Has anybody used Zoloft (sertraline) for anhedonia (lack of pleasure)?? According to this study it could maybe help. But I’m skeptical

Sequential improvement of anxiety, depression and anhedonia with sertraline treatment in patients with major depression.

P Boyer, JP Tassin, B Falissart and S Troy, Journal of clinical pharmacy and therapeutics, Oct 2000

To establish the therapeutic effect profile of sertraline in major depression. It was hypothesized that the antidepressant effect of sertraline showed three phases: Phase 1 where improvements in anxiety are most pronounced; Phase 2 where the greatest improvements are in depressive symptoms; and Phase 3 where the symptoms of anhedonia show the most improvement. To test this hypothesis, an 8-week, open-label study was conducted.Patients with a major depressive episode (DSM-IV) and a score > or = 24 on the 17-item HAM-D were enrolled and treated with sertraline 50-150 mg/day. The three symptomatic clusters, anxiety, depression and hedonia, were defined a priori using the Inventory of Depressive Symptomatology-Clinician rated (IDS-C). Periods of interest were: Days 0-7 for anxiety, Days 7-21 for depression and Days 21-56 for anhedonia. Raters were blinded as to the constitution of the clusters and periods.140 patients were recruited. Improvement in the anxiety cluster of the IDS-C was greatest during Days 0-7, whereas over Days 7-21 most improvement was observed in the depression cluster and the greatest improvement in the hedonic cluster occurred during Days 21-56.These preliminary results are consistent with the hypothesis that the therapeutic effects of sertraline occur in a sequential manner. The symptoms of anxiety improved first, followed by depression and then anhedonia.

Repeated treatment with antidepressants enhances dopamine D1 receptor gene expression in the rat brain.

M Huzarska, M Zieliński and ZS Herman, European journal of pharmacology, Feb 27 2006

Many pharmacological investigations have demonstrated that antidepressant agents profoundly affect serotonergic and noradrenergic neurotransmission. The molecular mechanisms by which these drugs exert their therapeutic action have not been clearly established. In our study, the possibility that antidepressant drug action is associated with dopamine neurotransmission was examined. To this end, the effect of 21-day treatment with 10 mg/kg of amitryptyline, mirtazapine and sertraline on the striatal and nucleus accumbens dopamine receptors was verified. The striatum and nucleus accumbens tissues were dissected 24 h after the last dose of the drug and total RNA was isolated. The expression of dopamine D1 to dopamine D5 receptors using reverse-transcriptase polymerase chain reaction (RT-PCR) procedure was compared to the glyceraldehyde-3-phosphate-dehydrogenase (GAPDH) as constitutive gene activation internal control. Lab Works UV program has analyzed the mean optical density values of RT-PCR products. Statistical comparison of relative optical densities by a one-way analysis of variance (ANOVA) followed by Dunnett's test was performed. Despite their different pharmacological profiles, all three above-presented antidepressants significantly increased dopamine D(1) mRNA content. Our findings indicate that repeated antidepressant administration triggers induction of the brain dopaminergic receptors which is correlated with neuroadaptation of the brain dopaminergic pathway.
