"Remoxipride"

Summary data of potency and parameter information from semi-mechanistic PKPD modeling of prolactin release following administration of the dopamine D2 receptor antagonists risperidone, paliperidone and remoxipride in rats We provide the reader with relevant data related to our recently published paper, comparing two mathematical models to describe prolactin turnover in rats following one or two doses of the dopamine D2 receptor antagonists risperidone, paliperidone and remoxipride, "A comparison of two semi-mechanistic models for prolactin release and prediction of receptor occupancy following administration of dopamine D2 receptor antagonists in rats" (Taneja et al., 2016) [1]. All information is tabulated. Summary level data on the in vitro potencies and the physicochemical properties

Once-daily controlled release remoxipride is equieffective with twice-daily immediate release remoxipride in the treatment of schizophrenia. A controlled release (CR) formulation of remoxipride (Roxiam(®), Astra) given once-daily was compared to immediate release (IR) remoxipride given twice-daily, with respect to efficacy and tolerability, in a 4-week multicentre parallel-group dose titration (200-600 mg/day) study with acutely ill schizophrenic patients. Forty- three patients received remoxipride CR (mean dose 344 mg/day) and 49 patients received remoxipride IR (mean dose 346 mg/day). Efficacy was assessed using the Kolakowska version of the Brief Psychiatric Rating Scale (BPRS score of ≥ 18 points at entry) and the Clinical Global Impression scale (CGI), while extrapyramidal symptoms

The effects of remoxipride and chlorpromazine on eye movements and psychomotor performance in healthy volunteers. Fifteen healthy male volunteers received single doses of 100 mg immediate release remoxipride (IR), 150 mg controlled release remoxipride (CR), 50 mg chlorpromazine (CPZ), 2 mg lorazepam (LZ), and placebo in a randomised, five-period cross-over study. Both saccadic (SEM) and smooth

receptor occupancy and plasma prolactin concentrations in humans following administration of paliperidone or remoxipride. Data on male Wistar rats receiving single or multiple doses of risperidone, paliperidone, or remoxipride was described by two semimechanistic models, the precursor pool model and the agonist-antagonist interaction model. Using interspecies scaling approaches, human D receptor occupancy and plasma prolactin concentrations were predicted for a range of clinical paliperidone and remoxipride doses. The predictions were compared with corresponding observations described in literature as well as with predictions from published models developed on human data. The pool model could predict D receptor occupancy and prolactin response in humans following single doses of paliperidone

agonist (Sumanirole) and antagonist (SCH23390, Remoxipride) at a low and high dose through 3 days of training. The D1R-like-agonist at both doses enhanced working memory at day 1 but only in the low dose treated rats enhancement persists over training compared to control rats. Rats treated with a high dose of a D1R-like-antagonist show persistent enhancement of working memory over training, whereas

Neuroendocrine responses to single oral doses of remoxipride and sulpiride in healthy female and male volunteers. Six female and six male healthy volunteers received 100 mg remoxipride, 200 mg sulpiride and placebo as single oral doses in a double blind trial with a randomized crossover design. The main objective was to compare the effect of the two drugs on serum prolactin levels, but effects on other hormones were also investigated. Remoxipride and sulpiride increased the serum levels of prolactin to similar peak levels. This effect was larger in female than in male subjects. Sulpiride increased prolactin levels at much lower plasma concentrations than remoxipride, and sulpiride's effect on prolactin lasted for considerably longer than remoxipride's. No consistent effects on serum levels

Effect of urinary pH on the plasma and urinary kinetics of remoxipride in man. The influence of urinary pH on the plasma and urinary kinetics of remoxipride in man has been studied in an open crossover trial in ten healthy male volunteers. Ammonium chloride (urinary pH 5.2) and sodium hydrogen carbonate (urinary pH 7.8) were used as pretreatments on two occasions in randomized order. On each occasion remoxipride 50 mg solution was administered orally and plasma and urinary concentrations of the drug were determined by HPLC and plasma prolactin concentrations by RIA. Remoxipride was rapidly distributed in the body according to a one-compartment model. The mean plasma elimination half-life (t1/2) was 3.6 h in the ammonium chloride experiment and 6.2 h in the sodium hydrogen carbonate

A double blind comparative multicentre study of remoxipride and haloperidol in schizophrenia. Seventy-two patients fulfilling the DSM-III criteria for schizophrenia and schizophreniform psychosis were admitted to a multicentre, double-blind controlled study to evaluate the efficacy and safety of remoxipride in comparison to haloperidol. The mean daily dose of remoxipride at the end of treatment was 353 mg and of haloperidol, 11 mg. Patients were assessed each week on the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression (CGI) and the symptoms checklist. No significant differences in efficacy were found between the two treatments. The median total BPRS score in the remoxipride group was 25 at start of active treatment and 17 at the last valid rating (n = 31

