A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here The mechanism by which this occurs is through delayed release after ingestion (unlike some other psychostimulant drugs, which may be abused). After oral administration and absorption, enzyme hydrolysis after contact with red blood cells metabolize lisdexamfetamine into L- lysine , a naturally occurring essential amino acid and active d-amphetamine , which is responsible for the drug's pharmacological effects Mesocarb is a novel, selective, repositioned, small molecule therapeutic candidate, being developed by Melior Pharmaceuticals (spin-off of Melior Discovery) These drugs can act through several mechanisms, such as directly activating postsynaptic receptors, blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines Its mechanism of action is similar to other appetite suppressants such as sibutramine, phentermine and dextroamphetamine. Chemically, it is the N-ethyl homologue of cathinone and dimethylcathinone. Side effects Severe Insomnia Pulmonary hypertension Stroke Psychosis Cardiovascular Tachycardia, hypertension, arrhythmia, chest pai
In comparison with mesocarb it has own antidepressant activity, which makes it useful in treating depressions. Indications of feprosidnine included apathic, asthenic depressions, fatique, apathic syndrome, narcolepsy and other similar conditions. Therapeutic range of doses: 10-50mg a day. Sydnophen has multiple mechanisms of action, the relative importance of which has not been clearly established. Effects on the body include reversible monoamine oxidase inhibition It releases dopamine by a similar mechanism to amphetamines, but is 10x less potent than dexamphetamine at producing this effect. The main mechanism of action is instead inhibition of dopamine reuptake, more similar to that of methylphenidate Dopamin-Wiederaufnahmehemmer. Dopamin-Wiederaufnahmehemmer ( DRI, DARI für D op a mine R euptake I nhibitors) sind Arzneistoffe, die durch die Blockierung des Dopamin- Transporter die präsynaptische Aufnahme des Botenstoffs Dopamin hemmen und so die extrazelluläre Konzentration erhöhen The mechanism of action of aspirin involves irreversible inhibition of the enzyme cyclooxygenase; therefore suppressing the production of prostaglandins and thromboxanes, thus reducing pain and inflammation. This mechanism of action is specific to aspirin, and is not constant for all nonsteroidal anti-inflammatory drugs (NSAIDs). Rather, aspirin is the only NSAID that irreversibly inhibits COX-1 Action to strengthen international cooperation to control precursors and their substitutes used in the illicit manufacture of controlled substances, in particular amphetamine-type stimulants, and to prevent their diversion
Currently, pharmaceutical amphetamine is prescribed as racemic amphetamine, Adderall, dextroamphetamine, or the inactive prodrug lisdexamfetamine. Amphetamine increases monoamine and excitatory neurotransmission in the brain, with its most pronounced effects targeting the norepinephrine and dopamine neurotransmitter systems Als Stimulanzien oder Psychostimulanzien werden psychoaktive Substanzen bezeichnet, die anregend auf den Organismus wirken. Der Begriff Stimulans leitet sich von lateinisch stimulare ab. Die Weltgesundheitsorganisation definiert Stimulanzien als Substanzen, welche die Aktivität der Nerven erhöhen, beschleunigen oder verbessern. Andere Bezeichnungen sind Stimulantia, Psychotonika, Psychoanaleptika, Aufputschmittel oder englisch und umgangssprachlich Upper. Das Gegenteil dieser.

