Establishing a dose-response relationship for haloperidol decanoate

Reduced haloperidol/haloperidol ratios after oral haloperidol and decanoate administration in schizophrenics.

1. Haloperidol and reduced haloperidol plasma concentrations were measured in thirteen stable schizophrenic patients that received both oral haloperidol and haloperidol decanoate. 2. Significant correlations between reduced haloperidol/haloperidol ratios from oral haloperidol and haloperidol decanoate occurred at week two and week 16, respectively. 3. The formation of RH was consistent during h...

Haloperidol decanoate in chronic schizophrenia: a study of 12 months with plasma levels.

1. Clinical activity, extrapyramidal side-effects were evaluated in 22 schizophrenic out patients diagnosed according to DSM III and treated with haloperidol decanoate (50-300 mg i.m. monthly dose) for 12 months. 2. BPRS total scores did not show significant fluctuations showing a clinical stability of the patient population. 3. Patients with a duration of illness greater than 10 yrs (Group 2) ...

Haloperidol decanoate doses of 200, 100, or 50 mg/month reduced symptomatic exacerbations more than a 25 mg/month dose in schizophrenia.

Number needed to treat and number needed to harm with paliperidone palmitate relative to long-acting haloperidol, bromperidol, and fluphenazine decanoate for treatment of patients with schizophrenia

BACKGROUND We analyzed data retrieved through a PubMed search of randomized, placebo-controlled trials of first-generation antipsychotic long-acting injectables (haloperidol decanoate, bromperidol decanoate, and fluphenazine decanoate), and a company database of paliperidone palmitate, to compare the benefit-risk ratio in patients with schizophrenia. METHODS From the eight studies that met ou...

Effectiveness of paliperidone palmitate vs haloperidol decanoate for maintenance treatment of schizophrenia: a randomized clinical trial.

IMPORTANCE Long-acting injectable antipsychotics are used to reduce medication nonadherence and relapse in schizophrenia-spectrum disorders. The relative effectiveness of long-acting injectable versions of second-generation and older antipsychotics has not been assessed. OBJECTIVE To compare the effectiveness of the second-generation long-acting injectable antipsychotic paliperidone palmitate...
