Pharmacokinetics
The following table is only an approximation, for single doses. Tramadol has a predominantly linear pharmacokinetic profile within the therapeutic dosage range, partially due to production of active metabolite M1.
| Route | Onset | Peak | t1/2β | Duration of action |
|---|---|---|---|---|
| IV | Seconds | Immediate | 5-6 hours | 4-8 hours |
| IM | 10-20 mins | 45 mins | 4-8 hours | |
| O | 60 mins | 2-3 hours | 6 hours | |
| O (ER) | 2-4 hours | 6-8 hours | 8-10 hours | 10-14 hours |
