CERETEC vs NEUROLITE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Technetium-99m exametazime (Ceretec) is a lipophilic radiopharmaceutical that crosses the blood-brain barrier and is taken up by brain tissue in proportion to regional cerebral blood flow. Once inside cells, it undergoes intracellular conversion to a hydrophilic form, trapping it in the brain and allowing SPECT imaging.
NEUROLITE is a sodium channel blocker that stabilizes neuronal membranes and inhibits the release of excitatory neurotransmitters, thereby reducing neuronal excitability and seizure propagation.
555-740 MBq (15-20 mCi) intravenously as a single dose for SPECT imaging.
300 mg orally twice daily.
