Impact of Kidney Disease on Drug Pharmacokinetics

Abstract

Background: Kidney failure dramatically alters the pharmacokinetics of drugs by decreasing the organ's ability to filter, reabsorb, and eliminate molecules. The kidneys in significant part control eliminating water-soluble drugs and metabolites. Decline in renal function can lead to reduced pharmacological efficacy, accumulation of medications, and increased toxicity. Moreover, affected by kidney disease are drug absorption, distribution (because of changes in plasma protein binding), metabolism (especially in severe cases), and renal clearance. Reducing adverse effects in affected persons and optimizing therapy dosage depend on an awareness of these changes.
Aim: Emphasizing changes in absorption, distribution, metabolism, and excretion, one can investigate how renal illness affects the pharmacokinetics of different medications. This work also seeks to shed light on dosage modification techniques and factors related to safe pharmacological control for individuals with compromised renal function.
Conclusion: Mostly by lowering renal clearance and changing plasma protein binding, kidney illness greatly influences the pharmacokinetics of medications, hence increasing the free (active) drug concentration. These alterations need for customized medication dosage depending on degree of renal damage. Renal function tests include glomerular filtration rate (GFR) and drug level monitoring where relevant help healthcare professionals prevent toxicity while maintaining therapeutic efficacy. Improving patient outcomes calls for more study and development of renal-safe medications and policies.
