Effects of anticonvulsant drugs on calcium transport and polyphosphoinositide metabolism in rat cortical synaptosomes.


1. Anticonvulsants: phenytoin, phenobarbital, carbamazepine and valium at concentrations of 10-100 microM had a significantly inhibitory effect on both K+-stimulated Ca2+-uptake and 32Pi incorporation into phospholipids of rat cortical synaptosomes. 2. Other anticonvulsant, valproic acid, at concentration upto 100 microM had no effect on these two events. 3… (More)
