Pharmaceutical Information
Drug Name Amitriptyline hydrochloride
Drug ID BADD_D00119
Description Amitriptyline hydrochloride, also known as _Elavil_, is a tricyclic antidepressant (TCA) with analgesic properties, widely used to treat depression and neuropathic pain [A174658]. It was originally approved by the FDA in 1977 and manufactured by Sandoz [L5308].
Indications and Usage Amitriptyline, a tertiary amine tricyclic antidepressant, is structurally related to both the skeletal muscle relaxant cyclobenzaprine and the thioxanthene antipsychotics such as thiothixene. It is extremely sedating, and thus improvement of sleep patterns can be the first benefit of treatment. Amitriptyline exhibits strong anticholinergic activity, cardiovascular effects including orthostatic hypotension, changes in heart rhythm and conduction, and a lowering of the seizure threshold. As with other antidepressants, several weeks of therapy may be required in order to realize the full clinical benefit of amitriptyline. Although not a labelled indication, amitriptyline is widely used in the management of chronic nonmalignant pain (e.g., post-herpetic neuralgia, fibromyalgia).
