'Elavil' is a trademarked brand name created for the drug amitriptyline. The name does not have a traditional etymology from older languages, but was likely constructed to sound positive and uplifting.

'Elavil' was introduced as a brand name for amitriptyline in the mid-20th century and has been used in medical contexts since then.

Initially, 'Elavil' referred specifically to the branded medication, and this meaning has remained unchanged.
