title: Behavioural effects of long-term administration of fencamfamine: neurochemical implications.
abstract: The repeated effects of fencamfamine administration (10.0 mg/kg, i.p. single dose) were studied in male rats. Fencamfamine treatment increased stereotyped sniffing and decreased rearing behaviour. These changes occurred after 8 days of treatment and remained for 25 days. The fencamfamine repeated administration enhanced the homovanillic acid (HVA) level in the tubercullum olfactorium while the same treatment decreased the dihydroxyphenilacetic acid (DOPAC) and HVA striatal levels. The data suggest that long-term fencamfamine administration develops changes in the activity of parts of the DA systems which might be responsible for tolerance or sensitization to the effects of fencamfamine.
