Selective serotonin reuptake inhibitor - Wikipedia. Selective serotonin reuptake inhibitors (SSRIs), also known as serotonin- specific reuptake inhibitors or serotonergic antidepressants. They have varying degrees of selectivity for the other monoamine transporters, with pure SSRIs having only weak affinity for the norepinephrine and dopamine transporters. SSRIs are the most widely prescribed antidepressants in many countries. SSRIs are frequently prescribed for anxiety disorders, such as social anxiety disorder, panic disorders, obsessive–compulsive disorder (OCD), eating disorders, chronic pain and occasionally, for posttraumatic stress disorder (PTSD).

They are also frequently used to treat depersonalization disorder, although generally with poor results. The authors attributed the relationship between severity and efficacy to a reduction of the placebo effect in severely depressed patients, rather than an increase in the effect of the medication. FDA published a systematic review of all antidepressant maintenance trials submitted to the agency between 1. The authors concluded that maintenance treatment reduced the risk of relapse by 5. Furthermore, SSRIs versus placebo significantly increase the risk of both serious and non- serious adverse events. Our results show that the harmful effects of SSRIs versus placebo for major depressive disorder seem to outweigh any potentially small beneficial effects. GAD is a common disorder of which the central feature is excessive worry about a number of different events.
Key symptoms include excessive anxiety about multiple events and issues, and difficulty controlling worrisome thoughts that persists for at least 6 months. Antidepressants provide a modest- to- moderate reduction in anxiety in GAD. In children, SSRIs can be considered a second line therapy in those with moderate- to- severe impairment, with close monitoring for psychiatric adverse effects. Long- term efficacy remains poorly characterized. Similar recommendations apply to binge eating disorder. Those from the American Psychiatric Association note that SSRIs confer no advantage regarding weight gain, but that they may be used for the treatment of co- existing depressive, anxiety, or obsessive- compulsive disorders. A recent meta- analysis of randomized, controlled clinical trials found a statistically significant effect of SSRIs on dependence, neurological deficit, depression, and anxiety. There was no statistically significant effect on death, motor deficits, or cognition. Chronic administration is more efficacious than on demand use. However, certain types of adverse effects are found broadly among most if not all members of this class: Sexual dysfunction. The range of possible mechanisms includes (1) nonspecific neurological effects (e. Some authors have suggested electrocardiographic monitoring in patients with severe pre- existing cardiovascular disease who are taking SSRIs. Paroxetine may produce discontinuation- related symptoms at a greater rate than other SSRIs, though qualitatively similar effects have been reported for all SSRIs. One strategy for minimizing SSRI discontinuation symptoms is to switch the patient to fluoxetine and then taper and discontinue the fluoxetine. Food and Drug Administration (FDA) analysis of clinical trials on children with major depressive disorder found statistically significant increases of the risks of . A 2. 01. 2 Cochrane review found that at six to nine months, suicidal ideation remained higher in children treated with antidepressants compared to those treated with psychological therapy.

No difference risk of suicide attempts was detected between SSRIs versus tricyclic antidepressants. The decline is particularly striking for women who, compared with men, seek more help for depression. Recent clinical data on large samples in the US too have revealed a protective effect of antidepressant against suicide. However, the observational studies suggest that SSRIs did not increase suicide risk more than older antidepressants. The researchers stated that if SSRIs increase suicide risk in some patients, the number of additional deaths is very small because ecological studies have generally found that suicide mortality has declined (or at least not increased) as SSRI use has increased. Among adults younger than 2. For adults between 2. For adults older than 6. SSRI's seem to reduce the risk of both suicidal behavior. As depression is independently associated with negative pregnancy outcomes, determining the extent to which observed associations between antidepressant use and specific adverse outcomes reflects a causative relationship has been difficult in some cases. However, the medical literature on the safety of SSRIs has determined that some SSRIs like Sertraline and Paroxetine are considered safe for breastfeeding. These syndromes are short- lived, but insufficient long- term data is available to determine whether there are long- term effects. Newborn babies with PPHN have high pressure in their lung blood vessels and are not able to get enough oxygen into their bloodstream. About 1 to 2 babies per 1. U. S. It is associated with about a 2. This relative safety is supported both by case series and studies of deaths per numbers of prescriptions. The most commonly reported severe effect following SSRI overdose is serotonin syndrome; serotonin toxicity is usually associated with very high overdoses or multiple drug ingestion. Most of these arise from the fact that every SSRI has the ability to inhibit certain P4. The serotonergicserotonin- norepinephrine reuptake inhibitors and serotonin- norepinephrine- dopamine reuptake inhibitors are also commonly used as antidepressants. Mechanism of action. The presynaptic cell that sends the information releases neurotransmitters including serotonin into that gap. The neurotransmitters are then recognized by receptors on the surface of the recipient postsynaptic cell, which upon this stimulation, in turn, relays the signal. About 1. 0% of the neurotransmitters are lost in this process; the other 9. SSRIs inhibit the reuptake of serotonin. As a result, the serotonin stays in the synaptic gap longer than it normally would, and may repeatedly stimulate the receptors of the recipient cell. In the short run, this leads to an increase in signaling across synapses in which serotonin serves as the primary neurotransmitter. On chronic dosing, the increased occupancy of post- synaptic serotonin receptors signals the pre- synaptic neuron to synthesize and release less serotonin. Serotonin levels within the synapse drop, then rise again, ultimately leading to downregulation of post- synaptic serotonin receptors. Further, they have fewer and milder side effects. Tricyclic antidepressants also have a higher risk of serious cardiovascular side effects, which SSRIs lack. SSRIs act on signal pathways such as c. AMP (Cyclic AMP) on the postsynaptic neuronal cell, which leads to the release of Brain- Derived Neurotrophic Factor (BDNF). BDNF enhances the growth and survival of cortical neurons and synapses.

In fact, researchers say that diet and exercise are not enough to help diabetics lose weight and that drug intervention is needed that is effective, safe and can be taken in conjunction with blood- sugar medications for treating their diabetes. This week, researchers announce in a free online journal article published in the journal Obesity that the diet pill lorcaserin has demonstrated significant weight loss in patients with Type 2 diabetes. Lorcaserin is a serotonin receptor angonist that works specifically on appetite signals in the brain and has been shown in previous studies—with otherwise healthy obese individuals—to cause significant weight loss. Encouraged by the previous weight loss findings with lorcaserin, researchers from a variety of academic institutions and members of The Obesity Society (TOS), worked together to determine whether or not lorcaserin is safe and effective in the treatment of overweight patients with Type 2 diabetes. In a study titled BLOOM- DM (Behavioral Modification and Lorcaserin for Obesity and Overweight Management in Diabetes Mellitus), researchers recruited 6. The participants were divided into 3 groups with one group receiving 1. All patients continued with their metformin and SFU (sulfonylurea) anti- diabetes drugs during the trial. Metformin is an anti- diabetes drug that lowers blood sugar levels, and has been found to cause slight weight loss. SFU is a drug that induces the pancreas to secrete additional insulin. All participants also engaged in a lifestyle modification weight loss program during the study. After one year, the researchers found that patients with Type 2 diabetes who took either the 1.
