Which of the following about phenytoin is true ?
Ans. is 'a' i.e., It follows zero order kinetics Phenytoin is metabolized in liver by hydroxylation and glucuranide conjugation (option 'c' is incorrect) o This drug follows saturation kinetics (kinetics changes from first order to zero order within therapeutic concentrations) Phenytoin is an enzyme inducer and induces the metabolism of many drugs. Phenytoin is a known teratogenic and produces fetal hydantoin syndrome.
It follows zero order kinetics
Not an hepatic enzyme inducer
It is excreted unchanged in urine
It is not teratogenic
