The pharmacoeconomics of venlafaxine in depression.
The prevalence of depression and the high costs associated with its management have heightened interest in pharmacoeconomic evaluation of drug treatment, especially the use of selective serotonin reuptake inhibitors (SSRIs) and the serotonin-norepinephrine reuptake inhibitor venlafaxine. A number of studies of venlafaxine in both inpatient and outpatient settings have revealed that extended-release venlafaxine has a lower expected cost than comparable treatment with SSRIs and tricyclic antidepressants (TCAs). When the relative cost effectiveness of immediate-release venlafaxine, SSRIs, and TCAs was assessed in the treatment of major depressive disorder in 10 countries, venlafaxine yielded a lower than expected cost compared with SSRIs and TCAs in all but 1 country. In comparing healthcare expenditures for depressed patients with and without anxiety, there was a pharmacoeconomic benefit to both immediate- or extended-release venlafaxine, regardless of the presence or absence of comorbid anxiety. A review of computerized administrative claims data from 9 US healthcare plans on resource use and the cost of venlafaxine instead of TCAs after switching from an SSRI showed that overall costs did not vary markedly between venlafaxine and TCAs. This led to the conclusion that although therapy with venlafaxine is more costly than TCA therapy, this increase may be offset by lower costs of other medical services. Such findings have enormous potential ramifications for practicing physicians in terms of venlafaxine's superior remission rate, lower likelihood of relapse, loss of fewer patients to adverse events or lack of efficacy, and flexibility in dosing that enables titration to achieve an optimal response.
