dc.description.abstract | Tc-99(m)-p-aminohippuric acid (Tc-99(m)-PAH) is a new renal radiopharmaceutical prepared from a lyophilized kit by the addition of sodium pertechnetate ((NaTcO4)-Tc-99-O-m. Each vial contains PAH, the calcium trisodium salt of diethylenetriamine pentaacetic acid (CaNa(3)DTPA) and stannous chloride (SnCl2. 2H(2)O) in an inert atmosphere. It is a stable radiopharmaceutical with high radiochemical purity ( GT 95%). Its protein binding is very similar to that of I-131-OIH, but it is hydrophilic in character. Animal studies using Tc-99(m)-PAH have indicated that it provides renal images of satisfactory quality with no external background. Despite its almost identical radiochemical purity and HPLC analysis results to Tc-99(m)-DTPA, Tc-99(m)-PAH is rapidly secreted by the kidneys in a manner consistent with tubular secretion, as confirmed by rat probenecid studies, whereas Tc-99(m)-DTPA is excreted by glomerular filtration. The pharmacokinetic parameters of Tc-99(m)-PAH (t(1/2(alpha))) = 2.5 min, t(1/2(beta)) = 41.7 min, Cl = 5.22 ml . min(-1), K-el 5.1 x 10(-4) min(-1)) differ from those of Tc-99(m)-DTPA. Evaluation of Tc-99(m)-PAH in two human volunteers confirmed its good renal characteristics: rapid disappearance from the vascular system, high uptake in kidneys followed by its very fast elimination, and low residual activity 20 min after its intravenous administration.
