Perphenazine plus amitriptyline is indicated for which condition?

• A. Depression with anxiety associated with chronic physical disease
• B. Tourette's Syndrome
• C. Nausea and vomiting
• D. Acute intermittent porphyria

Answer: (A)

The combination of a phenothiazine antipsychotic with a tricyclic antidepressant was historically used to treat severe depression with prominent anxiety, especially when it occurs alongside chronic physical illness. Perphenazine provides calming, antiemetic, and anti-psychotic effects through dopamine blockade, while amitriptyline delivers antidepressant benefits and helps reduce anxiety and somatic symptoms. In patients with depression plus anxiety associated with chronic physical disease, this pairing addresses both mood and anxious/psychosomatic features, making it the best indication among the options. The other conditions—Tourette’s syndrome, nausea and vomiting, and acute intermittent porphyria—are not the primary indications for this fixed-dose combination; they require different treatments or have safety considerations that do not align with this regimen.
