Strategies for reducing polypharmacy and other medication-related problems in chronic kidney disease.

Medication-related problems are very common in patients with chronic kidney disease (CKD). These problems are often avoidable and can result in detrimental patient consequences and high financial costs. Despite these risks, it is often medically necessary to prescribe multiple medications to treat the comorbid conditions that accompany CKD. In addition, patients' use of nonprescription medications and changes in pharmacokinetic and pharmacodynamic parameters may further contribute to medication-related problems in CKD, including drug interactions and the need for dosage adjustments. A structured medication assessment process is one approach to reducing the risks associated with medication-related problems. This multifaceted process involves a comprehensive medication history interview, structured therapy assessment, and open communication between members of the medical team. A detailed description of this process is provided to aid healthcare providers in addressing this important issue.
