Regarding phenytoin, false is:
*Phenytoin follows saturation kinetics (kinetics changes from first order to zero within therapeutic concentration), Zero order kinetics are seen at high doses. *It is also a potent enzyme inducer and can increase the metabolism of various drugs. *It is 80-90% plasma protein bound.

Central Nervous system
Induces microsomal enzymes
At very low doses, zero order kinetics occur
Higher the dose, higher is the half life
Highly protein bound
At very low doses, zero order kinetics occur
