Because the outcome of barbiturates about the metabolism of phenytoin is not really predictable, phenytoin and barbiturate blood ranges must be monitored additional commonly if these drugs are provided concurrently.

Experimental Design and style: Appropriate controls and replicates are crucial to ensure strong and reproducible success. Aspects including the age, sex, and overall health status of the donor monkeys can affect microsomal enzyme activity.

The excretion of unmetabolized barbiturate is just one characteristic that distinguishes the prolonged-acting category from Those people belonging to other categories, which are Just about entirely metabolized. The inactive metabolites with the barbiturates are excreted as conjugates of glucuronic acid.
