[Effects of diazepam on six drug-induced locomotor hyperactivities in mice (author's transl)]. 1975

P Soubrié, and P Simon, and J R Boissier

Experiments were carried out in mice to investigate the influence of diazepam (DZP) on dexamphetamine, parachloro-N-methylamphetamine (pCMA), cocaine, morphine, trihexyphenidyl or (in MAOIs pretreated) reserpine induced motor hyperactivity. The interaction of DZP with these hyperactivities in which probably different biochemical central mechanisms are involved allows to construct a profile of action of DZP and to approach its mechanism of action. The locomotor hyperactivities induced by dexamphetamine, pCMA, morphine, cocaine were not reduced by DZP even by doses which decrease spontaneous locomotor activity; low doses of DZP enhance the hyperactivity induced by these compounds. Those induced by trihexyphenidyle or by reserpine (after MAOI) were reduced by DZP at doses which produce no decrease in spontaneous motor activity. Inasmuch as DZP at low doses potentiates the effects of 4 different substances, the results can hardly be satisfactorily explained neither by an interference of the benzodiazepine on the metabolism of the drugs or by a depression of the anxiogenic action of dexamphetamine. Even though it may be difficult to relate the antagonism of DZP on trihexyphenidyl- or on reserpine- (after MAOI) induced motor hyperactivity to the suggested anticholinergic and dopaminergic actions of DZP, these effects may partly be involved in the increase in locomotor hyperactivity induced by dexamphetamine, morphine, or cocaine. The observed effect of DZP on pCMA induced locomotor hyperactivity does not support a possible antiserotonine action often suggested to explain the effects of benzodiazepines in conflict situations.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008694	Methamphetamine	A central nervous system stimulant and sympathomimetic with actions and uses similar to DEXTROAMPHETAMINE. The smokable form is a drug of abuse and is referred to as crank, crystal, crystal meth, ice, and speed.	Deoxyephedrine,Desoxyephedrine,Desoxyn,Madrine,Metamfetamine,Methamphetamine Hydrochloride,Methylamphetamine,N-Methylamphetamine,Hydrochloride, Methamphetamine,N Methylamphetamine
D009020	Morphine	The principal alkaloid in opium and the prototype opiate analgesic and narcotic. Morphine has widespread effects in the central nervous system and on smooth muscle.	Morphine Sulfate,Duramorph,MS Contin,Morphia,Morphine Chloride,Morphine Sulfate (2:1), Anhydrous,Morphine Sulfate (2:1), Pentahydrate,Oramorph SR,SDZ 202-250,SDZ202-250,Chloride, Morphine,Contin, MS,SDZ 202 250,SDZ 202250,SDZ202 250,SDZ202250,Sulfate, Morphine
D009043	Motor Activity	Body movements of a human or an animal as a behavioral phenomenon.	Activities, Motor,Activity, Motor,Motor Activities
D012110	Reserpine	An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.	Raunervil,Raupasil,Rausedil,Rausedyl,Serpasil,Serpivite,V-Serp,V Serp
D003042	Cocaine	An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.	Cocaine HCl,Cocaine Hydrochloride,HCl, Cocaine,Hydrochloride, Cocaine
D003913	Dextroamphetamine	The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic.	d-Amphetamine,Curban,Dexamfetamine,Dexamphetamine,Dexedrine,Dextro-Amphetamine Sulfate,DextroStat,Dextroamphetamine Sulfate,Oxydess,d-Amphetamine Sulfate,dextro-Amphetamine,Dextro Amphetamine Sulfate,Sulfate, Dextroamphetamine,d Amphetamine,d Amphetamine Sulfate,dextro Amphetamine
D003975	Diazepam	A benzodiazepine with anticonvulsant, anxiolytic, sedative, muscle relaxant, and amnesic properties and a long duration of action. Its actions are mediated by enhancement of GAMMA-AMINOBUTYRIC ACID activity.	7-Chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one,Apaurin,Diazemuls,Faustan,Relanium,Seduxen,Sibazon,Stesolid,Valium
