Unrecognised long-lasting tramadol-induced delirium in two elderly patients. A case report
Abstract:
We present the cases of two elderly patients with intermittent long-term tramadol intake against chronic back pain. Over a period of more than two years they experienced fluctuating confusional states and cognitive deficits, reversible only after discontinuation of tramadol. According to the DSM IV-criteria, an unrecognised recurrent tramadol-induced delirium can be diagnosed in both cases. Although tramadol may represent a well established safe therapy for chronic non-malignant pain in the elderly, these cases demonstrate that it should be applied with caution even in healthy subjects.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
