Summary

This study aims to evaluate the efficacy and safety of levetiracetam for the prevention of postoperative seizures in adult patients undergoing supratentorial brain tumor surgery. It is a multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. Eligible participants will be randomly assigned in a 1:1 ratio to receive levetiracetam or placebo, starting 1 hour before surgery and continuing for 3 months postoperatively. The primary outcome is the incidence of clinical seizures within 3 months after surgery. Secondary outcomes include subclinical seizures within 7 days and 3 months postoperatively, adverse events within 3 months, and health economic outcomes. The study aims to clarify the role of levetiracetam in the primary prevention of perioperative seizures in brain tumor patients and to provide evidence for rational use of antiseizure medications in neurosurgical practice.

Conditions

  • Postoperative Seizures After Brain Tumor Surgery

Interventions

DRUG

Levetiracetam

Levetiracetam 500 mg (5 mL) for intravenous infusion administered 1 hour before surgery and again on the evening after surgery (approximately 20:00-22:00), diluted in 100 mL 0.9% sodium chloride or 5% glucose and infused over about 15 minutes. From postoperative day 2 through 3 months, oral levetiracetam tablets 0.5 g twice daily (or via nasogastric route if oral intake not feasible) are administered.

DRUG

Placebo

Matching placebo solution (5 mL) for intravenous infusion 1 hour before surgery and again on the evening after surgery (approximately 20:00-22:00), diluted in 100 mL 0.9% sodium chloride or 5% glucose and infused over about 15 minutes. From postoperative day 2 through 3 months, matching placebo tablets are given twice daily (oral or via nasogastric route). Placebo formulation, packaging, and administration schedule are identical to those of levetiracetam.
