NORPRAMIN® (Desipramine Hydrochloride Tablets USP)
NORPRAMIN® (desipramine hydrochloride tablets USP) 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 NORPRAMIN 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 of the need for close observation and communication with the prescriber. NORPRAMIN is not approved for use in pediatric patients. (See WARNINGS: Clinical Worsening and Suicide Risk, PRECAUTIONS: Information for Patients, and PRECAUTIONS: Pediatric Use.) DESCRIPTION NORPRAMIN® (desipramine hydrochloride USP) is an antidepressant drug of the tricyclic type, and is chemically: 5H-Dibenz[bƒ]azepine-5-propanamine,10,11-dihydro-N-methyl-, monohydrochloride. 1 Reference ID: 3536021 Inactive Ingredients The following inactive ingredients are contained in all dosage strengths: acacia, calcium carbonate, corn starch, D&C Red No. 30 and D&C Yellow No. 10 (except 10 mg and 150 mg), FD&C Blue No. 1 (except 25 mg, 75 mg, and 100 mg), hydrogenated soy oil, iron oxide, light mineral oil, magnesium stearate, mannitol, polyethylene glycol 8000, pregelatinized corn starch, sodium benzoate (except 150 mg), sucrose, talc, titanium dioxide, and other ingredients. -

Published OnlineFirst September 26, 2013; DOI: 10.1158/2159-8290.CD-13-0183 ABSTRACT Small cell lung cancer (SCLC) is an aggressive neuroendocrine subtype of lung cancer with high mortality. We used a systematic drug repositioning bioinformat- ics approach querying a large compendium of gene expression profi les to identify candidate U.S. Food and Drug Administration (FDA)–approved drugs to treat SCLC. We found that tricyclic antidepressants and related molecules potently induce apoptosis in both chemonaïve and chemoresistant SCLC cells in culture, in mouse and human SCLC tumors transplanted into immunocompromised mice, and in endog- enous tumors from a mouse model for human SCLC. The candidate drugs activate stress pathways and induce cell death in SCLC cells, at least in part by disrupting autocrine survival signals involving neurotransmitters and their G protein–coupled receptors. The candidate drugs inhibit the growth of other neuroendocrine tumors, including pancreatic neuroendocrine tumors and Merkel cell carcinoma. -

Sayem Alam,† Goutam Ghosh,‡ and Kabir-ud-Din*,† Department of Chemistry, Aligarh Muslim UniVersity, Aligarh-202 002, India, and UGC-DAE Consortium for Scientific Research, Trombay, Mumbai- 400 085, India ReceiVed: May 13, 2008; ReVised Manuscript ReceiVed: August 1, 2008 Two amphiphilic drugs, promethazine hydrochloride (PMT) and imipramine hydrochloride (IMP), have been studied using both static and dynamic light scattering techniques. Due to having rigid tricyclic hydrophobic moieties in their molecules, these drugs show interesting association behavior. The static light scattering (SLS) measurements show that the self-association commenced above a well-defined critical micellar concentration (cmc), which decreases with increasing NaBr concentration. The Gibbs energy of micellization, 0 ∆GM, in all cases, is negative. The colloidal stability of the system in terms of the interparticle interaction at different NaBr concentrations was studied using the dynamic light scattering (DLS) technique. The experimentally evaluated interparticle interaction parameter (kD) was compared with the Derjaguin-Landau- Verwey-Overbeek (DLVO) model. Interestingly, these two drugs with similar molecular structure show difference in their interparticle interactions, e.g., PMT showed complete agreement with the DLVO model whereas IMP showed clear deviation from this model at lower concentrations and agreement at higher concentrations of NaBr. 1.

Hugo De Cuyper (18.1.1946 - 13.9.1994) Introduction Selective Serotonin Reuptake Inhibitors (SSRIs : fluvoxamine -Floxyfral® or Fevarin®-, fluoxetine -Prozac®-, sertraline - Serlain® or Zoloft®-, paroxetine -Seroxat® or Paxil®- and citalopram -Cipramil®-) are potent and competitive inhibitors of the high affinity neuronal re-uptake mechanism for serotonin. These drugs also inhibit the re-uptake of noradrenaline and, generally to a lesser extent, dopamine, at higher concentrations. Paroxetine is the most potent serotonin uptake inhibitor in vitro of the drugs investigated, and citalopram is the most selective inhibitor of serotonin re-uptake, with paroxetine being more selective than fluoxetine, fluvoxamine and sertraline. Of the drugs investigated, only sertraline is a more potent inhibitor of dopamine compared with noradrenaline uptake. SSRIs are not only as effective as the tricyclic antidepressants in the treatment of major depression but are also effective in the treatment of obsessive-compulsive disorder, panic disorder, eating disorders and premenstrual syndrome (1). Although the latency of onset to therapeutic response seems to be somewhat longer, most psychiatrists consider SSRIs the initital drug of choice in the treatment of depressive disorders. Indeed, these drugs are usually better tolerated since they do not produce muscarinic, histaminic and alpha adrenergic side effects. -

