Mirtazapine is a very strong H 1 receptor antagonist and, as a result, it can cause powerful sedative and hypnotic effects. [11] A single 15 mg dose of mirtazapine to healthy volunteers has been found to result in over 80% occupancy of the H 1 receptor and to induce intense sleepiness. [92]
Chemical structure of the prototypical NaSSA mirtazapine (original brand name Remeron). Noradrenergic and specific serotonergic antidepressants (NaSSAs) are a class of psychiatric drugs used primarily as antidepressants. [1]
Besides mirtazapine, they also block the α 1-adrenergic receptor [citation needed]. Conversely, whereas TCAs have relatively low affinity for the α 2 -adrenergic receptor , mianserin and mirtazapine potently antagonize this receptor, and this action is thought to be involved in their antidepressant effects [ citation needed ] .
An atypical antidepressant is any antidepressant medication that acts in a manner that is different from that of most other antidepressants. Atypical antidepressants include agomelatine, bupropion, iprindole, mianserin, mirtazapine, nefazodone, opipramol, tianeptine, and trazodone.
Changes in appetite or weight are common among antidepressants but are largely drug-dependent and related to which neurotransmitters they affect. Mirtazapine and paroxetine, for example, may be associated with weight gain and/or increased appetite, [178] [179] [180] while others (such as bupropion and venlafaxine) achieve the opposite effect ...
Niaprazine (Nopron) – a drug related to this group but does not inhibit the reuptake of serotonin or the other monoamines. Medifoxamine (Clédial, Gerdaxyl) – could perhaps technically be said to belong to this group, as it is a serotonin–dopamine reuptake inhibitor and 5-HT 2A and 5-HT 2C receptor antagonist , but not grouped as such.
Vitamin D is a unique nutrient in that it comes from the food we eat and is a hormone that our bodies make. The fat-soluble vitamin has a slew of important functions and health benefits, from ...
[8] [1] Unlike low-dose mirtazapine, the half life (10 hours) is short enough that next-day sedation may be manageable, however, for people with CYP2D6 polymorphisms, which constitute a sizable fraction of the population, the half-life is expected to be quite a bit longer. Merck researchers claimed that the incidence of next-day sedation was ...
