Antidepressant paroxetine linked to higher rate of suicide attempts in adults

23.08.2005


Adult patients taking the antidepressant drug paroxetine are at higher risk of attempting to commit suicide than those not taking medication. A new analysis, published in BMC Medicine, of previous clinical data on paroxetine use adds the antidepressant to the list of Selective Serotonin Reuptake Inhibitors (SSRIs) that have been shown to increase suicidal tendencies in adult patients with depression.



Ivar Aursnes and colleagues from the University of Oslo, Norway, reanalysed data from 16 selected paroxetine trials. In the trials, patients diagnosed with depression had been randomly given either paroxetine or a placebo drug. Neither the participants nor the researchers conducting the initial studies knew what the participants had been given. Aursnes et al. did a new statistical analysis of the results of these studies, to evaluate the incidence of suicide attempts in both groups. In their analysis, they took into account the amount of time the participants had been exposed to paroxetine. Their results show that there were seven suicide attempts in the group on paroxetine, and only one among the patients on placebo.

Paroxetine has been shown to increase suicidal attempt rates in children and teenagers, but previous studies have failed to reach a conclusion as regards the effects of the drug on suicide attempt rates in adult patients. Gunnell et al., in the February 19th 2005 issue of the BMJ, warned doctors about an increased risk of suicidal behaviour in patients treated with SSRIs. Their conclusion was based on analyses of clinical data submitted by the pharmaceutical companies that produce SSRIs to the Medicine and Healthcare products Regulatory Agency. But Gunnell et al.’s study had not properly included data on paroxetine.


Aursnes et al. conclude that “the recommendation of restrictions in the use of paroxetine in children and adolescents conveyed by regulatory agencies lately should include usage in adults”. They confirm that all SSRIs increase suicidal tendencies in depressed adults, “the data strongly suggest that the use of SSRIs are connected with increased intensity per year of suicidal attempts”.

Im Focus: Abrupt motion sharpens x-ray pulses

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.

A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...

Im Focus: Physicists Design Ultrafocused Pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
