General description of Dilantin:

Dilantin, also known as phenytoin, is an anti-seizure medication used to treat various types of seizures, including tonic-clonic (grand mal), partial (focal), and psychomotor seizures. It belongs to a class of medications called hydantoins and works by stabilizing electrical activity in the brain to prevent excessive and abnormal firing of neurons.

Uses of Dilantin

1. Treatment of Epilepsy

Dilantin is primarily used in the treatment of epilepsy, a neurological disorder characterized by recurrent seizures. It is effective in controlling various types of seizures, including tonic-clonic (grand mal), complex partial, and other types of generalized seizures.

2. Prevention of Seizures Post Brain Surgery

Following brain surgery, patients may be at risk of seizures due to the trauma caused to the brain. Dilantin is often prescribed to prevent seizures in such cases.

3. Management of Arrhythmias

In some cases, Dilantin may be used off-label for the management of certain types of cardiac arrhythmias. It exhibits anti-arrhythmic properties that can help regulate abnormal heart rhythms.

4. Neuropathic Pain Relief

Dilantin has been found to be effective in relieving neuropathic pain, a type of chronic pain caused by nerve damage. It can be used as an adjuvant therapy for pain management.

5. Treatment of Status Epilepticus

Status epilepticus is a medical emergency characterized by prolonged seizures. Dilantin may be administered in this situation to help control the seizures and prevent further complications.

6. Prophylaxis for Dental Procedures

Some individuals with a history of certain types of heart conditions may require prophylactic treatment with Dilantin prior to dental procedures to prevent the risk of bacterial endocarditis.

7. Off-label Uses

In addition to the approved indications, Dilantin may be used off-label for conditions such as bipolar disorder, trigeminal neuralgia, and certain types of movement disorders.

It’s essential to follow the prescribing doctor’s recommendations and not engage in self-medication or alter the dosage without medical supervision.

Pharmacokinetics of Dilantin

“Dilantin has a complex pharmacokinetic profile that involves absorption, distribution, metabolism, and elimination processes. Let’s delve deeper into each aspect to better understand how Dilantin works in the body.”


“When administered orally, Dilantin is rapidly absorbed in the gastrointestinal tract, with peak plasma concentrations typically reached within 4 to 12 hours. Food can affect the rate and extent of absorption, so it is recommended to take Dilantin on an empty stomach to minimize variability.”


“Dilantin has a high protein binding capacity, primarily to albumin, resulting in limited distribution to tissues. The drug crosses the blood-brain barrier and placenta, reaching therapeutic levels in the central nervous system and potentially affecting fetal development during pregnancy.”


“Dilantin undergoes hepatic metabolism mainly through the cytochrome P450 enzyme system, specifically CYP2C9 and CYP2C19. The drug is converted to its active form, phenytoin, which exhibits nonlinear kinetics at therapeutic doses, making individualized dosing crucial to maintaining effective plasma levels.”
