Aminohippurate sodium (PAH) is used in plasma concentrations of 10-20 ug/ml to estimate effective renal plasma flow (ERPF) which is an index of renal function. In these low plasma concentrations, PAH is extracted almost completely from the plasma with each passage through functional renal tissue, and the value obtained for PAH clearance is accepted as being numerically equal to the ERPF. In plasma concentration of 400-600 ug/ml, PAH is used in conjunction with glomerular filtration rate (GFR) measurements to estimate the functional capacity of the renal tubular secretory mechanism. Since PAH is excreted both by tubular secretion and glomerular filtration, tubular transport capacity can be determined by comparing PAH excretion with values for GFR obtained by inulin clearance. Although this test may be the best quantitative measure of functioning nephron mass, its complexity prevents its widespread use. PAH clearance tests are more accurate but also more complex than phenolsulfonphthalein excretion tests for evaluation of renal blood flow. In most clinical situations, simpler (although less precise) methods of renal function evaluation are used.

Adverse reactions which have been reported in association with the administration of aminohippurate sodium (PAH) include nausea, vomiting, cramps, vasomotor disturbances, flushing, tingling, a sensation of warmth, and the desire to defecate or urinate during or shortly after administration of the drug.

PAH must be administered with caution in patients with low cardiac reserve, since a rapid increase in plasma volume may precipitate congestive heart failure. The large dose required to achieve the plasma concentrations necessary for the determination of the maximum tubular secretion should be administered slowly and with caution, and the patient should be continuously observed for any adverse reactions. PAH is contraindicated in patients with known hypersensitivity to the drug or any ingredient in the formulation.

Used to measure effective renal plasma flow (ERPF) and to determine the functional capacity of the tubular excretory mechanism.
Aminohippurate (p-aminohippuric acid, PAH, PAHA) is the glycine amide of p-aminobenzoic acid. It is filtered by the glomeruli and is actively secreted by the proximal tubules. At low plasma concentrations (1.0 to 2.0 mg/100 mL), an average of 90 percent of aminohippurate is cleared by the kidneys from the renal blood stream in a single circulation. It is ideally suited for measurement of ERPF since it has a high clearance, is essentially nontoxic at the plasma concentrations reached with recommended doses, and its analytical determination is relatively simple and accurate. Aminohippurate is also used to measure the functional capacity of the renal tubular secretory mechanism or transport maximum (TmPAH). This is accomplished by elevating the plasma concentration to levels (40-60 mg/100 mL) sufficient to saturate the maximal capacity of the tubular cells to secrete aminohippurate. Inulin clearance is generally measured during TmPAH determinations since glomerular filtration rate (GFR) must be known before calculations of secretory Tm measurements can be done.
Indicators and Reagents
Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant and Hackh's Chemical Dictionary, 5th ed, p301, p499) (See all compounds classified as Indicators and Reagents.)
