Primidone (Paperback)

High Quality Content by WIKIPEDIA articles! Primidone is an anticonvulsant of the pyrimidinedione class whose active metabolites, phenobarbital (major) and phenylethylmalonamide (PEMA) (minor), are also anticonvulsants. It is used mainly to treat complex partial, simple partials, generalized tonic-clonic seizures, myoclonic, akinetic seizures and since the 1980s it has been a valuable alternative to propranolol in the treatment of essential tremor. Unlike other anticonvulsants such as carbamazepine and valproic acid, primidone is rarely used in the treatment of bipolar disorder or any other psychiatric problem. It is also not widely used in treatment of neuropathic pain, trigeminal neuralgia, or migraine. Primidone has been occasionally used to treat long QT syndrome, cerebral palsy, and athetosis.
