Risperidone in the treatment of Hispanic inpatients with schizophrenia: a pilot study.

A growing body of scientific evidence over the last two decades suggests that certain ethnic groups may require lower dosages of standard antipsychotics for the treatment of schizophrenia symptoms. Recent studies have implicated the role of genetic and environmental factors in the metabolism of these drugs as the basis for this differential response. In this pilot study, 10 Hispanic and 8 non-Hispanic patients with schizophrenia were enrolled in a double-blind, parallel-group, inpatient risperidone dosing (daily versus twice daily) trial with the novel antipsychotic risperidone.

Diagnosis and treatment of endometriosis.

Endometriosis is a chronic and progressive disease that affects approximately 10% of women of reproductive age. Its aetiology remains unknown, however, factors such as retrograde menstruation, heredity, impaired immune function and environmental toxins have been implicated. Laparoscopy is still considered the mainstay for diagnosis, however non-invasive diagnostic methods such as transvaginal ultrasound and MRI may also be complementary.

Brasofensine treatment for Parkinson's disease in combination with levodopa/carbidopa.

Objective: To investigate the safety, tolerability, pharmacokinetic, and pharmacodynamic properties of the dopamine transporter antagonist brasofensine (BMS-204756) in patients with Parkinson's disease receiving levodopa/carbidopa treatment.

Methods: A 4-period crossover study was performed in 8 men (mean age 66 y) with moderate Parkinson's disease (Hoehn-Yahr stage II-IV). A dose escalation study was used in which each patient was given a single oral dose of brasofensine 0.
