The clinical efficacy of fluvoxamine (DU 23000)--the first selective serotonin re-uptake inhibitor of the new class of 2-aminoethyloximethers of aralkylketones was investigated in endormorphous depressed patients during 5 weeks treatment with mean daily dosages of approximately 150 mg DU 23000. A marked and statistically significant improvement of the overall and detailed psychopathology was noted by means of the Global Clinical Impression and Hamilton Rating Scale as early as in the first week of drug administration. Bipolar patients tended to improve more than unipolar ones, retarded depressions more than agitated ones. An additional anxiolytic medication was occasionally required. The drug was well tolerated. Psychometric and laboratory findings did not show any significant changes. The findings are discussed in the light of the indolamine hypothesis of depression.
Objective and subjective quality of sleep and awakening as well as circadian rhythms in Cortisol, temperature and well-being were investigated in 10 female hospitalized depressed patients diagnosed as major depressive disorders according to RDC criteria before (baseline), during (intervention) and after (recovery) treatment with biologically active or bright light (BL) and were compared with the findings in 10 normals. Polysomnographic evaluation demonstrated in depressed patients an increased sleep latency, decreased total sleep time, attenuated S4 and augmented REM sleep, as well as a shortened REM latency and a statistically significant increased average REM length as compared with normals. BL tended to shorten sleep onset, decrease number of awakenings, increase REM latency and significantly attenuated the average REM length. Subjective sleep quality tended to improve as did the subjective awakening quality after the recovery night. There was, however, a statistically significant improvement of the objetively evaluated quality of awakening and early morning behavior characterized by an improved attention, reaction time and performance in the reaction time task, while concentration and psychomotor activity tended to improve as well. BL effects were also seen in hormonal secretion patterns: circadian Cortisol secretion maxima occurred earlier in depressed patients than in normals before and after BL treatment, while during BL intervention this difference disappeared. Circadian temperature rhythms did not exhibit any significant findings with the exception of an earlier occurring minimum in depressed patients than in normals after treatment. Finally, subjective well-being as rated by means of an analogue scale was significally worse in depressed patients than normals before but not during and after light treatment. The findings are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
