Impairment of memory &/or intellectual functions Initially 4.8 g/day in several intakes during the 1st wk of treatment. Maintenance: 2.4 g daily in 2 or 3 divided doses, eventually reducing to 1.2 g daily.
Treatment of myoclonus of cortical origin Initially 24 g/24 hr for 3 days. If the response on the 3rd day is weak or absent, continue administration up to the 7th day. If there is still no response or it is inadequate, discontinue treatment on the 7th day. To determine mean active dose: From the day when the dose of 24 g has shown to be active, it should be decreased by 1.2 g every 2 days until myoclonus reappears. Daily dose should be divided into 2 or 3 single doses.
Childn 8-13 yr w/ learning difficulties 3.3 g daily.
