<prompt> Regarding phenytoin, false is:Induces microsomal enzymesAt very low doses, zero order kinetics occurHigher the dose, higher is the half lifeHighly protein bound  <response>: 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. REF: KATZUNG 14TH ED.
