CAS 125-33-7: Primidone
Description:Primidone is an anticonvulsant medication primarily used in the treatment of epilepsy and essential tremors. It is a white to off-white crystalline powder that is soluble in water and alcohol, with a molecular formula that reflects its organic nature. The substance acts as a prodrug, being metabolized in the liver to phenobarbital, which contributes to its therapeutic effects. Primidone exhibits a mechanism of action that involves the modulation of neurotransmitter activity, particularly enhancing GABAergic transmission, which helps stabilize neuronal excitability. Its pharmacokinetics include oral administration, with a relatively long half-life, allowing for once or twice daily dosing. Common side effects may include sedation, dizziness, and gastrointestinal disturbances. Due to its potential for dependence and withdrawal symptoms, careful monitoring is essential during treatment. Primidone is classified under the category of barbiturates, and its use should be approached with caution, particularly in patients with a history of substance abuse or certain medical conditions.
