The behavioral pharmacology of tandospirone (SM 3997), a novel anxiolytic/antidepressant pyrimidinylpiperazine compound with selective pharmacological effects at the 5-HT1A binding site, was investigated in baboons. Animals administered 50 mg/kg/day i.g. tandospirone, showed few behavioral changes (lip droop, ataxia), which decreased over 2 weeks. Substitution of vehicle for tandospirone after 7 weeks produced time-limited suppression of food intake, suggesting a mild withdrawal syndrome. Under an i.v. self-injection procedure, tandospirone (1.0-32 mg/kg/injection) did not maintain responding greater than vehicle, although cocaine and triazolam did. Under a drug discrimination procedure, tandospirone (1-3.2 mg/kg p.o.; 0.1-32 mg/kg, i.m.) did not occasion drug-appropriate responding in baboons trained to discriminate lorazepam or pentobarbital and buspirone (1-18 mg/kg, p.o.; 0.1-1.0 mg/kg, i.m.) did not occasion drug-appropriate responding in the pentobarbital-training group. Tandospirone's profile of effects differs from those for barbiturates and benzodiazepines and suggests low abuse liability.

We reported a 74-year-old male case of progressive supranuclear palsy (PSP) who responded to tandospirone citrate, a serotonin receptor (5-HT1A) agonist. The patient manifested postural instability and gait disturbance at 71 years. Additionally, he showed vertical gaze paresis, regidity of the neck, extremities and trunk, bradykinesia and mild cognitive impairment. A brain MRI revealed moderate atrophy of bilateral frontal/temporal lobes and of midbrain tegmentum one year after the onset. The patient had been diagnosed as PSP and treated with L-DOPA. However, L-DOPA therapy showed only transient response for a few months. His symptoms deteriorated gradually, and he became unable to sit, stand up or walk by himself. Tandospirone citrate was additionally administered at 30 mg/day. Rigidity and bradykinesia were remarkably improved in two weeks after the start of tandospirone treatment. He became able to stand up and walk a short distance with supports in four weeks. Cognitive disturbance was also slightly improved. Tandospirone citrate was effective on our case of PSP, especially on rigidity. Our findings suggest that combination of levodopa and tandospirone citrate is a useful therapy for PSP.

Tandospirone citrate (tandospirone) is an anti-anxiety drug that acts by combining with serotonin receptor (5-hydroxytryptamine-1 A [5-HT1A]). Recently, there have been a few reports of its potential role in the treatment of cerebellar ataxia. We report the first case of a patient with Machado-Joseph disease in which we successfully treated cerebellar ataxia. In addition, his leg pain, insomnia, anorexia, and depression, which are thought to be related to 5-HT1A receptors, were also remarkably alleviated by treatment with tandospirone.
