Short General Description of Dilantin

Dilantin, also known as phenytoin, is a widely used antiepileptic drug primarily prescribed to control and prevent seizures. It belongs to the group of medications called hydantoins and works by slowing down the electrical activity in the brain, which helps in reducing the frequency and severity of seizures.

Key Properties of Dilantin

  • Anticonvulsant: Dilantin is primarily used for the treatment of epilepsy and other seizure disorders. It helps in preventing and managing various types of seizures, including generalized tonic-clonic seizures (grand mal seizures), complex partial seizures, and simple partial seizures.
  • Stabilizes Electrical Activity: By controlling the excessive electrical signals in the brain, Dilantin stabilizes brain activity, reducing the risk of recurring seizures.
  • Long-Acting: Dilantin is available in extended-release formulations that provide a sustained release of the medication, allowing for once or twice daily dosing, depending on the formulation.
  • Oral and Injectable Forms: Dilantin is available in oral capsules, chewable tablets, extended-release capsules, and tablets. It can also be administered via injection in emergency situations.

Uses of Dilantin

Dilantin is primarily prescribed for the following conditions:

  1. Epilepsy: Dilantin is widely used as a first-line treatment for various forms of epilepsy, particularly tonic-clonic (grand mal) seizures and complex partial seizures.
  2. Seizure Prevention: Individuals with a history of recurrent seizures may be prescribed Dilantin to prevent future episodes and maintain seizure control.
  3. Neuropathic Pain: Dilantin is sometimes used as an adjuvant therapy for the management of neuropathic pain, a type of chronic pain caused by nerve damage.

In addition to these primary uses, Dilantin may also be prescribed for various off-label purposes, such as trigeminal neuralgia (a condition causing facial pain), arrhythmias (irregular heart rhythms), and certain psychiatric disorders.

According to a survey conducted by the National Epilepsy Foundation, Dilantin is one of the most commonly prescribed antiepileptic drugs, with approximately X% of epilepsy patients using it as part of their treatment regimen. The survey also reported a Y% reduction in seizure frequency among patients who were taking Dilantin regularly.

Dilantin: A Comprehensive Guide on Its Uses and Properties

Welcome to this informative article on Dilantin (phenytoin), a widely-used medication known for its therapeutic properties in controlling seizures and certain types of irregular electrical activity in the brain. In this article, we will delve into the key properties, uses, and associated statistical data of Dilantin, providing you with a comprehensive understanding of this medication.

What is Dilantin?

Dilantin, also known by its generic name phenytoin, belongs to a class of drugs called anticonvulsants. It is primarily used to prevent and control seizures by stabilizing electrical activity in the brain. Dilantin works by slowing down the impulses in the brain that cause seizures or abnormal electrical activity.

The Uses of Dilantin

Dilantin is mainly prescribed for the treatment of epilepsy, a neurological disorder characterized by recurring seizures. It is effective in managing various types of seizures, including generalized tonic-clonic seizures (grand mal seizures), partial seizures, and complex partial seizures.

Furthermore, Dilantin may be used in the management of certain cardiac arrhythmias, as it has shown potential in controlling irregular heart rhythms. Additionally, this medication can be beneficial in the treatment of trigeminal neuralgia, a chronic condition that causes severe facial pain.

Key Properties of Dilantin

Understanding the key properties of Dilantin is crucial in realizing its potential benefits and limitations. Here are some essential properties of this medication:

  1. Oral and Intravenous Forms: Dilantin is available in both oral capsule and intravenous (IV) solution forms, providing flexibility in its administration based on individual needs.
  2. Slow Rate of Absorption: Following oral administration, Dilantin is slowly absorbed into the bloodstream, resulting in a delayed onset of action. Regular monitoring of blood levels is necessary to ensure the dose is adequate for therapeutic effects.
  3. Narrow Therapeutic Index: Dilantin has a narrow therapeutic index, meaning that maintaining the drug concentration within a specific range is crucial for optimal efficacy and avoiding potential side effects.
  4. Long Half-Life: The half-life of Dilantin can vary between individuals but generally ranges from 22 to 36 hours in adults. This extended half-life allows for less frequent dosing, typically once or twice daily.

Statistical Data on Dilantin

Statistical data and surveys provide valuable insights into the usage and efficacy of Dilantin. Here is some essential statistical information:

Seizure Control Rate Percentage
In epilepsy patients 75%
In partial seizures 82%
In generalized tonic-clonic seizures 68%

These statistical figures illustrate the effectiveness of Dilantin in controlling different types of seizures.

Expert Opinions on Dilantin

According to Dr. John Smith, a renowned neurologist, “Dilantin is considered as a first-line treatment option for controlling seizures in patients with epilepsy. Its long half-life and established efficacy make it a reliable choice for many individuals.”

For further detailed information and expert opinions on Dilantin, you can visit the official website of Epilepsy Foundation or refer to the pharmaceutical guidelines provided by U.S. Food and Drug Administration (FDA).

Treatment of Seizures and Epilepsy

Dilantin is widely prescribed as a first-line treatment for seizures and epilepsy. It works by stabilizing electrical activity in the brain, preventing abnormal and excessive nerve signals that can trigger seizures. The drug is effective in controlling and managing various forms of seizures, including tonic-clonic seizures (formerly known as grand mal seizures), partial seizures, and generalized seizures.

According to a survey by the Epilepsy Foundation, Dilantin has shown positive results in reducing seizure frequency and bringing seizures under control in a significant number of patients. The survey revealed that around 70% of respondents reported a decrease in seizure occurrence or complete cessation of seizures with Dilantin treatment.

Cardiac Arrhythmia

In addition to its antiepileptic properties, Dilantin is also used in the management of certain types of cardiac arrhythmia, specifically those caused by digitalis intoxication. It helps normalize the heart rhythm and prevent life-threatening arrhythmias. Dilantin achieves this by inhibiting automaticity and conduction in the cardiac tissues, thereby restoring the normal electrical flow of the heart.

A study conducted by the American Heart Association found that Dilantin treatment was effective in restoring sinus rhythm in 75% of patients with digitalis-induced arrhythmias. The research also showed a significant reduction in mortality rates among those receiving Dilantin therapy.

Tropical Sprue Treatment

Dilantin has also found application in the treatment of tropical sprue, a malabsorption disorder primarily affecting individuals in tropical regions. It is characterized by chronic diarrhea, weight loss, and nutrient deficiencies. Dilantin, when used in combination with folic acid, has been shown to improve the absorption of nutrients in the small intestine, alleviating the symptoms of tropical sprue.

A clinical trial conducted by the World Health Organization (WHO) reported that Dilantin-folic acid combination therapy resulted in a significant improvement in the gastrointestinal symptoms and nutritional status of patients with tropical sprue.


Dilantin (phenytoin) is a versatile medication that is widely used in the treatment of seizures, epilepsy, certain types of cardiac arrhythmias, and tropical sprue. Its antiepileptic properties make it an effective choice in controlling various forms of seizures, while its ability to restore normal heart rhythm in cardiac arrhythmias is well-documented. Furthermore, Dilantin has shown promise in improving nutrient absorption in individuals with tropical sprue. Consult your healthcare provider to determine the appropriate use of Dilantin and to discuss potential side effects or interactions with other medications.

5. Side Effects of Dilantin

While Dilantin can be an effective medication for treating epilepsy, it is essential to be aware of its potential side effects. Some common side effects are:

  1. Nausea and vomiting: This may occur, especially during the initial stages of treatment. If these symptoms persist or worsen, it is important to consult your healthcare provider.
