It has been suggested that nigrostriatal dopaminergic transmission is modulated by nitric oxide (NO). Since there is evidence that gonadal hormones can affect extrapyramidal motor behavior in mammals, we investigated the effects of isosorbide dinitrate (ISD), linsidomine (SIN-1) and S-nitroso-N-acetylpenicillamine (SNAP), three pharmacologically different NO donors, on neuroleptic-induced catalepsy in 60- to 80-day-old male and female albino mice. Catalepsy was induced with haloperidol (1 mg/kg, ip) and measured at 30-min intervals by means of a bar test. Drugs (or appropriate vehicle) were injected ip 30 min before haloperidol, with each animal being used only once. ISD (5, 20 and 50 mg/kg) caused a dose-dependent inhibition of catalepsy in male mice...

Drugs which influence 5-HTergic mechanisms can modify neuroleptic-induced catalepsy (NC) in rodents, a phenomenon produced by striatal dopamine (DA) receptor blockade. Previous research also suggests a role for endogenous nitric oxide (NO) in the modulation of striatal DAergic neurotransmission; in addition, NO seems to play a role in the 5-HT reuptake mechanism. It is known that clomipramine potentiates NC in mice, but the reported effects of selective 5-HT reuptake inhibitors (SSRIs) in this model are rather contradictory. We then decided to re-address this issue, investigating the effect of fluoxetine (FX), an SSRI, on NC. In view of the ubiquitous role of NO as a central neuromodulator, we also studied the effect of isosorbide dinitrate (ID), a...
