Final answer:
Phenytoin/fosphenytoin is an enzyme reducer and works by inhibiting certain enzymes in the body. This can lead to altered drug levels and affect how the drug is processed and eliminated. Pharmacists and healthcare providers need to be aware of these effects and may monitor the patient's drug levels more closely or adjust the dosage if necessary.
Step-by-step explanation:
Phenytoin/fosphenytoin is an enzyme reducer and works by inhibiting certain enzymes in the body. When a drug inhibits an enzyme, it decreases the activity of that enzyme. In the case of phenytoin/fosphenytoin, it reduces the activity of enzymes involved in the metabolism of the drug. This can lead to altered drug levels in the body and affect how the drug is processed and eliminated.
When a pharmacist or healthcare provider encounters a patient taking phenytoin/fosphenytoin, they need to be aware of these enzyme inhibiting effects. They may monitor the patient's drug levels more closely, adjust the dosage if necessary, or consider potential drug interactions that could be affected by the reduced enzyme activity.
