Serum calcium and magnesium levels in chronic schizophrenics. 1983

Serum calcium and magnesium levels were studied during neuroleptic treatment in a group of 29 chronic schizophrenic inpatients who had previously remained drug free for at least 4 weeks. The drug-free values of both electrolytes were not significantly different between patients and controls. In three patients who developed catatonic stupor during the drug-free period, calcium was significantly increased at the onset of the catatonic manifestations. Both electrolytes were significantly decreased in the whole group during treatment; the magnitude of the decrease was independent of the neuroleptic used. No correlation was found between the observed increase in prolactin and calcium changes. Patients who remained free of extra-pyramidal symptoms had a higher mean drug-free magnesium to calcium ratio compared to those who developed such symptoms. Our study provides evidence for an interconnection between serum electrolyte changes and neuroleptic drug action.

D010868 Pimozide A diphenylbutylpiperidine that is effective as an antipsychotic agent and as an alternative to HALOPERIDOL for the suppression of vocal and motor tics in patients with Tourette syndrome. Although the precise mechanism of action is unknown, blockade of postsynaptic dopamine receptors has been postulated.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D004409 Dyskinesia, Drug-Induced Abnormal movements, including HYPERKINESIS; HYPOKINESIA; TREMOR; and DYSTONIA, associated with the use of certain medications or drugs. Muscles of the face, trunk, neck, and extremities are most commonly affected. Tardive dyskinesia refers to abnormal hyperkinetic movements of the muscles of the face, tongue, and neck associated with the use of neuroleptic agents (see ANTIPSYCHOTIC AGENTS).
