Lumbar cerebrospinal fluid (CSF) homovanillic acid (HVA), 3-methoxy-4-hydroxyphenylglycol (MHPG), 5-hydroxyindoleacetic acid (5-HIAA), cyclic AMP (cAMP) and cyclic GMP (cGMP) were measured in chronic schizophrenics with tardive dyskinesia before and three weeks after the initial treatment with sodium valproate (VPA), cyproheptadine, oxypertine or hydroxyzine pamoate. HVA levels significantly decreased after the administration of VPA, cyproheptadine or oxypertine. Cyclic GMP levels significantly increased after the administration of VPA or cyproheptadine.

Cerebrospinal fluid (CSF) HVA, MHPG, 5-HIAA, cAMP and cGMP concentrations were measured in schizophrenic patients with tardive dyskinesia before and after a three-week administration of oxypertine (n = 4), hydroxyzine pamoate (n = 4) or placebo (n = 4). The oxypertine administration resulted in a reduction of the CSF HVA concentration and an elevation of the MHPG and cAMP concentrations, associated with a clinical improvement in tardive dyskinesia. The hydroxyzine administration reduced the CSF 5-HIAA concentration in all the patients and the CSF HVA concentration in two of four patients with a clinical improvement.
