Assessing Phenytoin and Levetiracetam Efficacy, Cost-Effectiveness, and CYP2C9/SV2A Polymorphism in Early Post-Traumatic Seizures: A Multicentric Prospective Randomized Trial
Objectives: To evaluate the seizure incidence \& efficacy of the respective anti-epileptic drug in each treatment arm. Assessment of clinical \& functional outcomes, safety profile, and cost-effectiveness in each group. Effect of genetic polymorphisms on seizure incidence among study participants
Methods: A Multicentric prospective randomized placebo-controlled double-blinded clinical trial is planned. After satisfying eligibility criteria and informed consent, TBI patients will be randomly allocated into three arms 'phenytoin arm', 'levetiracetam arm', and 'placebo'. Drug polymorphism will be analyzed in all the patients using quantitative real-time PCR. Expected outcome: This study will provide high-quality evidence in PTS management and will establish the role of prophylactic anti-epileptics in PTS. This study also opens the plethora of undesignated roles of genetic polymorphism in the efficacy and safety of levetiracetam and phenytoin in traumatic brain injury patients.
• Patients of severe blunt TBI with GCS score less than 10.
• Patients with GCS of more than 10 in the presence of computed tomographic imaging findings consistent with brain injury: subarachnoid hemorrhage \[SAH\], subdural hematoma \[SDH\], epidural hematoma \[EDH\], intracerebral hemorrhage \[ICH\], or diffuse axonal injury \[DAI\], depressed skull fracture.
• Patients with penetrating injury.
