Jf. Karp et al., IMIPRAMINE AND SEXUAL DYSFUNCTION DURING THE LONG-TERM TREATMENT OF RECURRENT DEPRESSION, Neuropsychopharmacology, 11(1), 1994, pp. 21-27
Ninety patients in the maintenance therapy phase of the Pittsburgh Stu
dy of Maintenance Therapies in Recurrent Depression (Frank et al., 199
0) were studied to determine possible relationships between the type o
f therapy (imipramine versus no drug) and the level of sexual function
ing. The level of sexual functioning was determined by a composite sub
scale score of the Social Adjustment Scale which assessed (1) current
level of enjoyment and interest in sex; (2) change in interest; (3) cu
rrent frequency of sexual intercourse; (4) change in frequency; and (5
) pain and/or difficulty reaching orgasm. Loss of libido was assessed
by both the Hamilton Rating Scale for Depression and the SCL-90. Logis
tic regression analysis revealed no relationship between treatment wit
h active imipramine and sexual functioning for the total group, or for
females alone. Analysis of males alone revealed a decreased interest
in sex among those treated with imipramine, but no significant differe
nces in frequency or problems. The implications for maintenance pharma
cotherapy and the cost/benefit ratio of unacceptable side effects vers
us drug efficacy are discussed.
