Abstract:
The concept of renal functional reserve (RFR) was introduced in the 80's. The renal functional reserve was defined as the ability of the kidney to increase Renal Plasma Flow (RPF) and Glomerular Filtration Rate (GFR) after a stimulus as a protein load. The absence of RFR defines a state of hyperfiltration which seems to be a detrimental factor for the progression of renal failure. The measure of RFR by a protein load test is thus a mean to detect glomerular hyperfiltration and allows to give adequate diet prescription.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