This system shall build on existing mechanisms under WTO obligations, especially Article 7 of the WTO SPS Agreement. 4. promotion of transparency as regards the sampling, analysis and action following official controls on feed and food from either Party. ARTICLE 40. Competent Authorities. 1 Mechanism of action. Rotenone works by interfering with the electron transport chain in mitochondria. To be specific, it inhibits the transfer of electrons from iron-sulfur centers in complex I to ubiquinone. This interferes with NADH during the creation of usable cellular energy . Complex I is unable to pass off its electron to CoQ, creating a back-up of electrons within the mitochondrial.
In the 70s in the USSR, the list of psychostimulant drugs consisted of two means: Sidnokarb (sometimes produced as Mesocarb) and Sidnofen (Fenprozidin). Both funds are actively used in medicine. Since their mechanism of action allowed us to achieve exceptional results for the maintenance of the forces of the body by those standards. In the early 90s, drugs disappeared from free sale. The mechanism of action of modafinil is highly debated. An interaction or involvement of alpha 1-adrenergic systems was initially suggested by the ability of the alpha 1 antagonist, prazosin, to antagonize modafinil-induced increases in motor activity in mice 81 and wakefulness in cats. 82 However, modafinil does not bind to alpha 1 receptors in vivo (Ki greater than 10-3 M, obtained from. 188.8.131.52.4.1 Mechanism of action. As with related compounds, benzphetamine is classed as a sympathomimetic and CNS stimulant. Presumably, benzphetamine produces its effects through mechanisms similar to amphetamine, but a review of the literature failed to reveal studies that have actually demonstrated the mechanism of action of benzphetamine. The side-effect profile has been reported to be.
Hydroxy-mesocarb (II), dihydroxy-mesocarb (III), amphetamine (VII) and the conjugates of II and III account for 86% of the urinary radioactivity. 3. Cannulated male rats excrete about 40% of the. Finally, a screening method to detect the administration of mesocarb in routine antidoping control analyses was proposed and validated based on the detection of the main mesocarb metabolites in. However, many stimulant drugs have additional (or exclusive) direct actions at subtypes of receptor, and these direct actions can explain major differences in types of stimulant action. Even considering adrenergic synapses, there are a large number of possible postsynaptic receptors as targets for sympathomimietic agonists, α1A, α1B, α1D, α2A, α2B and α2C, and this does not even consider.
Mechanism of action. Precise mechanism of antidepressant activity of SSRIs remains somewhat uncertain, but a number of biochemical functions associated with SSRI treatment have been established.  SSRIs primarily inhibit SERT in the brain and have negligible effects on DAT and NET Work was carried out to determine the effectiveness and mechanism of action of Phenotropil at a dose of 100 mg in the morning for a month in 20 patients who underwent IS . The patients underwent a complete general clinical, neurological and immunological examination and were divided into 2 groups. The first included 7 patients over 60 years of age with a pronounced neurological defect. The precise direct molecular mechanism of action by which bromantane ultimately acts as a dopamine synthesis enhancer is unknown.   However, it has been determined that activation of certain cAMP- , Ca 2+ - , and phospholipid -dependent protein kinases such as protein kinase A and especially protein kinase C corresponds with the manifestation of the pharmacological effects of bromantane Pharmacotherapeutic uses. The following drugs have DRI action and have been or are used clinically specifically for this property: amineptine, dexmethylphenidate, difemetorex, fencamfamine, lefetamine, levophacetoperane, medifoxamine, mesocarb, methylphenidate, nomifensine, pipradrol, prolintane, and pyrovalerone.The following drugs are or have been used clinically and possess only weak DRI.

Indications of feprosidnine included apathic, asthenic depressions, fatique, apathic syndrome, narcolepsy and other similar conditions. Therapeutic range of doses: 10-50mg a day. Sydnophen has multiple mechanisms of action, the relative importance of which has not been clearly.
Mechanism of action. Metoclopramide was first described by Dr. Louis Justin-Besançon and C. Laville in 1964. It appears to bind to dopamine D 2 receptors with nanomolar affinity (Ki 28.8 nM), where it is a receptor antagonist, and is also a mixed 5-HT 3 receptor antagonist/5-HT 4 receptor agonist Mechanism of action. Reserpine irreversibly blocks the H +-coupled vesicular monoamine transporters, VMAT1 and VMAT2. VMAT1 is mostly expressed in neuroendocrine cells. VMAT2 is mostly expressed in neurons. Thus, it is the blockade of neuronal VMAT2 by reserpine that inhibits uptake and reduces stores of the monoamine neurotransmitters norepinephrine, dopamine, serotonin and histamine in the.

