Unintentional amitriptyline overdose leading to coma and cardiac conduction impairment in an older adult: A case report.
Article in SAGE open medical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Elderly patients are particularly vulnerable to look-alike/sound-alike medication errors due to physiological differences that alter medication pharmacokinetics and pharmacodynamics. This report presents the case of a 70-year-old woman admitted to the emergency department in an unconscious state. The information provided by the patient's family suggested a potential unintentional amitriptyline overdose due to confusion with berberine-a plant-derived over-the-counter antidiarrheal medication of similar appearance and packaging. Examination of the remaining amitriptyline tablets indicated the patient had likely consumed 19 tablets of 25 mg amitriptyline. This suspicion was supported by an electrocardiogram showing QRS widening to 110 ms and tachycardia. Following serum alkalization therapy with sodium bicarbonate, the patient's consciousness improved, her heart rate normalized, and QRS duration was shortened. This case underscores the importance of involving healthcare providers and family members in implementing robust safety measures to prevent unintentional medication errors caused by look-alike/sound-alike medications, particularly among older adults.
