The novel tricyclic antidepressant drug tianeptine had an antidepressant-like effect on a rat model of depression based on the deficit in open field activity observed on the day after 2 h restraint. Thus, when tianeptine (10 mg/kg IP) was given 2 h after the end of the restraint to either untreated rats or to animals previously given 10 mg/kg of the drug per day for 13 days, then the deficit was opposed. Tianeptine, given acutely but not chronically, moderately enhanced the 5-HT1C receptor-dependent hypolocomotor effect of m-chlorophenylpiperazine (mCPP) but did not alter other 5-HT1 receptor subtype-dependent behaviour. Acute but not chronic tianeptine also decreased 5-HT2 receptor-dependent body shakes induced by 5-hydroxytryptophan. Shakes induced by the 5-HT2 agonist 1-(2,5-dimethoxy-4-iodophenyl)-2 aminopropane (DOI) were unaffected. The results are discussed in relation to the possible mechanism of antidepressant action of tianeptine.

Tianeptine is a novel antidepressant which uniquely facilitates 5-hydroxytryptamine (5-HT) uptake. When given in a dose of 10 mg/kg to rats pretreated with either carbidopa or phenelzine, it markedly reduced the frequency of wet-dog shakes, fore-paw treading, tremor and hind-limb abduction evoked by L-5-hydroxytryptophan (L-5-HTP) given 30 or 60 min later. This effect of tianeptine was opposite to that of paroxetine, a selective 5-HT uptake inhibitor, which greatly increased the 5-HTP-induced behavioural syndrome. In contrast, tianeptine did not affect behaviours elicited by the 5-HT receptor agonists, 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) or (+/-)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane hydrochloride (DOI), which are not substrates for the 5-HT uptake process. In spinal animals, tianeptine attenuated an ipsilateral flexor reflex, an effect opposite to that of citalopram, a selective 5-HT uptake inhibitor. These effects of tianeptine are consistent with its ability to increase 5-HT reuptake.
