Furthermore, Tramadol (and metabolites) remain detectable for up to 40 hours after administration at the threshold of 12.5 pg. Assuming you excrete Tramadol at an average rate, it should be out of your urine within 2 days (48 hours) of ingestion.
The half life of tramadol is in the range of 5 to 8 hours,.. so the mean half life is about 6.3 hours (in the blood plasma) -- and it's metabolite(s) are around 6.8-7.5 hours. A 50mg dose of tramadol is distributed at a rate of about 1.3liters/kg and slightly higher for women. The drug binds to plasma proteins at about 20% efficiency. Roughly 30% (give or take) remains unchanged and is excreted in a first pass metabolic process via urine.
