PHARMACEUTICAL FORM NOOTROPIL Tablet 800 and 1200 mg: white, oblong, film-coated tablet, with a bisect line, marked N/N on one side and plain on the other side NOOTROPIL Oral Solution 20%: clear colourless solution INDICATIONS 1. Studies carried out in the elderly suffering from loss of memory, vertigo, a lack of concentration or of alertness, changes of mood, a deterioration in behaviour and personal negligence, demonstrate an improvement in symptoms. These symptoms can also provide an early warning of the onset of pathological ageing such as Alzheimer’s Disease, an Alzheimer type of senile dementia, or the dementia produced by multiple cerebral infarcts. 2. NOOTROPIL is advocated in the treatment of sickle-cell vaso-occlusive crises. 3. Studies have shown some improvement in children with learning difficulties associated with the written word, particularly with textual understanding which cannot be explained by intellectual backwardness, inadequate education or by the family environment. The administration of NOOTROPIL does not replace other measures also well adapted to correct these learning difficulties, such as remedial teaching. DOSAGE AND ADMINISTRATION Oral formulations 1 NOOTROPIL should be administered orally, and may be taken with or without food. -

Chronic alcohol consumption results in strengthened excitatory neurotransmission and increased AMPA receptor signaling in animal models. However, the mechanistic role of enhanced AMPA receptor activity in alcohol reinforcement and alcohol- seeking behavior remains unclear. This study examined the role of enhanced AMPA receptor function using the selective positive allosteric modulator, aniracetam, in modulating operant alcohol self-administration and cue-induced reinstatement. Male alcohol-preferring (P-) rats, trained to self-administer alcohol (15%, v/v) versus water were pretreated with aniracetam to assess effects on maintenance of alcohol self-administration. To determine reinforcer specificity, P-rats were trained to self-administer sucrose (0.8%, w/v) versus water, and effects of aniracetam were tested. -

Cognitive Enhancing Agents: Current Status in the Treatment of Alzheimer's Disease
LE JOURNAL CANADIEN DES SCIENCES NEUROLOGIQUES REVIEW ARTICLE Cognitive Enhancing Agents: Current Status in the Treatment of Alzheimer's Disease Cheryl Waters ABSTRACT: Extensive recent literature on drugs used to enhance cognitive functioning, reflects the growing social problem of dementia. Many clinical trials have been undertaken with variable success. In most cases the disorder stud ied has been Alzheimer's disease. The pharmacological approach has been designed to rectify the presumed patho physiological processes characteristic of the condition. Agents tested include cerebral vasodilators, cerebral metabolic enhancers, nootropics, psychostimulants, neuropeptides and neurotransmitters with a special emphasis on drugs used to enhance cholinergic function. Ethical and practical issues concerning clinical drug trials in dementia will be discussed. RESUME: Stimulation cognitive medicamenteuse: etat de la question dans le traitement de la maladie d'Alzheimer La multiplicity des publications recentes sur les medicaments utilises pour stimuler le fonctionnement cognitif est le reflet du probl&me social sans cesse croissant de la d6mence. Plusieurs essais cliniques ont ete tentes avec des resultats variables. Dans la plupart des cas, la maladie etudiee etait la maladie d'Alzheimer. L'approche pharmacologique a ete con^ue pour corriger les processus physiopathologiques caracteristiques de la maladie. Les agents etudies incluent des vasodilatateurs cerebraux, des stimulants metaboliques cerebraux, des agents nootropes, des agents neurotropes, -
Designing a Formulation of the Nootropic Drug Aniracetam Using 2-Hydroxypropyl-Β-Cyclodextrin Suitable for Parenteral Administration
pharmaceutics Article Designing a Formulation of the Nootropic Drug Aniracetam Using 2-Hydroxypropyl-β-Cyclodextrin Suitable for Parenteral Administration Sebastian D. Goldsmith and Arlene McDowell * School of Pharmacy, University of Otago, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +64-3479-7145 Received: 17 October 2018; Accepted: 15 November 2018; Published: 18 November 2018 Abstract: The nootropic drug aniracetam is greatly limited in its application by low aqueous solubility and a poor oral bioavailability. The primary aim of this study was to design a parenteral formulation of aniracetam that can be administered intravenously. Complexation of aniracetam with 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) was investigated as a strategy to enhance solubility. A phase solubility analysis was performed to quantify the extent of improvement. An 819% increase in the solubility of aniracetam was obtained, reaching 36.44 mg/mL. This marked increase enables aniracetam to exist in an aqueous solvent at levels sufficient for parenteral dosing. A stability test was then devised using a design of experiment approach. The aniracetam-HP-β-CD formulation was subjected to different relative humidity and temperature and cyclodextrin concentrations over a 12-week period. Key changes in FTIR vibrational frequencies suggest the benzene moiety of aniracetam was introduced into the hydrophobic cavity of HP-β-CD. These results are highly supportive of the formation of a predictable 1:1 molar stoichiometric inclusion complex, explaining the improvement seen in physiochemical properties of aniracetam following formulation with HP-β-CD. This novel formulation of aniracetam suitable for parenteral administration will have utility in future studies to further elucidate the pharmacokinetics of this drug. -
Mechanism of Positive Allosteric Modulators Acting on AMPA Receptors
The Journal of Neuroscience, September 28, 2005 • 25(39):9027–9036 • 9027 Cellular/Molecular Mechanism of Positive Allosteric Modulators Acting on AMPA Receptors Rongsheng Jin,1 Suzanne Clark,4 Autumn M. Weeks,4 Joshua T. Dudman,2 Eric Gouaux,1,3 and Kathryn M. Partin4 1Department of Biochemistry and Molecular Biophysics, 2Center for Neurobiology and Behavior, and 3Howard Hughes Medical Institute, Columbia University, New York, New York 10032, and 4Department of Biomedical Sciences, Division of Neuroscience, Colorado State University, Fort Collins, Colorado 80523 Ligand-gated ion channels involved in the modulation of synaptic strength are the AMPA, kainate, and NMDA glutamate receptors. Small molecules that potentiate AMPA receptor currents relieve cognitive deficits caused by neurodegenerative diseases such as Alzheimer’s disease and show promise in the treatment of depression. Previously, there has been limited understanding of the molecular mechanism of action for AMPA receptor potentiators. Here we present cocrystal structures of the glutamate receptor GluR2 S1S2 ligand-binding domain in complex with aniracetam [1-(4-methoxybenzoyl)-2-pyrrolidinone] or CX614 (pyrrolidino-1,3-oxazino benzo-1,4-dioxan-10- one), two AMPA receptor potentiators that preferentially slow AMPA receptor deactivation. Both potentiators bind within the dimer interface of the nondesensitized receptor at a common site located on the twofold axis of molecular symmetry. Importantly, the poten- tiator binding site is adjacent to the “hinge” in the ligand-binding core “clamshell” that undergoes conformational rearrangement after glutamatebinding.Usingrapidsolutionexchange,patch-clampelectrophysiologyexperiments,weshowthatpointmutationsofresidues that interact with potentiators in the cocrystal disrupt potentiator function. We suggest that the potentiators slow deactivation by stabilizing the clamshell in its closed-cleft, glutamate-bound conformation. -
