TCAs
Give an example of a tertiary amine and a secondary amine.
What is the difference in side effect profile between tertiary versus secondary amines?
Tertiary amines: amitriptyline, clomipramine, imipramine, doxepin
Secondary amines: nortriptyline, desipramine, protriptyline
(ex. amitriptyline -> nortriptyline)
Tertiary amines have MORE antihistaminic and anticholinergic activity than secondary amines