Department of Mental Health Parameters 3.8 for Use of Psychotropic Medication in Children and Adolescents
DEPARTMENT OF MENTAL HEALTH PARAMETERS 3.8 FOR USE OF PSYCHOTROPIC MEDICATION IN CHILDREN AND ADOLESCENTS Treatment provided outside the parametric elements in this guide requires special justification or consultation and subsequent documentation in medical record. December 19, 2018 INTRODUCTION The parametric elements of this guide are the dose range and dosage schedule. Doses are expressed by range, and titration to clinical efficacy, and are not specifically calibrated or adjusted for children whose ability to metabolize and excrete these drugs may be compromised. A discussion of metabolic variations largely due to the ethnic/racial/genetic background is beyond the scope of this document. Furthermore, dosing parameters are not expressed by body surface area or in weight adjusted doses. DMH Parameters 3.8 For Use of Psychotropic Medication for Children and Adolescents, is designed for the use of psychoactive medications for the treatment of diagnosed mental disorders (not exclusively behavioral problems) in children and adolescents, up to 18 years of age, who receive treatment by either directly-operated Los Angeles County Department of Mental Health clinics or the Department’s contracted agencies. The use of psychotropic agents in early childhood is relatively infrequent; the use of such agents in children under the age of three is rare. (A companion set of parameters regarding the use of psychotropic medications for the treatment of mental disorders is available at http://dmh.lacounty.gov/wps/portal/dmh/clinical_tools/clinical_practice and should be used in conjunction with these parameters.) The intent of this document is to provide a framework for quality management relating to the major classes of psychoactive medications used in children and adolescents. -
Imipramine Hydrochloride Tablets USP 10 Mg, 25 Mg, and 50 Mg
IMIPRAMINE HYDROCHLORIDE - imipramine hydrochloride tablet, film coated Excellium Pharmaceutical, Inc Rx only Prescribing Information 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 Imipramine Hydrochloride 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 of the need for close observation and communication with the prescriber. Imipramine Hydrochloride is not approved for use in pediatric patients (see WARNINGS: Clinical Worsening and Suicide Risk, PRECAUTIONS: Information for Patients, and PRECAUTIONS: Pediatric Use).

II.3.3 Tricyclic and Tetracyclic Antidepressants by Akira Namera and Mikio Yashiki
3.3 II.3.3 Tricyclic and tetracyclic antidepressants by Akira Namera and Mikio Yashiki Introduction Many of antidepressants exert their eff ects by inhibiting the reuptake of norepinephrine and serotonin and by accerelating the release of them at synaptic terminals of neurons in the brain. As characteristic structures of such drugs showing antidepressive eff ects, many of them have tricyclic or tetracyclic nuclei; this is the reason why they are called “ tricyclic antidepressants or tetracyclic antidepressants”. Th ere are many cases of suicides using the antidepressants; their massive intake sometimes causes death. About 10 kinds of tricyclic and tetracyclic antidepressants are now being used in Japan (> Figure 3.1); among them, amitriptyline is best distributed [1, 2]. Recently, the use of tetracyclic antidepressants is increasing, because of their mild side eff ects and their high eff ectiveness with their small doses; the increase of their use is causing the increase of their poisoning cases. Although carbamazepine does not belong to the antidepressant group, its structure is very similar to those of tricyclic antidepressants; therefore, the drug is also in- cluded in this chapter. GC/MS analysis Reagents and their preparation • Amitriptyline, carbamazepine, clomipramine, desipramine, imipramine, maprotiline, mi- anserin, nortriptyline and trimipramine can be purchased from Sigma (St. Louis, MO, USA); pure powder of the following drugs was donated by each manufacturer: amoxapine by Takeda Chem.

Dosulepin (Prothiaden®): Guidance on Withdrawal
Dosulepin (Prothiaden®): Guidance on withdrawal Indication: Dosulpein is a tricyclic antidepressant (TCA) indicated in the treatment of depressive i illness, especially where sedation is required. Formulary status: Non formulary (but some patients may have been initiated and maintained historically). Note: When an antidepressant is to be prescribed, TCAs are no longer considered first line treatment for depression due to their side effect profile. SSRIs are equally effective as other antidepressants ii and have a favourable risk-benefit ratio. Dosulepin is effective but known to be particularly dangerous in overdose and now not recommended for treatment of depression. Dose: In the treatment of depression, the usual initial dose is 75 mg daily in divided doses or as a single dose at bedtime, increased if necessary to 150 daily. Doses can be increased gradually up to 225mg daily in some circumstances (e.g. hospital use). The recommended initial dose for the elderly in the UK is 50-75 mg daily which should be increased with caution under close supervision. Unlicensed uses: Neuropathic pain/chronic pain, insomnia, anxiety. Mode of action: Serotonin and noradrenaline reuptake inhibitor. Anticholinergic activity may cause dry mouth, constipation and blurred vision. H1 blockade may cause sedation. Adrenergic αlpha 1 receptor blockade may cause dizziness, sedation and hypotension. iii Ion channel blockade may cause cardiac arrhythmias and seizures especially in overdose. Reasons for caution: Reports of cardiac arrhythmias, QTc prolongation, sinus tachycardia orthostatic hypotension. Drug interactions. High rate of fatality in overdose. Side effects: As listed above Guidance and recommendations: No new patients should be prescribed dosulepin. Patients currently prescribed dosulepin should be identified and have their treatment history reviewed. -
