Phenyquin Introduction, Uses, and Mechanisms of Action
Phenyquin is an anticonvulsant drug of the hydantoin class used to prevent and control seizures by changing the electrical activity of the brain. Its primary uses are for treating those with epilepsy, tonic-clonic seizures, and a type of seizure called absence seizures. It is also used in adults to treat certain types of nerve pain, trigeminal neuralgia. It may also be prescribed to prevent seizures resulting from a head injury or brain tumor.
Phenyquin’s mechanism of action is not fully understood, but it is believed to act on the sodium channels in nerve cells that control nerve impulses, resulting in a decrease in electrical excitability and an increase in the seizure threshold.
How Long Does it Take to Work?
Phenyquin usually starts to work within 24 to 48 hours; effects are typically not seen sooner. The full effects of the drug may not be seen for up to a month. It may take several weeks before the optimal dose of phenytoin is found; during this time, the person's symptoms may not fully improve or may worsen.
Absorption, Route of Elimination, Dosage, Administration, and Side Effect
Phenyquin is readily absorbed, reaching peak levels within 90 minutes of administration. It is structurally related to the vitamin D group of molecules, so it is important to limit exposure to direct sunlight or UV radiation while taking phenytoin. It undergoes extensive hepatic metabolism and is eliminated primarily in the urine.
The dosage of phenytoin varies depending on the patient’s age and medical condition. It should be administered orally as 50 mg, 100 mg, or 250 mg tablets or extended-release capsules and the dosage prescribed should be taken exactly as directed. Common side effects may include nausea, vomiting, dizziness, drowsiness, headaches, constipation, and blurred vision.
