Eptoin 100 Tablet is used to treat epilepsy/seizures, and prevent seizures during/after brain surgery or after traumatic brain injury. Besides this, it may also be used to treat trigeminal neuralgia (facial nerve pain). It contains Phenytoin, which helps prevent neurons from working at a very fast speed, thereby preventing the brain cells from firing together rapidly in an uncontrolled way. As a result, it helps control seizures. In some cases, it may cause certain common side effects such ...

Eptoin acts as an anticonvulsant by increasing efflux or decreasing influx of sodium ions across cell membranes in the motor cortex during generation of nerve impulses; thus stabilising neuronal membranes and decreasing seizure activity. It acts as an antiarrhythmic by extending the effective refractory period and suppressing ventricular pacemaker automaticity, shortening action potential in the heart. EPToin Injection is an anticonvulsant (or anti-epileptic) medicine that works by decreasing the nerve impulses which cause the seizures. By controlling the frequency of seizures, it will help you go about your daily activities with more confidence. It helps reduce symptoms such as confusion, uncontrollable jerking movements, loss of awareness, and fear or anxiety. This medicine is not associated with any physical or psychological dependence (addiction) but it should not be stopped suddenly ...
