Head-to-head evidence
Oxcarbazepine (Oxtellar XR) vs Oxcarbazepine (Trileptal)
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

Oxcarbazepine (Oxtellar XR)
Marketed by Supernus Pharmaceuticals
NCT00772603 · Phase 3 · completed
The trial was randomized, quadruple-blind, placebo-controlled, and included 366 participants, with seizure frequency as a clinical primary endpoint. The 2,400-mg comparison significantly favored oxcarbazepine, while the 1,200-mg comparison did not, so the primary result was mixed rather than consistently positive.
Oxcarbazepine (Trileptal)
Marketed by Novartis
NCT00050934 · Phase 3 · completed
The study enrolled 132 participants and measured the clinical outcome of seizure-frequency change, but the registry does not document randomization, blinding, or a comparator arm. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
