Leotoin 50 (Phenytoin Sodium) is an antiepileptic medication. It controls and prevents seizures by stabilizing nerve membranes in the brain and blocking the spread of abnormal electrical activity. It is primarily used to manage focal seizures, generalized tonic-clonic seizures, and status epilepticus.
Mechanism of Action
Sodium Channel Blockade: It prolongs the inactivation state of voltage-gated sodium channels in neuronal membranes.
Decreased Excitability: This blocks the repetitive, high-frequency firing of action potentials.
Calcium Flux: It may also reduce calcium influx across neuronal membranes during depolarization.
Pharmacokinetics
Absorption: Absorption is slow but nearly complete after oral administration. Peak concentrations usually occur in 1.5 to 3 hours.
Distribution: It is highly bound to plasma proteins, primarily albumin (about 90%).
Metabolism: Phenytoin is extensively metabolized in the liver by the cytochrome P450 system (mainly CYP2C9 and to a lesser extent CYP2C19) into inactive metabolites.
Excretion: It is primarily excreted by the kidneys as inactive metabolites.
Pharmacodynamics and Elimination :
Zero-Order Kinetics: At therapeutic doses, phenytoin exhibits capacity-limited (zero-order) pharmacokinetics. Its metabolic enzymes can become saturated.
Non-Linear Changes: Small dosage increases can lead to disproportionately large increases in plasma concentrations, increasing the risk of toxicity.
Dosing and Monitoring
Therapeutic Range: The typical therapeutic serum concentration is 10 to 20 μ g/mL.
Monitoring: Requires therapeutic drug monitoring (TDM) to prevent adverse effects like nystagmus and ataxia.
Dosage Forms: Available in various forms including oral tablets and as an injectable solution for intravenous use
