Secondary amine TCAs result from the metabolism of tertiary amine TCAs, during which there is loss of one methyl group on the nitrogen side chain. They include nortriptyline, protriptyline, and desipramine. Secondary amine TCAs are better tolerated than tertiary amine TCAs due to decreased histaminic, cholinergic, and alpha-1 adrenergic. Tricyclic antidepressants work by increasing levels of both serotonin and norepinephrine (a neurotransmitter and hormone known to affect mood) in the brain (3) Just like SNRIs, TCAs work by blocking the reabsorption of serotonin and norepinephrine to increase levels of these neurotransmitters in the brain This is the best online medical lectures site, providing high quality medical and nursing lectures for students across the globe.
