TRANSDERMAL SYSTEM) CONTINUOUS DELIVERY FOR ONCE-DAILY APPLICATION Rx only Suicidality and Antidepressant Drugs Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of EMSAM or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised for the need for close observation and communication with the prescriber. EMSAM is not approved for use in pediatric patients. (See WARNINGS: Clinical Worsening and Suicide Risk, PRECAUTIONS: Information for Patients, and PRECAUTIONS: Pediatric Use) DESCRIPTION EMSAM® (selegiline transdermal system) is a transdermally administered antidepressant. When applied to intact skin, EMSAM is designed to continuously deliver selegiline over a 24-hour period. Selegiline base is a colorless to yellow liquid, chemically described as (-)-(N)-Methyl-N-[(1R)-1-methyl-2-phenylethyl]prop-2-yn-1-amine. It has an empirical formula of C13H17N and a molecular weight of 187.30.
