Pimozide - is an anti-psychotic drug belonging to the di phenyl butylpiperidine group. Structurally it is similar to the butyrophenones, another very well known group of antipsychotic drugs that includes haloperidol. Pimozide exerts its anti-psychotic action by blocking pre and post synaptical central dopaminergic receptors.

Carbamazepine - it is an iminodibenzylic drug. Firstly used to treat epilepsy, it is now employed in cases of mood disorders (manic episodes, depression, bipolar disorders) and in schizoaffective disorders. Its therapeutical effects are due to actions on peripheral benzodiazepinic receptors connected to calcium channels, to potentiation of alpha 2 adrenergic receptors or to neuronal sodium channel stabilization.

Clonazepam - a benzodiazepinic drug that acts on receptors associated with GABA receptors and chloride ion channels. Like all the other members of this chemical family, clonazepam potentiates the effects of GABA on its receptor, thus increasing the influx of chloride ions to the neuron. Clonazepam is used in the treatment of epileptic attacks, panic disorders, social phobias and mood disorders ( acute mania and bipolar disorders).
