SNRIs are another class of modern antidepressants. Common SNRIs include Cymbalta (duloxetine), Effexor XR (venlafaxine) and Pristiq (desvenlafaxine). Tricyclic antidepressants (TCAs). Tricyclic ...
Studies have shown that SNRIs as well as SSRIs have significant anti-inflammatory action on microglia [55] in addition to their effect on serotonin and norepinephrine levels. As such, it is possible that an additional mechanism of these drugs that acts in combination with the previously understood mechanism exist.
This is a complete list of clinically approved prescription antidepressants throughout the world, as well as clinically approved prescription drugs used to augment antidepressants or mood stabilizers, by pharmacological and/or structural classification. Chemical/generic names are listed first, with brand names in parentheses.
Effexor and Effexor XR (venlafaxine) – an antidepressant of the SNRI class Elavil ( amitriptyline ) – a tricyclic antidepressant used as a first-line treatment for neuropathic pain Eurodin , Prosom ( estazolam ) – a benzodiazepine derivative with anxiolytic , anticonvulsant , hypnotic , sedative and skeletal muscle relaxant properties ...
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
Desvenlafaxine is a synthetic form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). When most normal metabolizers take venlafaxine, approximately 70% of the dose is metabolized into desvenlafaxine, so the effects of the two drugs are expected to be very similar. [18]
To date, a great number of potent and selective and mixed norepinephrine reuptake inhibitors (NRIs) have been marketed as antidepressants. [11] The first commercially available selective norepinephrine reuptake inhibitor (sNRI) was reboxetine (Edronax) and was developed as a first-line therapy for major depressive disorder. [29]
The pharmacology of antidepressants is not entirely clear.. The earliest and probably most widely accepted scientific theory of antidepressant action is the monoamine hypothesis (which can be traced back to the 1950s), which states that depression is due to an imbalance (most often a deficiency) of the monoamine neurotransmitters (namely serotonin, norepinephrine and dopamine).
