Zero order kinetics occur in following drug with high dose: (A) Phenytoin and theophylline, (B) Digoxin and prapranol, (C) Amiloride and probenecid, (D) Lithum and thiophylline
Answer is A. Phenytoin and thiophylline follows zero order kinetics with high dose as it follow linear with time Ref -KDT 6/e p31,138
