A double‐blind comparison of citalopram (Lu 10–171) and amitriptyline in depressed patients

Abstract

ABSTRACT— In a controlled, clinical, multicentre trial comprising a total of 43 patients (17 men and 26 women) citalopram was compared double‐blindly with amitriptyline. Nineteen patients of each group were classified as endogenously depressed, whereas four patients of the citalopram group and one of the amitriptyline group were classified as non‐endogenously depressed. The patients were seriously ill with a high frequency of previous depressive episodes and of mental disorders among their closest relatives. Thirteen of the patients in either group had received antidepressants without satisfactory effect before entry into the trial. Each patient was treated for a period of at least 3 weeks with daily citalopram doses of 30–60 mg or daily amitriptyline doses of 75–225 mg. A statistically significant reduction of MADRS scores (total scores as well as each of the 10 individual items) was recorded in both groups. The only difference between the groups was a trend towards a better effect on sleep disturbances in the amitriptyline group. Side‐effects were recorded more frequently in the amitriptyline group than in the citalopram group, global assessment of side effects being significantly different in favour of citalopram. It is concluded that citalopram is an effective and safe drug in the treatment of endogenous depression ‐ probably as efficacious as amitriptyline, but with fewer side effects.
