How does chronic kidney disease (CKD) influence the uptake of medications in patients?

Chronic kidney disease (CKD) significantly impacts drug metabolism and elimination due to impaired renal function. As kidney function declines, the ability of the kidneys to filter and excrete medications is also reduced. This leads to a slower elimination of drugs from the body, as they are not being cleared adequately. Consequently, patients with CKD may experience prolonged drug action, which can affect dosing regimens.

When drugs are eliminated slowly, it can result in increased serum concentrations of the medications, potentially leading to therapeutic outcomes but also increasing the risk of adverse effects. Understanding this aspect of CKD is critical for healthcare providers to prevent accumulation and subsequent toxicity of certain medications in affected patients. Moreover, adjustments to medication dosages may be required based on the specific degree of kidney impairment to ensure safe and effective treatment.
