INTRODUCTION Based on the review of the data on quality, safety and efficacy, the application for IPRABRONCH 250 Mikrogramm/ml Lösung für einen Vernebler, indicated in Bronchospasm associated with chronic obstructive pulmonary disease (COPD) Airways obstruction in patients with acute and chronic asthma, when used concomitantly with inhaled β 2 agonists, is approved. After changing the RMS, Germany is the new RMS. The former procedure number was UK/H/3401/001/DC. This application was submitted using Decentralised procedure, with UK as Reference Member State (RMS) and Austria (AT) and Germany (DE) as Concerned Stated (CMS). The application was submitted under Article 10.3 of Directive 2001/83/EC, as amended, as a hybrid application. The reference medicinal product for this application is Atrovent 250 UDVs. 1 ml and Atrovent UDVs, 2 ml (Boehringer Ingelheim Limited, UK) which was first authorised in the UK on 27 August 1986. Ipratropium bromide is a non-selective antagonist of the muscarine receptors M1, M2, M3, M4 and M5. Although ipratropium bromide blocks all five muscarinic receptor subtypes with similar affinity, it is likely that M3-receptor antagonism alone for the bronchodilating effect. However, the blockade of the M2-receptor subtype allows further release of presynaptic acetylcholine and may antagonise the bronchodilatory effect of blocking the M3-receptor. No new non-clinical or clinical data have been submitted, which is acceptable given that this is a hybrid application based on an originator product that has been on clinical use for over 10 years. The RMS has been assured that acceptable standards of Good Manufacturing Practice (GMP) are in place at all sites responsible for the manufacturer, assembly and batch release of this product. For manufacturing sites within the community, the RMS has accepted copies of current manufacturer authorisations issued by inspection services of the competent authorities as certificate that acceptable standards of GMP are in place at those sites. The RMS and CMS considered that the application could be approved at the end of procedure (Day 210) on 08 March 2011. After a subsequent national phase, a licence was granted in the UK on 26 October 2011. II.

  • Muscarinic Acetylcholine Receptor
    mAChR Muscarinic acetylcholine receptor mAChRs (muscarinic acetylcholine receptors) are acetylcholine receptors that form G protein-receptor complexes in the cell membranes of certainneurons and other cells. They play several roles, including acting as the main end-receptor stimulated by acetylcholine released from postganglionic fibersin the parasympathetic nervous system. mAChRs are named as such because they are more sensitive to muscarine than to nicotine. Their counterparts are nicotinic acetylcholine receptors (nAChRs), receptor ion channels that are also important in the autonomic nervous system. Many drugs and other substances (for example pilocarpineand scopolamine) manipulate these two distinct receptors by acting as selective agonists or antagonists. Acetylcholine (ACh) is a neurotransmitter found extensively in the brain and the autonomic ganglia. www.MedChemExpress.com 1 mAChR Inhibitors & Modulators (+)-Cevimeline hydrochloride hemihydrate (-)-Cevimeline hydrochloride hemihydrate Cat.

  • Amanita Muscaria (Fly Agaric)
    J R Coll Physicians Edinb 2018; 48: 85–91 | doi: 10.4997/JRCPE.2018.119 PAPER Amanita muscaria (fly agaric): from a shamanistic hallucinogen to the search for acetylcholine HistoryMR Lee1, E Dukan2, I Milne3 & Humanities The mushroom Amanita muscaria (fly agaric) is widely distributed Correspondence to: throughout continental Europe and the UK. Its common name suggests MR Lee Abstract that it had been used to kill flies, until superseded by arsenic. The bioactive 112 Polwarth Terrace compounds occurring in the mushroom remained a mystery for long Merchiston periods of time, but eventually four hallucinogens were isolated from the Edinburgh EH11 1NN fungus: muscarine, muscimol, muscazone and ibotenic acid. UK The shamans of Eastern Siberia used the mushroom as an inebriant and a hallucinogen. In 1912, Henry Dale suggested that muscarine (or a closely related substance) was the transmitter at the parasympathetic nerve endings, where it would produce lacrimation, salivation, sweating, bronchoconstriction and increased intestinal motility. He and Otto Loewi eventually isolated the transmitter and showed that it was not muscarine but acetylcholine. The receptor is now known variously as cholinergic or muscarinic. From this basic knowledge, drugs such as pilocarpine (cholinergic) and ipratropium (anticholinergic) have been shown to be of value in glaucoma and diseases of the lungs, respectively. Keywords acetylcholine, atropine, choline, Dale, hyoscine, ipratropium, Loewi, muscarine, pilocarpine, physostigmine Declaration of interests No conflicts of interest declared Introduction recorded by the Swedish-American ethnologist Waldemar Jochelson, who lived with the tribes in the early part of the Amanita muscaria is probably the most easily recognised 20th century. His version of the tale reads as follows: mushroom in the British Isles with its scarlet cap spotted 1 with conical white fl eecy scales.

