Generic of tramadol?

Tramadol is itself a generic opioid‑analgesic drug. It’s sold worldwide under many brand names, but the chemical name (tramadol hydrochloride) is the generic.

| Form | Common brand names (US) | Common brand names (other regions) | Typical dosage (tablet) |
|------|------------------------|------------------------------------|------------------------|
| 50 mg tablet | Ultram® | Tramadol‑HCl (various local brands) | 50 mg |
| 100 mg tablet | ConZip® | Tramadol 100 mg (generic) | 100 mg |
| 100 mg capsule (extended‑release) | Ultram ER® | Tramadol ER | 100 mg |
| 100 mg capsule (immediate‑release) | Tramal® | Tramadol IR | 100 mg |
| 50 mg capsule (immediate‑release) | Tramadol 50 mg | 50 mg |

Key points:
* Tramadol is the generic name (tramadol hydrochloride).
* It is available as both immediate‑release (IR) and extended‑release (ER) formulations.
* The drug is a centrally acting analgesic that works as a weak µ‑opioid receptor agonist plus it inhibits the reuptake of serotonin and norepinephrine, which contributes to its pain‑relieving effect.
* Tramadol is not a “generic of tramadol” because the generic is the drug itself. The list above shows the most common brand names you might see on a prescription or in a pharmacy.