A double-blind multicentre study comparing remoxipride, controlled release formulation, with haloperidol in schizophrenia. A double-blind multicentre study was undertaken to compare the efficacy and safety of remoxipride in a controlled release (CR) formulation given once daily with haloperidol twice daily in patients with schizophrenic illness. In total, 114 patients were included. All were diagnosed as schizophrenic or schizophreniform according to DSM-III. Their mean daily dose of remoxipride CR during the last week of treatment was 385 mg. In the haloperidol group the corresponding dose was 17 mg per day. The intended study period was 4 weeks with at least a one-day washout. No significant differences were found between treatments regarding efficacy variables. The median total Brief

A double-blind comparative study of remoxipride and haloperidol in acute schizophrenia. Seventy-one patients were entered into a multicentre, double-blind randomized study to compare the efficacy and safety of remoxipride with those of haloperidol in the acute treatment of schizophrenia or schizophreniform disorder. The patients, who were well-matched regarding demographic characteristics, were aged 18-64 years. Four patients in the remoxipride group and 6 in the haloperidol group discontinued treatment prematurely. The mean daily doses during the last week of treatment were 363 mg remoxipride and 9 mg haloperidol. At this time 22% of patients on remoxipride and 66% of those on haloperidol were taking anticholinergics (p less than 0.001). The clinical efficacy was similar in both groups

A placebo-controlled clinical trial of remoxipride and chlorpromazine in newly admitted schizophrenic patients with acute exacerbation. We carried out a four-week double-blind placebo-controlled study comparing remoxipride (n = 20) to chlorpromazine (n = 21) and placebo (n = 21) in the treatment of newly admitted schizophrenic patients with acute exacerbation. Chlorpromazine was found to be significantly better than remoxipride on the dropout rate due to inefficacy, Clinical Global Impression (CGI) of severity of illness and Brief Psychiatric Rating Scale (BPRS). Chlorpromazine tended to be better than placebo on the dropout rate related to inefficacy, Nurse's Global Impression (NGI) of severity and on the BPRS measures of positive symptoms (hallucinatory behaviour and thinking disturbance

Remoxipride and haloperidol in the acute phase of schizophrenia: a double-blind comparison. The efficacy and safety of remoxipride in the treatment of schizophrenia were compared with those of haloperidol in a multicentre double-blind 6-week study which was randomized with a parallel group design and was preceded by a washout period. Eighty-nine consecutively admitted men and women meeting the Research Diagnostic Criteria for schizophrenia in an acute phase of the illness were treated with remoxipride 75-300 mg twice daily or haloperidol 5-20 mg twice daily. The efficacy assessments were the Brief Psychiatric Rating Scale, Krawiecka Rating Scale, and Clinical Global Impression. Both antipsychotic drugs produced clinical improvement with no significant differences between the efficacy

A double-blind comparative study of remoxipride and haloperidol in schizophrenic and schizophreniform disorders. The antipsychotic effect of remoxipride was compared to that of haloperidol in a randomized double-blind study with parallel group design comprising 98 patients with schizophrenia or schizophreniform disorder according to DSM-III. After a 3-7 day placebo washout period, patients received either 150-600 mg of remoxipride or 5-20 mg of haloperidol daily for 6 weeks. No significant differences in efficacy were found between the two treatments. Treatment-emergent checklist symptoms such as hypokinesia, rigidity, and tremor occurred more frequently and were more severe during haloperidol than during remoxipride treatment despite a significantly higher concurrent use

Pharmacokinetics of remoxipride in elderly psychotic patients. The pharmacokinetics of remoxipride when given as single doses of 50 mg and repeated doses of 50 mg, 100 mg, and 200 mg twice daily to 10 elderly psychotic patients (71-89 years) were compared with the findings of two other studies to reveal any age-related differences. The three studies comprised a total of 38 patients in three distinct age groups: elderly (71-89 years), middle-aged (46-69 years) and young (19-36 years). AUC, Cmax and Cmin of both total and unbound remoxipride increased with increasing age. The unbound fraction was similar in the three age groups. The half-life was prolonged in the elderly, most probably caused by a decrease in intrinsic clearance. A two-fold increase in AUC of both total and unbound

Experiences of long-term treatment with remoxipride: efficacy and tolerability. An international clinical trial programme was undertaken to evaluate the clinical safety and tolerability of remoxipride during a 12 month long-term study and to evaluate safety, tolerability and efficacy of remoxipride for up to 6 months in a double-blind comparison with haloperidol. A total of 145 patients were treated with remoxipride for at least 12 months. In the double-blind evaluation 106 patients on remoxipride and 50 on haloperidol were included. The doses of remoxipride ranged between 90-600 mg daily and of haloperidol between 5-45 mg daily. The therapeutic efficacy of remoxipride obtained in short-term studies was maintained during long-term treatment in most patients and was similar
