Cocaine effects on sleep parameters in the rat. 1977

S Y Hill, and W B Mendelson, and D A Bernstein

Cocaine in 6 mg/kg doses was administered orally and intraperitoneally to rats and sleep EEG's recorded. Cocaine significantly reduced total sleep time, slow-wave sleep, and sleep latency. Rapid eye movement sleep (REM) was significantly suppressed during the first half of the sleep recording. These effects were evident by both routes of administration. The effects of cocaine on total sleep time in animals parallels that observed in man.

UI	MeSH Term	Description	Entries
D007274	Injections, Intraperitoneal	Forceful administration into the peritoneal cavity of liquid medication, nutrient, or other fluid through a hollow needle piercing the abdominal wall.	Intraperitoneal Injections,Injection, Intraperitoneal,Intraperitoneal Injection

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.
