Phenytin capsules is an effective antiepileptic medication widely used to control certain types of seizures in adults and children with epilepsy. Epilepsy is a neurological disorder characterized by abnormal electrical activity in the brain, leading to recurrent seizures. Phenytoin works by stabilizing the membranes of nerve cells in the brain and reducing the spread of excess electrical activity, thereby helping to prevent seizures or reduce their frequency and severity. Phenytoin belongs to a group of medications called hydantoins and has been used for decades as a cornerstone of epilepsy management.
Active ingredients in Phenytin capsules
Each Phenytin capsule contains:
Phenytoin: The main active ingredient. Phenytoin works by prolonging the inactivation period of voltage-gated sodium channels in nerve cells. This reduces the ability of nerve cells to fire rapid, repetitive electrical impulses, the hallmark of epileptic activity. Available Strengths
Phenytoin capsules are available in various strengths to meet different dosage needs:
25 mg
50 mg
100 mg
In addition to capsules, other dosage forms of Phenytin may be available, such as:
Oral suspension: Often used for children or patients who have difficulty swallowing capsules.
Intravenous injection: Used in emergency situations to rapidly control acute seizures or during and after neurosurgery.
Indications for Use of Phenytin Capsules
Controlling grand mal seizures (grand mal seizures): Phenytoin is effective in preventing this type of seizure characterized by loss of consciousness and violent muscle spasms.
Controlling complex partial seizures: Helps reduce the frequency of these seizures, which begin in one part of the brain and may result in loss of consciousness, altered consciousness, and spontaneous behaviors.
Preventing seizures that may occur during or after neurosurgery: Sometimes used as a preventative measure to prevent seizures associated with brain surgery.
