Abstract

Carbamazepine (CBZ) is known to be a potent anti-epileptic drug. Like lithium it has been reported to prevent the oscillation of manic-depressive psychosis [1][2]. Although the mechanisms of action of both drugs in the brain are not well known, it is possible that they affect some neurotransmitters or neuromodulators in a similar manner. It has been reported that chronic lithium administration increased the substance P (SP) content in the dopamine related brain areas, and co-administration of haloperidol (HAL) prevented this effect [3][4]. We have studied the effect of CBZ, HAL and trihexyphenidyl (TR) alone or in combination on SP content as well as dopamine (DA), serotonin (5HT), glutamate and γ-aminobutyric acid (GABA) in the rat brain.
