Serotonin syndrome (SS) is a group of symptoms that may occur with the use of certain serotonergic medications or drugs. [1] The symptoms can range from mild to severe, and are potentially fatal. [ 4 ] [ 5 ] [ 2 ] Symptoms in mild cases include high blood pressure and a fast heart rate ; usually without a fever . [ 2 ]
A serious, but rare, side effect of SNRIs is serotonin syndrome, which is caused by an excess of serotonin in the body. Serotonin syndrome can be caused by taking multiple serotonergic drugs, such as SSRIs or SNRIs. Other drugs that contribute to serotonin syndrome include MAO inhibitors, linezolid, tedizolid, methylene blue, procarbazine ...
For this reason, many users carry an MAOI-card, which lets emergency medical personnel know what drugs to avoid (e.g. adrenaline [epinephrine] dosage should be reduced by 75%, and duration is extended). [25] Tryptophan supplements can be consumed with MAOIs, but can result in transient serotonin syndrome. [30]
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
Serotonin–norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine (Effexor), its active metabolite desvenlafaxine (Pristiq), and duloxetine (Cymbalta) prevent the reuptake of both serotonin and norepinephrine, however their efficacy appears to be only marginally greater than the SSRIs.
A serotonin releasing agent (SRA) is a type of drug that induces the release of serotonin into the neuronal synaptic cleft. A selective serotonin releasing agent (SSRA) is an SRA with less significant or no efficacy in producing neurotransmitter efflux at other types of monoamine neurons, including dopamine and norepinephrine neurons. [1]
Side effects in dogs and cats include hypersalivation, diarrhea, loss of appetite, and vomiting. [12] [16] Eight percent of dogs taking maropitant at doses meant to prevent motion sickness vomited right after, likely due to the local effects maropitant had on the gastrointestinal tract. Small amounts of food beforehand can prevent such post ...
Of the serotonin receptors, it is an especially potent antagonist of the 5-HT 2 receptors. This is thought to underlie its effectiveness in the treatment of serotonin syndrome. [30] However, it is possible that blockade of 5-HT 1 receptors may also contribute to its effectiveness in serotonin syndrome. [31]
