An eleven item clinician-administered Mania Rating Scale (MRS) is introduced, and its reliability, validity and sensitivity are examined. There was a high correlation between the scores of two independent clinicians on both the total score (0.93) and the individual item scores (0.66 to 0.92). The MRS score correlated highly with an independent global(More)
The Zung Self-rating Depression Scale (ZSDS) correlated well (0.69) with the treating physician's global rating in 26 depressed out-patients during the six weeks of treatment with a tricyclic anti-depressant. In a larger sample of 41 patients, a high correlation was found between the ZSDS and the Hamilton Rating Scale. The sensitivity of the ZSDS was found(More)
Forty-one depressed outpatients were treated for six weeks after random assignment to amitriptyline hydrochloride (N = 22) or nortriptyline hydrochloride (N = 19). On a mean daily dose of 119 mg, amitriptyline-treated patients had a mean tricyclic level (amitriptyline plus nortriptyline) of 120 ng/ml. Nortriptyline-treated patients on a mean dose of 117(More)
Forty consecutively hospitalized patients who had overdosed primarily with a tricyclic antidepressant (TCA) were observed until discharge. The severity of the overdose was documented by serial measurements of plasma TCA levels. Nineteen of the patients became comatose, 16 required supportive respiration, and 2 died. Individual symptoms in the 13 patients(More)
In 26 depressed patients, a high correlation (0-89) was found between the Hamilton score and a psychiatrist's global rating and between the change (0-68) in these ratings during treatment. The Hamilton scale was able to differentiate at the o-01 level four degrees of severity based on the global rating. Limiting the range of severity measured was found to(More)
Forty patients ingesting tricyclic antidepressant (TAD) overdoses were studied as a pharmacologic model to determine whether total tricyclic antidepressant plasma levels correlated with major adverse effects and electrocardiographic findings. Maximum TAD plasma levels were higher in patients who died (p less than 0.025) or had cardiac arrest (p less than(More)
Eighteen depressed outpatients were treated for 6 wk with amitriptyline. Clinical improvement was monitored using the Hamilton Depression Rating Scale administered by two psychiatrists blind to the tricyclic used for treatment, dosage, and plasma levels. Amitriptyline and its desmethyl metabolite, notriptyline, were assayed twice weekly by gas(More)
Eighteen depressed outpatients were treated for 6 wk with a mean daily dose of 121 mg of nortriptyline. The mean plasma level was 138 ng/ml during treatment. Therapeutic response was monitored by the Zung Self-Rating Depression Scale and the Hamilton Depression Scale administrered by two psychiatrists blind to the tricyclic used, dose, and plasma levels.(More)
