- Tramadol is a centrally acting synthetic analgesic compound. Although its mode of action is not completely understood, at least two complementary mechanisms appear applicable: binding of parent and M1 metabolite to opioid receptors and weak inhibition of reuptake of norepinephrine and serotonin.
- hypersensitivity to tramadol
- Seizure Risk: Seizures have been reported in patients receiving tramadol within the recommended dosage range. The risk of convulsions may be increased in patients with epilepsy, those with a history of seizures, or in patients with a recognized risk for seizure (such as head trauma, metabolic disorders, alcohol and drug withdrawal, CNS infections).
- Anaphylactoid Reactions: Serious and rarely fatal anaphylactoid reactions have been reported in patients receiving therapy with tramadol.
- General: Administer tramadol cautiously in patients at risk for respiratory depression. In cirrhotic patients, dosing reduction is recommended. Reduce dose and / or increase dosing interval
- Laboratory Tests: No tests additional to routine ICU tests are required
- Drug/Laboratory Test Interactions: None known
IMPORTANT DRUG INTERACTIONS FOR THE ICU
- Concomitant use of tramadol increases the seizure risk in patients taking selective serotonin reuptake inhibitors and tricyclic antidepressants.
- Synergistic with other CNS depressant drugs.
- Post-marketing surveillance has revealed rare reports of digoxin toxicity and alteration of warfarin effect, including elevation of prothrombin times.
- Body as a Whole: Itch
- Cardiovascular: Hypotension, Tachycardia
