Primirus 50 Tablet is used to control various epileptic conditions (fits), prevent seizures and treat shaking attacks (essential tremors). Epilepsy is a central nervous system disorder characterized by a sudden rush of electrical activity in the brain, leading to seizures, unusual behaviour, and loss of awareness. Primirus 50 Tablet is ineffective for treating absence (petit mal) seizures.

Primirus 50 Tablet contains 'Primidone', which increases the activity of a chemical messenger (GABA) that suppresses the brain's excessive and abnormal activity of nerve cells. Our brain cells (neurons) work by firing at a certain rate to function normally. However, during an epileptic attack or seizure, our neurons are forced to work rapidly compared to normal conditions. Primirus 50 Tablet prevents neurons from working at a very fast speed, thereby preventing all brain cells from firing together rapidly in an uncontrolled way. As a result, episodes of seizures are stopped at their initial point only.

Epilepsy: It is a central nervous system disorder in which brain activity becomes abnormal, leading to rapid fits/seizure episodes with unusual behaviour and loss of awareness. Fits/Seizure is a sudden rush of electrical activity in the brain. Lack of sleep, high fever, stress, bright lights, caffeine, certain medicines, alcohol, and skipping meals/overeating are a few of the most common triggers for seizures. The possible causes of epilepsy include traumatic brain injury, scarring on the brain after a brain injury, high fever, stroke, vascular diseases, lack of oxygen to the brain, brain tumours, and genetic disorders.
