Give an example of the effect of drugs on nutrient metabolism


Drugs can interfere with macronutrient, vitamin, and mineral metabolism. For example, corticosteroids increase the rate of gluconeogenesis, resulting in hyperglycemia and increased nitrogen loss. Numerous medications interfere with vitamin and mineral metabolism. Phenytoin (Dilantin), used for treatment of seizures, inhibits both vitamin D and folate metabolism. Long-term use may result in megaloblastic anemia secondary to folate deficiency.
