Effect of intravenous magnesium sulphate in reducing irritability and restlessness in pure and polysubstance opiate detoxification.

The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of intravenous magnesium sulphate (MgSO(4)) on the need for chlormethiazole in pure or polysubstance opiate detoxification. Forty-one inpatients suffering from pure and polysubstance opiate dependence were treated with morphine sulphate pentahydrate in a gradual detoxification program. Morphine reduction took about 11 days.

Relationship between power spectra of the awake EEG and psychomotor activity patterns measured by short-term actigraphy.

Actigraphy is a quantitative method for the measurement of motor activity. In the present study, actigraphy was used to examine psychomotor correlates of brain activity. Thirty-four psychiatric patients (17 males and 17 females) with different diagnoses participated in this investigation.

Treatment of severe mania with intravenous magnesium sulphate as a supplementary therapy.

Ten patients with severe, therapy-resistant manic agitation received magnesium sulphate infusions with a continuous magnesium (Mg) flow of approximately 200 mg/h (4353+/-836 mg/day; daily monitored Mg plasma level: 2.44+/-0.34 mmol/l) for periods ranging from 7 to 23 days.
