Medical and Biotech [MESH] Definitions
Amitriptyline
Tricyclic antidepressant with anticholinergic and sedative properties. It appears to prevent the re-uptake of norepinephrine and serotonin at nerve terminals, thus potentiating the action of these neurotransmitters. Amitriptyline also appears to antagonize cholinergic and alpha-1 adrenergic responses to bioactive amines.
Paroxetine
A serotonin uptake inhibitor that is effective in the treatment of depression.
Fluoxetine
The first highly specific serotonin uptake inhibitor. It is used as an antidepressant and often has a more acceptable side-effects profile than traditional antidepressants.
Bupropion
A unicyclic, aminoketone antidepressant. The mechanism of its therapeutic actions is not well understood, but it does appear to block dopamine uptake. The hydrochloride is available as an aid to smoking cessation treatment.
Opipramol
A tricyclic antidepressant with actions similar to AMITRIPTYLINE.
