Which of the following is the FALSE statement regarding tramadol (Ultram)?

• A. Ondansetron may interfere with part of tramadol's analgesia
• B. Tramadol is associated with seizures in patients taking selective serotonin reuptake inhibitors (SSRI)
• C. It exhibits monoamine oxidase (MAO) inhibiting effects
• D. It is relatively safe in patients whose pain makes them suicidal

Answer: (D)

Tramadol works through two main ways: it’s a weak mu-opioid receptor agonist and it also inhibits reuptake of serotonin and norepinephrine, giving it a distinctive dual action. That serotonergic activity helps explain why ondansetron, a 5-HT3 antagonist, can blunt part of tramadol’s analgesic effect—blocking the serotonin-mediated component reduces pain relief from tramadol. The same serotonergic and noradrenergic effects explain why combining tramadol with selective serotonin reuptake inhibitors raises the risk of seizures and other serotonergic interactions. Some references note that tramadol has weak monoamine oxidase inihibiting properties, which can contribute to interactions with other monoaminergic drugs, though this is not the primary way it provides analgesia. It is not, however, considered safe in patients whose pain is tied to suicidal ideation. Opioids carry overdose risk, and in someone with suicidality the potential for fatal overdose, respiratory depression, and mood-related risks makes tramadol unsuitable as a safe choice.