Mechanism of action. The mechanism through which dapoxetine affects premature ejaculation is still unclear, but dapoxetine is presumed to work by inhibiting serotonin transporter and subsequently increasing serotonin's action at pre- and postsynaptic receptors. Human ejaculation is regulated by various areas in the central nervous system (CNS) Mechanisms of action The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists , β-adrenergic agonists , and dopaminergic agonists ; or indirect-acting (interaction not between drug and receptor), such as MAOIs , COMT inhibitors , release stimulants, and reuptake inhibitors that increase the levels of endogenous. Consumption of amfetamine-type stimulants, including classical amfetamines and 'designer drugs', has been recognised as one of the most significant trends in drug abuse at the end of the past century and at the beginning of the current one. The first cause is the increasing consumption amongst youth of methylenedioxy- and methoxy-substituted amfetamines, of which the pharmacology in humans.

Dextroamphetamine affects the dynamics neurotransmitter systems, and its mechanisms of action are continuously being investigated and discovered. Monoamines . Dextroamphetamine affects dopamine and serotonin levels in the caudate, and norepinephrine in the hippocampus. Because dextroamphetamine is a substrate analog at monoamine transports, at all doses, dextroamphetamine prevents the reuptake. Mechanisms of action. The mechanisms of sympathomimetic drugs are to act as catecholamine synthesis precursors, norepinephrine transporter blockade, adrenergic receptor agonism, inhibition of epinephrine and norepinephrine metabolism and/or cholinergic inhibition. Synthesis precursor. Synthesis precursors of catecholamines stimulate the catecholamine synthesis. One example is levodopa. Phenibut is a derivative of the inhibitory neurotransmitter GABA. It has been widely used for medical purposes in Russia and former Soviet countries, whereas it is a non-prescription and unapproved (though legal) drug in most other regions. It has stress-reducing, anxiolytic, and sedative effects. At common doses it is often easier to be alert and [ Mechanism of action. All or part of this article may be confusing or unclear. Please help clarify the article. Suggestions may be on the talk page. (October 2007) Amphetamines, both as dextroamphetamine and levoamphetamine (or a racemic mixture of the two enantiomers), are believed to exert its effects by binding to the monoamine transporters and increasing extracellular levels of the biogenic.

Phentermine is an appetite suppressant of the amphetamine and phenethylamine class.. It is approved as an appetite suppressant to help reduce weight in obese patients when used short-term and combined with exercise, diet, and behavioral modification . Fencamfamine acts as an indirect dopamine agonist.It releases dopamine by a similar mechanism to amphetamines, but is 10x less potent than dexamphetamine at producing this effect. The main mechanism of action is instead inhibition of dopamine reuptake, more similar to that of methylphenidate.Also unlike amphetamines, fencamfamine does not inhibit the action of monoamine oxidase.

Retrieved on 2007-08-18 Amphetamine exerts its behavioral effects by modulating several key neurotransmitters in the brain, including dopamine, serotonin, and norepinephrine.However, the activity of amphetamine throughout the brain appears to be specific;  certain receptors that respond to amphetamine in some regions of the brain tend not to do so in other regions. For instance, dopamine D2 receptors in the. Several animal studies suggest that the substance is safe even when high doses are consumed for a long period of time. However the mechanism of action of oxiracetam is still a matter of research.. See also. Racetam
All stimulants destabilize the action of the hypothalamus on the pituitary. Under controlled conditions the hypothalamus secretes thyroid-releasing hormone (TRH).This then stimulates the pituitary to release thyroid-stimulating hormone (TSH). Generally when 1 ampule of TRH (Protirelin) is injected into a vein, 5-10 ug of TSH is detected in the bloodstream after 20 minutes. The amount of TSH. Mechanisms of action. Piracetam's mechanism of action, as with racetams in general, is not fully understood. The drug influences neuronal and vascular functions and influences cognitive function without acting as a sedative or stimulant.  Piracetam is a positive allosteric modulator of the AMPA receptor.  It is hypothesized to act on ion channels or ion carriers,  thus.
The mechanism of bromantane action is based on the facility to increase the activity of the lower centers of the central nervous system (the hypothalamus nuclei, the reticular nuclei of the operculum, the hippocampus). It does not exert any expressed action on noradrenergic mediators, but implements the activation properties through the dopaminergic system. Bromantane strengthens GABA-ergic. .