Academic Editor: Patricia Valentao Received: 24 October 2014 / Accepted: 26 November 2014 / Published: 29 January 2015 Abstract: The plant indole alkaloid ibogaine has shown promising anti-addictive properties in animal studies. Ibogaine is also anti-addictive in humans as the drug alleviates drug craving and impedes relapse of drug use. Although not licensed as therapeutic drug and despite safety concerns, ibogaine is currently used as an anti-addiction medication in alternative medicine in dozens of clinics worldwide. In recent years, alarming reports of life-threatening complications and sudden death cases, temporally associated with the administration of ibogaine, have been accumulating. These adverse reactions were hypothesised to be associated with ibogaine’s propensity to induce cardiac arrhythmias. The aim of this review is to recapitulate the current knowledge about ibogaine’s effects on the heart and the cardiovascular system, and to assess the cardiac risks associated with the use of this drug in anti- addiction therapy. The actions of 18-methoxycoronaridine (18-MC), a less toxic ibogaine congener with anti-addictive properties, are also considered.

This paper endeavors to cover a wide variety of “legal highs,” IL, USA or uncontrolled psychoactive substances that may have abuse potential and may result in seri- ous toxicity. These agents include not only some novel psychoactive substances aka “designer drugs,” but also a wide variety of over-the-counter medications, herbal supplements, and even a household culinary spice. The care of patients in the emergency department who have used “legal high” substances is challenging. Patients may misunderstand the substance they have been exposed to, there are rarely any readily available laboratory confirmatory tests for these substances, and the exact substances being abused may change on a near-daily basis. This review will attempt to group legal agents into expected toxidromes and discuss associated common clinical manifestations and management.

BERRY, P.A.M. GLENTON, N.M. NIKOLAOU & K.S. SOH Departments of Pharmacology, Universities of Edinburgh and Bristol 1 The affinity of 17 compounds for muscarine-sensitive acetylcholine receptors in atrial pacemaker cells and ileum of the guinea-pig has been measured at 290C in Ringer-Locke solution. Measurements were also made at 370C with 7 of them. 2 Some of the compounds had much higher affinity for the receptors in the ileum than for those in the atria. For the most selective compound, 4-diphenylacetoxy-N-methylpiperidine methiodide, the difference was approximately 20-fold. The receptors in the atria are therefore different in structure from those in the ileum. 3 The effects of temperature on affinity are not the same for all the compounds tested, indicating different enthalpies and entropies of adsorption and accounting for some of the difficulty experienced in predicting the affinity ofnew compounds.

Nonetheless, repetitive and stereotypical behaviours play a key role in both animal and human behaviour. Similar behaviours are observed across species, in typical human developmental phases, and in some neuropsychiatric conditions, such as Autism Spectrum Disorder (ASD) and Intellectual Disability. This evidence led to the spread of animal models of repetitive behaviours to better understand the neurobiological mechanisms underlying these dysfunctional behaviours and to gain better insight into their role and Citation: Keller, R.; Costa, T.; origin within ASD and other disorders.
