Drug category merged with the mechanism enabling it of action

Amitriptyline is classified as a tricyclic antidepressant. It works by blocking the reuptake of serotonin and noradrenaline in the central nervous system, increasing the levels of these neurotransmitters at nerve synapses. This action can improve mood and, at lower doses, dampen aberrant pain signals and reduce migraine frequency.

Alternate medicines and similar drugs

Treatment choices are individualized. Choice substitute options that prescribers in Australia may consider include:

• Other TCAs: nortriptyline, imipramine, clomipramine, doxepin. Nortriptyline can be better tolerated when anticholinergic effects are a concern.
• SSRIs: sertraline, escitalopram, fluoxetine and citalopram. These are commonly used for depression and may be preferred for some patients.
• SNRIs: venlafaxine, desvenlafaxine and duloxetine. Duloxetine formulation has symptoms for diabetic neuropathy and some chronic pain syndromes.
• NaSSA: mirtazapine may be chosen when insomnia or poor appetite are prominent symptoms.
• Other antidepressants: options such as vortioxetine or agomelatine may be considered based on symptom profile and side effect tolerance.
• Non-antidepressant agents for neuropathic pain include gabapentin and pregabalin. For migraine prevention consider propranolol, candesartan, topiramate or botulinum toxin in selected patients.
