Effects of lithium on the kidney.

We tested kidney function in 268 patients given lithium treatment for an average period of 37.6 months and in 59 manic-depressive patients never given lithium. No patients suffered serious renal damage during the course of our observations. Maximum concentration capacity was lower and serum creatinine concentration higher in the lithium treated patients than in the controls, but the differences did not achieve statistical significance. Females had poorer concentrating ability than males, both among the control subjects and during lithium treatment. Concomitant antipsychotic drug therapy may affect concentrating ability and possibly glomerular function adversely.

Triazolam-induced brief episodes of secondary mania in a depressed patient.

Large doses of triazolam repeatedly induced brief episodes of mania in a depressed elderly woman. Features of organic mental disorder (delirium) were not present. Manic excitement was coincident with the duration of action of triazolam. The possible contribution of the triazolo group to changes in affective status is discussed.

Amoxapine for the treatment of psychotically depressed subjects. A pilot study.

The treatment of psychotic depression remains controversial, although most studies suggest that the combination of an antipsychotic and an antidepressant agent is most beneficial. The authors describe an open-label study of the treatment of psychotic depression using amoxapine, an agent with both antidepressant and antipsychotic properties. Of the six patients treated, two improved dramatically within the first week of treatment, whereas for the remaining four treatment had to be discontinued due to lack of efficacy or side effects. Amoxapine appears to be effective in some cases of psychotic depression, but side effects and known risks of treatment diminish its usefulness.

Double-blind comparison of amoxapine and imipramine in the treatment of depressed patients.

A 5-week double-blind study compared amoxapine to imipramine (2:1 dosage ratio) in the treatment of depressed outpatients. The two agents were similar in anti-depressant efficacy and rapidity of action. The most common adverse reactions to both drugs were anticholinergic effects and sedation; cardiovascular effects were minimal. A few amoxapine-treated patients developed adverse effects typical of neuroleptic drugs: some experienced extrapyramidal signs, one developed galactorrhea, and most showed elevated plasma prolactin concentrations. Amoxapine was associated with significant neuroleptic activity in plasma. No correlation was found between blood levels of either drug and therapeutic response.

Lithium prophylaxis of corticotropin-induced psychosis.

Corticotropin is one of the few accepted treatments for acute exacerbations of multiple sclerosis and retrobulbar neuritis. Psychosis is a serious side effect usually necessitating discontinuation of the drug therapy. Because mood disorders preponderated in most patients previously described with this psychosis, 27 patients were empirically treated with lithium carbonate concurrently with corticotropin. In none of the patients treated with lithium did a psychotic reaction occur, although in a comparable group of 44 patients previously treated identically with corticotropin but without lithium, six (14%) became psychotic.

CDP-choline for the treatment of tardive dyskinesia: a small negative series.

Based on the cholinergic-deficiency hypothesis of tardive dyskinesia (TD), we administered cytidine diphosphoryl choline (CDP-Choline) (a naturally occurring biochemical intermediary in the synthesis of phosphatidylcholine), 500 mg twice a day orally, to four women and one man with TD for 2 to 8 weeks in a double-blind, placebo-controlled crossover trial. Although the small sample size provides only limited power to detect a treatment effect, there was no evidence of efficacy, adverse effects, or changes in psychopathology.

Clovoxamine in the treatment of depressed outpatients: a double-blind, parallel-group comparison against amitriptyline and placebo.

In a double-blind, random-assignment, parallel-group trial, outpatients with major depression received either the new antidepressant clovoxamine, the tricyclic amitriptyline, or placebo for 6 weeks. By an "improvement" criterion of 50% or greater improvement in the Hamilton Depression Scale (HAM-D) total score, 88% of clovoxamine completers improved versus 75% with amitriptyline and 43% with placebo; however, due to small numbers, the differences failed to reach statistical significance. Diminished salivary flow was significantly greater with amitriptyline, as were complaints of dry mouth, somnolence, dizziness, and headache. Nausea and vomiting were more common in the clovoxamine-treated group. With amitriptyline, but not with clovoxamine, memory performance declined over a month. However, psychomotor performance was not affected.

Fluoxetine versus trazodone in depressed geriatric patients.

A total of 27 subjects began active treatment in this double-blind study comparing the efficacy and safety of trazodone and fluoxetine in geriatric depressed patients, but only 13 completed 6 weeks on study medication. Both agents were effective according to weekly and endpoint analyses, and there was no evidence of significant effects on blood pressure, pulse, or weight. Separate analysis of patients who had received an adequate trial of medication indicated a trend toward relatively more fluoxetine-treated patients meeting clinical criteria for resolved depression.
