He added: "Our compound is 10 times better than Cymbalta at inhibiting the re-uptake of norepinephine and comes close to the holy grail of a perfectly balanced antidepressant," White said.

Some antidepressants - particularly SSRIs (selective serotonin re-uptake inhibitors) such as Prozac - interfere with sex drive in 30 to 60 per cent of cases.

The pill of choice these days is what is known as an SSRI, a selective serotonin re-uptake inhibitor, which maximises the use of the feel-good chemical serotonin within our brains.

What are Selective Serotonin Re-uptake Inhibitors (SSRIs)?

The findings support the idea that venlafaxine's serotonin-norepinephrine reuptake inhibition--a dual mechanism of action that kicks in at high doses--is superior to the selective serotonin re-uptake inhibition of paroxetine in the treatment of depression, he added.

PHILADELPHIA -- A growing body of evidence emerging from double-blind trials is confirming the safety and efficacy of selective serotonin re-uptake inhibitors for major depression in children and adolescents.

Prozac (fluoxetine chlorohydrate) is one of a variety of antidepressants known as selective serotonin re-uptake inhibitors (SSRIs) introduced at the end of the 1980s.

Although it said young adults should be closely monitored if prescribed, the Committee on Safety of Medicines, which carried out the safety review, could find no clear increased risk of suicide associated with Seroxat and other selective serotonin re-uptake inhibitors (SSRIs) than with other anti-depressants.

They believe the selective serotonin re-uptake inhibitor (SSRI) drug interferes with a critical stage of brain development, setting the animals up for emotional disorders later in life.

Prozac, and other selective serotonin re-uptake inhibitors (SSRIs), are thought to increase the risk of gastrointestinal bleeding, nosebleeds and other haemorrhages.

Escitalopram, a selective serotonin re-uptake inhibitor (SSRI) derived from a single isomer that is the active component in the SSRI citalopram, recently won approval by the Food and Drug Administration for the treatment of major depressive disorder.

Damage to the axons would not only affect serotonin re-uptake, but also its release.

* Strong evidence-tricyclics (amitriptyline); dual re-uptake inhibitors (SNRI/NSRI-venlafaxine, duloxetine, milnacipran); alpha-2-delta ligands (pregabalin, gabapentin)

She is now warning others of the dangers of becoming addicted to prescription drugs such as the new anti-depressants Selective Serotonin Re-uptake Inhibitors (SSRIs) saying the side effects may not be known until it is too late.

The Medicines and Healthcare Products Regulatory Agency (MHRA) yesterday told doctors they can only prescribe one of these selective serotonin re-uptake inhibitors to children - Prozac, which is also known as fluoxetine.
