Zen Retard-200 Tablet 10's belongs to a group of medicines called anticonvulsants or anti-epileptics used to treat epilepsy (fits) and trigeminal neuralgia (pain in the face's nerves). Epilepsy is a neurological disorder in which there is a sudden rush of electric impulses (electric activity) in the brain. As a result, the brain's electrical rhythms become imbalanced, resulting in recurrent episodes of seizures or fits. Trigeminal neuralgia is a condition which affects the trigeminal nerve that carries sensations from the face to the brain. Zen Retard-200 Tablet 10's contains 'Carbamazepine' that reduces the electrical impulses and subsequent firing of the nerve impulses that cause fits. Thus, Zen Retard-200 Tablet 10's decreases the excessive and abnormal nerve activity in the brain, thereby controlling seizures.
