Our finding of a link between serotonergic activation and behaviours in expectation of future reward has important medical implications, as it may explain the effectiveness of serotonin-enhancing drugs for impulsive behaviours (Grant & Potenza, 2004).
The effectiveness of selective serotonin reuptake inhibitors (SSRIs) as antidepressants strongly suggests that serotonin transmitter pathways are involved in illnesses such as depression and anxiety but little is known about the biology of the chemical.
For example, a review, [ 5] of 122 recently published RCTs that evaluated the effectiveness of selective serotonin reuptake inhibitors (SSRI) as first-line management strategy for depression found that only one (0.8%) paper described randomization adequately.
In particular, in view of current anxieties about the potential hazards of using antidepressants in children, 10 clinical trials of the effectiveness of specific serotonin reuptake inhibitors, are especially urgent.
A number of serotonin receptors mediate the effects of serotonin.
It does this by boosting the effectiveness of molecules called serotonin and norepinephrine, which nerve cells use to communicate.
The primary objective of the study is to measure the effectiveness of a selective serotonin reuptake inhibitor (SSRI) in the treatment of depression in a patient population with comorbid substance dependence.
The THREAD (THREshold for AntiDepressants) study is a multi-centre randomised controlled trial designed to determine the clinical and cost effectiveness of a selective serotonin reuptake inhibitor (SSRI) plus general practitioner (GP) supportive care, versus supportive care alone, for mild to moderate depression in primary care.
In women with depression around or following menopause, the effectiveness of treatment with selective serotonin reuptake inhibitors (SSRIs) is enhanced by simultaneous administration of estrogen,[ 63] and doses of estrogen alone are effective at treating premenstrual, postpartum, and perimenopausal depression, especially for depression linked to aberrant expression of 5HT2A receptors [ 25, 66].
