I P-12-19! P Poster Presentations efficacy and CHESS for tolerance. ANOYA was used for comparison of quantitative variables and X 2 or Fisher exact test for qualitative variables: - 87 patients completed the study in the sertraline group and 77 in the ftuoxetine group with: - 10 (8.5%) patients dropped out for side effect in the sertraline group and 12 (10%) in the ftuoxetine group. - At six month improvement over baseline was significant for depres- sion (Hamilton and HAD p < 0.001), anxiety (COYI p < 0.001), sleep (Leeds p < 0.001) and on most of the sub-scores, as well as on the total score of the SIP (quality of life) scale (p < 0.001). The magnitude of change on depression anxiety, sleep and quality of life was larger with sertraline than with f1uoxetine but none of these differences reached statistical significance. Both treatment were well tolerated with no significant difference between treatment. I P-12-171 Psychotropic Comedication and Adverse Event Rates. Results from a Fluoxetine Drug Surveillance Study RW. Dittmann I, M. Linden 2, M. Osterheider 3. I Univ. of Hamburg; Medical Dep., Lilly Germany, Bad Homburg, Germany; 2 Dep. of Psychiatry, Univ. of Berlin, Germany; 3 Dep. of Psychiatry, Paderborn, Germany Introduction: Studies with the SSRI Fluoxetine (Fix) under naturalistic conditions have been conducted in'Germany (1990 to 1993; N > 19.000). We report on 3.158 pats. treated by psychiatrists. Objective: comparison of adverse event (AE) rates in pats. treated with Fix monotherapy (Flx- mono, N = 1.571) vs. in those with psychotropic (l drug) comedication (PD; N = 737). Hypothesis: higher rate of AEs in comedicated pats. because of the well-known interactions between Fix and tricyclic antide- pressant and antipsychotic drugs (Cyt P450 2D6), and with tranquilizers as well. Methods: Based on German scientific recommendations for drug surveillance studies, data collection comprised: pal. characteristics, diag- noses. medication, comedication, efficacy, AEs (physicians' information). This analysis focussed on pat. characteristics and AE rates. Results: Compared to Fix-mono the PD group showed: higher age (p < 0.001), more pats. with endogenous and fewer with "neurotic" depression (p < 0.(01), with remittant or chronic course (p < 0.(01); more COl severity (p < 0.001), higher Fix dose (p < 0.05); slightly more overall AE rates (PD: 26.7 vs. 23.5%), "serious" and "routine" (p ::: 0.10). Single AEs matched the known Flx-AE-spectrum (nervousness, nausea < 7%, others < 2%). Group differences were mainly accounted for by pats. with one an- tipsychotic co-medication (N = 128), e.g., more pats. with AEs (31.3 vs. 23.5%, p = 0.06), "routine" and "serious". AE spectrum as known, EPS: tremor 1.6%, akathisia 0.8%. Conclusion: Findings suggest that, under naturalistic conditions, comcdication of FIx with these compounds does not basically change the favourable risklbenefit ratio of FIx use. I P-12-181 Serotonergic (Fluoxetine) Versus Noradrenergic (Maprotiline) Antidepressants and Suicidality M. Jakovljevic I, D. Vujic 2, N. Henigsberg 3. I University Psychiatric Clinic Zagreb, Croatia; 2 Lek Pharmaceutical and Chemical Company, Ljubljana, Slovenia Depression is commonly associated with suicidal thoughts and be- haviour. Effect of antidepressants on suicidality is of great importance for outcome of antidepressant treatment.There are reports that selective serotonin reuptake inhibitors (SSRl) reduce suicidal ideas faster than other antidepressants what is in line findings of correlation between low central serotonin concentration and suicidal behaviour. On the other hand some authors reported the use of f1uoxetine (SSRI) might lead to the emergence or worsening of suicidal ideation, while the others reported that maprotiline (a noradrenaline uptake inhibitor) was associated greater incidence of suicidal acts. To examine the relation between suicidality and different types of antidepressant drugs, the, data week double blind, prospective, multicentre and multinational comparing ftuoxetine with maprotiline were analysed. 125 The database analysed comprised 98 patients of both sex with de- pressive episode, aged 40-65 years. 50 patients were treated ftuoxetine (20-40 mg/d) and 48 with maprotiline (75-150 mg/d); The global antide- pressant efficacy was comparable. A differentiated a? does not show any difference in risk of suicidal acts between depressed patients treated with f1uoxetine and those treated with maprotiline. Analysis also failed to find difference in beneficial effect on suicidality between these two drugs. Outcomes Including Withdrawal Phenomena Detected from a Naturalistic Comparison of Fluoxetine and Paroxetine Used in the Treatment of Affective Disorders in Patients with Learning Disabilities S. Bhaumik, H.J. Wildgust. Frith Hospital, Leicester, U.K. Randomised controlled clinical trials suggest that the efficacy and side ef- fects associated with f1uoxetine and paroxetine are verysimilar. However, naturalistic observations by Donaghue & Sclar suggest that in clinical practice there are differences which lead to higher costs associated with paroxetine. Similarly, randomised control trials have not shown with- drawal phenomena to be associated with SSRIs and they commented thar it occurred more commonly with paroxetine. However, the Committee of Safety of Medicine have received a number of reports of withdrawal phenomena for SSRIs. Fava noted that this phenomena occurred in pa- tients who had had long-term exposure to paroxetine and sertraline and this may explain why randomised controlled trials have failed to pick up these events. We have, therefore, computed a very careful retrospective casenote analysis of the usage of both f1uoxetine and paroxetine inadult patients with learning disabilities from Leicester, UK, who have received treatment for depression/affective disorders in a three year period. In the reported data on efficacy, side-effects and withdrawal phenomenon our study shows that, in clinical practice, both ftuoxetine and paroxetine have similar efficacy and side effect pattern but a higher discontinuation rate was noted with paroxetine (8.8% f1uoxctine vs. 18% for paroxetine). For fluoxetine there was no reported withdrawal phenomena but 42% of the patients treated with paroxetine experienced withdrawal phenomena. The symptoms of antidepressant withdrawal is not documented in patients with learning disabilities and we have reviewed differences in its pre- sentation from the general population. The value of this study is in its accurate reflection of clinical practice and, arguably, more effective anal- ysis of outcome (including drop-out rates, side-effects and withdrawal phenomena) than conventional clinical trial data.
