TEGRETOL CR 400MG is a higher-strength controlled-release tablet of carbamazepine, designed for patients requiring a more potent dose to manage severe epilepsy or neuropathic pain. This formulation ensures consistent drug release over 12–24 hours, enhancing efficacy and tolerability compared to immediate-release alternatives. It is particularly beneficial for patients with frequent seizures or those who experience breakthrough episodes with lower doses. The 400MG strength is often prescribed for maintenance therapy in adults and adolescents.
