Trends in Prescribing of Selective Serotonin Reuptake Inhibitors and Other Newer Antidepressant Agents in Adult Primary Care.

BACKGROUND: The introduction of selective serotonin reuptake inhibitors (SSRIs) represented a breakthrough in depression treatment due to their safety and ease of use. The purpose of this study was to extend previous work on trends in antidepressant use to include recent data and to provide more detailed analysis of prescribing trends for SSRIs and newer non-SSRI antidepressants, specifically in adult primary care practice. METHOD: Adult primary care visits from the National Ambulatory Medical Care Survey (NAMCS) between 1989 and 2000 were analyzed. Chi-square tests for trend and multivariable logistic regression models were utilized to examine patterns of antidepressant use over time. SSRIs (citalopram, fluoxetine, fluvoxamine, paroxetine, sertraline) and newer non-SSRI antidepressants (bupropion, mirtazapine, nefazodone, venlafaxine) were classified as newer agents. RESULTS: 89,424 adult primary care visits were recorded in the NAMCS during the period studied. Antidepressant use increased in primary care from 2.6% ( approximately 6 million visits) in 1989 to 7.1% ( approximately 20.5 million) in 2000 (p <.001). SSRI and newer non-SSRI use increased linearly from 1989 to 2000 (p <.001), with an adjusted odds ratio for use of 1.27 per year (95% confidence interval = 1.25 to 1.29). The increase in antidepressant use was due to these newer agents (13.5% of all antidepressant use in 1989 to 82.3% in 2000) with each new agent adding to a stable base of previously introduced newer antidepressant agents. CONCLUSIONS: The prevalence of antidepressant use in adult primary care has risen dramatically since 1989, largely reflecting use of newer agents. The detailed pattern of increased use of these medications is striking, with each new agent adding to aggregate use without concomitant decrease in previously introduced newer agents. Such trends reflect more widespread pharmacologic treatment of depressed primary care patients.

[Biological factors and resistance to antidepressive agents].

Concerning depressive disorders, biological factors remain relatively unknown. However, they might first be risk factors for depressive disorders and secondly could decrease the response to antidepressants. We studied hypothyroidism, diabetes and hypothalamic-pituitary-adrenal axis disorders. In terms of neurotransmitters, beta-adrenergic dysfunction may be involved in hypothyroidism and diabetes whereas a serotonergic dysfunction may be involved in hypothalamic-pituitary-adrenal axis disorders.

[New antidepressive agents during pregnancy and lactation. Drug concentration should be monitored and the lowest possible dose administered].

This article presents a literature review on the treatment with new antidepressants during pregnancy and lactation, focusing on possible unwanted effects to the fetus and infant. Most data is available for the selective serotonin reuptake inhibitors, and particularly for fluoxetine. Some information exists for venlafaxine, whereas no published data was found for other new antidepressants such as reboxetine and mirtazapine. In general, treatment with new antidepressants during the first trimester in pregnancy has not been associated with an increased risk for congenital malformations. In contrast, symptoms such as irritability, respiratory distress and muscular hypotonia have been reported in newborns after third trimester exposure. The excretion of new antidepressants in breast milk seems in most cases to be negligible. However, suspected adverse effects have been reported in a few infants. In conclusion, existing data seems to indicate that the positive effects of maternal drug treatment and of lactation to the infant generally outweigh the risks of possible pharmacological effects. Nevertheless, before a new antidepressant is prescribed to a pregnant or lactating woman, an individual risk/benefit-assessment should always be carried out.
