Below is the list of medicines, which contains Phenytoin as ingredient
Phenytoin is an anticonvulsant which is known to prevent seizures by causing a voltage-dependent block of voltage gated sodium channels. It acts by increasing sodium efflux from the neurons of the motor cortex which reduces the post-tetanic potentiation at synapses. This inhibits the cortical seizure foci from spreading to adjacent areas, thus stabilizing the threshold against hyperexcitability.
Whenever you take more than one medicine, or mix it with certain foods or beverages, you"re at risk of a drug interaction.
