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.

Effects of protein and carbohydrate meals on mood and performance: interactions with sex and age.

Normal adult subjects (n = 184) consumed a high-protein or high-carbohydrate meal. Two hours later their mood and performance were tested. The effects of meal composition on mood were different for men and women, and for older and younger subjects. Females, but not males, reported greater sleepiness after a carbohydrate as opposed to a protein meal. Male subjects, but not females, reported greater calmness after a carbohydrate as opposed to a protein meal. Older subjects responded differently to meals depending upon the time of day when these were consumed. When meals were eaten for breakfast (but not for lunch) individuals 40 yr of age or older felt more tense and less calm after a protein than after a carbohydrate meal. Although older subjects reported subjective discomfort after a morning protein meal, they displayed objective performance impairments after a carbohydrate lunch. Subjects 40 yr of age or older were impaired on a test of sustained selective attention (dichotic shadowing) after consuming a high-carbohydrate lunch. The shadowing impairment after carbohydrate consumption was as pronounced without distraction as with distraction and resulted mostly from increased omission errors. Our findings suggest negative effects on concentration when older subjects consume a high-carbohydrate, low-protein lunch. These negative effects of carbohydrate consumption appear to arise predominantly from lapses of attention rather than from intrusion of distractors.
