Primidone

Primidone (INN, BAN, USP) is an anticonvulsant of the barbiturate class. It is a structural analog of phenobarbital and related to barbiturate-derivative.

It can also cause elevations in hepatic enzymes such as gamma-glutamyl transferase and alkaline phosphatase. In 1981, it was shown that phenobarbital, one of primidone's metabolites, only induced a significant porphyrin at high concentrations in vitro. It was first reported to exacerbate hepatic porphyria in 1975.

In a subsequent pilot trial in which children who experienced improvement were switched to placebo, the results were much more disappointing, with the two subjects who experienced subjective improvement also experiencing this on placebo.

Mysoline (Primidone) Side Effects, Interactions, Warning, Dosage

Mysoline (primidone) is a white, crystalline, highly stable substance, M.P. 279-284°C. It is poorly soluble in water (60 mg per 100 mL at 37°C) and in most.

Store MYSOLINE at room temperature between 68°F to 77°F (20°C to 25°C) in a tight, light-resistant container.

The total daily dosage should not exceed 2 g. Since Mysoline therapy generally extends over prolonged periods, a complete blood count and a sequential multiple analysis-12 (SMA-12) test should be made every six months.

The prescribing physician will wish to weigh these considerations in treating or counseling epileptic women of childbearing potential. Neonatal hemorrhage, with a coagulation defect resembling vitamin K deficiency, has been described in newborns whose mothers were taking primidone and other anticonvulsants.
